Research Progress towards Fishing Vessel Technology for Sustainable Use of Fisheries Resources

Abstract

For realising sustainable use of fisheries resources, new types of fishing vessel system should be developed because existing system has been implicitly optimised for unlimited amount of fish resources. Several research attempts in this research direction of fishing vessel technology are overviewed.
In techno-economic analyses on fishing vessel operation, the author updated the procedure for dynamically modelling variation of fish biomass as well as technical aspects of fishing vessel and cash-flow. As a result, his numerical results provided both possible scenarios towards overfishing and sustainable utilisation.
For safety and environment protection, relationship between new international regulations and recent researches is remarked. Efforts for improving onboard working conditions, including riding comfort and automatic control, and environment prevention, including use of wind energy, are also mentioned.
