Analysis on the fishing capacity of squid stick-held dip net fishery in the northeastern waters of Taiwan / 台灣東北部海域鎖管棒受網漁業捕撈能力之分析

碩士 / 國立臺灣海洋大學 / 環境生物與漁業科學學系 / 103 / This study aimed to investigate fishing capacity of squid stick-held dip net fisheries in the water off northeastern Taiwan using data envelopment analysis (DEA). Data required for DEA analysis were collected from 8 squid stick held dip net fishing vessels operating in the water off northeastern Taiwan during 2008-2013. Fishing vessel (tonnage and horsepower), fishing operation (number of net deployment and working day), fishing lamp (number and power), hoop net (length and depth) were selected as input factors for DEA analysis while catch abundance was selected as the output factor. The results indicated that the average capacity utilization rate of fishing vessel, fishing operation, fishing lamp and hoop net was 69%, 75%, 75% and 52%, respectively. The overcapcity of all input factors was evident in the present study except for horsepower of fishing vessel and number of fishing lamp. The average capacity utilization rate varied annually. The average capacity utilization rate of fishing vessel (46.5%), fishing operation (56.9%), fishing lamp (49.7%) and hoop net (56.9%) was at the lowest level in 2009. The average capacity utilization rate also varied with targeted fish species. The average capacity utilization rate was 64% for skipjacks, 42% for cephalopods, 39% for mackerels and scads, and 37% for others. Taken together, it is feasible to measure fishing capacity of squid stick-held dip net fisheries in the water off northeastern Taiwan using DEA. Results from this work can offer scientific evidence required for the management of squid stick-held dip net fisheries in the water off northeastern Taiwan
