Providing quality fish feed became a prime aim of every aquaculturist. Though fish feed devours around 50% of the production cost, yet it plays the pivotal role in the production and yield outcome (Mzengereza et al., 2014). With the increase in demand, the price of feed increased simultaneously. One main reason for the rise in the cost price of fish feed is due to the rise in demand of fish meal which remains the core of the protein supply of the feed. The demand for fish meal is not just increasing but the supply of it is also dwindling with stagnating marine catches and alternative use of it for livestock and human consumption (Fasakin et al., 1999). So, the quest for possible alternative protein sources to replace (complete/partial) fish meal in the feed became paramount (Magouz et al., 2008). As animal protein sources are mostly expensive International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 07 (2018) Journal homepage: http://www.ijcmas.com Fish feed plays an important role in the growth of the aquaculture industry. Use of plant protein source in the feed industry has been in practice for various advantages such as sustainability, availability, cost effectiveness etc. Terrestrial plant leaves of turi, drumstick, ipil-ipil, alfalfa, mulberry, sweet potato, cassava, cucumber, squash, broad bean, papaya, white cowpea, green mung-bean, jackfruit, mexican fire plant, cocoyam, black jack, banana, akee etc. and aquatic plant leaves of azolla, water hyacinth, duckweeds, water lettuce, Indian stargrass, white snow flake, duck lettuce, bur-reed, 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 is use as direct feed (in case of herbivorous fishes), supplementary or partial replacement to fish meal in formulation of fish feed. The paper is an attempt to make extensive review on potential use of various plant leaves as ingredient in fish feed industry.
