| Miêu tả: | Fish samples collected at least once a month in the Nicoya Gulf, Costa Rica, using a gill net, revealed that the ichthyological community is dominated by four families: Sciaenidae (27.6% of the species), Haemulidae (15.0%), Carangidae (11.5%) and Ariidae (8.1%). Out of 1,491 fishes collected, 28.3% were represented by the species Ilisha furthii (11.5%), Cetengraulis mysticetus (8.5%) and Cynoscion squamipinnis (8.3%). A 28.9% of the total captured weight (437,148.30 g) is given by C. squamipinnis (11.1%), Pomadasys leuciscus (9.2%) and Cynoscion phoxocephalus (8.57%). I furthii, C. squamipinnis and C. phoxocephalus were the only species, with at least 10 individuals per season, present in all samples. In contrast with I. furthii, which recorded relatively constant seasonal captures, the rest of the species showed random yearly and seasonal fluctuations in both number of individuals and average weight per sample. These non-systematic variations suggest that there is no identifiable pattern that relates the abundance to seasons. |
