STUDIES ON THE ECOLOGY OF LARVAL MYCTOPHIDS (PISCES, MYCTOPHIDAE): A PROPOSAL FOR NEW RESEARCH LINES IN THE HUMBOLDT CURRENT
Provedor de dados: 72
Autores: Rodríguez,Laura; Castro,Leonardo.
This is a review on some biological and ecological characteristics of the early life stages of myctophids that exemplify their adaptations to coastal upwelling zones and oceanic nearby areas. The approach has been, however, not to make an exhaustive list of all possible research subjects but, in a more pragmatic way, a) to identify relevant aspects that can be approached with currently available methods in the region and, b) through examples of studies published nationally and regionally, to stimulate future research in larval ecology in the Humboldt Current. Three major themes were assessed: taxonomy and systematics, population ecology and reproductive strategies and, ecophysiology of the early life stages. Among the former, we detected a lack of...

Видовой состав рыб как показатель современного состояния прибрежной экосистемы юго-западного шельфа Крыма
Provedor de dados: 13
Autores: Гордина, А. Д.; Салехова, Л. П.; Климова, Т. Н.
На основании ихтиопланктонных исследований и отлова взрослых рыб дана характеристика ихтиофауны двух участков прибрежных вод Севастополя (полузамкнутой акватории Севастопольской бухты и открытой части моря, прилегающей к ней)  в мае – октябре 2003 г. Установлено, что по сравнению с 80 – 90-ми годами ХХ столетия значительно расширился видовой состав рыб. Возросла значимость промысловых видов – хамсы и ставриды, увеличилась доля рыб – мигрантов из Мраморного моря (пеламиды и луфаря). Зарегистрирована икра обычно редкого в планктоне вида – морского петуха. Видовой состав рыб оказался сопоставим с данными благополучных 50 – 60-х годов прошлого столетия, что свидетельствует об оздоровлении прибрежной экосистемы Черного моря.

Долговременные изменения летнего ихтиопланктона в районе бухты Круглая (Севастополь, Черное море)
Provedor de dados: 13
Autores: Климова, Т. Н.
Рассмотрена многолетняя динамика видового состава, численности и состояние летнего ихтиопланктона в 1986, 1990, 1994, 1998 – 2003 гг.  в районе бухты Круглая, Севастополь (юго-западное побережье Крымского п-ова, Черное море). Увеличение видового разнообразия ихтиопланктона и средней численности пелагической икры рыб в последние шесть лет (1998 – 2003 гг.) до уровня 60 – 70-х годов ХХ века дают основание предположить, что популяции летненерестующих видов рыб восстанавливаются в этом районе. Однако высокая смертность икры и низкая численность личинок рыб свидетельствуют о неблагоприятных условиях для их эмбрионального и постэмбрионального развития.

Ихтиопланктон прибрежной акватории юго-западного Крыма в 2002 – 2008 гг.
Provedor de dados: 13
Autores: Климова, Т. Н.
На основании литературных данных и материалов мониторинговых исследований 2002 – 2008 гг. проанализировано современное состояние ихтиопланктона в прибрежной зоне юго-западной части Крымского п-ова (Севастопольский регион) и показана динамика его численности, выживания и видового разнообразия. Отмечены среднегодовой рост численности, как икры, так и личинок рыб, и восстановление видового состава до уровня 1960-х годов (коэффициент видового сходства – 0.9). Положительные изменения в видовом разнообразии ихтиопланктона и логнормальное распределение видов по значимости свидетельствуют об относительной стабильности состояния ихтиопланктона в исследованный период. Однако уменьшение доли личинок ранее доминирующих промысловых видов-мигрантов в пользу личинок...

Fluctuations d'abondance de l'ichtyoplancton sur une zone frontale cotiere (Golfe de Gascogne: Baie d'Audierne)
Provedor de dados: 5
Autores: Camus, Patrick; Delpech, Jean-paul; Omnes, Marie-helene; Mastail, Max.
A two years ichthyoplankton sampling program over an eight station network on each side of a coastal tidal front was conducted twice a month during neap tides. A principal component analysis was performed on the data (taxa and observations) which were segregated during the summer into two groups of taxa related to two groups of stations belonging to two different hydrodynamical areas. In July and August 1980 during a tide cycle, zooplankton was investigated at two stations in the stratified and transitional area. Periodic fluctuations of meroplanktonic taxa correlated to the movement of the front induced by the tide were observed.

