초록
한국산 rotifer, B. plicatilis, S-type를 대상으로 식물부유생물, 농축 Chlorella 및 효모류에 대한 내구란 생산과 먹이 종류에 따라 생산된 내구란의 부화율을 조사하였다. 4 종류(Chlorella ellipsoidea, Nannochloris oculata, Tetraselmis suecica, Pavlova lutheri) 가운데 N. oculata는 3,760개/20 ml로 가장 많은 내구란을 생산하였다. 그러나 식물부유생물 종류에 따른 부화율의 유의적인 차이는 없었다. 9 종류의 농축먹이(유지효모, 빵효모, 두 종류의 해수산 농축 냉장 Chlorella, 해수산 냉동 Chlorella, 냉동 해수산 Chlorella (
Dietary values of phytoplanktons, concentrated Chlorella and commercial yeasts were investigated for the resting egg production of the Korean rotifer, B. plioatilis S-type. The hatching rate of the resting egg of the rotifer fed on different diets was also studied. The highest production of the resting egg was 3,760 eggs/20 ml with N. oculata. However, the hatching rate was not significant among 4 phytoplankton species. The highest production of resting eggs among 9 diet groups (
