A bio-Economic Model Approach: Measuring The Exploitation of the Peninsular Malaysia Fishery

Thesis summary

In Malaysia, most of the studies conducted in marine fisheries have mainly focussed on fishing capacity and productivity growth (Kirkley, 1984; Davis et al., 1987; Jahara Abdullah, 1993; Kirkley et al., 2003; Squires et al., 2003). They found that fishing vessels operated in all fishing zones have reached close to the full technical efficiency and capacity utilization. Abu Talib et al. (2003) found that the demersal species are already overexploited and the level of fishing effort is beyond that needed for maximum sustainable yield. Islam et al. (2011) found that catch per unit of effort was the highest for purse seine on the east and west coasts of Peninsular Malaysia. Stobutzki et al.(2006) used trawl survey time series data to estimate biomass in Peninsular Malaysia. They found that biomass has declined in both east and west coast of Peninsular Malaysia. The only study related to bioeconomic analysis of the demersal fisheries in northwest Peninsular Malaysia was conducted by Tai Shzee Yew (1996). He found that the demersal stock was overfished biologically and economically. In Malaysia, however, little work has been done in the measurement and assessment of over fishing (biological and economic) and fishing capacity utilization. This study will estimate the sustainable catch and effort by various types of gears in Peninsular Malaysia. The main purpose of the research is to provide a current bioeconomic analysis of the Peninsular Malaysian fisheries and will estimate both economic and biological maximum levels of yield and effort.
