| Miêu tả: | Postlarvae of the Genus Penaeus were collected once a month from November/94 to April/95 at Cocoroca beach in the Gulf of Nicoya, Costa Rica. They were identified morphologically, and those of P. occidentalis were studied. It was revealed that the postlarvae of P. occidentalis occupied 65.6 % of the total individuals collected, and 24.1 - 94.9% of the monthly composition, and their distribution density varied from 0.7-5.8 individuals/m2. The carapace length(CL) of the postlarvae of P. occidentalis ranged from 1.55 to 9.58 mm, which suggested a migratory size of them. The frequency of the CL showed a skewed distribution, which suggested a migratory pattern of the postlarvae of that species. The relative growths of the 6th abdominal somite and the carpus of the third pereopod of the postlarvae of P. occidentalis were also examined against the CL. |
