Mercury content in commercial pelagic fish and its risk assessment in the Western Indian Ocean
Provedor de dados: 5
Autores: Kojadinovic, Jessica; Potier, M; Le Corre, M; Cosson, R; Bustamante, Paco.
As top predators of pelagic food webs, large fish naturally bioaccumulate mercury (Hg). Determining Hg burdens in commercialized fish is essential considering the concern about effects of contaminants on human health and the legal thresholds that are therefore set for local consumption and/or exportation. Total Hg levels were measured in the muscular tissue of 183 fish of five commercially important species from the tropical zone of the Western Indian Ocean. All individuals were measured and sexed in order to study the impregnation of Hg with size and sex within each species. Values of Hg found in this part of the Indian Ocean were comparable to Hg in muscular tissue of the same species studied in other areas. The highest Hg levels were noted in Swordfish...

Fish aggregation device (FAD) research: gaps in current knowledge and future directions for ecological studies
Provedor de dados: 5
Autores: Dempster, Tim; Taquet, Marc.
We reviewed the literature concerning fish aggregation devices (FADs) to determine areas of relative research deficiency. Using specific searches of the Aquatic Sciences and Fisheries Abstracts ( ASFA) database from 1978 to December 2003 and a classical search of the pre-1978 literature, we collected 407 references on FADs. Publications before 1980 were predominantly peer-reviewed, although non-peer reviewed literature has dominated since 1980, due to the numerous technical reports produced as FADs became more widely used in artisinal and large-scale industrial. sheries in the 1980s. Most studies of the ecology of FAD-associated fish were descriptive, with few mensurative experimental studies and even fewer manipulative experimental studies that tested...

Satellite-linked acoustic receivers to observe behavior of fish in remote areas
Provedor de dados: 5
Autores: Dagorn, L; Pincock, D; Girard, C; Holland, K; Taquet, Marc; Sancho, G; Itano, D; Aumeeruddy, R.
Automated acoustic receivers are now widely used by biologists to study the behavior of fish. However, currently available acoustic receivers require physical recovery of the units to download stored data. Such operation is often difficult in remote study areas like in the open ocean. We present a new satellite-linked acoustic receiver (Vemco VR3-Argos) that allows downloading data through a satellite uplink (Argos). The VR3-Argos can last up to one year, sending GPS positions and tag data at regular time intervals. We illustrate the advantages of this new technology with tagging data from 121 fish of seven species (yellowfin tuna, bigeye tuna, skipjack tuna, wahoo, dolphinfish, silky shark and oceanic triggerfish) caught and released around drifting fish...

Aggregative capacity of experimental anchored Fish Aggregating Devices (aFADs) in Northeastern Brazil revealed through electronic tagging data
Provedor de dados: 5
Autores: Véras, Luísa Queiroz; Capello, Manuela; Forget, Fabien; Tolotti, Mariana Travassos; Véras, Drausio Pinheiro; Dagorn, Laurent; Hazin, Fábio Hissa.
Catches of pelagic fish associated to anchored Fish Aggregating Devices have been responsible for increases in income, fish consumption, and even cultural identity of artisanal fishing communities in many developing countries worldwide. Nonetheless, in Brazil, aFAD fishing is still poorly developed and studied. In this experiment, FADs were anchored offshore the city of Recife (Northeastern Brazil) to investigate the potential of moored buoys in the aggregation of commercially important pelagic species near the coast, as an alternative fishing site for artisanal fishers. The behavior of acoustically tagged fish was investigated to assess whether they were attracted to the FADs and how long they remained associated to them. The results indicated that,...

