| 内容記述 | On July 24, 1964, three pairs of the blind gobioid fish, Odontamblyopus rubicundus (HAMILTON), were collected from the tidal muddy flat on the coast of Isahaya Bay, Nagasaki Prefecture (Fig. 1). They were transported to the laboratory of Nagasaki University and there kept in an aquarium. On July 25, gonadotropic hormons, Synaholin and pituitaries of a fish, were injected and planted in the muscles of the tested fish, to induce the spawning, and Synaholin was supplementally injected on July 29 and August 2 (Table 1 and Table 2). After the first hormon-operation, each pair of the tested fish was enclosed in an earthen pipe, which was set on the aquarium-bottom as an artifical breeding-room. A pair of the tested fish (Fish Nos. 5, 6) spawned 300 eggs on Angust 1. The eggs consisting of 240 fertilizes eggs and 60 unfertilized eggs deposited on the inner wall of the earthen pipe. The fertilized eggs consisted of 40 normal eggs, abnormal agrippa eggs and other abnormal ones with inadquately expanded egg-membranes (Fig.2, 3). Abont 20,000 other discharged eggs consisting of fertilized eggs and unfertilized ones had already eaten by the male parent fish (Fish No. 5) when the spawning was recognized. The normal fertilized eggs were oval in shape, being 2.3～2.6mm in long axis and 0.6～0.7mm in short axis. The egg was demersal and possessed a boundle of adhesive filaments at the basal end of the eggmembrane. Eye-vesicles firstly appeared in the 12 hours old embryo (Fig. 2, F), and eye-balls appeared in 20 hours old and 26-myomere embryo (Fig. 2, I). The eyes of the embryo normally develobed along with the egg-development. The hatching took place 75 hours after the spawning at the water-temparature of 27.6～28.8℃. The newly hatched larva possessed normal eyes, a few melanophores and 32 myomeres, and was 3.4mm in total length (Fig. 2, M). | |||||||||

| 内容記述 | 日本産のめくらハゼの1種であるワラスボについて採卵実験を行った。長崎県諌早湾の天然生息場から1964年7月24日に採集した雌雄成魚3組を水槽で飼育し,それに性腺刺戟ホルモンを注入し,人工産卵室として土管を利用し,ホルモン処置魚をその土管内に閉じ込めておいたところ1組の雌雄魚が8月1日に産卵し,受精卵を土管の内壁に産み付けた.この産卵では放出卵のなかに未受精卵および逆子卵が多かった.また,大部分の放出卵は雄親魚が食べていた.受精卵は沈性付着卵で,卵膜は長径2.3mm,短径0.6～0.7mmの長なす状をなし,その基部に付着糸そうがある.産卵後12時間の胚体で眼胞が現われ,20時間後の胚体で眼球がみられ,その後卵発生が進むにしたがって正常な眼が形成される.ふ化時間は水温28℃で約75時間であった.ふ化直後の仔魚は正常に発達した眼をそなえ,全長3.3～3.5mmで,体には黒色素胞が少なく,その筋節数は9+23であった. | |||||||||
