Abstract: Fishmeal is the main component of feed in aquaculture and accounts for 40 to 60% of total protein in aquaculture and monogastric feeds. The alternative feed resources of insects and other edible invertebrates are a sustainable solution for animal feed but are classified in little known sources. They do not at the moment imply a feed competition with human nutrition. Among the most targeted invertebrates are the larvae of flies or maggots because of the ease of production, the duration of the production cycle and the importance of their biomass. The maggot meal has nutritional qualities comparable to fish meal, soy and contains many other conventional nitrogenous materials. The chemical composition of edible insects in generaly and maggots in particulary are similar or even better than those of conventional food ingredients and their use in fish feed induces good zootechnical performance. The consequences of this alternative mode of animal feeding are minimal and can be mitigated by the reasoned choice of the production substrates, the environment of their production and the processes of pre-processing into food ingredients comparable to fish. Its production makes it possible to recycle organic waste and consequently the management of the environment. Its insertion in fish feed is strongly recommended. The present work aims to summarize the studies on the biology and ecology of maggots, different production techniques maggots, their nutritional value and finally the various forms in which they are administered by fish.
