Adult Black soldier fly (Hermetia illucens).
Australian consumers love fish and seafood with consumption doubling over the last 10 years, and expected to continue to grow. However, most aquaculture species are fed, at least in part, on fishmeal made from wild caught fish, which is not only unsustainable, but also a major factor limiting increased production. Meal made from insect larvae has been proposed as an alternative. Insects are high in protein and fat, can be reared on waste products and are part of the natural diet of some farmed fish species. This article reviews an Australian study that examines the potential use of vegetable wastes to grow insect larvae, which can then be used in aquaculture and aquaponic feeds.
