| Diapterus rhombeus (Cuvier, 1829) is one of the most common Gerreidae species in the estuarine region at the Guaratuba Bay, Southern Brazil. Based on studies developed between July, 1993 and January, 1997, it was observed that its presence in the mangrove area is not regular: the smallest individuais are more abundam during late summer and in autumn, and the largest ones during spring and early summer. Its diet comprises plant material and invertebrates, specially polychaets. The morphological aspects of the gonads, the monthly changes on the Condition Factor, and lhe monthly distribution of the individual size groups, suggest that this population spawns during the spring, out the estuarine region. The smaller individuais use the mangrove area of Guaratuba... |

| ABSTRACT The growth of the Brazilian aquaculture has stimulated the development of the productive chain of native species, including marine environment. The objective of this study was to evaluate the growth performance of juvenile mojarra fish (Diapterus rhombeus) fed diets containing different concentrations of crude protein (32, 36, 40 and 44 g 100 g-1). The 80 juvenile mojarra (7.2±1.5 g) were kept in 16 circular tanks (150 L). The study design used was completely randomized with four treatments and four repetitions. The fish were fed four times a day. At the end of the experiment (60 days) the final weight, feed intake, weight gain (WG), feed:gain ratio (FGR), protein efficiency rate (PER), energy efficiency rate, specific growth, survival rate and,... |
