Differential survivorship of congeneric ornamental fishes under forecasted climate changes are related to anaerobic potential
Provedor de dados: 74
Autores: Gonçalves,Luciana Mara Fé; Silva,Maria de Nazaré Paula da; Val,Adalberto Luis; Almeida-Val,Vera Maria Fonseca de.
Abstract Two Amazonian closely related tetras – cardinal Paracheirodon axelrodi and green neon P. simulans – were artificially acclimatized to environmental chambers mimicking future climate change scenarios (mild, moderate and extreme), using a microcosm facility. P. simulans survived (100%) to all scenarios after 30 days exposure, while P. axelrodi presented decreasing survival percentages according to environmental severity. These differences may be the reflection of distinct natural acclimatization to microhabitats between the species, which differ in thermal conditions. Survival responses might be related to differences in relative gene expression of lactate dehydrogenase (Ldh), suggesting that P. axelrodi anaerobic potential is lower or non-existent...

Morphological variation among populations of Hemigrammus coeruleus (Characiformes: Characidae) in a Negro River tributary, Brazilian Amazon
Provedor de dados: 83
Autores: Lazzarotto,Henrique; Barros,Thiago; Louvise,José; Caramaschi,Érica Pellegrini.
ABSTRACT We explored patterns of phenotypic variation in Hemigrammus coeruleus from the Unini River basin, a blackwater river in the Brazilian Amazon. Geometric morphometrics was used to evaluate variation in body shape among populations from four tributaries (UN2-UN5). We found no evidence for sexual dimorphism in body size and shape. However, morphological differences among populations were detected as the analyses recovered significant groups corresponding to each sub-basin, with some overlap among them. The populations from UN2, UN3 and UN5 had more elongate bodies than fish from UN4. The most morphologically divergent population belonged to UN4, the tributary with the most divergent environmental conditions and the only one with seasonally-muddy...

Reproductive and population parameters of discus fish Symphysodon aequifasciatus Pellegrin, 1904 (Perciformes: Cichlidae) from Piagaçu-Purus Sustainable Development Reserve (RDS-PP), lower Purus River, Amazonas, Brazil
Provedor de dados: 83
Autores: Rossoni,Felipe; Amadio,Sidinéia; Ferreira,Efrem; Zuanon,Jansen.
The ornamental discus fish Symphysodon aequifasciatus Pellegrin, 1904, is a popular endemic cichlid species from the Amazon basin, however scientific information concerning biology and ecology in its natural habitat is scarce despite its importance on the international aquarium trade. In this study we evaluated reproductive parameters of S. aequifasciatus in natural habitat in Piagaçu-Purus Sustainable Development Reserve (RDS-PP), lower Purus River, Brazilian Amazon. Males are more frequent in the larger size classes and this might be related to the complex breeding behavior known for S. aequifasciatus. Values of L50 for both sexes corresponded to more than 60% of the maximum attained length which may indicate that energy allocation for somatic growth...

Glyphosate commercial formulation effects on preoptic area and hypothalamus of Cardinal Neon Paracheirodon axelrodi (Characiformes: Characidae)
Provedor de dados: 83
Autores: Riaño-Quintero,Camilo; Gómez-Ramírez,Edwin; Hurtado-Giraldo,Hernán.
ABSTRACT In Colombia the use of glyphosate commercial formulations (Roundup™) for spraying have left deleterious effects on animals and humans. Much of this spraying takes place at the Orinoco basin, habitat of one of the most exported ornamental fish in Colombia, Cardinal neon. To evaluate the effect of Roundup Activo™ four experimental treatments were carried out with 0 mg/L (T1), 0.1 mg/L (T2), 1 mg/L (T3) and 5 mg/L (T4) during 30 days of exposure. The fishes were processed for high-resolution optical microscopy. The main finding of Roundup Activo™ exposure was an increase in mast cells number in brain blood vessels and some neuronal nuclei of the preoptic and posterior diencephalic areas, including hypothalamus. A correlation between concentrations...

Morphological and immunohistochemical comparison of the pituitary gland between a tropical Paracheirodon axelrodi and a subtropical Aphyocharax anisitsi characids (Characiformes: Characidae)
Provedor de dados: 83
Autores: Camacho,Laura Rincón; Pozzi,Andrea G.; de Freitas,Eliane G.; Shimizu,Akio; Pandolfi,Matías.
ABSTRACT Cardinal tetra Paracheirodon axelrodi and bloodfin tetra Aphyocharax anisitsi are two species of characids with high trade value as ornamental fish in South America. Although both species inhabit middle water layers, cardinal neon exhibits a tropical distribution and bloodfin tetra a subtropical one. Generally, these species are difficult to grow, so it becomes essential to know some key components of the neuroendocrine system to achieve their reproduction in captivity. Considering the importance of deepening the knowledge of the reproductive physiology through functional morphology, for the first time in this work we performed an anatomical, morphological and immunohistochemical analysis of the pituitary gland of these two species. In both...

