Abstract

人工魚礁を利用した漁場造成や増殖場の造成を効果的に進める上で重要なことは、施設の位置選定と構造である。それらを決めるためには魚の移動生態や魚礁に対する行動生態を明確にすることが重要である。ここでは沿岸水域における魚群の移動や魚礁に対する行動生態と、魚礁の生産効果について検討する。

The artificial reef plays an important role in creating productive fishing ground and nursery. The aim of thisstudy is to obtain basic understanding of the function of artificial reef which is closely related to the behaviorpattem of fish. The first point of this study concems adequacy of the location of reef that has relation to the migration behavior of fish in coastal waters and to the reaction of fish to the reef. The second point related tothe diel changes in aggregation of fish in the reef area in accordance with environmental water movement andunderwater irradiance. The third point is that structural properties of the reef, such us a shape and a vacancy inthe reef, has an effect on aggregation of commercial fish and cohabiting organisms including the young. In thelast point, the current status of fishing activities in the reef area is described by vessel and gears used, fishingseasons and catches of target species. The reef area is used by various coastal fisheries with emphasis on fisheshaving high marketprice.Long-term artificial reef management is an important research subject to develop coastal fisheries and tosustain local fish stock in a favorable condition.
