Abstract
The invention discloses a kind of breeding methods for hybridizing mandarin fish.It includes the following steps：A, it selects the sexually matured spot mandarin fish caught from field and sticks up mouth fish, two kinds of fishes are respectively put into respective parent's culture pond and are cultivated；B, it cultivates after 6-8 days latter two fishes reach the critical point of sexual gland maturation and carries out drug injection, human chorionic gonadtropin, heat after 6-8 hour, squeezes out mother's fish egg respectively and the progress of male milt is in vitro fertilization；C, hatchery is put it under 16-20 DEG C of water temperature, and dissolved oxygen 5-6mg/L is hatched after 30 hours.After adopting with the aforedescribed process, two kinds of fishes are respectively put into parent's culture pond according to respective concrete property to cultivate, by reasonable drug injection and fertilization of arranging in pairs or groups after culture, finally complete hatching, thus two kinds of entirely different fishes of original living environment unified cultivation has dexterously been subjected to, disease is greatly reduced, cultivation success rate is improved and improves meat feeling.
Description
Technical field
The present invention relates to a kind of breeding method of nursery, specifically a kind of breeding method for hybridizing mandarin fish.
Background technique
Spot mandarin fish is a kind of cold water fingerling, sticks up the fingerling that mouth fish is the Yangtze river basin, since the attribute of two kinds of fingerlings differs widely,
Therefore in the prior art spot mandarin fish and Mandarin fish fish can not together with cultivate, for spot mandarin fish, breeding process compares naturally, so
And for sticking up for mouth fish, due to the characteristic of its kind, when using artificial breeding, disease can be very serious, and cultivation success rate is very
Low, meat feeling is also very poor.
Summary of the invention
The technical problem to be solved in the present invention is to provide one kind can reduce disease, improves cultivation success rate and improves meat
The breeding method of the hybridization mandarin fish of texture.
In order to solve the above-mentioned technical problem, the breeding method of hybridization mandarin fish of the invention, includes the following steps：
A, it selects the sexually matured spot mandarin fish caught from field and sticks up mouth fish, two kinds of fishes are respectively put into respective parent's culture pond and are carried out
It cultivates, culture density is 4-6 tail/cubic meter, dissolved oxygen 5-8mg/L；
B, it cultivates after 6-8 days latter two fishes reach the critical point of sexual gland maturation and carries out drug injection, human chorionic gonadtropin, 6-
Heat after 8 hours, squeezes out female fish egg respectively and the progress of male milt is in vitro fertilization；
C, hatchery is put it under 16-20 DEG C of water temperature, and dissolved oxygen 5-6mg/L is hatched after 30 hours.
The spot mandarin fish is cultivated under 16-17 DEG C of water temperature, and the frequency of water circulating filter is 2-3 times/day in culture pond.
Described to stick up mouth fish and cultivate under 18-20 DEG C of water temperature, the frequency of water circulating filter is 2-3 times/day in culture pond.
The number of the drug injection is primary.
During the female fish egg of the extrusion and male milt, the ratio of male fish and female fish is 1：2.
In the step B, the injection volume of drug injection is 0.1-0.3 mg/kg.
After adopting with the aforedescribed process, two kinds of fishes are respectively put into parent's culture pond according to respective concrete property and are cultivated,
By reasonable drug injection and fertilization of arranging in pairs or groups after culture, hatching is finally completed, it is thus that original living environment is entirely different
Two kinds of fishes have dexterously carried out unified cultivation, greatly reduce disease, improve cultivation success rate and improve meat feeling.
Specific embodiment
With reference to embodiment, the breeding method of hybridization mandarin fish of the invention is described in further detail.
Embodiment one：

The frequency of filtering is 2-3 times/day, sticks up mouth fish and cultivates under 18-20 DEG C of water temperature, and the frequency of water circulating filter is 2- in culture pond
3 times/day；
B, it cultivates after 6 days latter two fishes reach the critical point of sexual gland maturation and carries out drug injection, human chorionic gonadtropin is injected
Amount is 0.1 mg/kg, and the number of drug injection is primary, heat after 6 hours, squeezes out female fish egg respectively and male milt carries out
In vitro fertilization, during squeezing out female fish egg and male milt, the ratio of male fish and female fish is 1：2.
C, hatchery is put it under 16 DEG C of water temperature, and dissolved oxygen 5mg/L is hatched after 30 hours.
Embodiment two：
The breeding method of the hybridization mandarin fish of the present embodiment, includes the following steps：
A, it selects the sexually matured spot mandarin fish caught from field and sticks up mouth fish, two kinds of fishes are respectively put into respective parent's culture pond and are carried out
It cultivates, culture density is 5 tails/cubic meter, and dissolved oxygen 6mg/L is cultivated under the water temperature that 16 DEG C of spot mandarin fish, water circulating filter in culture pond
Frequency is 2 times/day, sticks up mouth fish and cultivates under 19 DEG C of water temperature, and the frequency of water circulating filter is 3 times/day in culture pond；
B, it cultivates after 6-8 days latter two fishes reach the critical point of sexual gland maturation and carries out drug injection, human chorionic gonadtropin is infused
The amount of penetrating be 0.2 mg/kg, the number of drug injection be primary, heat after 7 hours, respectively squeeze out mother fish egg and male milt into
Row is in vitro fertilization, and during squeezing out female fish egg and male milt, the ratio of male fish and female fish is 1：2.
