Description

Water stabilising arrangement is bred to eel

Technical Field

The utility model relates to an eel breeds relevant technical field, especially relates to an eel breeds water stabilising arrangement.

Background

Eel, another name: eel, white eel, steamed bread, Japanese eel. Eel is a generic term for species belonging to the order anguillales. Also called eel, is a fish with the appearance similar to long-strip snakelike shape and has the basic characteristics of fish. Furthermore, eel has migration characteristics similar to salmon. Eel fishes are similar to snakes but have no scales and are generally produced in salt and fresh water boundary sea areas.

The fry of eel is about 6 cm long and 0.1 g heavy, but its head is narrow, body is high, thin and transparent like common leafy eel, so it is called "willow-leaf fish". The body fluid of the floating cage is almost the same as that of seawater, so that the floating cage can float and convey along with ocean current for a long distance with labor saving. In the general case of the seaside, which floats back to black tide from the spawning site and flows back to taiwan again, for half a year, the eel line is transformed into a slim and transparent eel line, also called glass fish, only one month before arriving at the shore. Therefore, fishermen can catch the eel line going to the river by using the handmade-fork net on the coast near the river mouth to sell the eel line to farmers in 12-1 month each year. After the farmers buy the eel, the color of the eel slowly appears, and the eel becomes yellow young eel and silver adult eel.

The eel fry cultivation is a production process for cultivating eel fries with more than 10 g. In this stage, three different types of ponds such as a first-stage pond, a second-stage pond and a third-stage pond are required to be cultivated. The eel breeding is the foundation of adult eel breeding, and the quantity and quality of the eel breeding directly influence the quality of adult eel breeding. Therefore, to develop eel breeding, first, the breeding of eel fries must be performed.

In order to ensure the smooth operation of eel fry cultivation, the following production links are required to be grabbed in addition to all the preparation operations.

First, eel fry stocking density

The breeding mode is different, and the stocking density of the eel fries is also different. The stocking density of the water-stop pond is 150-300 g/m, and the stocking density of the running water pond is preferably 500-1000 g/m. The low-density stocking can grow fast and the survival rate is high.

Second, eel fry stocking time

Because the eel fries can formally begin to eat and grow at the water temperature of more than 15 ℃, the eel fries are cultured in the open air pond, and the stocking is more suitable when the natural water temperature reaches more than 13 ℃. Therefore, after the eel fries are temporarily bred for a short time and adapt to the environment, the eel fries can be eaten and domesticated when the water temperature rises. The breeding time of the eel fries in Guangdong and Fujian is about 3 months.

In the eel breeding field with heating condition or warm water supply, the breeding time of eel fries is advanced as much as possible, so that the breeding period can be prolonged, and the yield and quality of eel fries can be improved.

Thirdly, the count and weighing of the eel fry

In order to control the stocking density of the eel fries, the eel fries are required to be counted during stocking, and the stocking weight, specification and mantissa of each primary pond are calculated. The specific method comprises the following steps: firstly, slightly stirring the eel fries in the net cage uniformly, then randomly sampling for 2-4 times, weighing 50 g each time, putting the eel fries in the eel fry fishing sea, and counting the number of the eel fries in a small bowl or a small spoon, and then calculating the average specification. Finally, the number of eel fry per kilogram is calculated, thereby obtaining the average specification.

Fourth, the adaptation of eel fry to environment

The eel fry is in a fatigue state after long-distance transportation, and the difference between the temperature in the fry transportation container and the temperature of pond water is too large, in particular to a heating cultivation pond, so an adaptation process is needed, and the concrete method comprises the following steps: placing the eel fry box beside the pool, gradually spraying the eel fry box with pool water, and placing the eel fry box into a net cage which is placed in the pool in advance when the temperature of the eel fry is close to the temperature of the pool water and is not different from the temperature of the pool water by 5 ℃; if the nylon bags are used for oxygen-charging transportation, the nylon bags and the eel fries can be placed in the pool firstly, and then the bags are removed when the temperature of the bags is close to the temperature of the water in the pool, and the eel fries are placed in the net cage. The eel fries are temporarily cultured for 30 minutes to 1 hour, an aerator is started, dead fries and dirt are skimmed after normal activities, and the eel fries are weighed, counted and placed into each eel fry culture pond.

Sterilizing eel fry

The eel fry is delicate and easy to scratch during the processes of catching, temporary rearing and transportation to infect saprolegnia and bacterial diseases. Therefore, sterilization is necessary in stocking. The disinfection method is medicated bath, one is medicated bath with a container, and the other is medicated bath sprayed in the whole pool.

The disinfection step and the method are as follows: when using the container for medicated bath, the operation is generally carried out in a large water vat, so the container is also called as bath. The specific method comprises the steps of firstly containing 300-400 kg of clear water in a cylinder, then dissolving the clear water in a small amount of water according to the dosage proportion of the medicines, pouring the water into the cylinder, starting an aerator for aeration, continuously stirring the water to uniformly distribute the liquid medicine, weighing about 5 kg of eel fry and , immersing the eel fry and the into the liquid medicine, bathing the eel fry for 10-15 minutes, and taking out the eel fry for stocking. The whole pool is sprayed with the medicine bath at night, the medicine is directly sprayed in the first-level pool after being dissolved, and the aerator is started to stir water, so that the medicine liquid is uniformly distributed.

Disinfection drugs and concentration: the commonly used medicines mainly include methylene blue, salt and the like.

And (3) disinfection time: the medicated bath in the container is carried out before the eel fries are put into the pool; the whole pool is splashed and disinfected in the evening of the day after the eel fries are put into the pool.

Aiming at the characteristic that the requirement of eel on water quality condition is high, eel aquaculture water needs to be further purified, disinfected and heated to be stable and then is injected into a fish pond, in the prior art, the treatment of the aquaculture water generally needs to be carried out for settling and purifying in a reservoir with a large occupied area, then the settled aquaculture water is slowly injected into the pond after being purified, sterilized and disinfected, in order to ensure that the aquaculture water has a certain temperature, an eel culture shed is always kept stable by heating in a season with low temperature, the temperature of the eel pond is kept at a certain value by a heat transfer mode, and if the specific heat capacity of the water is high, a large amount of energy needs to be consumed to maintain the value when the temperature of the aquaculture water is stable, so that the change cannot occur, meanwhile, the occupied area of the reservoir in the prior art is large, and the capital investment of the aquaculture farm is increased.
