Ngôn ngữ:

Thông tin chủ yếu	Gopalakrishnan, A. and A.G. Ponniah, 2000
Các chú thích	Found in backwaters. Crustaceans were the most important prey items. Feeding specificity underwent moderate ontogenetic changes. The diet of fingerlings (<10 cm) mainly crustaceans was reduced with increasing size (Ref. 78456). Adult consumed a broad variety of food items including the bones of frogs and terrestrial insects (Ref. 78456). Increase in feeding intensity was noted in Lake Vembanad, south India from September to December (post-monsoon) with a reduced rate from May to July (monsoon) (Ref. 78456).
