Abstract

This work aimed to evaluate the growth of the shrimp Farfantepenaeus subtilis submitted to different fertilization regimes using organic and inorganic fertilizers. The experimental design consisted of three treatments in triplicate: control (CT) - 3 mg L-1 of urea and 0.3 mg L-1 of monoammonium phosphate; wheat bran (FT) - 25 g m-2; and soybean bran (FS) - 18.75 g m-2. Nine 500 L fiber glass tanks were stocked with 16 shrimp m-2 (≈ 2.7 g). Animals were fed daily with pelleted feed (35% crude protein). Biweekly, water quality was monitored and shrimp samples were collected to evaluate growth and adjust the feed quantity. Water quality maintained adequate to shrimp culture during the experimental period. Growth results did not differ significantly (p > 0.05) among treatments. Mean growth rate and survival were 0.44 g week-1 and 75%, respectively. Therefore, the protocols evaluated were efficient for shrimp growth and water quality maintenance.
