Effect of biotic and abiotic factors in feeding activity in teleost fish: A review

Abstract

Aquaculture is the fastest growing food sector in the world, which provide food, nutrition, income and livelihoods to millions of people worldwide. Production of aquatic animals from aquaculture in 2014 amounted to 73.8 MMT, with an estimated worth of US$160.2 billion. With increasing population, the demand of the food will increase and aquaculture has the potential to meet the increasing demand. Fish feed is one of the most expensive elements needed for fish culture. Feed intake can have effects on the overall culture cost and it could result in the deterioration of water quality. This review gives insights on the biotic and abiotic factor’s effect on the feed intake of teleost fishes.
