Abstract: The aquaculture sector is well known to feed the human population since time immemorial. Fish feed plays an important role in the growth and development of the aquaculture industry. The use of non-conventional plant protein sources in the feed industry has been in practice for various advantages like sustainability, availability, cost-effectiveness, etc. Numerous plant leaves of Moringa, Sesbania, Leucaena leucocephala, alfalfa, Medicago sativa, Ipomoea sp., cassava, cucumber, squash, Carica papaya, white cowpea, green mung-bean, jackfruit, Mexican fire plant, cocoyam, black jack, banana, etc. and aquatic plant leaves of azolla, water hyacinth, duckweeds, water lettuce, Indian star grass, duck lettuce, water fern, etc. have been used in the fish feed industry. They are used in the form of fresh and raw, dried, powdered, cooked, fermented, concentrates, etc. It can be used directly in the feed (in case of herbivorous fishes), supplementary or partial replacement to fish meal in the aqua feed formulation. The paper is an attempt to study and analyse the nutrient composition (crude protein, ether extract and crude fibre) of different plant sources that can be a potential replacer of conventional feed ingredient such as de-oiled rice bran and fishmeal. For this purpose the leaves or samples were collected from different places and analysis of proximate composition was done using procedures of AOAC (2005).