Autores: Koeck, Barbara; Gerigny, Olivia; Durieux, Eric Dominique Henri; Coudray, Sylvain; Garsi, Laure-helene; Bisgambiglia, Paul-antoine; Galgani, Francois; Agostini, Sylvia.
The Strait of Bonifacio constitutes one of the rare transboundary Marine Protected Areas (MPA) of the Mediterranean Sea (between Sardinia, Italy and Corsica, France). Based on the hypothesis that no-take zones will produce more fish larvae, compared to adjacent fished areas, we modeled the outcome of larvae released by coastal fishes inside the no-take zones of the MPA in order to: (i) characterize the dispersal patterns across the Strait of Bonifacio; (ii) identify the main potential settlement areas; (iii) quantify the connectivity and the larval supply from the MPAs to the surrounding areas. A high resolution hydrodynamic model (MARS 3D, Corse 400m) combined to an individual based model (Ichthyop software) was used to model the larval dispersal of fish...

Autores: Miranda-chumacero, Guido; Mariac, Cédric; Duponchelle, Fabrice; Painter, Lilian; Wallace, Robert; Cochonneau, Gérard; Molina-rodriguez, Jorge; Garcia-davila, Carmen; Renno, Jean-françois.
Identifying fish spawning areas is of great ecological and conservation importance as fishes are suffering increasing threats levels from anthropogenic activities. However, to date very few studies have done so in the Amazon basin. In the Beni River located in the upper Madeira basin, fishers reported that a particular ecotone near Rurrenabaque city was a fish reproduction area. To test the importance of this zone as a spawning site, we conducted an ichthyoplankton survey during the month when reproduction is most likely to occur. The specific identification of larvae and eggs was made with a metabarcoding analysis. With this approach 13 different fish species of high importance for regional and local fisheries were identified, including the long-distance...

On the occurrence of ichthyoplankton in the Saronikos Gulf, Aegean Sea, 1. Anchovy and sardines in 1969-1970-1971.
Provedor de dados: 5
Autores: Yannopoulos, A; Yannopoulosa, C; Soteriades-vlahos, C.
The spawning and nursery grounds of 3 spp of commercial importance, Engraulis encrasicholus, Sardinella aurita and S. pilchardus were studied in the Saronikos Gulf during 1969, 1970 and 1971. The waters of the gulf are very rich due to turbulence caused by currents penetrating the gulf from the Aegean Sea. This turbulence causes bottom upwelling especially in the northern region which is shallower. At the height of their reproduction these fish represent 90-95 per cent of the entire ichthyoplankton, especially in the northern region. E. encrasicholus appears to be the most abundant sp with a maximum of 1099/m super(2) of surface waters (where the density of eggs = 536 and of larvae = 563). 232/m super(2) of surface water represents the maximum for S....

Provedor de dados: 5
Autores: Woehrling, Daniel; Le Fevre-lehoerff, Geneviève.
The sampling of eggs and larvae of sole and sprat at Gravelines (French part of the North Sea coast) since 1975 has produced a long-term series showing major interannual changes, Comparison of the results obtained on two species, one benthic and the other one pelagic, suggests some events affecting the environment that are also revealed by the holoplanktonic (appendicularia, chaetognatha) and meroplanktonic (cirripeda larvae) compartment. This Study attempts also to distinguish general variations from more closely species-related fluctuations.

The eastern English Channel, which connects the Atlantic Ocean to the North Sea through the Dover Strait, is an area where numerous and often conflicting human activities take place. A cross-border multidisciplinary project called CHARM was initiated to provide knowledge and tools for planners and decision-makers to durably manage the shared marine living resources. One such tool was an atlas of fish spatial distributions and modelled habitats, which was used here to investigate ontogenic and seasonal shifts in fish spatial distribution and habitat through a case-study, the dab Limanda limanda. Survey data for several life-history stages (eggs, larvae, coastal nurseries, &lt; and &gt; 1 year old) and seasons were used to map spatial patterns (using...

