Got about 200 4-5" yellow perch pr heading out any ideas on improving my methods. It will be airport to airport. Tried breather bags big (50 fish) and small (5 fish) had ok results unless bag was spined. Regular thicker bags small (20 fish) about 50/50 water/o2. Would it be better to do the huge ml bags and pack like a 100 in each bag? Or have a hundred small bags? I usually throw bag buddies shipping additive.
