STUDY OF PURSE LINE WITHDRAWAL SPEED AND CATCHING TIME TO CATCH NUMBER OF PURSE SEINER BASED IN PROBOLINGGO CITY EAST JAVA PROVINCIAL


There are two factors that important to the successfull of catching activities using purse seine, purse line withdrawal speed (as internal factor) and catching time (as external factor). The purpose of this study was to determine the condition of purse seiner based in Probolinggo City, determine the effect of purse line haul withdrawal speed and determine the effect of catching time to fish catched. The method used in this research is descriptive method and quasi experiments.
The number of purse seiner based in Probolinggo City, has decreased. Purse seine fishing gear, is accordance to the Indonesia National Standard. Supporting tools that used are lamp (as an attractor) and gardan (as puller purse line), which generating by the ship main engine as a generator. The optimal of purse line withdrawal speed is 1,49 m/s with 1.138 kg in catched, 1,07 m/s withdrawal speed just able to catch 5 kg and this is the lowest number during observation. The best time to catching is during the dark moon phase (new moon) with the number of catch was 14.716 kg. The best catching is at 2:00 a.m. WIB closely to 2.543 kg in catch. It can conclude that purse line haul withdrawal speed and catching time, influencial toward catch number. This study can suggest three things, firstly the use of power block on the purse seine net hauling process can help it easier and faster. Secondly, auxiliary equipment (rumpon and ‘lampu celup laut dalam’) can be used to effectively attract the fish. Thirdly, fisherman calendar which based on the moon phase and a column listing of the catched number need be issued to optimazed the catch number.