Autores: Silva,Patrícia Alves da; Reynalte-Tataje,David Augusto; Zaniboni-Filho,Evoy.
This study aims to determine the importance of different environments of the Ligeiro River (upper Uruguay River, Brazil) in fish reproduction. For this purpose, three environments (sampling sites) were selected: rapids, a pool, and the mouth of the Ligeiro River. Ichthyoplankton, zooplankton, and benthos were sampled six times per month from September, 2006 to March, 2007. Zooplankton and ichthyoplankton samples were collected early in the evening with plankton nets (64 µm and 500 µm, respectively). Benthos samples were also collected early in the evening with a Van Veen dredge. Local abiotic variables (temperature, dissolved oxygen, pH, electrical conductivity, water speed, alkalinity, water hardness, and water transparency) were measured simultaneously...

Rhamdia quelen (Jundiá) is a catfish species of great interest to fish producers and researchers due to several favorable characteristics for inclusion in the Brazilian list of commercially raised fish. It has a wide geographical distribution, with occurrences reported from Central Argentina to South Mexico. Studies on the biological aspects of this species have been limited to captive adult fishes that were researched for farming purposes. Research related to ichthyoplankton has provided valuable information on spawning periods and sites and other aspects of breeding for numerous species of fish. This information is crucial for implementing management and protection strategies for these species. The studied floodplain is located in a lotic remnant between...

An analysis was made of the spatial and temporal distribution of the abundance and composition of fish larvae assemblies, aiming to ascertain correlations with biotic and abiotic factors in marginal lagoons of the Cuiabá River floodplain in Brazil's Pantanal wetlands. Samples were collected bimonthly in the pelagic region of the marginal lagoons (fourteen lagoons) close to the littoral zone covered by aquatic macrophytes from December 2006 to April 2007. The captured individuals consisted of 2,739 larvae, represented predominantly by Triportheus spp. (Characidae), Parodontidae, Anostomidae, Characidae and Serrasalmidae. Larval density varied among the sample lagoons in December, but the biotic (zooplankton density) and abiotic (water temperature,...

Researches on ichthyoplankton seems to be an important tool to identification of spawning areas and periods for freshwater fish. Ichthyoplankton was sampled monthly in the headwaters of the Cuiabá River, upper Paraguay River basin, (Mato Grosso State, Brazil), and in four of its tributaries, between November 2007 and March 2008, to evaluate the spatial and temporal distribution of fish eggs and larvae and the influence of regional and local variables on their distribution. In total, 22,067 eggs and 1,045 larvae were collected. A significant negative correlation was found between egg density and the variables of river level and flow volume. Larval density was not significantly correlated with any of the regional variables. The egg and larval densities were...

Autores: Reynalte-Tataje,David A.; Zaniboni-Filho,Evoy; Bialetzki,Andrea; Agostinho,Angelo A.
Natural and induced disturbances greatly influence the temporal distribution of ichthyoplankton abundance. This study assesses and compares the temporal variability of fish larvae assemblages in controlled and free environments to determine the influence of environment variables on the main taxa in these systems. The study was conducted at the Chapecó (without dam impact) and Ligeiro (with dam impact) river mouths, which are located in the upper Uruguay River. Samples were made between October 2001 and March 2004 during three reproductive periods. The larvae assemblages were composed of small and medium-sized Characiformes and Siluriformes. The variation in the distribution of larvae was mainly temporal (&gt;85%). When the three reproductive periods were...

Passage of fish larvae and eggs through the Funil, Itutinga and Camargos Reservoirs on the upper Rio Grande (Minas Gerais, Brazil)
Provedor de dados: 83
Autores: Suzuki,Fábio Mineo; Pires,Lucas Vilela; Pompeu,Paulo Santos.
The objective of this study was to evaluate the passage of fish eggs and larvae through the Funil, Itutinga and Camargos Reservoirs, located in the upper Rio Grande basin, Minas Gerais, Brazil. Samples were taken downstream and upstream of the dams using a conical ichthyoplankton net and were collected every two weeks, twice per sampling day, between November 2008 and March 2009. Although eggs and larvae were abundant immediately upstream of the reservoirs, no ichthyoplankton were captured immediately downstream of the dams, possibly indicating that eggs and larvae do not pass through the reservoirs. The arrival of ichthyoplankton in the reservoirs without its effective passage downstream makes the survival of these eggs and larvae unlikely. Furthermore,...

