Abstract

The invention discloses a hephaestus fuliginosus and scortum barcoo outbreeding technology, and belongs to the field of cultivation. The hephaestus fuliginosus and scortum barcoo outbreeding technology comprises the following steps: parent breeding-parent cultivating-parent selecting->artificial spawning->male and female parent temporary rearing in different pools for awaiting delivery artificial insemination->fertilization spawn cleaning->fertilization spawn counting->artificial incubation->fish fry hatching->fish fry cultivating. After parent fish is put into a pool, insecticide, antibiosis and antimycotic serial measures are taken to prevent and treat fish diseases, the fish is fed by wheat malt, bottom material ameliorants are adopted to improve the bottom, HCG+ efficient No.3 fish odinagogue is adopted to hasten parturition, after the odinagogue is injected, the female and male parents are temporarily bred in a pool-dividing mode for awaiting delivery, the outbreeding is carried out on hephaestus fuliginosus and scortum barcoo, and the total performance index reaches 80-100% of the oxytocin spawning rate, 80-100% of the fertilization rate and 30-95% of the fertilization spawn hatchability.

Description

Fresh water black porgy and jewel perch outbreeding technology
Technical field
Fresh water black porgy of the present invention and jewel perch outbreeding technology belong to cultivation field.
Background technology
The thick lip Ruo of fresh water black porgy formal name used at school Ji La (Hephaestus fu1iginosus) is that ((Terapontidae) Ruo Ji La belongs to (Hephaestus) fish to Perciformes in Percifomes) La section.Fresh water black porgy originates in Australian northern Tully River (Da1y River) water system, is local famous-brand and high-quality economic fish.But because of with the shortcomings such as size differentiation is serious in group fish, affected its popularization cultivation, China has been difficult to find its track in most of provinces at present.The high Ti Ge of jewel perch formal name used at school La (Scortum barcoo), ((Terapontidae) Ge La belongs to (Scortum) fish in Percifomes) La section to belong to Perciformes.Being Endemic fish in Australian Murray and Tully River, is one of famous and precious fish of having long enjoyed a good reputation of locality, on international fishery market, enjoys a very good reputation.This fishing gear has crude feed tolerance, and growth is fast, output is high, without the advantage such as stinging between flesh, and the major defect of jewel perch is that body fat content is too high, make transportation of live fish more difficult, the automatic control of ingesting of jewel perch is poor, in breeding process, often because overfeeding causes the accident that makes fish extremely full, occurs.
The ovum diameter of fresh water black porgy is larger, and proportion is large more many than water, and toughness belongs to sticky demersal egg; The ovum diameter of jewel perch is less, after water suction, proportion and water approach, very easily in water, suspend, both difference is very big, the distant hybridization breeding of fish is to utilize the crossbreeding of carrying out between the fish that the blood relationship of taxon more than kind is far away, after hybridization, obtain the expansion of gene diversity, thereby the possibility of selection is provided for obtaining excellent genes.But the fish intermolecular hybrid that blood relationship is too far away, successfully probability is low on the one hand, the appearance of rare merit on the other hand, also rare employing in production practices.From the successful probability of current fish hybridization breeding achievement Lai Kan, section's intermolecular hybrid both domestic and external far below between belonging to or between planting, the hybridization of subspecies, few especially for section's intermolecular hybrid filial generation of fish production.Between planting in the genus of fish, subspecies distant hybridization has long history, also produced a large amount of elite hybrids, in production practices, be widely used.Although the intergeneric cross of fish not as good as between planting, inter-subspecies hybrid amount is many, its heterotic effect much larger than between planting, inter-subspecies hybrid.
Summary of the invention
The object of the present invention is to provide a kind ofly in order to overcome the shortcoming of fresh water black porgy and jewel perch, obtain more fresh water black porgy and the jewel perch outbreeding technology of high-quality fish, make it hybridize the new fish kind that to have concurrently fresh water black porgy and jewel perch advantage.
The object of the invention is to reach by following measures:
Fresh water black porgy and jewel perch outbreeding technology are as follows:
Parent's seed selection → parent culture → parent selection → artificial induced spawning → parent male and female minute pond is supported temporarily and is treated the hatch → fry rearing of product → artificial insemination → cleaning insemination ovum → insemination ovum counting → artificial incubation → fry.
Parent culture technical measures comprises that 1. parent population adopts desinsection, antibiotic, antimycotic series of measures preventing and curing of fish disease after entering the pool, and the puffing material of the crude protein content 34% of 2. throwing something and feeding, alleviates water pollution.3. the wheat malt of throwing something and feeding, promotes gonad development.4. with immersible pump bath, stimulate, further promote gonad development.5. up to 6 o'clock next day, open aerator oxygenation every day 23, guarantee not occur the event generation that anoxic affects gonad development.6. at the bottom of within 20 days, using substrate modifier as polyoxy, change the clean treasured of king or the end and change the end, create the good water body environment of a parent population existence.
Artificial induced spawning, adopts ocyodinic to hasten parturition, and ocyodinic is HCG(human chorionic gonadtropin) add efficient No. 3 ocyodinics for fish (maleic acid DOM DOM+ salmon releasing hormone analog S-GnRH-A).
After adopting injection ocyodinic, parent population male and female minute pond is supported and is waited to produce temporarily.
The present invention carries out fresh water black porgy and jewel perch outbreeding, and indicators of overall performance reaches the spawning rate 80-100% that hastens parturition,, insemination rate 80-100%, insemination egg hatching rate 30-95%.
Embodiment
Embodiment 1:
Idiographic flow is as follows:
Parent's seed selection → parent culture → parent selection → artificial induced spawning → parent male and female minute pond is supported temporarily and is treated the hatch → fry rearing of product → artificial insemination → cleaning insemination ovum → insemination ovum counting → artificial incubation → fry.
1, parent's seed selection: select build straight, male fresh water black porgy and the female jewel perch that denumerable proterties is up to standard hybridizes, female fresh water black porgy and male jewel perch hybridize, and selecting body weight is the male parent of 0.75-1.25 kilogram and the female parent of body weight 1.5-1.75 kilogram.
2, parent culture: parent population adopts desinsection, antibiotic, antimycotic series of measures preventing and curing of fish disease after entering the pool, the throw something and feed puffing material of crude protein content 34%, alleviate water pollution, the wheat malt of throwing something and feeding, promotes gonad development, with immersible pump bath, stimulate, further promote gonad development, opened aerator oxygenation up to 6 o'clock next day every day 23, guarantees not occur the event generation that anoxic affects gonad development, regularly use substrate modifier to change the end, create the good water body environment of a parent population existence.
3, parent selects:
The female parent population selection criteria of fresh water black porgy is: belly is full, expands, soft flexible, and gonopore is micro-prominent, slightly kermesinus;
