Optimum temperature for the growth form of tiger grouper (Epinephelus fuscoguttatus ♀) × giant grouper (E. lanceolatus ♂) Hybrid

The growth form and condition of the tiger grouper × giant grouper (TGGG) hybrid were evaluated under four temperatures (22°C, 26°C, 30°C, and 34°C) and two diets (pellet and shrimp). The growth form of fish was determined over a 30 day experimental period using the length–weight relationship (LWR)...
