The experiment consisted in evaluating the productive behavior of fattening chicken, fed with fish meal, with different levels of inclusion of fish solubles, obtained starting from stickwater which was stored in plant for different times. Five hundred and sixty, non-sexed, four days-old Hubbard broilers chicken, were used, distributed into seven treatments with four replications of twenty chicken each one. The experimental design was at random blocks, with a 2x3 factorial arrangement, in which the variables were: a) storage time of the stickwater (6 and 24 hours), and b) levels of inclusion of fish solubles in the fish meal (4.6, 9.3 and 14.0%), including a comparative basis which were suited to a standard or common fish meal, without incorporating fish solubles. The evaluations were live body weight variations, food consumption, alimentary conversion and chicken death rate. The increases on live weight of the chicken, for the total period, fluctuated between 1568 and 1698 g/chick; the food consumption varied from 4045 to 4437 g/chick; the alimentary conversion was from 2.46 to 2.79 kg/kg and the death rate reached a value of 2.14%. It was concluded that the use of fish solubles in chicken feeding did not alter their productive behavior. The results showed that it is feasible to retrieve the fish solubles, starting from stickwater stored in plant for up to 24 hours, with consequent environmental and economic profit for the industry.
