Could Fish Skin Become Belize’s Next Big Business? What if the part of the fish some people throw away could become the next source of income for Belizean families? “I have a patent to transform fish skins into valuable leather,” Luna said. It all starts, she says, from “fish skin that was previously discarded”. “All that skin goes to waste after a while because of the fillet and whatever they do with it, and as a fisher myself, I learned to turn the fish skin into leather, and now I have a short business idea,” she said.
