PROBLEM TO BE SOLVED: To promote the breeding of spiny lobster by heightening the bottom-clinging number of postlarvae and the survival rate of fry of the same.SOLUTION: A block 1 for breeding spiny lobsters obtained by forming, in side face parts, a plurality of kinds of concave parts having different sizes in inner diameters and depths for allowing postlarvae and fry of spiny lobsters to change the living places according to the growth is installed on a bedrock 7, and the block 1 for the breeding and seaweeds 6 are surrounded by a net to protect them from bite injury. As a result, the proliferation of the seaweeds 6, and the increase of the bottom-clinging number and the living number of postlarvae and fry of spiny lobsters are expected even in a seawater-damaged sea area caused by seaweed-eating fishes or the like to contribute to the secure and increase of the resource of the spiny lobsters.COPYRIGHT: (C)2013,JPO&INPIT【課題】ポストラーバの着底数及び稚エビの生残率をより高め、イセエビの増殖を促進する。【解決手段】ポストラーバ若しくは稚エビがその成長に合わせて棲み替えるための、内径及び奥行寸法の異なる複数種類の凹部を側面部に設けてなるイセエビ増殖用ブロック1を基盤7上に設置し、この増殖用ブロック1及び海藻類6を網により包囲して食害から防護することとした。これにより、藻食性魚類等による磯焼け海域であっても、海藻類6の増殖、及びポストラーバ若しくは稚エビの着底・棲息数の増加が期待され、イセエビ資源の確保及び増殖に資する。【選択図】図11
