TIPS AND TRICKS

Rock salt works well for me. One tablespoonful of salt to one liter of water gives me about 80 percent hatching rate. Using a hydrometer following the specific gravity recommended might add to the hatching efficiency.

Some recommend using an air stone but I don’t. The fine bubbles tend to minimize water circulation.

I also use the solution three times before creating a new one. I set up the brine one day apart to ensure a daily supply of hatchings. A syringe with a silicone hose for small hatchery can be used for a setup of less than 500 milliliters . For a bottle hatchery at least one liter big, a siphoning hose is recommended.

The water should drain using the siphon hose through the filter, leaving only the shrimp behind the flannel cloth. Be sure to place the silicone hose at the bottom of the bottle before siphoning. The empty shrimp shells should float to the surface of the bottle. If a light under the bottle is placed, the live shrimp should be drawn towards the light. The brine at the flannel will be ready for your hungry fishes. The fry can eat brine for several weeks, which can be slowly replaced with Tubifex or fine dried fish food.

Hatching brine shrimps for me is already an interesting activity in itself, just like changing the aquarium water. However, not everyone would understand how cleaning the tank brings joy.
