摘要：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 analyzed quantitatively and descriptively. The results showed that the gut length ratio of yellow rasbora ranged from 0.53 to 0.81. Gut histological showed no stomach structure with the relative height of the villi in the middle intestine approaching 0.5. Feed composition in the foregut showed that 60% was animal, and the rest were detritus and microalgae. Measurement of protease activity at foregut showed that no acidic protease activity but found alkaline proteases. In conclusion, yellow rasbora was an omnivorous fish with a short intestine and no functioning stomach.
