Examining contents of the stomach and intestine of sardine, Sardinia melanosticta, caught in the waters adjacent to Kyusyu, the author was able to clear up some points on feeding habit of sardine with reference to its growth.
The results are summarized a ?? follows:
1. The larval fish of 20-40mm. in body length fed on chiefly Oncaea sp., Microsetella sp., Lamellibranchia-larva, Gastropoda-larva, etc. but no Dia ?? om.
2. The young fish of 50-140mm in body length fed on both Copepoda and Diatom.
3. The fish larger than 150mm in body length fed on chie ?? ly such diatoms as Chaetoceros sp., Bacteriastrum sp. and Tha ?? a ?? siothrix sp. etc.
4. The sardine over about 50mm. in body length seems to be able to take such microplank. ton a ?? Diatom.
