Dean’s Fishroom Posted August 5, 2020 Share Posted August 5, 2020 (edited) Some do some don't, but here is why I rinse my newly hatched brine shrimp before feeding to fry. So in a tablespoon of brine shrimp eggs there approximately 420,000 to 450,000 brine shrimp eggs. I use eggs that are supposed to give a 90% hatch rate so let just say around 400,000 hatch in a little less that 2 liters of water. It is generally agreed upon that they hatch in 24-48 hours and I run my hatchers for 36 hours. Now I want you to think about this. . . baby brine shrimp hatch and start swimming about, they also more that likely start feeding on whatever exists in the water be it dead shrimp parts, decaying shells, etc. we know this because you can see growth right from the start. Well. . . if they start eating they also start peeing, pooping, excreting, whatever shrimp do. All this umm stuff is of course just bubbling around in the hatching water, and you want to dump it into your fry tanks? Just for the sake of 30 seconds of rinsing it off? My picture shows what the hatching water generally looks like after straining all the shrimp and shells out, pretty grungy right, and the saltwater ammonia test is way off the chart. Do you still want to just dump that into your fry tanks? Now just take a whiff of that hatching water, you still want to dump that in your fry tanks. I know that there are those on both sides of the benefits to rinse or not to rinse your newly hatched brine shrimp. I"m not on the fence with this, I'm firmly on the side of the fence that I always rinse my newly hatched baby brine shrimp before feeding. What if it makes the difference between having 90 fry surviving from a spawn or 300 fry surviving? I've found that sometimes in the fishroom it's just those few extra minutes here and there that produce the much better final results. Oh, and I can't imagine that any fish wants that shrimp pee, poop, or ammonia flavor on their first meals of their life.
