Is the frozen krill that we buy in flat packs cooked? In raw shrimp the they are grey with clear flesh. the krill car pink/orange with white flesh. they look to be cooked. If this is true I can get small cooked salad shrimp very cheap.
I would imagine that these small shrimp would rot quickly. They are probably cooked right after unloading and then frozen for shipment to different companies.
However, you may have to take into consideration the costs associated with harvesting them. There is probably a bit more work involved in harvesting krill as opposed to crickets or the like.
