Terrestrial insects as the main food for freshwater fish in Sungai Kerian tributaries: an implication on habitat conservation

The importance of terrestrial insects as food items for freshwater fish was studied by examining stomach contents of Devario regina (Fowler 1934) and its population parameters at canopied areas of selected tributaries of Sungai Kerian, in the northern state of Peninsular Malaysia. Ninety six percent...
