This simple to use brine shrimp hatchery is ideal for the hobbyist, science fair student, teacher, or aquarist who treats their fish to the occasional live treat.  No aeration required! For a limited time, includes a three month supply (50 gram) of Grade A Great Salt Lake Brine Shrimp Eggs.

"Just wanted to send a quick note on how happy I am with your Brine Shrimp Hatchery Dish. The dish is performing as you stated and it works without a pump! I find the dish to be a perfect fit for my needs and very easy to use. Thank you also for the extra spirulina." J.L. Los Angeles

We first saw this brine shrimp egg hatchery in Kowloon, Hong Kong and were instantly intrigued by its strange shape. With some misgivings about the functionality of the "breeding dish," I brought it home and tried it. I was amazed at the results in 24 hours! With absolutely no aeration, air tubing, or heat, my yields were as good as if I had used a more elaborate set-up. With a premeasured charge of about 0.4 grams of dry cysts, the Hatchery Dish yielded over 100,000 baby brine shrimp. A particularly nice feature of the shallow, dish-like shape of the Hatchery is the naturally occurring separation of the newly hatched nauplii (baby brine shrimp) from shells and unhatched egg - resulting in a very clean harvest. No siphoning or net is required. This is truly a great product for hobbyists!

 

 

HATCHERY DISH INSTRUCTIONS

Instructions:  The Hatchery Dish provides the aquarium hobbyist with a simple, effective way to harvest and directly feed clean (i.e. without shell) quantities of newly-hatched, live baby brine shrimp (nauplii).

Required: You will need either aquarium salt, sea salt, or baking salt, along with clean tap water or distilled water and a separate one-liter or quart-sized container to prepare the hatching solution. You will also need a warm well-lit area where the Hatchery Dish can be left undisturbed for 24 hours. No aerator is required with the Dish. Because of the shallow depth of the water, there is sufficient oxygen exchange at the water surface.

Prepare Hatching Solution: In a separate container, dissolve 25 grams of salt (equal to one and two-thirds level tablespoons, or 5 level teaspoons of fine or medium grain salt) into one liter (approx. one quart) of fresh tap water or distilled water at room temperature (preferably 70⁰-80⁰F).

Set up Hatchery: Place the bottom portion or basin of the Hatchery Dish in a warm area with lighting where it can be left undisturbed for 24 hours. An overhead incandescent light is ideal for providing both light and extra warmth. Fill Dish with Hatching Solution to the fill-line indicated on the inside of basin. Place concentric white ring divider in center of Dish. Place mesh cup in center of Dish. Using the small spoon included with Dish, sprinkle one to two heaping spoonfuls of brine shrimp eggs (artemia cysts) on top of the water around the outermost area of the ring divider. Do not stir the eggs into the water. Carefully place lid on Dish. Position lid so that the mark (arrow) on lid is in the “closed” position. Let stand for 24-28 hours. Depending upon the room temperature, the brine shrimp should begin hatching in about 24 hours. 

Harvest: Nauplii are phototactic. As the brine shrimp begin to hatch, the nauplii will swim to the light in the center of the Dish. You can extract the nauplii from the Dish as they accumulate in the mesh sieve. It is common to harvest multiple times from the Dish in a 48-hour period.

Clean: When the supply of nauplii appears to be exhausted, dump the shell and remaining un-hatched egg and clean Dish with hot water. Periodically use a light chlorine solution to disinfect the Dish and other parts.
