Instructions on how to hatch artemia larvae quickly at home

Along with the grass larvae, artermia larvae are considered to be the "last resort" to help breeders nurture betta fry successfully and develop their flock ... Artemia is the larvae often used to hatch fry above 10 days old. To take care of ornamental fish, we often have to hatch hatching artmia larvae and raise young fish. Artemia nauplii are a vital and nutritious food source for betta fry. This type of food is widely used mainly because of the amenities and benefits they provide.
- Depending on the amount of larvae of shrimp and fish, choose the amount of eggs to hatch for food; Normally every 1 gram of artemia eggs hatch in a liter of seawater. If sea water is not available, take 30 grams of granulated salt (without iodine) to dissolve 1 liter of water to incubate the eggs.
- Next, stir the artemia eggs into the brine and stir the aerators continuously. After 24 hours, artemia eggs hatch into larvae and are harvested as food for shrimp and fish larvae.
- How to harvest artemia nauplii: turn off the aerator and use the racquet to remove the supernatant (eggshell). The sunken part is the artemia larvae that are filtered out to feed the fish.

Detailed instruction on how to incubate artmia successfully at home:

Incubating artemia is very simple. Any cone-shaped device can be used to hatch an artemia. Ordinary objects such as a 2 liter bottle of mineral water are an ideal incubator. If you prefer hi-tech incubation, the online also sells a type of transparent incubator cone capacity of about 3.5 liters. Many Sally incubators are a hard rubber sole that a 2 liter bottle of mineral water can plug backwards into [Figure 7]. Again, almost everything is usable, but the bottom cone should be used to keep the water uniform and without dead spots. The aeration tube should be installed at the lowest point of the incubator and that is all done. [Figure 8]

Use brine to hatch the artemia. Wilkerson (1998) recommends the use of inexpensive granular salts with low salinity. Mix 2 teaspoons of granulated salt tea with 2 liters of tap water (chlorinated). When the salt dissolves, aerate about 1 hour and add nearly ¼ teaspoon of artemia eggs. Adequate aeration will result in high hatching rates and healthy larvae. Airstone should not be used, but rigid plastic tubes should be attached to the bottom of the incubator. Do not be afraid of strong aeration. Air bubbles can cause strong water disturbance. Once the eggs have hatched, they can be carried by air bubbles to the surface of the water and fly out, so reduce the amount of aeration. Make sure your aeration tank is illuminated on the first day and for the next 16-20 hours you can see the artemia larvae appear. The newly hatched larvae are very nutritious and can bring about fry immediately. The abdominal sac makes the larvae yellow. By the way, if you have clownfish you have to raise them with newly hatched larvae less than 30 hours because if you keep them longer the larvae will be too big for the fry to eat. If you store it after 24 hours, the nutrition bag will be consumed the next day; The larvae begin to eat and can be nourished with food containing special nutritional components.

Larvae harvest

When harvesting, simply stop aerating and let it sit for about 10 minutes to settle. Eggshell emerges from the surface while the larvae hatch together with the rotten egg. Because the larvae are attracted to the light, we use a flashlight to illuminate the center of the incubator to focus them in, then siphon tubes to suck out, or in commercial incubators, people can discharge. the valve at the bottom of the tank to remove the broken eggs and then discharge again to take the larvae to another tank. Another way to harvest artemia is to use a racquet (very small hole) to remove the eggshell from the surface. Then use a small siphon tube attached to a plastic tube (about 3 mm in diameter) to suck out the artemia larvae and raise young fish.
