Feeding intensity in relation to si

Feeding intensity in relation to size of fish: Observation on feeding intensity in relation to size of S. canaliculatus clearly indicated that as the fish grows in size, active feeding declined (Fig. 7). The fishes in 17-18 cm size group feed actively. The percentages of empty stomach increased from 0% (17-18 cm) to 77.8% (37-38 cm) as the size group of fish increased. Moderate and poor feeding was observed in all the size groups at varying percentages. Low feeding intensity in large-sized fish may be due to physiological stress associated with spawning (Zacharia, 2003).
