Regarding fish growth, there were no significant
differences among the low and high biomass groups
in terms of initial weight (26.0 ± 1.9 g at a density of
2 kg fish m–3, 26.1 ± 2.8 g at a density of 5 kg fish m–3),
final weights (44.4 ± 2.9 g at 2 kg fish m–3, 53.1 ± 3.3 g
at 5 kg fish m–3) or weight gain (18.4 ± 4.8 g at 2 kg
fish m–3, 26.9 ± 6.1 g at 5 kg fish m–3). The total amount
of food provided per fish was also similar among treatments
(23.60 ± 2.72 g at 2 kg fish m–3, 29.35 ± 1.52 g
at 5 kg fish m–3).
