| 内容記述 | Larvae of red sea bream, Chrysophrys major, hatched from eggs were reared under laboratory conditions and their swimming and feeding behaviours were observed. Marine rotifer (Brachionus plicatilis), copepod (Tigriopus japonicus) and chopped meat of shellfish were employed in succession as food stuffs for the larvae and juveniles. Pantagraph was used to record the swimming passes of the larvae in the rearing aquaria, and the swimming speeds were calculated from the travelled distances and the required time. The active swimming of the larvae was observed to begin at the stage of oil globule absorption. An active feeding also began at the same phase. The swimming speed of the larvae was dependent mainly upon the age of larvae and the feeding conditions. Up to 20 days after hatching, swimming speed of about 50 cm/min. was recorded after feeding as well as before feeding. While, after 20 days old after hatching coinciding to the transition from post-larva to juvenile, the swimming speed and its difference in relation to the feeding condition increased remarkably. Consequently, it was considered that swimming behaviours was largely influenced by the abundance of available food and age of larva. | |||||

| 内容記述 | マダイ稚仔魚の成長に伴う行動の発達,特に游泳に関する発達を知るため通常の飼育条件下における観察を行い次のような結果が得られた。1)ふ化仔魚は開口するまではほとんど動かないが,卵黄吸収と相俟って急激に動きを開始し,油球吸収期以後は常時游泳する。これらの一連の行動は摂餌生態の変化に伴って起ると考えられる。2)稚仔魚の游泳速度は成育に伴って増加するが,特にふ化後20日頃から速度が増加し始め,30日頃には給餌前で200cm/min程度の速さになる。こうした機能の発達は稚仔魚の形態変化や生活様式のうつりかわりと関連していると考えられる。3)餌料密度と摂餌条件(空腹,満腹)は稚仔魚の游泳速度に強く影響し、また餌料密度が低下すると速度は増加する。そしてこの傾向は,一般に発育段階が進む程著しくなる。 | |||||
