Effect of stocking density on growth performance and oxygen consumption of Nile tilapia (Oreochromis niloticus) under greenhouse conditions

ABSTRACT. The effects of stocking density on oxygen consumption and growth in Nile tilapia (Oreochromis niloticus) under greenhouse conditions were investigated in this experiment. Fingerlings with 1.57 ± 0.14 g mean body weight were stocked in 972 L, rectangular plastic tanks placed inside a polyet...

It was found that growth rate of T1 (0.38 g day-1; 4.65% day-1) and T2 (0.21 g day-1; 3.68% day-1) was significantly higher than T3 (0.11 g day-1; 2.67% day-1).

Effect of stocking density on growth performance and oxygen consumption of Nile tilapia (Oreochromis niloticus) under greenhouse conditions
description ABSTRACT. The effects of stocking density on oxygen consumption and growth in Nile tilapia (Oreochromis niloticus) under greenhouse conditions were investigated in this experiment. Fingerlings with 1.57 ± 0.14 g mean body weight were stocked in 972 L, rectangular plastic tanks placed inside a polyethylene greenhouse 504 m², at three densities 90 (T1), 180 (T2), and 270 (T3) ind m-3 (biomass of 0.14, 0.28, and 0.42 kg m-3). Fish were feeding with a commercial diet for Nile tilapia (Api-Tilapia 1, MaltaCleyton® with 50%, protein and 12% lipid) to apparent satiation, three times a day, for 60 days.
