摘要：
PROBLEM TO BE SOLVED: To provide an artificial fertilization method for short-necked clams capable of improving productivity of short-necked clams.SOLUTION: Sperms 7a and eggs 7b are taken out from a male and a female of a parent short-necked clam 6 respectively, and the sperms 7a and the eggs 7b are suspended in sea water 9 in separate containers 1A and 1B to produce suspensions 8a and 8b. After the suspensions 8a and 8b are left still for a predetermined time, the respective suspensions 8a and 8b are transferred to a container 2 for agitation, and are forcibly agitated by an agitator 5. Then, air A is supplied to a liquid 10 in the container 2 for agitation to keep the liquid 10 in a state of being circulated. The sperms 7a and the eggs 7b in the liquid 10 are fertilized so that the fertilized egg gives birth to a larva 11.SELECTED DRAWING: Figure 2【課題】アサリの生産性を向上させることができるアサリの人工受精方法を提供する。【解決手段】アサリの母貝６の雄から精子７ａ、雌から卵子７ｂをそれぞれ取り出して、精子７ａと卵子７ｂとを別々の容器１Ａ、１Ｂ内の海水９に懸濁させて懸濁液８ａ、８ｂを製造し、これら懸濁液８ａ、８ｂを所定時間静置した後、それぞれの懸濁液８ａ、８ｂを混合用容器２に移して強制的に攪拌機５により攪拌し、その後、この混合用容器２内の液体１０に空気Ａを供給して液体１０を循環させた状態に維持し、液体１０内の精子７ａと卵子７ｂとを受精させて、その受精卵から幼生１１を誕生させる。【選択図】 図２
