【 摘 要 】

Devis' anchovy (Encrasicholina devisi) are a group of small pelagic fishes, which is thought to be one of the most abundant fishery resources in Indonesian waters. The high utilized of this resources will certainly affect to population status. This research aimed to know the exploitation status of anchovy in Kei Island waters. Sampling was carried out by using the data collected from lift net catches during April to July 2016 at Sathean, Selayar and Lebetawi, Kei Islands. A total of 3,524 anchovies were analyzed based on total length that ranged from 23 to 87 mm with a mean length of 55.4 ± 11.8 mm. The von Bertalanffy growth parameters estimated were L∞= 89.25 mm and K = 0.74 year-1, with the growth models equation is Lt= 89.25 (1 - e-0.74(t+0.161). The result of mortality analysis showed that Z = 2.97, M = 1.098, F= 1.87 year-1and E = 0.63. This study reveals that exploitation status of anchovy in Kei Island is on fully exploited and leads to the over exploited condition.
