Abstract
The invention discloses an eel breeding method. The eel breeding method comprises the following steps of (1) selecting a pond, (2) pre-handling the pond, (3) establishing the ecology of the pond, (4) selecting eel fry, (5) placing the eel fry in the pond, (6) preparing feed, (7) throwing feed into the pond, (8) monitoring the enology and (9) catching eels. By the adoption of the eel breeding method, the eel survival rate is increased, the eel growth period is shortened, and it is guaranteed that the eels are delicious.
Description
Technical field
The present invention relates to fishery cultivating field, relate in particular to the cultural method of a kind of yellow eel.
Background technology
Yellow eel has another name called swamp eel, its fine and tender taste, and delicious flavour, spur is few, good friend's rich in protein, yellow eel also has important medicinal, has tonifying Qi, enriches blood, anti-inflammatory, the effect such as dispel rheumatism.The wild resource of yellow eel is limited, and along with people's living standard improves, also increasing to the demand of yellow eel, wild fishing for is difficult to meet the need of market, and so just need to propagate artificially yellow eel.People have explored the cultural method of a lot of cultivation yellow eels in recent years, and due to yellow eel, biological engineering not yet completes, and artificial large-scale farming exists a lot of difficulties.Thereby cause the survival rate of yellow eel not high, growth rate is slow.
In addition, in the process of cultivation, the selection in cultivation place, the preparation of bait, the input of bait, be all to affect the key factor that yellow eel grows up.But in actual breeding process, few people can take into account these factors.Therefore cultivation yellow eel is not out that survival rate is not high, is exactly that meat is not delicious, is difficult to reach requirement.
Summary of the invention
Based on this, the not high and poky problem for survival rate in above-mentioned eel cultivation process, is necessary to propose a kind of cultural method that can improve yellow eel survival rate, shorten the yellow eel of its growth cycle and guarantee yellow eel delicious meat.
Technical scheme of the present invention is: the cultural method of a kind of yellow eel, comprises the following steps:
(1) select pond: select water quality good, pollution-free and cannot not have dryly a pond at water source, detect mud composition in pond, select to be applicable to the mud environment of yellow eel growth, after completing, selection, at pond water inlet and water outlet, gauze is set, and several flood discharge passages are set, and flood discharge passway arranges gauze;
(2) pond pretreatment: remove unnecessary mud in pond, make the mud degree of depth remain on 18 cm-22cm, arrange fence around pond, pond is carried out disinfection with quicklime, sterilized and thoroughly changed water once afterwards;
(3) pond is ecological builds: in pond, throw in earthworm and river snail, and plantation pasture and water, make it through 25 days-30 days self-sows, make pasture and water reach 75%-80% to the area coverage in pond;
(4) eel seedling is selected: fish for eel seedling at natural water area, select anosis, the harmless and Individual Size eel seedling at 70 tails/g-90 tail/g, pre-prepd culture pond cultivation 5 days-7 days;
(5) eel seedling is put in a suitable place to breed: put the front saline solution that is 5%-6% by concentration in a suitable place to breed eel seedling is embathed 15 minutes, then according to the density of 60 tails/m2, eel seedling is put into net cage, put water temperature in process in a suitable place to breed and remain at 28 DEG C-30 DEG C, PH value remains on 6.5-7.2;
(6) bait preparation: by 20-24 parts of dried earthworms, 40-45 parts of ripe soybean meals, 2-5 parts of blood meals, 65-70 parts, vinegar grain powder, 40-60 parts, rice bran, 12-14 parts, brown sugar and 3-6 parts of mixing of calcium dihydrogen phosphate, mix thoroughly;
(7) bait is thrown in: according to the quantity of earthworm in pond and river snail, throw in bait every day 1-3 times, each bait throwing in weight is 3%-4% of yellow eel body weight;
(8) ecological monitoring: regularly yellow eel is surveyed sample, regularly throw in disinfecting drug simultaneously to pond, throw in after disinfecting drug a few hours, change the water in pond, in real time water quality is monitored in breeding process;
(9) yellow eel is fished for: after cultivation a year and a half, place bait and fish in fishpot, fishpot mesh size is slightly less than ripe yellow eel size.
In an embodiment, eel seedling is selected in step therein, and culture pond is cement pit, lays mud at the bottom of pond, and eel seedling is put into culture pond with the density of 60 tails/m2, uses earthworm feeding in breeding process.
In an embodiment, eel seedling is put in a suitable place to breed in step therein, lays the pipeline that has venthole at the bottom of pond, and pipeline connects oxygen supply equipment, is pond oxygen supply.
In an embodiment, eel seedling is put in a suitable place to breed in step therein, the long 5m of net cage, wide 4m, high 1m, and net cage above water is 40cm, and underwater portion is 60cm, and net cage mesh size is slightly less than eel seedling size.
In an embodiment, eel seedling is put in a suitable place to breed in step therein, and the thermometer and the liquid level gauge that are respectively used to monitoring temperature, liquid level are set in pond, and pond arranges several the suction pumps that are connected with external water source around.
Therein in an embodiment, in bait preparation process, composition is specially 5 parts of 24 parts of dried earthworms, 43 parts of ripe soybean meals, 3 parts of blood meals, 68 parts, vinegar grain powder, 50 parts, rice bran, 13 parts, brown sugar and calcium dihydrogen phosphates.
The invention has the beneficial effects as follows:
(1) each step of eel cultivation is all passed through meticulous design and monitoring, and the yellow eel survival rate that cultivates out through these steps is high, growth cycle shortens relatively, meanwhile, ensures the deliciousness of its meat;
(2) at pond water inlet and water outlet, gauze is set, its object is to prevent that yellow eel from escaping; Several flood discharge passages are set, can be at Flooding, in the not strong situation of the delivery port flood carrying capacity in pond, carry out flood discharge;
(3) with quicklime, the pond after selecting is carried out disinfection, before eel cultivation, remove bacterium and harmful microorganism in a part of pond;
(4) in pond, throw in earthworm and river snail, the object of doing is like this to provide food for yellow eel; Plantation pasture and water are in order to keep the ecotope in pond, to keep the sun off, and ensure water temperature;
(5) setting of culture pond, is specifically designed to the pre-cultivation to eel seedling, and the object of this design is that the eel seedling to selecting further observes, and within the time of 5 days-7 days, can have further understanding to the quality of eel seedling; Facilitate the enforcement of subsequent step;
(6) water temperature in the pond monitored of thermometer, real-time controls water temperature, ensures the growing environment of yellow eel; Liquid level gauge and water pump are used in conjunction with, and in pond, water level is not good enough, when not dry water source goes wrong, can supplement timely water source;
(7) object of ecological monitoring is the growth track of real-time understanding yellow eel, ensures, in developmental process, great disease and large-area death not to occur.
