3.1. Body chemical composition and energy content
The contents of moisture, protein, lipid, ash and energy in the body
of cobia at different size and temperature treatments are listed in
Table 1.
Fish chemical composition and energy content were affected significantly
by both water temperature and fish size (P b 0.05). In a given
fish size group the contents of protein, lipid and energy were higher at
27, 31 and 33 °C than at 21 and 35 °C. At each temperature the contents
of protein, lipid and energy for cobia increased significantly with
increasing fish size.
