内容記述 | Adelie penguins were used as a biological sampler from late December 1995 to late January 1996 to study biological characteristics of euphausiids in Lutzow-Holm Bay, which is generally covered with fast sea-ice even in summer. Stomach contents and diving behavior of the penguins were examined. Euphausiids accounted for 73% of total wet weight of stomach contents, and fish 27%. Among euphausiids, Euphausia superba occupied 83%, and E. crystallorophias 17%. Females occupied 96% of the total number of E. superba, males only 4%. E. crystallorophias consisted of 73% females, 10% males and 17% juveniles. Adelie penguins might eat nutritionally superior female euphausiids selectively, and/or they could not catch male euphausiids which can swim faster. It was suggested that those individuals which dived deeper ate more euphausiids than fish, and larger E. superba. | |||||
