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.