Overview of recent progress in fisheries acoustics made by Ifremer with examples from the Bay of Biscay
Provedor de dados: 5
Autores: Trenkel, Verena; Berger, Laurent; Bourguignon, Sebastien; Doray, Mathieu; Fablet, Ronan; Masse, Jacques; Mazauric, Valerie; Poncelet, Cyrille; Quemener, Gael; Scalabrin, Carla; Villalobos, Hector.
This paper provides an overview of the progress Ifremer has made recently in fisheries acoustics and the study of small pelagic fish by: i) pushing observation frontiers using a range of platforms including an autonomous underwater vehicle, AUV, ii) developing measuring instruments and methods and iii) studying fish distributions. Presently, information from several frequencies of single-beam echosounders is routinely collected together with data from the ME70 multibeam echosounder. For onboard data acquisition control the HERMES software was developed. The new MOVIES 3D software includes modules for simultaneous realistic 3D visualisation and post-processing such as bottom detection, school extraction and calculation of descriptors and integration of all...

Acoustic detection of the spatial and temporal distribution of fish shoals in the Bay of Biscay
Provedor de dados: 5
Autores: Scalabrin, Carla; Masse, Jacques.
Echo sounder data were used to investigate the spatio-temporal variability of shoal behaviour in the Bay of Biscay. Data collected from annual surveys were processed using MOVIES-B software in order to mcasure this variability. The software was designed to measure morphological, energetic and space-time distribution descriptors from the acoustic signal received from fish shoals. Two surveys, DAAG 90 and DAAG 91, provided the appropriate characteristics for such an analysis. The survey's objective was to obtain relative abundance indices for the anchovy (Engraulis encrasicolus) biomass in the Bay of Biscay. The surveys were carried out in the same area (southern Bay of Biscay), at the same period (April) within one year interval (1990 and 1991), using the...

Mise en évidence et suivi de l'oxydation des lipides au cours de la conservation et de la transformation du chinchard (Trachurus trachurus) : choix des procédés
Provedor de dados: 5
Autores: Eymard, Sylvie.
Critical steps of the process of horse mackerel surimi manufacturing were identified. This led to propose technical and chemical solutions in order to limit development of lipid oxidation reactions. In this way, analytical methods of lipids and lipid oxidation compounds were adapted to the studied products. A method to determine hydroperoxyde concentrations was developed. The front face fluorescence technique was tested to evaluate the degree of surimi alteration. Lipid oxidation kinetics were determined during horse mackerel storage on ice or at 17°C. The formation of lipid oxidation products was followed during manufacturing and horse mackerel surimi frozen storage. The impact of raw material freshness on the development of lipid oxidation during surimi...

Association dynamics of tuna and purse seine bycatch species with drifting fish aggregating devices (FADs) in the tropical eastern Atlantic Ocean
Provedor de dados: 5
Autores: Tolotti, Mariana Travassos; Forget, Fabien; Capello, Manuela; Filmalter, John David; Hutchinson, Melanie; Itano, David; Holland, Kim; Dagorn, Laurent.
Several pelagic fish species are known to regularly associate with floating objects in the open ocean, including commercially valuable species. The tuna purse seine industry takes advantage of this associative behavior and has been increasingly deploying free-drifting man-made floating objects, also known as fish aggregating devices (FADs). Using passive acoustic telemetry, this study describes the associative dynamics of the main targeted tropical tuna species (Thunnus albacares, T. obesus and Katsuwonus pelamis), as well as three major bycatch species, silky shark (Carcharhinus falciformis), rainbow runner (Elagatis bipinnulata) and oceanic triggerfish (Canthidermis maculata). Short-term excursions away from the FADs were frequently performed by all tuna...

Spatial distribution of pelagic fish off Adelie and George V Land, East Antarctica in the austral summer 2008
Provedor de dados: 5
Autores: Moteki, Masato; Koubbi, Philippe; Pruvost, Patrice; Tavernier, Eric; Hulley, Percy-alexander.
Pelagic fish assemblages and community structure were examined along longitudinal and meridian transects off Adelie and George V Land, East Antarctica, in the austral summer 2008. Fish were sampled with an RMT 8 net principally from six discrete depth layers (0-50-100-200-500-100-2000 m) in the oceanic zone and from three depth layers (0-50-100-200 m) over the continental shelf zone. A total of 20,281 individuals from 27 species were collected. Pleuragramma antarcticum was the most dominant species by number (18,710 inds), followed by Chionodraco hamatus (768), Trematomus newnesi (375), Cyclothone microdon (101), Electrona antarctica (92), Bathylagus antarcticus (51) and Notolepis coatsi (54).

