“…The use of grey walls and a diffuse light source is thus appropriate (Hinshaw 1985). Similar results were obtained for European perch where black tank walls resulted in improved body weight and condition factor in comparison to groups reared in tanks with gray walls (Tamazouzt 1995;Jentoft et al 2006). However, results of these experiments are of limited value as all treatments averaged 75 % mortality.…”

For carnivorous species producing relatively small larvae, as Eurasian perch and yellow perch, the successful rearing of early life stages is still a matter of concern, even if significant improvements have been achieved during these last two decades. This chapter presents an overview of the different methods used to produce juveniles of these two species: (i) production of fish in fertilized ponds, with fingerling habituation to artificial feed before or after pond harvest, (ii) fertilization of mesocosms and semi-intensive production up to 45 days old, (iii) intensive production in tanks with supply of live prey progressively replaced by artificial feed. For each system, the optimal husbandry conditions as well as the influence of main factors (stocking density, temperature, growth heterogeneity and management of cannibalism, non-inflation of swim bladder,…) influencing the survival and growth of fish from larval to juvenile stages are described.

“…This is a species from the same basin as curimatá-pioa, and it is a neotropical characiform that swims in the water column. The larvae of Perca fluviatilis reared in black tanks showed an improved Fulton's condition factor compared to the gray tanks (Jentoft et al, 2006), suggesting the response can vary for some species.…”

“…On the other hand, pelagic species have eyes placed laterally (Kirchheim & Goulart, 2010). The contrast between the color of the food organism and the wall of the tank is important for the visual perception of the prey by the larvae (Krise & Meade, 1986;Ostrowsky, 1989), providing higher or lower visibility and consumption of prey (Pedreira & Sipaúba-Tavares, 2001;Strand et al, 2007), and also affecting survival (Tamazouzt et al, 2000;Pedreira et al, 2008b), growth (Jentoft et al, 2006;Strand et al, 2007;Monk et al, 2008), biochemical parameters (Karakatsouli et al, 2007), skin pigmentation (Amiya et al, 2005;Doolan et al, 2007), agonistic behavior and motor activity (Merighe et al, 2004), and finally productivity (Pedreira & Sipaúba-Tavares, 2001). …”

Larviculture of two neotropical species with different distributions in the water column in light- and dark-colored tanks

The influence of tank color on the visual perception of fish larvae and the success of their cultivation depends on the characteristics of each species combined with environmental factors. In this study, we determined the effect of light and dark tank colors on the larviculture of pacamã (Lophiosilurus alexandri), a species with a benthonic habit, and curimatá-pioa (Prochilodus costatus), which swims actively in the water column. Larvae of pacamã and curimatá-pioa were cultivated for 10 days in 5-L tanks, at a density of 15 larvae L -1 and luminosity of 141.7 ± 8.95 lux, and fed Artemia nauplii. Four tank colors were used: green, light blue, brown, and black (with four replications). Survival, biomass and Fulton's condition factor for pacamã larvae were similar in the different colored tanks. However, the larvae in the green tanks showed lower weight than those cultivated in black and brown tanks, as well as shorter total length than that of larvae in the brown-colored tanks. These results are probably due to the association between tank color and benthonic habitat of the pacamã. For the curimatá-pioa, survival and biomass were similar for the different colors. The weight and Fulton's condition factor were higher for the larvae cultivated in green and blue tanks. This result could be associated with the adaptation of curimatá-pioa larvae to active swimming in the water column, searching for prey.A interferência da cor do tanque na percepção visual da larva de peixe e no sucesso do seu cultivo depende da caraterística de cada espécie combinada com fatores ambientais. Neste estudo foi investigado o efeito de tanques de cores claras e escuras na larvicultura do pacamã Lophiosilurus alexandri, espécie de hábito bentônico, e, curimatá-pioa Prochilodus costatus, que nada ativamente na coluna da água. Larvas de pacamã e de curimatá-pioa foram cultivadas por 10 dias, em tanques contendo 5 L de água, a uma densidade de 15 larvas L -1 , luminosidade de 141.7 ± 8.95 lux, alimentados com náuplios de Artemia. Quatro cores de tanques foram usadas: verde e azul claras, marrom e preta (com quatro repetições). Para as larvas de pacamã, a sobrevivência, biomassa e o fator de condição de Fulton foram similares entre os tanques de diferentes cores. Entretanto, as larvas nos tanques verdes apresentara um peso menor do que as cultivadas nos tanques de cor preta e marrom, assim como um menor comprimento total, que as larvas cultivadas em tanque marrom. Estes resultados provavelmente têm origem da associação da cor do tanque com o hábito bentônico do pacamã. Para o curimatá-pioa, a sobrevivência e a biomassa foram similares entre as cores. O peso e o fator de condição de Fulton foram maiores para as larvas cultivadas nos tanques de cor verde e azul, seguidas pelo marrom e preto. Este resultado pode estar associado a adaptação das larvas de curimatá-pioa a natação ativa na coluna da água à procura de presa.

