Where applicable,substitute insect proteins for otherwise marketable fishery based proteins in modern aquaculture systems.
This idea would help reduce the "net loss in usable proteins" idea and to my knowledge of the subject be not only a more sustainable source of protein, but be the natural one for many species of fishes. Tilapia for instance are vegetarian fishes, in the sense that they eat algae and aufwuchs found naturally in their environment and gain their proteins mainly from incidental consumption of invertebrates, both aquatic and terrestrial. So I propose that feeds, such as the flake and pellet feeds given to aquacultured fishes like Tilapia spp. and Trout spp. use inset based proteins instead of fish based proteins.
I have done some research on this and do know that there is now a study underway in Spain studying the efficacy of such an idea. I am also aware that due to the various mad cow scares over the years, the only animal proteins allowed in any feeds for animals destined to be consumed by humans as stipulated by the FDA (and their equivalents in many countries) are to be animal proteins derived only from fishes.
Anyways just a thought of how we could reduce at least one reduction fishery and possibly produce better tasting, more sustainable, and hopefully more cost effective farmed fish.
Please let me know what you think and help me trouble-shoot this idea. I have been testing it on my own in aquaria, but not for very long.
