Housefly (<i>Musca domestica</i>) Larvae Preparations after Removing the Hydrophobic Fraction Are Effective Alternatives to Fish Meal in Aquaculture Feed for Red Seabream (<i>Pagrus major</i>)
Insects are an attractive alternative to fish meal (FM) as a sustainable protein source in aquaculture feed that does not negatively impact the marine ecosystem. Despite housefly (<i>Musca domestica</i>) larvae having adequacy of amino acid profiles, they have sometimes been reported to...

Insects are an attractive alternative to fish meal (FM) as a sustainable protein source in aquaculture feed that does not negatively impact the marine ecosystem.
