| 内容記述 | ３種の単細胞微細藻類を餌料として，アコヤガイ幼生を付着時期まで飼育し，その生長を観察した。与えた餌料は 1) Monochrysis lutheri，2) Chaetoceros calcitrans および 3) Chlorella sp. で，それらをそれぞれ単独あるいは混合して投与した。最も生長のよかった餌料区の付着期までの生長量で比較すると Monochrysis 単独あるいは混合した区の生長がよく，次いで Chaetoceros，Chlorella の順であった。細胞膜を有する後二者特に Chlorella を与えた区の生長がよくないのは，生長の模様などから推察して，幼生初期の段階で消化吸収能力に欠けていることに帰因すると思われた。 | |||||

| 内容記述 | Larvae of the Japanese pearl oyster (Pinctada fucata (Gould)) were fed with 3 species of micro-algae to determine their relative value as foods. The algae used were the naked flagellate Monochrysis lutheri, a diatom Chaetoceros calcitrans and a green algae Chlorella sp. (Table I). Twenty thousand D-shaped larvae were reared in a 2 l glass beaker in a water bath in a dark room. Aged sea water used in all cultures was filtered (Ca. 5 μ), treated by ultra-violet light and received about 100 ppm of antibiotic kanamycin. The culture water was replaced every second day by straining off the larvae with a plankton net. The water was enriched either with a single species of food or with a mixture of different species. The foods were supplied at a concentration of 104 cells per ml (1st-12th day) or 2x 104 cells per ml (13th-25th or 26th day). A mixture of different foods consisted of approximately equal number of each species. The algal cells were not separated from their culture medium (Tables II, III) when added to the larval culture. The larvae were sampled for growth measurement every 4th day. Each culture was finished when the larvae with the best growth rate in a series of experiments reached the full grown stage. The results of experiments are shown in Figs. 1-5. There is a difference in the results between Experiment 1 and 2. This may be due to a difference in the larval broods, the quality of sea water and physiological state of the food algae. These effects are difficult to reduced. A mixture of Monochrysis lutheri and Chaetoceros calcitrans provided slightly better growth rate than did any of these foods singly or any other mixture of foods. Monochrysis and Chaetoceros were also shown to be the good single foods for larvae. The larvae fed with Chlorella sp. showed the poorest growth rate among larvae in all cultures. It was estimated from the growth curve that, although the Japanese pearl oyster larva at the first developmental stage cannot utilize algae such as Chlorella with a cell wall, these foods can be fed and digested by the older larvae. I wish to express my sincere thanks to Dr. P. Walne, Fisheries Experiment Station, Conway, U. K., for his correction of this English manuscript. |
