“…Similar responses were observed by Papoutsoglou et al (2000) for common carp (Cyprimus carpio) juveniles reared in white, black and green tanks. However, the results differ for species that swim actively in the water column in search for food, such as the larvae of curimatá-pioa.…”

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.

“…Larvas de curimatá-pioa (P. costatus) apresentaram maior peso e comprimento final quando cultivadas em aquários de cor verde, em comparação às mantidas em aquários azul, marrom e preto (Pedreira et al, 2012). Cultivos de carpas (Cyprinus carpio) em aquários brancos favoreceram maior taxa de crescimento específico e melhor conversão alimentar do que o cultivo em fundo preto e verde (Papoutsoglou et al, 2000). Estes autores atribuíram o desempenho inferior nos aquários escuros às altas taxas de cortisol encontradas nos peixes cultivados nestes ambientes.…”

Resumo -O objetivo deste trabalho foi avaliar o efeito de diferentes cores de aquários na larvicultura da piabanha-do-pardo (Brycon sp.). Os tratamentos consistiram na utilização de aquários de cores claras (branca, verde e azul) e escuras (marrom e preta). Ao final do experimento, foram mensurados a sobrevivência, o peso, o comprimento total e a coloração das larvas, que foram comparados pelo teste de Tukey, a 5% de probabilidade. A sobrevivência foi menor (66,25%), com maior taxa de canibalismo (17,08%), no aquário de cor azul, quando comparado ao aquário de cor marrom (84,17%), com baixa taxa de canibalismo (6,25%). O comprimento total, o peso e a mortalidade não diferiram entre os tratamentos. A coloração das larvas escureceu progressivamente dos aquários mais claros para os mais escuros, o que interferiu no canibalismo e na sobrevivência. O aquário marrom promove maior valor de sobrevivência e menor taxa de canibalismo nas larvas de piabanha-do-pardo.Termos para indexação: Brycon, canibalismo, coloração, mortalidade, pigmentação. Larviculture of piabanha-do-pardo in aquariums of different colorsAbstract -The objective of this work was to evaluate the effect of different colors of aquariums on the larviculture of piabanha-do-pardo (Brycon sp.). The treatments consisted of the use of light-(white, green, and blue) and dark-(brown and black) colored aquariums. At the end of the experiment, survival, weight, total length, and color of the larvae were measured and compared by the Tukey test, at 5% probability. Survival was lower (66.25%), with a higher rate of cannibalism (17.08%), in the blue-colored aquarium when compared to the brown-colored one (84.17%), with a low rate of cannibalism (6.25%). Total length, weight, and mortality did not differ among treatments. The color of the larvae gradually darkened from the lighter to the darker aquariums, which interfered with cannibalism and survival. The brown aquarium promotes a greater survival value and a lower rate of cannibalism in larvae of piabanha-do-pardo.

“…Studies have concentrated on showing the effects of environmental colors on some mammals (1), birds (2) and fish (3), but the mechanisms are still unknown. In fish, some studies have shown that environmental color affects growth (4)(5)(6), feeding (7)(8)(9), food conversion rate (10), stress (10,11), aggression (12), and egg development (13).…”

We investigated the effects of environmental color on the reproductive behavior of Nile tilapia, Oreochromis niloticus. Two environmental colors were tested by covering the aquarium (60 x 60 x 40 cm) with white (12 groups) or blue (13 groups) cellophane and observing reproductive behavior in groups of 2 males (10.27 ± 0.45 cm) and 3 females (10.78 ± 0.45 cm) each. After assignment to the respective environmental color (similar luminosity = 100 to 120 Lux), the animals were observed until reproduction (identified by eggs in the female's mouth) or up to 10 days after the first nest building. Photoperiod was from 6:00 h to 18:00 h every day. Food was offered in excess once a day and water quality was similar among aquaria. Daily observations were made at 8:00, 11:00, 14:00 and 17:00 h regarding: a) latency to the first nest, b) number of nests, c) gravel weight removed (the male excavates the nest in the bottom of the aquarium), d) nest area, and e) mouthbrooding incubation (indication of reproduction). The proportion of reproducing fish was significantly higher (6 of 13) in the group exposed to the blue color compared the group exposed to the white color (1 of 12; Goodman's test of proportions). Moreover, males under blue light removed significantly larger masses of gravel (blue = 310.70 ± 343.50 g > white = 130.38 ± 102.70 g; P = 0.01) and constructed wider nests (blue = 207.93 ± 207.80 cm 2 > white = 97.68 ± 70.64 cm 2 ; P = 0.03) than the control (white). The other parameters did not differ significantly between light conditions. We concluded that reproduction in the presence of blue light was more frequent and intense than in the presence of white light.
