- W4386660908 abstract "Given the importance of small pelagic resources for the livelihood of a coastal community, the present study aimed to determine its stock status to evaluate fishery sustainability. The catch of pelagic fish and fishing trips from multi-fishing gears were collected based on a daily-catch monitoring program by Archipelagic Fishing Port of Prigi during 2005 and 2018. Five surplus production models and the Fishing Power Index (FPI) also were applied to develop the catch per unit of effort as a relative abundance index. As a result, the Walter and Hilborn model (WH) was chosen as the best fit model relied on the highest coefficient of determination compared to other models (R2 = 0.637). The estimated intrinsic growth rate (r), catchability coefficient (q), and carrying capacity (K) were 5.89 tons per year, 0.0003 ton per unit, and 9,920 tons per year, respectively. The CMSY and FMSY were estimated as 14,609 tons per year and 7,873 trips per year, respectively. For economical sustainability, the CMSY and FMSY level were estimated at 14,307 tons per year and 6,742 trips per year, respectively. The average of actual trips for the last five years is greater than the optimum fishing effort, hence, an overfishing status was defined for small pelagic fishery. Therefore, some precaution approaches can be initiated in maintaining the resource sustainability and generating optimum economic benefits around the coastal area." @default.
