IV. The Results of the Study for the Development
1. Investigations on the Type of Set-net and Attached Marine Animals and Plants
The type and current status of the set-net fishery which involves considerably diverse and large fishing equipments compared with other types of fishery were investigated. Through this, basic data for the development of net clearing system is provided for the purpose of enhancing fishing competitiveness. These data were also used for the development of net-set clearing system.
The marine creatures attached to the set-net are various depending on time and space such as the depth of water, season, and sea area but no studies have been performed regarding this.
Thus in this study, the marine creatures attached to the set-net were investigated to provide basic data for the development of net clearing system and the features of such creatures were described briefly.
2. Development of Primary Net Clearing system
Marine creatures attached to the net causes many problems and difficulties while lifting the net and fishing. Particularly in summer when the amount of the attached creatures is high, increased weight of the wet may cause safety related problems and other difficulties related with fishing. In addition, lifted net causes fugitive dust and foul odor during drying and removal of the attached matters, consequently deteriorating the image of the coastal area where tourists visit, and damaging the regional economy.
In this study, effort was made to solve the problems related with lifting the net and fishing using the set-net by the development of the primary net clearing system.
3. Development of Secondary Net Clearing System
Over 90% of the attached matters were removed from the net that was removed to the ground through the primary net clearing, and the secondary net-clearing system was developed to link the primary net clearing system to the fast repair of the net. Through this, time required for drying and separation of the net reduced by about 14 days, providing a solution for reduced manpower due to automation of the fishing and increased competitiveness.
V. Achievements of the Study and Plan for the Use of the Achievements
The possibility of the development of a new net clearing system has bee identified as described above in the development of set-net clearing system. As such various stages of studies are considered necessary for enhance the performance, usefulness and economical efficiency of the system.
In addition, promotion for application and distribution of related skills of crane and Derick is required to allow solve the manpower shortage and to allow them to be used in connection with net-clearing system.
