In order to test the feasibility of producing a breeding stock of nonindigenous penaeid shrimp in closed pond systems tests were performed using second season animals previously overwintered in a heated raceway. The shrimp, originally stocked as postlarvae, were reared to 150.0 mm in length and 30.0 g in weight. The shrimp were then harvested, overwintered, then returned to a 0.1 ha pond in Corpus Christi, Texas. In their second season the shrimp grew to 190.0 mm and 52.0 g and exhibited signs of sexual maturity. Sampling of the pond produced mated females that were removed from the pond and spawned in the laboratory. |
