Resumo: The color effect on survival rate and development of tambaqui larvae, Colossoma macropomum, in fish tanks, during a 20 day period, was analyzed. Larvae were fed “ad libitum” and measurements of four limnological variables were conducted daily. Water temperature varied between 24 to 27.8C and 24.0 to 27.7C in the dark brown and light green colored tanks, respectively. Dissolved oxygen level remained over 6.5 mg/L, pH was alkaline and water conductivity higher than 30 &micro;S/cm. The dark brown treatment displayed significantly (P < 0.05) lower survival rate compared to treatment with light green. Identical effect, however, was not reported with average weight, biomass and larvae total length. Results showed that tank color influences larvae survival rates, where the light green color makes it easier for the larvae to visualize the prey

As larvas foram alimentadas “ad libitum” e diariamente foi realizada amostragem de quatro variáveis limnológicas. A temperatura da água oscilou de 24,0 a 27,8 oC no marrom- escuro e de 24,0 a 27,7oC no verde-claro; a concentração de oxigênio dissolvido permaneceu acima de 6,5 mg/L; o pH manteve-se alcalino e a condutividade, acima de 30 &micro;S/cm. O tratamento marrom-escuro apresentou sobrevivência média significativamente menor (P < 0,05) que o verde-claro. O mesmo não ocorreu com os dados de peso médio, biomassa e comprimento total das larvas. Os resultados obtidos confirmaram que ocorre uma interferência da cor dos aquários na sobrevivência larval, onde o verde claro facilitou a alimentação através da visualização da presa pela larvaUniversidade Estadual De Maringá2008-05-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/271110.4025/actascibiolsci.v23i0.2711Acta Scientiarum.
