Gamak Bay is a highly productive fishing area in Jeollanam-do as both major spawning and nursery ground for fisheries resources. The purpose of this study is to investigate the variation of location fishing gear and migration, behavior patterns of fishes in the Gamak Bay. Based on this, it will be able to provide information that can predict the location of fishermens fishing grounds selection. The survey on the location of fishing gear was conducted in parallel with question survey and boarding survey. The question survey was conducted on 23 members of the Ungcheon and the Ssangbong fishing village in the Gamak Bay. In the boarding survey, location of fishing gear was moved to clockwise rotation as the season change from July 2018 to June 2019. It is judged that fishes caught by season change their habitat in response to the characteristics of environment in the bay. The number of fishing gear by season was large in the spring and fall, and relatively small in the summer and autumn. In the spring, gillnet gear was increased around Dewegyeongdo and Sogyeongdo to catch increasing priced Marbled flounder, Psudopleuronectes yokohamae, Purple pike conger. In the summer, the installation of longline gear around Dolsando was increased to catch the Muraeneresox cinereus, which represents Yeosu area. In the fall and winter, the Long arm octopus was mainly caught in the trap gear, which was set up on the low and dense central part in the bay. As a result, location information was obtained through the nursery ground of major fish species in the Gamak Bay.

As a series of research plan, this study is to provide basic data necessary for the development of fishing industry which will contribute in establishing sound fishing culture in Jeju island through systematic management of fishing, protection of fishery resources and establishment of safety measures for fishermen in accordance with ‘Fishing Management and Support Act’. To attain the proposed objective, this study conducted literature review and surveys on restriction standards of harmful substances generated from fishing equipment and baits, examined the current status of fishing management in popular fishing sites of other cities, and then reviewed and analyzed the fishing management and fishing-restriction zones in Jeju island. The survey on the opinions on the restriction criteria of fishing methods, tools and period, including the acceptable standards for harmful substances showed that general fishermen preferred ‘alleviating the measure (44.8%)’ to ‘aggravating the measure (23.0%)’. Meanwhile, maritime police showed dominant opinion toward ‘aggravating the restriction (52.2%)’ over ‘alleviating the measure (4.3%)’. Furthermore, fishing-related enterprise is favored ‘aggravating the restriction (32.6%)’ over ‘alleviating the measure (27.9%)’. In the survey on the tolerance of fishing baits including criterion for content of certain substance in different types of bait, it showed 57.5% of general fishermen preferred alleviating restriction criteria while 20.7% of them favored tougher restriction. Whereas, 33.3% of maritime police group insisted such fishing baits should be more restricted while 16.7% answered it should be alleviated. 35.9% of fishing-related enterprise was in favor of alleviation while 14.3% preferred aggravation. Upon investigation on the status of fishing management in other cities and towns, it turned out that most of them had safety and convenience facilities, installed warning and guide signs in fishing sites, and set no fishing zones. The review of fishing management and restricted area showed that 10 sites required access restriction and 2 of 10 sites were considered to be partially restricted for weather and season. 82 fishing sites were regarded as unnecessary to be restricted and installation of safety facility and guide signs is necessary for the safety of fishermen.

As part of a series of studies about improving yellow croaker drift gill net fishing gear and the development of a labor-saving fishing system, we installed a labor-saving-type, five-step-drum net hauler, and a triple-V-type net hauler in 108 Daeheung-ho, a fishing boat which operates drift gill nets for yellow croakers mainly in the sea near Chu-ja Island. Net damage with the labor-saving-type, five-step-drum net hauler is lower than for the triple-V-type net hauler. In addition, there was a reduction in the standard operational crew of two people. The lead time for hauling the labor-saving net was approximately 10% and 19.2% less than for hauling the triple-V-type net hauler and for hauling by hand, respectively. It was found that there were fewer slip in fishing gear and less damage to the wing of the drum as well as less damage to the fish when the labor-saving-type, five-step-drum net hauler was used than when the triple-V-type net hauler was used. In the survey, the lead time for hauling the net was approximately 21.6% and 45.2% more effective than hauling with the triple-V-type net hauler and hauling by hand, respectively. The crew was reduced by approximately 18.2% and 25% than when hauling with the triple-V-type net hauler and hauling by hand, respectively. In addition, cessation of operation and damage to the fish were reduced when compared to the triple-V-type net hauler and hauling by hand.

In this study, we designed a fishing system to reproduce the underwater movement of the living Sword tip squid (Loligo edulis) used as bait in the red seabream long line fishery, and conducted the experiment of the fishing operation in 2 ways, i.e., a pole and line fishing method (fishermen) and a bait control fishing system used at fishing sites. Based on the catches in fishing operation, the experiment was conducted over a six times (2014 & 2015), and then 107 fishes were caught by the line fishing method while 57 fishes were caught by the bait control fishing system. The fishermen method actively controlled the speed of gear movement upward and downward while checking the reaction of red seabreams to the bite in the process which a jerk was transmitted to single line hook fishing gear manually. The bait control fishing system is a passive method which fishermen visually check only the movements at the end of fishing pole, enabled differentiation of bite reactions of red seabream during fishing operation. Thus, the difference between fishermen method and the bait control fishing system was found to about 53.3% in the catches. We confirmed the possibility of a site fishing operation based on the bait control fishing system designed newly as a result of this study. Improvement is in several areas for commercialization at the site. This fishing system is expected to be able to find wide-ranging applications as a new labor-saving method for the fishing red seabreams if it is applied to the fishing sites after aforesaid process.
