Re: [Killietalk] hatching out brine shrimp

["Robert Goldstein" <rgoldstein at rjgacarolina_com>]

Timely question. I just dumped a half-used and old can of BBS cysts from 
Brine Shrimp Direct for a combination of reasons. This was the last, and the 
only bad one,  of a dozen cans that had given me pretty good hatches. The 
last can, for reasons I don't know (age? open in the freezer too long? 
random bad can?) was giving me bad hatches with partly hatched larvae or 
none at all. These would not separate. Normally, good separation means empty 
cysts floating when the filtered hatch is placed in a jar of fresh water, 
and pink shrimp on the bottom. Not in this case. Worse, when used as food, 
these partially hatched cysts created a fungal mess on the bottom, and worse 
yet, apparently poisoned the fry of various tetras and other fishes in 
different tanks. The fry would eat some of this, but mostly stayed thin and 
steadily died off. I finally threw in the towel (and threw away the can) and 
opened a new can (again from a case of a dozen) from another supplier 
(N.A.B.S. in Salt Lake City), resulting in a good, normal hatch. That ruled 
out the possibility that my hatch water was bad (I use recirculating, 
trickle-filtered sea water). This is not to denigrate Brine Shrimp Direct. 
I've had excellent results with them over the years. This was just a bad 
can, for whatever reason. Now with regard to an 8-oz package, I think this 
may be the source of the problem. In my experience, anything other than a 
vacuum-packed 15-oz metal can yields third rate, if any, hatches because 
nothing but a metal vacuum-packed can will keep out moisture.   - Bob
