Effect of the initial stocking body weight on growth of spotted rose snapper Lutjanus guttatus (Steindachner, 1869) in marine floating cages
Spotted rose snapper were stocked at body weight sizes of 24.5 ± 3.7 g, 55.4 ± 3.5 g, and 110.2 ± 4.6 g in three replicated marine floating cages of 100 m³ and reared for 153 days at Santa Cruz de Miramar in Nayarit, Mexico, to determine the appropriate stocking body weight size. Caged snapper were...
