Breeding and acquisition
丰年虾 繁殖及采集
Brine shrimp is bisexual breeding adult male has a pair of brine shrimp catch, hugging female brine shrimp back. Together constantly swim. Can birth Ovoviviparous nauplii or direct ovulation. In direct ovulation, the eggs and egg summer and winter eggs and two kinds of output quickly after the eggs hatch into summer nauplii in the water, the eggs directly with the birth mother of viviparous nauplii basically the same. The winter egg was resting eggs, generally have a relatively large change in the brine shrimp survival environment, such as cooling, the proportion rising sea levels (that is, water evaporation, increasing salinity), lack of food and other chemical drug stimulation, brine shrimp eggs will be produced sleep. Resting eggs with thick egg shell, can endure harsh environmental conditions, generally not directly hatch in the water, you need to go through a diapause period, returned to the water to hatch, the majority of brine shrimp eggs for the floating of sleep collecting and convenient. Brine shrimp populations is to use this way to withstand harsh environments, the future generations in the form of dormant eggs to protect them, to return to normal after hatching environment. We buy goods in the form of brine shrimp eggs, is dormant eggs. Resting eggs stored under cool, dry conditions, can survive for about five years, when it re-enters the room temperature, seawater, or in a damp environment to absorb the moisture, will stimulate the metabolic activity of the shell of the embryo begins to enter the incubation process, and ultimately hatched, becoming nauplii. Newly hatched brine shrimp nauplii with yolk sac, do not feeding within a day, the body of nutrients consumed by the growth of the nutritional value from the point of view, about a day later to be reduced by about 20%. If you want to nauplii fed small fish or large fish larvae in the hatching process to harvest feeding as soon as possible. Nauplii under appropriate conditions, after raising about ten days, you can reach the length of the adult brine shrimp, about 1 cm above the female, male 0.7 cm.

Brine shrimp - Durable eggs
Brine shrimp eggs hatching process lasting durable brine shrimp egg quality is good or bad, can be judged according to the following methods: (A) at a temperature of 25 ℃, salinity thirty-five thousandths under test 1 hatching: namely (nauplii per gram of durable eggs are hatched) / (total durable eggs per gram) × 100%. 2 eggs per gram of the total weight of durable larvae hatch. 3 hatching efficiency: namely, the number of nauplii per gram of durable eggs are hatched. 4 nauplii first appeared incubation time required. Time required 5.90% nauplii hatched. 6 hatched larvae dry weight of the individual and the individual level of calories. (B) the naked eye: 30 times magnifying glass view of sand, salt, broken shells and feathers, the amount of debris. (C) nauplii size. (D) the nutritional value of nauplii. Method durable shelled eggs After the brine shrimp eggs durable hard-shell larvae swallowed, can block the digestive tract, causing the death of seedlings, it is necessary to avoid doping nauplii egg shells, put seeds in the pool as possible. To reduce the impact of the egg shell, the following procedure can be shelled. 1 Durable egg first with seawater immersion for half an hour. 2 eggs with durable cloth collection, to the water. 3. Adding cold as a fraction of 15 ~ 20 ℃ bleach. 4. Cheer 5 to 7 minutes, or, as the change from brown eggshell orange. 5 was collected by filtration, fresh water. 6 grams per liter in and join Na2S2O33. 7 cheer 5 to 7 minutes. 8 was collected by filtration, fresh water rinse. 9 according to the usual method of hatching eggs. After shelled treatment, durable hard shell eggs are dissolved, so seedlings can avoid swallowing hard shell, resulting in death.

详细孵化方法
Brine shrimp in particular salinity water in order to wake up to their resting eggs hatch water preparation involved in the hatching success of the hatch when the desired salinity of natural seawater only half to one-third one only, so the easiest way to access to natural sea water and fresh water mixing ratio of 1:1 or 1:2 can. Can not be obtained in natural seawater, but also commercially available artificial sea salt according to the recommended dose of the first dubbed artificial seawater and freshwater mix. In addition, we can see from the foregoing conditions, salinity also contains 10 to 15 grams of salt per liter, so we can add 10 to 15 grams of salt per liter of fresh water to use, and generally concentrated laundry detergent the attached measuring spoons, each key can be roughly fitted about 40 to 45 grams of salt, so the two-liter PET bottles converted incubator need to add about eight full spoonful of salt can be. Hatching brine method of preparation, if possible, the best hydrometer to test its salinity, to ensure that the proportion maintained between 1.01 to 1.02.

Summary
丰年虾 总结
Brine shrimp can own a pet. Specialized feeding brine shrimp to sell products, including brine shrimp bait. If you do not want to spend so much money to buy those stuff to keep, you can get hold of their own mug, creating a water brine shrimp need artificial seawater or add a little coarse salt magnesium. Brine shrimp grown in seawater salinity higher than those waters, lakes, etc. is usually uncertain. After somehow mug cheer and sunshine for at least five hours a day, but when the summer sun is too hot to be careful not to cook shrimp soup! Such as algae grow thick and then the brine shrimp eggs into the water, about one to two days on hatched. The brine shrimp eat algae grow, when in good condition can be self-reproduction, you can feed the fish with live brine shrimp can be maintained for a long time. However, when cultured algae Chlorella needed to add nutrients, can put some vegetables or algae cultivation agent.
