Sorry to be so late to get on this thread. I have found unhatched
brine shrimp cysts can kill 3-spine sticklebacks but do not bother
other species of larvae. The sticklebacks seem to be unable to pass
the unhatched cysts through their digestive system. One can buy
really expensive de-capsulated brine shrimp eggs or go through a
nasty process (that I could email to you if you really wanted) of
taking the shells off yourself before hatching them. The best
solution is to be very careful when harvesting so as to not to
include any of the egg casings that are floating around. This is
probably too late to be of any service now but maybe in the future?