Autores: Macedo-Soares,Luis C. P.; Birolo,Alesandra B.; Freire,Andrea S.
This study investigated the variation in abundance, distribution and composition of ichthyoplankton in a lagoon in southern Brazil through the year and at different stations within the lagoon. Ibiraquera Lagoon is a shallow coastal lagoon connected to the sea by a semi-permanent sandbar. Ichthyoplankton samples were collected monthly from December 2003 to December 2004, with a 200 µm mesh net using horizontal surface hauls. A colder, drier period was detected, contrasting with warm months during which salinity varied depending on rainfall and whether the sandbar was open or closed. The mean abundance of ichthyoplankton over the study period was 459.6 ± 76.2 (SE) eggs · 100 m-3 and 63.6 ± 7.9 (SE) larvae · 100 m-3, and they were present during all months....

Abstract The influence of salinity and temperature on larval fish assemblages, as well as, temporal and vertical patterns on larval fish assemblages off the inlet of the Presidio River, southeast coast of the Gulf of California were evaluated. Samplings for ichthyoplankton and environmental parameter measurements were carried out at three depths, in five sampling sites, during September and December 1994, and April and June 1995. Anchovies and herrings (Clupeiformes) were the most abundant larval fish accounting for 77% of the total abundance. A significant relationship between salinity and the abundance of larval herrings (Opisthonema medirastre and O. dovii) and between the water temperature and the abundance of the weakfish (Cynoscion reticulatus) was...

It also reports on 11 surveys conducted by INIDEP during 1992-1995. A total of 488 ichthyoplankton samples were analyzed. Fish eggs have been recognized in 47.  of all ichthyoplankton samples. They belong to three species: Coelorhynchus fasciatus, Macrourus whitsoni and Micromesistius australis. Fish larvae of 23 species and 17 families have been identified in 96.  of all samples analyzed. Spawning of most species begins in autumn, and progresses through winter, when the southern blue whiting and grenadier fish contribute to...

Autores: Lett, Christophe; Veitch, Jennifer; Van der Lingen, Carl D.; Hutchings, Larry.
The Lüderitz upwelling cell and Orange River cone (LUCORC) area, a transboundary region between South Africa and Namibia, is considered to be an environmental barrier to transport of ichthyoplankton from the southern to the northern Benguela upwelling ecosystems. We use environmental data and modelling to assess the potential mechanisms responsible for this barrier: environmental data were extracted from the 1 × 1° World Ocean Atlas 2001 database and used to build maps of annual mean salinity, temperature, chlorophyll, dissolved oxygen and nutrient concentrations; outputs of a regional circulation model were used in an individual-based model to assess the transport of passive particles from the southern to the northern Benguela. The data show no clear...

This dissertation is focused on the study of implications of spatial patterns on survival of eggs and larvae and subsequent recruitment of the SW Atlantic anchovy, Engraulis anchoita. The study of distribution patterns is encompassed within the conceptual framework of the analysis of reproductive strategies of marine bony fish, as adaptations that enable them to cope with and actively exploit environmental variability, regulating their abundance and avoiding extinction. The SW Atlantic anchovy, is ideally suitable for studies on reproductive biology and recruitment on a comparative basis. Its spawning and nursery grounds are located in very diverse ecosystems. This variety refers to their physico-chemical properties, carrying capacity, the influence of...

Monthly variability of zooplankton and ichthyoplankton abundance and composition were studied in 6 stations in the Gulf of Tunis between February 2003 and January 2004. Plankton trawls were horizontal, in surface and at night. Study area seems to be influenced by climatic conditions and the outflow of Majreda River that affect the surface temperature and salinity. Copepods, with many abundance peaks in the year, formed the most abundant group (84%) followed by cladocerans (8%) and chaetognaths (3%). The appendicularians, cladocerans and medusae had swarms in the summer, the creseis and the chaetognths in the autun and the zoae larvae in the spring. The highest fish spawning periods was in summer then the highest larva abundance was in winter and...

