Length ratio, histological structure, feed composition, and enzyme activity in the gut of yellow rasbora (Rasbora lateristriata Blkr.)

A study of the ratio of gut length, histological structure, feed composition, and enzyme activity in the foregut had carried out to determine the feed category of yellow rasbora. The study used a survey method with sampling in the Banjaran River, Banyumas, Central Java. The research data had analyze...
