Abstract & Overview
Bonito (Auxis rochei), needs to be managed well because even as a renewable natural resource, but can undergo depletion or extinction. One of the approach in the management of fish resources is by modeling. The analysis was performed aiming to get the best estimate for the surplus production model to determine the maximum sustainable yields (MSY), utilization level, and effort levelof bonito.The data of catch and fishing effort bonito collected from the Marine and Fisheries Service of the Talaud Regency and the North Sulawesi Province. Best Surplus Production Model, which is used to assess the potential of bonito is Schaefer Model. Optimal effort (EMSY) of 8,489 trips per year, with catches of optimal CMSY 2,453.77 tons per year. The effort level for 2012 is 193.99%, which shows the inefficiency of effort, the utilization level of 94.86%, showing indicate will occur overfishing.
