An Analysis of Little Tuna Resources Management Options in the East Coast of Minahasa, North Sulawesi Province
Abstract
Presently, the utilization of little tuna resource in the Minahasa coastal waters is not well managed by the local fisheries authority. In the other word, the local government has not sufficient capacity to protect their local fish resources. The management regime used by the local government is quasi open access regime which no control on fisheries capacity in terms of input and output. In this regards, this study can contribute in giving alternative scenario to manage little tuna resources in study area. Using Gordon-Schaefer model, it has been revealed that the Maximum Sustainable Yield (MSY) is estimated at the level of 744.27 ton, while Maximum Economic Yield (MEY) 267.73 tons, Optimum Sustainable Yield (OSY) 275.90 tons and Open Access Yield (OAY) 476.02 tons respectively. In terms of effort, theses level would be 9,453 trips; 1,889 trips; 1,954 trips; and 3,778 trips. From the stekholders analysis, it can be also obtaiend that directorate general of capture fisheries (national level), marine and fisheries service (regional level), regional legislative, fisheries and marine service, regional planning and development board, non goverment organization, private sectors, fishing boat owner and fishermen group (local level) are the most strategic stakeholders. Based on this identification, therefere, trade-off analysis on management scenarios has been undertaken. From the actual condition, it has been indicated that actual production level has been excessed the level of MSY. It can be said that the actual condition of resources utilitization has been biological overfished. From the effort point of view, the condition of actual effort also has been excessed the level of OAY or has been economically overfished. Furthermore, optimal economic rent can be achieved when little tuna management is operated MEY and OSY level. From the results of trade-off analysis, it can be revealed that output control scenario can be considered as the best scenario due to its total score more than input control scenario and output- input control scenario. However, in the real implementation, the output control scenario and input control scenario can be implemented if the government reducing the production is 718.70 tons, 533.24 tons and its effort level is 7,772 trips, 10,150 trips respectively.
