There are many fry bred this year, and I have been using shrimp seedlings in the previous year, and I have to hatch shrimp every day, but there is no way to stabilize it. Some time ago moved, the place is bigger, I think every day to engage in a good year shrimp thief tired (in fact, lazy). So start pouring flea, so now share with you the breeding experience of the flea.
The hydra is a small crustacean belonging to the phylum arthropods, crustaceans, and ceratosa. Called fish worms. Water fleas are small, about 2 mm long, light flesh red, and live in fresh water. Water fleas contain a large amount of protein in the body, up to 40%-60% of their own dry weight. Protein contains all the amino acids needed for fish growth. It has been reported that protein bait can only increase the metabolic intensity of goldfish by 20% to 30%, while goldfish can increase the metabolic intensity by 100% if they are fully fed to flea. The body fat content of water fleas is also very high, and goldfish will increase their fullness after swallowing. Water fleas are also very rich in carbohydrates, calcium, and vitamins. Water fleas are used as bait to raise goldfish, and their nutritional value is unmatched by other granular baits.
1. Water flea source
Water fleas have no specific growth environment restrictions, different species have different requirements for water temperature, as long as it is not a sword flea, other species are more feasible, in fact, the sword flea only about 40% of the types of fish do not like to eat. Sword water fleas will have barbs, and small fry will get stuck when eaten. It depends on the local climate. You can find him in the fields, fish ponds, wastewater ponds, it is best to bring your own glare flashlight when the weather is bad, if the sun is strong, you can not use it. Water fleas, like other insects, "put out fires". When you look at the surface of the water, there will naturally be white particles, and small insects with a diameter of 1-2 MM will jump in the water. Their shape and swimming style can be clearly seen with the naked eye. It is generally easy to collect, and some friends say that early morning faiths will concentrate on the surface of the water. In good weather, flea also move 1-10 cm below the water surface. They can be caught with a variety of tools, such as their own net made of stockings, or some teaching biological collection nets. In a little laziness, go straight to TB it.
Second, the problem of breeding water fleas after returning home
Breeding is very simple, the preparation tools are as follows: large to the pool, smaller than the Coke bottle can be used as a breeding vessel, collection tools and wild tools can be used, in fact, I think the dropper is OK. At present, the more popular indoor culture methods are green water culture method and yeast culture method. Of course, it is also possible to feed yeast fish without yeast, and our purpose is simple, to fill the water with food of flea - a variety of beneficial single-celled organisms. Including algae, yeast, and lactic acid bacteria are also OK. It is more convenient to use yeast, and a small packet of yeast powder under 2 yuan in supermarkets is enough to burst several cylinders. Let's introduce them separately:
1, green water aquaculture, is to cultivate green water, cultivate green water can be taken directly to the fish pond, can also be cultivated by themselves. Self-cultivation is recommended because fish ponds everywhere contain a lot of other microorganisms. The simplest way to cultivate yourself is to use fish tank wastewater + liquid fertilizer (base fertilizer is OK) + your own urine. Leave in the sun for a few days. Many people know this method and do not introduce it much. You can also go directly to buy some spirulina back to cultivate, spirulina is relatively easy to erupt. The advantage of this method of cultured water fleas is that it is not necessary to clean the flea tank frequently, and only need to add green water regularly.
2, yeast culture, yeast culture is also a very common method. Go to the supermarket to buy a small packet of yeast powder, about 2 yuan or less. Go home and take warm water (about 30-40 degrees) with a small amount of latent bubbles, which can be shaken to accelerate the dissolution of yeast (strictly speaking, it is not called dissolution... ), and then put the yeast liquid into the flea tank. If the density of the flea tank is high, someone will directly put it, and the effect is the same. As for the size of the amount of stocking, it cannot be generalized, but depends on the water quality of the flea tank and the base number of water fleas. Generally speaking, it is best to grasp the amount from small to large, and grasp it yourself. If you use a Coke bottle, do not exceed a spoonful of plastic sticks of that kind of purified coffee. If the amount of yeast is not much, the water can still see the bottom, the flea tank will not appear deposited, you can change the water every three days, if you are lazy to change the water can also add water, to at least increase or replace 1/5 of the original water is wonderful, and then there is no effect. The more water changes and tank cleaning, the better, and maintaining adequate food and good water quality are the two major conditions for flea bursting tanks. I tried to be lazy and did not clean up the sediment in the tank, and the result was that the tank was overturned, and the water also emitted a sour smell and was unhygienic. Moreover, the reproduction rate of water fleas is extremely wide. There are several reasons for the observation: too many bacteria in the water are hypoxic (can be solved with oxygen, but I do not), the sediment will stick to the flea to make him stop moving and die, and the water temperature is also one of the effects, but it is not as big as the previous two points. Simple summary of the key: yeast foot, frequent water change.
3, you can use yogurt, eel powder instead of yeast for feeding, not to say, with yeast a truth, but also will breed a lot of deposits. The amount of yogurt is best dropped as a unit, and it is easy to form a protein oil film when there is more water surface, and the water fleas will be hypoxic.
The above three methods can be mixed, and an appropriate amount of organic matter can be stocked when carrying out various breeding methods. Stinky to, fragrant to Japanese tofu can be. The amount of stocking is based on its own water quality and density, from small to large.
Iii. Deepen discussions
Water fleas are an insect that is easy to keep, but we mainly have to be lazy, and water fleas often take no less energy than hatching shrimp. Now the main discussion is from how to use limited energy to maximize the power (in fact, want to be lazy. Huh). I have just begun to contact, but the article has climbed a lot. At least Daddy's water flea articles have been read, they have a lot of quirky methods, I do not advocate such a toss, in fact, raising water fleas is to figure out convenient and cheap, so troublesome if it is not as good as the shrimp on the harvest year. The most troublesome thing about raising water fleas to burst the cylinder is to ensure water quality, and this is the most and most hated thing for lazy people such as me, even the fish have not had time to change the water, and every two or three days to change the water for the water flea is somewhat psychologically unbalanced.
Biochemical cotton full of yogurt
Here's a little trick for you
Because yeast or other organic matter will have sediment when it is put down, and there will be a thick oil film on the surface of the water. Xiaobian tried a large number of apple snails and a few shrimp to deal with. The first week of water fleas burst the cylinder, the effect is remarkable, the second week apple snail began to burst the cylinder, because the water flea at night when there is no light will lie on the bottom of the tank, apple snail army to extinguish the water fleas.
You can put a small amount of aquatic grass, you can also put a small amount of shrimp, clear the algae on the wall of the tank, shrimp is also organic matter.
Yeast liquid is also troublesome to add every day, and it is easy to spoil water. With that kind of small hole of sponge (a bit like a hole-like biochemical cotton, but the hole is much smaller, biochemical cotton is not suitable), fully adsorbed the yeast liquid, and then the sponge that sucked the yeast liquid was put into the flea tank, after that, the sediment in the tank was greatly reduced, the water quality was good, and the food was sufficient, because in the case of insufficient yeast in the water, it would overflow from the sponge, and the flea also regarded the sponge as a canteen.
Usually, the green water of the fish tank should not be wasted and directly poured into it, but the dirty things underground should not be poured into it.
Water flea seedlings have one more advantage than the shrimp in the harvest year, the shrimp can not eat the water will be bad, and the water fleas do not have to worry, many small fry can not eat the big water fleas, it does not matter, the big water fleas can also stay in the fish tank to purify the water quality.
Note that blue-type fighting fish will increase redness when eating water fleas, which contain a lot of chlorophycoidin, and chlorophycoidin is reddish.
