Abstract: The objective of this paper was to study the development of Piracanjuba (Brycon orbignyanus) in tanks under differents organic fertilizers. The experiment, entirely randomized, was accomplished in 16 tanks of 1000 liters, fertilized with manures of bovine (BOV), pigs (SUI), chickens (FRG) and others without fertilizer (SAO), using 15 fish/m3 with an initial average weight and length of 10,87+0,31 g e 9,78+0,07 cm. After 30 days, the experiment showed a uniform development of the fish and high survival rate in thestudied density. The treatments presented significant statistical differences (P<0,05) for weight gain and daily growth, except for the treatments BOV and SUI when compared to each other. The temperature and the dissolved oxygen were the abiotic factors that exerced a larger influence on the aquatic biota, affecting the development of the fish. Among the phytoplankton there was a larger presence of nanoplanktonic organisms favoring the development of the zooplankton, mainly the Clorophyta, with the Scenedesmus species, and the Cianophyta, with the Microcystis species, and among the zooplankton,the largest presence was of the rotifera from the species Brachionus and Keratella, followed by the copepods. The treatment fertilized with manure of chickens made possible a larger development of the plankton community, and better results of the development of the fish, demonstrating the importance of natural food in its diet. O objetivo deste trabalho foi estudar o desenvolvimento de juvenis de Piracanjuba (Brycon orbignyanus), em tanques com aduba es organicas. O experimento, inteiramente casualizado, foi realizado em 16 tanques de 1000 litros, adubados com estercos de bovinos (BOV), suínos (SUI), frangos de corte (FRG) e outros sem aduba o (SAO), utilizando 15 peixes/m3 com peso e comprimento médios iniciais de 10,87+0,31 g e 9,78+0,07 cm. Após 30 dias, o experimento mostrou um desenvolvimento uniforme dos peixes e alta taxa de sobrevivência na densidade estudada. Os tratamentos apresentaram diferen as estatisticamente significativas (p < 0,05) para ganho de peso e crescimento diário, com exce o dos tratamentos BOV e SUI quando comparados entre si. A temperatura e o oxigênio dissolvido foram os fatores abióticos que exerceram maior influência sobre a biota aquática, afetando o desenvolvimento dos peixes. Entre o fitoplancton houve maior abundancia de organismos nanoplanct nicos favorecendo o desenvolvimento do zooplancton, destacando-se as clorófitas, com o gênero Scenedesmus, e as cianofíceas, com o gênero Microcystis, e entre o zooplancton, a maio

Abstract: This study aimed to evaluate the growth rate and survival of mandi-pintado (Pimelodus britskii) larvae submitted to different feeding management. The experiment was conducted in a completely randomized design with four treatments and five replicates in a tank with 30 liters of water, each containing 30 larvae (0.032 ± 0.0048g and 8.22 ± 0.40mm). The treatments consisted of larvae fed with artemia; diet; artemia + diet; and artemia for two weeks + diet. Fish fed with artemia + diet showed greater weight and length, when compared to other feeding managements. The fish fed only with diet showed the worst performance. For the mandi-pintado larval rearing, the use of artemia combined with diet provides the best results for survival and growth.

Abstract: The experiment verified the development of Igua u′s surubim (Steindachneridion sp.) larvae, submitted to different diets in darkness. 35L-aquariums were used, in a completely randomized design, with five treatments and four repetitions. Each aquarium had 15 larvae with 8,35±0,85 mm and 6,75±0,64 mg, and the treatments were the following diets: Artemia(A); ration(R); zooplankton(Z); Artemia+ration(A+R); and zooplankton+ration (Z+R); After 29 days, the treatments A+R and Z+R was 1036 mg and 859 mg, respectively, significantly higher (P < 0,01), that A and Z, with 536 and 270 mg, respectively. In the treatment R there was no larvae survival, and presented high cannibalism (71%), which was also observed in other treatments, in smaller rates. This results led to the conclusions that the association of live and artificial diets in darkness provided best development, but it does not reduce the cannibalism. O experimento verificou o desenvolvimento de larvas de surubim do Igua u (Steindachneridion sp), submetidas a diferentes dietas em ambiente n o iluminado. Foram utilizados aquários de 35 litros, em um delineamento inteiramente casualizado, com cinco tratamentos e quatro repeti es. Colocaram-se 15 larvas por aquário, com 8,35±0,85 mm e 6,75±0,64 mg. Os tratamentos foram as dietas: Artemia(A); ra o(R); zooplancton(Z); Artemia+ra o(A+R); e zooplancton+ra o (Z+R). Após 29 dias, os resultados mostraram que os tratamentos A+R e Z+R obtiveram pesos médios finais de 1036 e 859 mg, significativamente maiores (p < 0,01), que A e Z, com 536 e 270 mg, respectivamente. No tratamento R n o houve sobrevivência de larvas, e apresentou alta taxa de canibalismo (71%), o qual foi também observado nos outros tratamentos, em menores taxas. Pode-se concluir que a associa o de alimentos vivos e dietas artificiais em ambientes escuros apresenta bom desenvolvimento mas n o reduz o canibalismo.

Abstract: This study aimed to verify the diel and vertical dynamic characteristics in limnological environment for rearing native fish in net-cage at the reservoir of Itaipu Binacional. The parameters evaluated were water temperature, dissolved oxygen, electrical conductivity, pH, phosphorus, nitrite and ammonia. It was found that there was diel variation for all parameters, except for ammonia and phosphorus. But the variables are in the recommended limits for aquaculture, with the exception of dissolved oxygen that showed critical rates at night. For the vertical distribution concentrations of physical and chemical parameters of water did not exceed the limit established by CONAMA Resolution 357/05 for fish rearing, however, there was vertical variation for nitrite and phosphorus. KEY WORDS: Aquaculture, intensive culture, limnology, water quality.
