I have read that BSF larvae and worms are an excellent source of protein for tilapia, but contain too much fat, which can cause problems as the fish develop into adulthood (liver damage, breeding).
I'd like to be able to reduce the fat content of these livestock rations, as I am ardently against the use of fish meal, yet would like to achieve decent growth rates.
Has anyone attempted this with success?
I've read posts about a guy who tried chopping them up and boiling them, but wasn't able to render any fats from them.
Could an alternative simply be in not feeding the fish BSF larvae and worms too frequently and compensate with algae and duckweed?
