Artemia are nodular crustaceans, which are used as food for aquarium fish of medium size, including near-bottom fish. Crayfish are good because they are suitable for breeding at home.
Artemia is rather unpretentious, therefore, having bought larvae (nauplii) in a store, you can grow fish food at home and delete this item from the list of costs.
Artemia – micro crustacean, used as fish feed
Artemia adults reach a length of 1.8 mm. They can feed the fish of medium size, while the larvae are suitable for feeding the young of almost all species of fish. It is necessary to take into account that the nauplii are held in bright places.
When frozen, they sink to the bottom, so catfish and barbs will be suitable as feed.
It is easy to keep eggs: they remain suitable for feeding and for breeding for a long time. The main condition that must be met, so that later it turned out to withdraw from the eggs of an adult individual – absolute dryness.
When moisture enters the cysts do not hibernate and begin to dwindle. It is best to store them in a sealed bag in the refrigerator.
There are several ways to breed Artemia crustaceans. At home, you can use any. They are similar, but have some features.
Even a beginner aquarist can cope with the cultivation of nauplii artemia at home.
Artemia can be diluted in several ways.
You can use a simple way, especially if the experience of breeding is small. It is necessary to prepare the most favorable environment for the eggs, so that the larvae hatch out of them.. This will require:
- half-liter jar with a lid;
- pure water;
- two plastic tubes;
On a teaspoon (without a slide) of eggs you will need 0.5 liters of water, in which you will need to dilute 20 g of table salt, then pour the future larvae there. The jar with this content needs to be closed with a lid in which 2 holes are made for plastic tubes (tubes should fit tightly).
One tube should reach the bottom, the second should not even reach the surface of the water. A sprayer should be put on the immersed end of the long tube, and a compressor should be put on the second end. It is necessary for mixing eggs.
The second tube serves to exhaust air. At a temperature of 24−25 degrees crustaceans ripen in 36−40 hours.
To collect crustaceans, you need to turn off the compressor and wait until they settle to the bottom. It takes about 5 minutes.
Then you need to drain the contents of the jar through a dense fabric so that the water spills out and the hatched crustaceans remain on the fabric.

- The percentage of release of crustaceans from eggs is usually small.
- It is impossible to completely clear the resulting feed from the shells, and they are bad for the health of the fry that can eat them.
Artemia nauplii can be diluted in two cans at intervals of one day (or two, but then three cans will be needed), and the food will be on hand at all times. It is necessary to take into account that it takes more time to grow adult crustaceans.
Before hatching, you need to soak the dry eggs in a 5% solution of salt for half an hour, then rinse them under the tap. After that, they are ready to be placed in a kind of incubator.
Artemia eggs should be soaked in salt before hatching.
The incubator is done like this:
- The 3-liter can is filled with water at 2/3. It is important that there is no chlorine in the water, so you need to use separated.
- In this water, dissolve 3 tablespoons of salt and place in it any floating alga, and pour a teaspoon of washed eggs into it.
- In the jar you need to lower the hose of the microcompressor with a spray. The air flow must be so strong that the eggs do not settle on the bottom.
- It remains to make round-the-clock lighting and put a thermometer in the jar. At a temperature of 20 degrees the crustaceans will hatch in two days, at 28 degrees – in a day. It is recommended to remove them at the same temperature used in the aquarium so that the Artemia can live longer.
For catching crustaceans it is advised to use a hose from a dropper, which can drain water through a dense fabric. When the amount of Artemia accumulated on the fabric is sufficient for feeding the fish, the salted salt water should be poured back into the jar.
In order for the hatched crustaceans to live for several days, good aeration is required. They cannot live in fresh water. In order for Artemia to grow to adulthood for feeding large fish, you need to put a jar of salt water in the sun, where algae would grow.
You can add there orange peel, then the crustaceans will grow and even multiply, because the algae serve them as food.
Besides, to feed Artemia at home you need “green” water or dry mix. Suitable water is obtained if you drain a little from the aquarium and hold it for a couple of days in the sun, and the dry mixture is made from yeast, flour, soy powder and egg yolk.
The amount of feed needs to be determined empirically so that it does not contaminate the water.
If you plan to breed crustaceans for a long time, then you can create for them a separate small aquarium. On average, they live 3 months, the larvae mature on day 8 (they feed on their own 12 hours after hatching).
Offspring in the amount of 300 eggs give every 4 days, And this is quite enough to constantly have at home food for aquarium fish.
