Abstract
The invention provides an artificial propagation method of native fish in the Chenghai Lake, which is characterized by comprising the following steps of: (1) parent fish selection: selecting native fish deriving from the Chenghai Lake; (2) parent fish training: training the parent fish in a natural ecological environment simulating the Chenghai Lake; (3) propagation: building a side slope of 35-45 DEG by using stone blocks on one side of a pool, paving sands on the side slope, and progagating through methods of natural egg laying, spawning hastening by using medicine and artificial fertilization in sequence; (4) hatching: putting fish eggs in a hatching pool for hatching; (5) fry culturing: starting feeding the fish fries 3-4 days after hatching, and culturing the fish fries in a fry poolafter breeding the fries 2 weeks; and (6) adult fish cultivation: cultivating the fish fries after the fish fried grow to 3-5 cm. The native fish in the Chenghai Lake can be subjected to scale production by using the artificial propagation method.
Description
Technical field:
The present invention relates to a Chenghai Lake indigenous fish artificial breeding methods, especially Chenghai whitefish (common name: white fish) Anabarilius? Liui? Chenghaiensis? He, Cheng Hai Erythroculter (common name: Pressure fish) Erythroculter? Mongolicus? Elongates? He? Et? Liu, Round kiss Xenocypris (common name: Red-winged fish) Distoechodon? tumirostr? is? Peters artificial breeding methods.
Background technology:
Cheng Haihu is one of lake, nine great plateau, Yunnan Province, is positioned at Yongsheng middle part, Lijiang City, Yunnan Province, and the indigenous fish in the lake is enjoyed great prestige the surrounding area with its unique quality, delicious local flavor.Typical indigenous fish Cheng Hai whitefish (common name: white fish) Anabarilius? Liui? Chenghaiensis? He, Cheng Hai Erythroculter (common name: Pressure fish) Erythroculter? Mongolicus? Elongates? He? Et? Liu, Yuan kiss Xenocypris (common name: Red-winged fish ) Distoechodon? tumirostr? is? Peters and other 20 kinds.In recent years; Along with increasing of resident along the lake and enterprise, caused pollution in various degree for the water source of Cheng Haihu, the growing environment of indigenous fish in serious threat; Add alien species its fish-egg of eating in a large number; Cause the indigenous fish in the Cheng Haihu to fall sharply in a large number, the part kind is endangered, and the protection of strengthening Cheng Hai lake original inhabitants fish is also imperative.But, still there is not the successful report of the artificial breeding journey indigenous fish in sea at present because the physiological habit of Cheng Hai lake original inhabitants fish receives the influence of extraneous natural environment bigger.
Summary of the invention:
The present invention aims to provide a Chenghai Lake indigenous fish artificial breeding methods, especially Chenghai whitefish, Cheng Hai Erythroculter, round snout Xenocypris artificial breeding methods.
The present invention includes parent population source, the handling of parent population, breeding, hatching, fry rearing, adult fish culture is characterized in that:
1, broodstock Source: derived from Chenghai Lake, including Cheng Hai whitefish (common name: white fish) Anabariliusliui? Chenghaiensis? He, Cheng Hai Erythroculter (common name: Pressure fish) Erythroculter? Mongolicuselongates? He? Et? Liu, Yuan kiss Xenocypris (common name: Red-winged fish) Distoechodon? tumirostr? is? Peters.
2, the handling of parent population: parent population is put into Cheng Haishui and mountain spring mountain and in the pond, raises after by mass ratio 1: 0.2～0.4 mixed, and the pH value of water is 7.5～9, and water temperature is 14 ℃～28 ℃, in the pond, is provided with the stone pit hole and causes the nature spray.
3, breeding: be built into the side slope of 35～45 degree in the side in pond with stone, spread sand on the side slope, use the stimulation by running water parent population, parent population is laid eggs on the stone of flowing water or sand; Fail the parent population that on the stone of flowing water or sand, lays eggs; Carry out putting into the pond in female 2: 1 ratios of hero after medicine is hastened parturition, the pond water temperature remains on 18 ℃～26 ℃, and the depth of water is between 0.5～1 meter; Put into branch, brown skin, stone in the pond, fish-egg can produce on branch, brown skin, stone; The parent population that residue is not laid eggs breeds with the spermatozoa insemination method.
4, hatching: fish-egg is put into the hatchery, and the hatching water temperature is 18 ℃～26 ℃, and the depth of water is 30～80 centimetres, and water velocity is 5 meters～8 meters/minute, and the oxygen content amount of water body is 4mg/L～8mg/L.
5, the cultivation of fry: seedling hatches out after 3～4 days and begins the food of throwing something and feeding, and throws something and feeds 5～8 times in 1st, keep water in the water body flow and the water oxygen content amount reaches 8mg/L, seedling culture is put into the fry pond after 2 weeks, every mu of density 5～100,000 tails.
6, adult fish culture: put into pond culture behind fry rearing to 3～5 centimetre, the pond water temperature is 14 ℃～28 ℃, and the depth of water is 1～3 meter, and the water quality pH value is 7.5～9, and cultivation density is 5000～10000 tail/mus, keeps the oxygen content amount of water, the artificial spray of making.
Using the present invention, Cheng whitefish fertilization rate of up to 70% survival rate of 50% hatching; Cheng Hai Erythroculter fertilization rate of up to 80% survival rate of 60% hatching; Yuan kiss Xenocypris fertilization rate of 90%, hatching survival rate of 70%; through artificial breeding can make Chenghai Lake indigenous fish scale production.
