Food for thought - what a fish needs in the way of nutrition has been established over eons through natural selection (genetics and adaptation) on natural foods. Pelleted feeding is more efficient for the fish as it does not have to expend energy on capture (recall bioenergetics - growth = food in less energy used). The real question is what do the fish need and can it be made economically.


I know someone who is -- or was? -- pushing the idea of using insect larvae to replace some of the fish protein in pellets. He said this would be cheaper and more humane than killing fish, especially as fish become scarcer, though he did admit that 100 percent larvae was not as effective as 100 percent fish. Still, his research indicated that half to two-thirds of the fish protein could be replaced without ill effect on growth & health.