“…Para outras espécies, a cor do tanque também afeta a sobrevivência (Tamazouzt et al, 2000), o crescimento (Jentoft et al, 2006;Strand et al, 2007), parâmetros bioquímicos (Karakatsouli et al, 2007), pigmentação da pele (Amiya et al, 2005;Doolan et al, 2007), comportamento agonístico e atividade motora (Merighe et al, 2004). Além disso, a coloração do tanque pode levar a um maior contraste do alimento, o que facilita sua captura com conseqüente melhora na produtividade (Pedreira & Sipaúba-Tavares, 2001).…”

Resumo -O objetivo deste trabalho foi avaliar o efeito de diferentes cores de tanques na larvicultura de Brycon orthotaenia, durante os primeiros dez dias de criação. Foram avaliados tanques de cores claras (branco, azul claro e verde claro) e escuras (marrom e preto). Como alimento, utilizaram-se larvas de Prochilodus costatus, até o quinto dia de alimentação, e a partir do terceiro dia foi também fornecida ração comercial com 55% de proteína bruta. Foram analisados: o crescimento, a sobrevivência e o fator de condição de Fulton. Aos cinco dias, tanto o peso como o comprimento total e a taxa de crescimento específi co (TCE) foram semelhantes entre os tratamentos. No entanto, aos dez dias, animais mantidos em tanques de cores escuras apresentaram menor peso e comprimento total, porém, com TCE semelhante apesar das diferentes cores de tanque. O fator de condição de Fulton, ao fi nal do experimento, foi menor nos animais mantidos em tanques escuros. A sobrevivência foi menor em tanques de cor preta, aos cinco e dez dias de criação. Os maiores valores foram registrados nos tanques de cores marrom, verde claro e branco. Tanques claros são recomendados para a larvicultura de B. orthotaenia, pelo melhor desempenho e sobrevivência dos animais.Termos para indexação: Brycon orthotaenia, alimentação, canibalismo, manejo. Matrinxã larviculture in tanks of different colorsAbstract -The objective of this work was to evaluate the effect of different color tanks on Brycon orthotaenia larviculture, during the fi rst ten days of rearing. Light color tanks (white, light blue and light green) and dark tanks (brown and black) were evaluated. The fi shes were fed with Prochilodus costatus larvae until the 5 th day and, from the 3 rd day on, commercial dry feed with 55% crude protein was also supplied. The growth, survival and Fulton's condition factor were evaluated. At fi ve days of feed, the weight, total length and specifi c growth rate (SGR) were similar among treatments. However, after ten days, the animals kept in dark tanks showed the lowest weight and total length; but the SGR was similar despite the different color tanks. The Fulton's condition factor, observed at the end of the experiment, was lower in animals reared in dark tanks. The survival was lower in black tanks, at fi ve and ten days of rearing. The best survival, at the end of the experiment, was observed in brown, light green and white tanks. Light tanks are recommended for B. orthotaenia larviculture, for animals' best development and survival.
