, Selar crumenophthalmus
, Decapterus russelli
and Amblygaster sirm
were the dominant small pelagic fishes in Hinatuan Passage contributing 32% of the total production in the area. This paper presents the status of these four dominant small pelagic fishes as to their abundance, seasonality, length frequency distribution and population parameters relevant to the management and sustainability of the fishery resources in the area.
Results show that commercial Danish seines, Ring nets, Bagnets and municipal multiple hook and lines and Drift gillnets, were the main gears exploiting these four small pelagic fishes. It was shown further in the analysis of fish samples that these gears caught an average of 77% immature fish which did not even reach its length at first maturity, though the growth rate (K) and length infinity (Loo) vary by species. The present level of exploitation rates ranged from 0.4-0.84 which is an indication of biological overfishing. Pages: 286-303 | 940 Views 46 DownloadsDownload Full Article:
