Fish were sampled from the cages to represent the average fish weight for the cage.
Fish growth is assumed to be influenced by three fundamental factors: fish weight, water temperature, and ration size.
Fish weight was recorded at the beginning and end of the experiment, in order to confirm that the fish had consumed the test diets and had a positive energy balance.
Furthermore, the bioconcentration factor (BCF) was significantly negatively correlated with fish weight in both social treatments.
Initial fish weight was 1652 ± 6 g (mean ± SEM) and the experiment lasted for 28 weeks from December 2004.
Whole body lipid varied between seasons, as a consequence of dietary lipid levels, and increased as fish weight increased.
The relationship between December fish weight and maturation in both experiments was modeled with a quadratic equation.
At the end of this stage (average fish weight, 255 g), the fish were selected into three sizes, except for D1.
Regression analysis on the validated results indicated a strong correlation between predicted and observed data for TAN, temperature, NO3 and fish weight.
In stage I (initial fish weight, 78 g), four stocking densities were tested: D1 800, D2 2000, D3 2500 and D4 3000 fish/cage, with three replicates.
I am talking about the increased popularity of big tackle for big saltwater fish, weight 17 rods and flies the size of the trout you catch on those one-weight outfits.
