Brine Shrimp saltwater outdoor Pond Build Log

I haven’t done a brine shrimp pond in years and I decided now that I’m hatching baby brine shrimp every day, it was time to grow some adults.

first I had to get rid of the duckweed from the pond. I left in the muck and little bits of plants. The salt will kill them and fuel some green water once the sun hits it for a few days. 
 

It always amazes me how much salt goes into saltwater. I did 50 cups of salt for 100 gallons. This instant ocean salt I had already. I don’t like it as much as fritz salts but for a brine shrimp pond it’ll do. 
 

I’m running a usb air pump with a never clog air stone mostly to just mix the salt and keep the water from getting too stagnant. I’ve run the brine ponds before with no airation and I find it runs a little cleaner it seems with air.

In my opinion it's a myth that only baby brine are nutritious. Otherwise frozen brine shrimp wouldn't exist. baby brine become less nutritious as they grow, so say you hatch them out and they are 24 hours old. at 48 hours, they've only lost nutrients cause they haven't eaten.. This is where the myth comes from. if you feed/grow brine shrimp they are as nutritious as anything else.  A case can be made that baby brine are very packed with nutrients. However it takes a ton of brine shrimp to feed big fish. I plan to feed these to adult apistos, african cichlids, platies, guppies, mollies. I plan to feed them green water, yeast, maybe some crushed up flake into power and such. They're filter feeders so will eat whatever is suspended in the water.

That’s good to know!  Thanks!  
 

How big do these get?  I’m assuming too big for fry.

dude this is awesome! now that its really booming after 30 days and the numbers are only going up by thr day, at about what day do you think youll need to start feeding? or do you think the foliage breaking down will sustain until the winter?

 

also this is the nerd in me tryna maximize outcomes, do you think there are things you could feed to maybe gut load them in a sense? like feed them nicer things than foliage waste or do you think it wouldn't really matter much for the nutritional transfer from brine to fish.

You can definitely maximize here, but for me I like it to be super easy. I sprinkle fry food and green water in there to feed them.

I raised adult brine shrimp last fall and winter inside in a 10g with small spong filter mostly for the fun of it. My first batch crashed and my second batch just did ok. I made salt water with Ocean Nutrition and fed sprilina powder.

They weren't doing much reproduction so I just turned off the light when we went to visit family for almost two weeks but left it running. When I got back they were doing great! I fed much more lightly and also stirred up the settled spirlina ocasionaly while toping off for evaporation to maintain the specific gravity.

They still didn't really get going enough to be much of a regular harvest so I finally broke it back down. Glad I did it though.
