Abstract
Jigging with artificial lights squid jigging and deploying of large scale trapnet also known as a setnet in Japan are the major methods to capture Japanese common squid Todarodes pacificus in western Japan Squid jigging is a highly selective fishing method However it consumes large amount of energy for steaming to the fishing ground and for lighting In contrast trapnet fishing requires substantially less energy but its capture efficiency is strongly influenced by its stationary mode of capture The primary objective of this study was to analyze how various environmental and biological factors such as the lunar cycle tidal condition wind direction and squid abundance affect the capture efficiency of squid jigging and trapnet fishing We analyzed the effect of these factors on squid catch in five Fisheries Cooperative Associations located on four islands in Nagasaki Prefecture western Japan Our analysis shows that squid catch in jigging and trapnet fishing is mainly influenced by the lunar cycle but also tide and wind direction play a marked role In addition squid abundance significantly affects the catches in trapnet fishing Recommendations are made to improve the overall profitability of squid fishing by proper choice of the capture method location and season
