Abstract

Skipjack tuna (Katsuwonus pelamis), should be managed properly because even though it is renewable, natural resources can be depleted. One approach in managing fish resources is by modeling. The purpose of this study is to determine the maximum sustainable yield, the level of utilization and effort of skipjack tuna. Data on catches as well as catch efforts of skipjack tuna were collected from 9 fisheries year books of Luwu Kabupaten (District). The surplus production model used is the Schaefer, Fox, Walter & Hilborn model. Schaefer model obtained by MSY = 1541.08 tons and Fopt = 243 trips; Fox model obtained maximum sustainable yield value (YMSY) of 1602,244 tons, maximum sustainable fishing effort (fMSY) of 303 units and maximum sustainable CpUE value (UMSY) of 5.29 tons trip-1; the Walter & Hilborn model found potential stocks of sustainable reserves (Be) skipjack in Luwu district amounted to 935.72 tons year-1. Utilization rates of the skpjack tuina indicate the fish is still under exploitation.

Abstract

This study aims to (1) examine the physical and chemical aspects of marine oceanography, (2) determine the suitability of location and swimming crab culture techniques in submerged net cages, (3) find out the management strategies of crab culture management in submerged net cages. The results showed that the suitability of waters for crab cultivation activities in the karamba nets was submerged by using indicators of temperature, salinity, oxygen, pH and brightness obtained two suitability criteria, namely sesai and not. The results of the suitability analysis of crab cultivation land using a Geographic Information System (GIS) obtained two criteria for suitability of cultivated land with an area of each appropriate category that is 46,785.32 ha and not according to 1,152.4 ha. The results of management strategies that can be applied to realize integrated management of small crab culture include: 1) Development and socialization of small crab culture; 2) Management of integrated small crab cultivation; 3) Law enforcement related to the destruction of coastal ecosystems 4) Prohibition of capturing crabs laying eggs; 5) Construction of small crab hatcheries for small crab cultivation needs; 6) Development and provision of venture capital.