Autores: Barzotto,Evelyn; Sanches,Paulo Vanderlei; Bialetzki,Andréa; Orvati,Lilian; Gomes,Luiz Carlos.
ABSTRACT Fish larvae and adults are morphologically distinct from each other and have different ecological requirements. Research on the dynamics of ichthyoplankton provides valuable information about the early stages of the life cycle of fish. This study analyzed the temporal and spatial distribution of the larval stages of three migratory species - Salminus brasiliensis (Cuvier, 1816), Prochilodus lineatus (Valenciennes, 1836) and Pseudoplatystoma corruscans (Agassiz, 1829) - to identify possible spawning areas in the last lotic remnant of the upper Paraná River, in the Brazilian territory. A total of 26 points were sampled monthly from October 2003 to November 2004. The PERMANOVA detected significant differences between the months only for S....

Provedor de dados: 104
Autores: Godefroid,Rodrigo Santiago; Hofstaetter,Marion; Spach,Henry Louis.
A total of 6,575 larvae in the preflexion, flexion and post-flexion stages of 15 families, 26 genera and 29 species were captured in the surf zone of Pontal do Sul beach, Paraná, Brazil. Samples of the families Gerreidae and Scianidae predominated and larvae of Eucinostomus argenteus (Baird&amp;Girard, 1854), Micropogonias furnieri (Desmarest, 1823), Eucinostomus gula (Cuvier, 1830), Menticirrhus ameri-canus (Linnaeus, 1758) and Anchoa tricolor (Agassiz, 1829) were the most dominant species. Greater abundance of larvae was observed during the summer, followed by winter and in a less extent during spring and autumn. The number of species was greater in the summer, and there were no significant differences in the rest of the seasons.

Provedor de dados: 42
Autores: SOUZA,CHRISTIANE S. DE; MAFALDA JUNIOR,PAULO O.
Abstract This study investigated the large-scale spatial and temporal variability of larval fish assemblages in the west tropical Atlantic Ocean. The sampling was performed during four expeditions. Identification resulted in 100 taxa (64 families, 19 orders and 17 suborders). During the four periods, 80% of the total larvae taken represented eight characteristics families (Scombridae, Carangidae, Paralepididae, Bothidae, Gonostomatidae, Scaridae, Gobiidae and Myctophidae). Fish larvae showed a rather heterogeneous distribution with density at each station ranging from 0.5 to 2000 larvae per 100m3. A general trend was observed, lower densities at oceanic area and higher densities in the seamounts and islands. A gradient in temperature, salinity,...

Spatio-temporal distribution of fish larvae in relation to ontogeny and water quality in the oligohaline zone of a North Brazilian estuary
Provedor de dados: 49
Autores: Sarpedonti,Valérie; Anunciação,Érica Moema Silva da; Bordalo,Adriana Oliveira.
Larval fish assemblage in Guajará Bay was studied through four quarterly field campaigns and discussed in relation to individuals' development stages and exposure to contaminants poured out by the Pará State Capital City, Belém. Larval densities were low and diversity extremely poor with a strong dominance of clupeids, engraulids and, to a lower extent, sciaenids. The main spawning season was registered at the onset of the rainy period. Pre-flexion and flexion clupeiforms remained in the farmost stations from the city while post-flexion larvae were found near urban activity centres. Unlikely, pre-flexion and flexion sciaenids were scattered along the city waterfront. Post-flexion larvae were rare; it is suggested that sciaenids use the bay as a transitory...

Spatial and temporal variation of fish larvae in a hypersaline bay of the Colombian Caribbean
Provedor de dados: 50
Autores: Gallego Zerrato,Juan José; Giraldo,Alan.
ABSTRACT Spatial distribution patterns and the diversity of organisms are the result of evolution, biogeography and the interaction between the local abiotic and biotic factors that operate at different temporal and spatial scales. This paper describes the spatial and temporal dynamics of the assembly of larval stages of fish in Bahía Portete and evaluates the relationship between spatial and temporal variation in abundance and local oceanographic conditions. Oceanographic and biological information was obtained from two sampling campaigns in July (dry season) and November (rainy season) 2015 to incorporate these contrasting climatic conditions. During each sampling campaign a mesh of 21 stations was performed, distributed in a systematic way in the Bay....