Effect of beta 1,3 glucan in stress responses of the pencilfish (Nannostomus trifasciatus) during transport within the rio Negro basin
Provedor de dados: 83
Autores: Abreu,Janessa S.; Brinn,Richard P.; Gomes,Levy C.; McComb,Dawn Michelle; Baldisserotto,Bernardo; Zaiden,Sérgio F.; Urbinati,Elisabeth C.; Marcon,Jaydione L.
We investigated the use of beta 1,3 glucan as an imunostimulant during a transport experiment to determine the effects upon the stress response of the pencilfish (Nannostomus trifasciatus). Pencilfish were fed for seven days with different concentrations of beta 1,3 glucan: 0.0% (control); 0.01%; 0.1% and 0.5% of beta 1,3 glucan per kg of feed-1. Fish were then transported for 24 hours by boat from Barcelos to Manaus. The highest dose of beta 1,3 glucan in the food increased Na+influx after 12 hours of transport and 0.1 and 0.5% beta 1,3 glucan maintained the flux of both ions close to zero at 24 hours. All doses of beta 1,3 glucan reduced K+ loss significantly in the beginning of the transport, but after 12 to 24 hours did not. No significant differences...

Autores: Pereira, M.A.M.; Whittington, M.; Gonçalves, M.; Costa, A.
The extensive coral reefs along the coastline of Mozambique are a valuable national resource. They provide food and income for a large proportion of the country’s coastal communities and have a great potential for generating substantial economic growth within the tourism sector. The government of Mozambique has recognised the importance of coral reefs and has initiated a number of actions aimed at the sustainable management and conservation of this resource under its National Coral Reef Management Programme (NCRMP). The current two year moratorium on the trade in ornamental fish and live corals is one such initiative and it was important that the opportunity to formulate a framework for the sustainable management of this trade be acted upon quickly. It is...

Possible applications of modern fish larviculture technology to ornamental fish production
Provedor de dados: 27
Autores: Dhert, P.; Lim, L.C.; Candreva, P.; Van Duffel, H.; Sorgeloos, P.
There has been rapid development in the marine foodfish larviculture technology in Europe since the early eighties, especially in the flat fish, turbot and halibut, and the bass and bream species. The most significant improvements in the eighties were the introduction of light control, artificial reproduction techniques, appropriate water treatment and the use of rotifers and &lt;i&gt;Artemia&lt;/i&gt; nauplii of specific sizes and in the late eighties and early nineties the quality enhancement of live food organisms using specific enrichment techniques. Present research is focused on the implementation of several microbial techniques to improve the hygiene of live prey and fish. Many of the modern larviculture techniques being used in marine foodfish...

Provedor de dados: 96
Autores: Paixão,Daércio José de Macedo Ribeiro; Brabo,Marcos Ferreira; Soares,Lourdes Marília Oliveira; Campelo,Daniel Abreu Vasconcelos; Veras,Galileu Crovatto.
ABSTRACT The influence of feeding frequency on growth performance, batch uniformity, and survival rate of severum (Heros severus) larvae and juveniles was investigated in two experiments. In the first, 200 five-day-old severum larvae with 3.20±0.31 mg and 6.20±0.39 mm were randomly distributed into 20 aquaria (1 L) and fed 500 Artemia nauplii larvae−1 day−1 for 15 days. In the second, 120 severum juveniles, 178.19±33.59 mg and 1.82±0.09 cm, were randomly distributed into 15 aquaria (300 L) and hand-fed a commercial diet (400.0 g kg−1 crude protein and 21.2 kJ g−1 gross energy) until apparent satiety for 30 days. For both experiments, feeding frequencies of one, two, three, four, and five meals day−1 were evaluated. We used four replicates for the first...

ABSTRACT The objective of this study was to describe the growth of freshwater angelfish (Pterophyllum scalare) using the Gompertz model, determining the relative growth and allometric coefficients of body components in relation to body weight and protein weight. Six hundred animals were grown until 233 days of age. Data on chemical composition (water, lipid, protein, and ash) and weight measurements were obtained each 30 days. The Gompertz growth equation was used to analyze chemical allometry and to estimate growth parameters. The relationship between chemical components and body protein was estimated. Protein and body weight increased proportionally, with ash being the earliest nutrient (209.2 days), while lipid deposition occurred later. Linear...

Provedor de dados: 96
Autores: Giannecchini,Luiz Gustavo; Massago,Haluko; Fernandes,João Batista Kochenborger.
This study investigated the effect of different photoperiods (24 h of light (L):0 h of darkness (D); 20L:4D; 16L:8D; 12L:12D; and 8L:16D) on the reproduction and growth of Betta splendens. The results showed that spawning frequency was significantly higher in couples reared under 16L:8D and 12L:12D, in comparison with other treatments. The highest number of eggs per spawn was obtained under 16L:8D (544.76±375.23) and 12L:12D (471.13±261.52), and the lowest values were detected for 24L:0D (128.55±58.14) and 20L:4D (187.87±103.84). Fertility and fecundity also showed significantly higher average values in 16L:8D and 12L:12D when compared with 24L:0D and 20L:4D treatments. Egg volume and perivitelline space were significantly higher in 24L:0D treatments that...