Interaction between fish and fishing vessels in the Javanese purse seine fishery
Provedor de dados: 5
Autores: Potier, Michel; Petitgas, Pierre; Petit, Didier.
The purse-seiners of the Java Sea use light and fish aggregating devices (FAD) to concentrate and catch small pelagic fish (Decapterus sp., Amblygaster sirm, Sardinella gibbosa). This sets a question about the interaction between fish and fishing vessels. Relevant estimates of fishing mortality and fishing effort require an understanding of this interaction. To gain information on this relationship, acoustic surveys were performed on the fishing grounds and the present paper analyses these data. Using acoustic surveys, the fish density was measured and the number of schools was counted per sea surface unit. The fishing vessels were located by radar. Acoustic data were stratified into two groups, one where fishing vessels were present and the other where...

Trophic ecology of European sardine Sardina pilchardus and European anchovy Engraulis encrasicolus in the Bay of Biscay (north-east Atlantic) inferred from delta C-13 and delta N-15 values of fish and identified mesozooplanktonic organisms
Provedor de dados: 5
Autores: Chouvelon, Tiphaine; Chappuis, A.; Bustamante, Paco; Lefebvre, Sebastien; Mornet, Francoise; Guillou, G.; Violamer, L.; Dupuy, Christine.
European sardine (Sardina pilchardus) and European anchovy (Engraulis encrasicolus) are two species of economical and ecological significance in the Bay of Biscay (north-east Atlantic). However, the trophic ecology of both species is still poorly known in the area, and more generally, few studies have considered the potential trophic overlap between sardines and anchovies worldwide. This study aims to highlight the trophic links between the mesozooplankton and adults of these two pelagic fish in the Bay of Biscay, through carbon and nitrogen stable isotope analysis (SIA). Mesozooplankton and individuals of sardines and anchovies were collected during one season (spring 2010), over spatially contrasted stations within the study area. First, the potential...

A method for reducing uncertainty in estimates of fish-school frequency response using data from multifrequency and multibeam echosounders
Provedor de dados: 5
Autores: Berger, Laurent; Poncelet, Cyrille; Trenkel, Verena.
Fish schools can be insonified simultaneously with multifrequency echosounders (e.g. Simrad EK60s) and a multibeam echosounder (e.g. Simrad ME70). This paper presents a method for combining these data to improve estimates of the relative frequency response r(f) of fish schools. Values of r(f) are now commonly used to classify echoes in fishery surveys. The data from the roll- and pitch-stabilized, high-resolution ME70 are used to correct beam-width effects in the multifrequency EK60 data. First, knowing the exact position and orientation of the transducers and the position of the vessel, the echoes are placed into a common geographic coordinate system. Then, the EK60 data are rejected if they do not include a significant percentage of the fish school...

Survey of the Demersal Fish Resources of the outer shelf and slope off Ghana
Provedor de dados: 20
This survey focused on the outer shelf and deep water slope off Ghana and the catch-distribution analyses were therefore performed for four depth strata, outer shelf (&lt; 100 m), upper slope (100-300 m) mid slope (300-600 m) and lower slope (&gt;600 m). In the analyses the “Demersal” group includes commercially important families as Sciaenidae, Haemulidae (=Pomadasyidae), Serranidae, Sparidae and Lutjanidae, and especially in deeper waters the Merluccidae, Macrouridae and Moridae. The Pelagic group includes Engraulidae, Clupeidae, Carangidae, Scombridae, Sphyraenidae, Gempylidae and Trichiuridae (the latter family is actually mainly benthopelagic). For the analysis the “other” group includes all species not accounted for in the groups listed.

