What lupins are used? Most have poisons. Thanks!
According to a research on Aquaculture Nutrition & Environmental Management published at the Department of Fisheries, Government of Western Australia website:
"The narrow-leaf sweet lupins Lupinus angustifolius, is the main species of lupin grown, though other varieties such as the yellow lupin (L. luteus) and white lupin (L. albus) are also grown. Each of the lupin species differ subtly in their composition. The removal of the seed coat to produce a kernel also alters the composition of the resultant kernel meal, which has considerable advantages over whole-seed meal when included in fish diets".
We'll publish any other information we can get on the matter, but we cordially invite our community members, especially those from Australia, to comment this issue in depth.
