looking for advice on using fish for larvae control

This year I hope to put gold fish in my water barrel in my garden, I won't be dipping from it unless we get our usual drought, but when it's used it'll have fishy-poo water in it, good for my garden, and I hope to keep the mosquitoes killed off rather than have the screening over the barrel. Will theyt be enough to kill off the mosquito larvae? Any thoughts? TIA
plant ID please?
