Reproductive dynamics of the tiger prawn Penaeus esculentus, and a comparison with P. semisulcatus, in the North-western Gulf of Carpentaria, Australia

The minimum size at maturity for P. esculentus was 25 mm carapace length (CL), and 50 percent of the population were mature at 32 mm CL. The maximum proportion of mated females was 80 percent inseminated in the size range 32-50 mm CL. Eggs were produced throughout the year, but most consistently in...

Summary:The minimum size at maturity for P. esculentus was 25 mm carapace length (CL), and 50 percent of the population were mature at 32 mm CL. The maximum proportion of mated females was 80 percent inseminated in the size range 32-50 mm CL. Eggs were produced throughout the year, but most consistently in late winter and early spring. Spawning occurred within a limited area. P. esculentus matures at a small size (50 percent at 32 mm CL) then P. semisulcatus (50 percent at 39 mm CL), fecundity is lower, spawning is nearer inshore and egg production is less strongly seasonal