Résumé : En 1990, la pêcherie pélagique en Mauritanie s’est caractérisée par d’importantes variations – tant en termes d’effort et de rendement qu’au niveau de la composition spécifique des captures – par rapport aux années antérieures. En effet, l’effort, exprimé en jours de pêche standards, a atteint 9761 jours de pêche standards ; ce qui constitue une augmentation de plus de 21% par rapport à 1989. Aussi, avec 372000 tonnes, les captures totales ont enregistré une augmentation de 4,4%. Pour sa part, la Prise par Unité d’Effort (PUE) a enregistré un recul sensible passant de 44 tonnes/jour de pêche (t/jp) en 1989 à 38 t/jp en 1990. La composition spécifique des captures a été marquée par une augmentation importante de la contribution des sardinelles qui...

Environmental influence on marine pelagic fish: Evidence from bioeconomic modelling
Provedor de dados: 20
Autores: Agbesi, E.N.
Environmental factors other than fishing effort, contribute to influencing marine pelagic fish population dynamics and abundance. There is evidence from environmental modelling and bioeconomic analysis of the Ghanaian marine inshore pelagic fisheries. Ghana is a West African country and lies on the Greenwich Meridian. It is bordered at the South by the Gulf of Guinea. The official language of Ghana is English, but is surrounded by French speaking countries. The inshore fishery is a multi-specie, multi-fleet fishery, consisting of artisanal and inshore purse seine fleets. The coastal inhabitants depend mainly on the marine fisheries as source of employment and livelihood. Fisheries constitute 5% of Agriculture GDP. The two fisheries types in the inshore...

Case Study Of Small Pelagic Fish Resources In Northwest Africa
Provedor de dados: 20
Autores: Samb, B.
The marine waters off Northwest Africa are very productive because of the active upwelling that takes place at different intensities along the coast and which supports important fish resources (among which the small pelagics are the most abundant). The fishery sector plays an important role in the economies of the different countries of the region. Despite their relatively low commercial value, the pelagic fish are dominating the catches and is important to both the industrial and artisanal sectors. Several assessment studies of these resources have been carried out,and the management recommendations given calls for a control of effort in the mackerel and horsemackerel fisheries, whereas a catch level not to be exceeded has been defined for sardinella.

The daily spawning females fraction (S) of Argentine anchovy (Engraulis anchoita) in relation to the year, length, proportion of females, temperature and salinity variables was studied using generalized linear models. Samples were collected during eleven research surveys carried out in the main spawning seasons and areas during 1993-2008 (Southwest Atlantic Ocean, Argentine Sea). The aim of this work was to identify the factors that affect the spawning activity. No temporary differences were observed and an S 0.12 average value was estimated. The poor explanatory percentage of the models analyzed did not allow to clearly detect the variables that could affect S. Length and temperature were the only variables that related positively, which suggests that...

Innovation in commercialization of pelagic fish: the example of "Srdela Snack" Franchise
Provedor de dados: 31
Autores: Kolega,   Ante; Radman,   Marija; Markovina,   Jerko.
The consumption of fish in Croatia is relatively low for a Mediterranean country. One of the main reasons for this is the inadequate supply of fish. The supply of fish is usually limited to expensive species of whitefish, while the supply of pelagic fish is very scarce. Pelagic fish can rarely be found in restaurants, and in the fish- markets it reaches very high prices. The basic goal of the project "Srdela Snack" (srdela - Croatian word for sardine) was to set up and test a new model of commercialization of pelagic fish through franchise "fast - food" outlets. In the paper we will describe the concept of this new model which includes the whole distribution channel, from fishermen, through processors, restaurants to consumers. In this model fishermen...
