Feeds still represent the largest expense for many aquaculture operations. At the same time, they are a critical component of the production as it has the potential to improve feed and economic conversion ratio, growth, survival, egg quality, size variation and other key parameters. Wild populations of forage fish will not be able to satisfy the growing demand for fish meal, a main ingredient in feeds, and thus novel alternative meals are being researched, developed and implemented to reduce fish meal inclusion while maintaining optimum production performances. Insect meal is gaining a considerable amount of attention as a potential alternative protein source in feeds. The insect that is of interest in this proposal is the black soldier fly (Hermetia illucens). Already being commercially produced in the USA, France, Germany and China to name a few, the larvae of this insect allows for greater protein production per area than other protein systems, requires little not no added water, feeds on a wide variety of organic materials ranging from plant to protein waste and trimmings and animal manure, and can be produced in a closed and indoor system with complete control over its life stages. Research on black soldier fly larvae meal inclusion in feeds has been carried out for tilapia (Oreochromis spp.), catfish (Ictalurus punctatus & Pelteobagrus fulvidraco), Atlantic salmon (Salmo salar), Pacific white shrimp (Litopenaeus vannamei), turbot (Psetta maxima), European seabass (Dicentrarchus labrax), barramundi (Lates calcarifer), rainbow trout (Oncorhynchus mykiss), omega perch (Therapon barcoo), Jian carp (Cyprinus carpio) and gilthead seabream (Sparus aurata). Additional key research has been done to increase the levels of omega-3 fatty acids in the meal by feeding fish offal (Oncorhynchus mykiss) and brown algae (Ascophyllum nodosum) to the larvae. In this paper we intend to summarize the current status of black soldier fly larvae (Hermetia illucens) meal inclusion in aquaculture feeds and its effects on production performances.