Autores: Beltrán-León,Beatriz Susana; Morales Osorio,Yaneth Alicia.
ABSTRACT With the purpose of characterizing ichthyoplankton in three marine protected areas (Sanquianga National Natural Park, Gorgona National Natural Park and Malpelo Fauna and Flora Sanctuary) in the Colombian Pacific during November 2009, scientific expeditions were carried out to obtain 56 samples by trawling with bongo nets. 3,155 / 10 m2 fish larvae were captured distributed in 1,553 larvae / 10 m2 (49.22 %) for the PNN Sanquianga; 1,411 larvae / 10m2 (44.72 %) for the Gorgona PNN and 191 larvae / 10m2 (6.05 %) for the Malpelo SFF. The main families were Engraulidae (PNN Sanquianga), Bregmacerotidae (PNN Gorgona) and Phosichthyidae (SFF Malpelo). The NMS community analysis shows that the location of the PNN Sanquianga (coastal), PNN Gorgona...

Temporal space-variation of fish larvae in the Gulf of Guayaquil, Ecuador
Provedor de dados: 50
Autores: Calderón-Peralta,Gregoria; Ayora-Macías,Gabriela; Solís-Coello,Pilar.
ABSTRACT This study presents the density, taxonomic composition, spatial and temporal distribution of fish larvae in the Gulf of Guayaquil, as well as the relationship with some physical-chemical variables. Samples were collected at 16 stations, taken in the first nautical mile of the external and internal estuary of the gulf, located in front of the province of Guayas and northwest of the island of Puná, during June to December 2012. Surface trawls were carried out with a simple conical network (mesh eye: 300 μm; mouth diameter: 0.3 m; length: 1.2 m). Temperature, salinity, and transparency were measured before each drag. Significant differences were detected between zones, registering higher temperatures, lower salinity, and transparency in the interior...

Spatial and temporal distribution of ichthyoplankton in the upper Uruguay river, Brazil
Provedor de dados: 52
Autores: Hermes-Silva,Samara; Reynalte-Tataje,David; Zaniboni-Filho,Evoy.
The distribution and abundance of fish eggs and larvae was analyzed in three sections of the Upper Uruguay river, in a stretch of 290 km. Samples were collected monthly from October, 2001 to March, 2002 during 48-h cycles at 6-h intervals between each sampling. Surface and bottom samples were collected with a 0.5-mm mesh cylindroconical net. Fishes from the Upper Uruguay river were reproductively active mainly from October to January, and this activity was more intense at the Ligeiro and Chapecó tributaries and Chapecó main river. It was observed that the tributaries are important spawning grounds and larval nursery sites, indicating the importance of preserving such environments.

Analysis of drift of ichthyoplankton in two channels in the River Paraná, Brazil, were made. Sampling was undertaken from October 1995 to April 1996 during nychthemeral cycles. Water samples were collected to determine several environmental variables. Eggs densities largely differed to layers, times of day and months. In both the channels, highest occurrence of eggs was detected between January and March; greater concentrations at the bottom, during night. With regard to larvae, densities were significantly different in channels, times of days and months. Maximum occurrences were seen in the right channel, in both layers, with largest capture between January and March. Surface of the both channels presented highest density of larvae during night. Water...

Ichthyoplankton distribution and abundance off southeastern and southern Brazil
Provedor de dados: 52
Autores: Freitas,Débora Martins de; Muelbert,José Henrique.
This study describes the distribution of fish eggs and larvae along the southeastern and southern Brazilian coast. Plankton samples were collected at 85 stations using a Bongo net, and water salinity and temperature were profiled with a CTD. Results showed that fish eggs and larvae, and zooplankton biovolume were distributed in coastal waters with mean temperature of 23&amp;#186C and salinity between 33 and 34. The largest egg abundance occurred along Iguape (24&amp;#186'S) with a partial overlap with zooplankton biovolume and fish larvae were most abundant near shore close to Santos (24&amp;#186S). These protected coastal waters presented a surface layer with lower salinity and higher temperatures, while the bottom layer had cooler water. Ichthyoplankton...