Autores: Nascimento,Lidiane da Silva; Reis,Sendy Moreira; Ferreira,Pollyanna de Moraes França; Kanashiro,Márcio Yoshiyuki; Salaro,Ana Lúcia; Zuanon,Jener Alexandre Sampaio.
ABSTRACT We aimed to evaluate the effects of Curcuma longa as growth promoter, skin pigmentation enhancer, and stress reducer in diets of Trichogaster labiosa after transport. We used five diets containing 0.0, 1.0, 5.0, 10.0, and 25.0 g kg−1 of turmeric rhizome powder. We observed quadratic effects of turmeric supplementation for feed intake, weight gain, final length, and specific growth rate. The estimated amount of turmeric that decreased these variables ranged from 15.53 to 16.39 g kg−1. Quadratic effects of supplementation of turmeric for cyan and black dorsal skin coloring indices were observed, with estimated values that increased these variables equal to 15.03 and 17.44 g kg−1, respectively. After fish transport, quadratic effects of turmeric were...

Feeding level and frequency for freshwater angelfish
Provedor de dados: 96
Autores: Ribeiro,Felipe de Azevedo Silva; Vasquez,Leonardo Avendaño; Fernandes,João Batista Kochenborger; Sakomura,Nilva Kazue.
The objective of this study was to determine the optimal feeding level and feeding frequency for the culture of freshwater angelfish (Pterophyllum scalare). A randomized block design in a factorial scheme (3 × 2) with three feeding levels (30, 60 and 90 g/kg of body weight (BW)/day) and two feeding frequencies (1x and 2x/day) was set up in duplicate, representing 24 experimental units. Data were analyzed using two-way ANOVA and the Tukey test for comparison between means. After 84 days, results indicated that both factors influenced fish performance. No interaction between these factors was, however, observed. Increased feeding level and feeding frequency resulted in increased feed intake. The feed conversion ratio was negatively affected by feeding level,...

Provedor de dados: 36
Autores: COSTA,Igor David da; SOARES,Maiza Oliveira.
Trophic relationships in fish communities are affected by the availability of resources, which in turn is affected by spatial and temporal variations throughout the year. The aims of this study were to characterize the diet of A. tetramerus in a streamlet in the north of Brazil and compare its composition in different hydrological seasons (wet and dry seasons). Collections were performed every two months from October 2011 to September 2012 with the aid of seine nets, hand net and fishing traps in the streamlet located in the Machado River drainage basin in the Rondônia state. Most of the specimens collected were quite small (&lt; 40 mm) and had empty stomachs. Our results showed that A. tetramerus feeds on a wide variety of items of plant origin, such as...

Poor water quality condition has been pointed out as one of the major causes for the high mortality of ornamental fishes exported from the state of Amazonas, Brazil. The purpose of the current study was to define water quality standards for cardinal tetra (Paracheirodon axelrodi), by establishing the lower and higher for lethal temperature (LT50), lethal concentration (LC50) for total ammonia and nitrite and LC50 for acid and alkaline pH. According to the findings, cardinal tetra is rather tolerant to high temperature (33.3 ºC), to a wide pH range (acid pH=2.9 and alkaline pH=8.8) and to high total ammonia concentration (23.7 mg/L). However, temperatures below 19.6 ºC and nitrite concentrations above 1.1 mg/L NO2- may compromise fish survival especially...

Autores: COSTA,Igor David da; ROCHA,Vanessa Martins da.
ABSTRACT Studies on the trophic structure of fish give information on species autoecology and their role in the ecosystem. The aims of this study were to characterize the diet of Serrapinnus notomelas in small streams of the River Machado basin and to assess the effect of rainfall seasonality. Fish were collected bimonthly from July 2013 to May 2014 with seine nets and hand nets. The length of each specimen was measured to identify category classes. There were also measured the fullness index and volume of each ingested item, and these data were combined to obtain an alimentary index. We used ANOVA and Kruskal-Wallis to test for differences between length classes and fullness index, Chi-squared tests to detect seasonal differences in origin of food items...

Provedor de dados: 3
Autores: Morey, Germán Augusto Murrieta.
Corydoras splendens (Castelnau, 1855) and Brochis multiradiatus (Orcés V., 1960) are highly demanded for exporters in the Peruvian Amazon and importers all over the world.  The exportation of this fish species may represent a gateway for endoparasites to enter in a new environment with serious effects, so, the present study reports the presence of Tylodelphys sp. infecting C. splendens and B. multiradiatus. Fish were acquired from fishermen of the city of Iquitos, Peru. After the necropsy and analyses of the fish, metacercariae of Tylodelphys sp. were found in the liver and intestine. This finding represents the first report of Tylodelphys Diesing, 1850 infecting a fish in the Peruvian Amazon. Considering the possible damages caused by species of...
