“…It is possible that better results with pacamã larvae in brown tanks, followed by black, blue and green, are also associated with animal welfare. This may be one of the research lines to follow, as suggested by Peña et al (2004), who reported on the perception capacity of fish larvae and their development of physiological responses. Volpato & Barreto (2001) observed that rearing in green and white light increased cortisol levels in Nile tilapia (Oreochromis mossambicus) adults, but there was no effect when these fish were maintained under blue light.…”

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.

“…Unlike other teleost species, the endogenous feeding period of the spotted sand bass larvae Paralabrax maculatofasciatus (Steindachner) is relatively short, lasting 2 days at 25° C (Peña et al ., 2003). During this time, the eyes become pigmented and the mouth and anus open for food ingestion and egestion (Peña et al ., 2004). Although survival during larval rearing of the spotted sand bass has improved in recent years (Alvarez‐González et al ., 2001), high mortality rates have occurred during the first‐feeding phase.…”

The impact of delayed feeding early in development on late feeding ability and development of spotted sand bass Paralabrax maculatofasciatus larvae was examined. Larvae were sampled from hatching until day 19 after delayed feeding for zero (control), 1, 2, or 3 days. Feeding incidence was evaluated as the percentage of larvae with food in the gut and feeding intensity was measured by direct counting of prey after dissection of the gut. Delayed feeding effects due to starvation were observed early in development. By day 5, significant differences (P < 0Á05) were observed between controls and larvae submitted to degrees of delayed feeding, including total length (L T ), eye diameter, and the size of the head, liver, gut, muscles and body. Differences were still apparent in L T , and body, liver and muscle heights at the end of the studied period. Larvae under total starvation did not survive beyond day 5. Initial feeding incidence was 35, 60, 90 and 10% for larvae first fed on day 2, 3, 4 or 5, respectively. Mean AE S.D. feeding intensity was 3Á6 AE 0Á8, 2Á8 AE 1Á3, 5Á2 AE 0Á3, and 10Á2 AE 1Á5 rotifers per larva depending on whether larvae were initially fed on day 2, 3, 4 or 5, respectively. The point of no return occurred between 4 and 5 days after hatching. # 2005 The Fisheries Society of the British Isles

“…Diet habits can form gradually with learned experience; therefore, most cultivated teleost fishes can learn to accept artificial diets without difficulty (Brown, 1985;Warburton, 2003). In addition, although the environmental factor is a major component of behavioral changes with learned experience, the impact of the genetic factor must also be considered Carvalho et al, 2004;Jackson et al, 2004;Peňa et al, 2004;Snickars et al, 2004;Stoner, 2004;Carton, 2005;Hara, 2006;Liang et al, 2008). In contrast with learning experience, unlearned genetic predispositions should be extremely important to the formation of the species-specific food habits of different fishes, as well as individual variations in food intake and utilization from first feeding (Liang et al, 2011).…”

ABSTRACT. It is very important to investigate the reasons for the large individual differences in individual performance of food acceptance when using formulated diets for the successful culture of larvae and juveniles of the Chinese sturgeon Acipenser sinensis. Genetic differences of the mitochondrial control region were investigated by direct sequencing in two groups of Chinese sturgeon, which were apt to accept or refuse formulated diets. Among 968-bp sequences, 111 variable sites were identified. One variable site showed close association with the individual performance of specimens fed with formulated diets. The commercial diet for Chinese sturgeons usually contains high levels of lipids. Lipoprotein lipase (LPL) and hepatic lipase (HL) are two members of the lipase gene family, which are essential for the utilization of dietary lipid. Single nucleotide polymorphisms (SNPs) in intron 7 were detected in the two experimental groups of Chinese sturgeons. We were able to demonstrate that one SNP in the LPL gene and one SNP in the HL gene showed close association with the performance of sturgeons on the formulated diet.
