昆虫形成用于许多水生动物天然食物来源。 This and the presence of chitinase makes insect meals a logical alternative to fish meal in the formulation of aquaculture diets. Insect meals have also been shown to allow for enriching through dietary intake. Of particular interest has been the use of black soldier fly larvae. This article reviews the life history and potential of black soldier fly larval meal to replace fishmeal used in fish diets.

Integrated multi-trophic aquaculture is a flexible concept, on which many variations can be developed and should not be viewed as confined to open-water, marine systems. Freshwater integrated multi-trophic aquaculture, perhaps better known as aquaponics, applies the same principles as those used in marine integrated multi-trophic systems. In particular, using plants to reduce phosphorus (and other nutrient) levels in effluents can help farmers meet water quality guidelines and prevent eutrophication in the environment.

Originating from South America the apple snail species of Pomacea, commonly referred to as golden apple snail, was imported into Vietnam from 1985 to 1988 with the intention of raising it for human consumption. Not long after that, the introduced snails quickly spread to most freshwater ecosystems of the country. This review examines the current status and history of apple snail introduction in Vietnam, and the various control and management measures used to cope with snail infestations.
