Abstract
The invention belongs to the technical field of raising gymnocypris przewalskii commercial fish, and in particular relates to a process for raising gymnocypris przewalskii in a net cage. The technical scheme comprises three steps, namely pond fingerling culture, net cage fingerling culture and net cage commercial fish raising, wherein during the pond fingerling culture, 1+ year gymnocypris przewalskii fingerling culture is completed; during the net cage fingerling culture, 2+ year gymnocypris przewalskii fingerling culture is completed; and during the net cage commercial fish raising, commercial fish raising is completed. The gymnocypris przewalskii fresh water artificial raising process is succeeded in net cage raising, can be used for enlarging the surviving and raising space for the gymnocypris przewalskii, provides popular gymnocypris przewalskii commodity which has rich nutrition and dedicate flesh for people, meets the diet and market requirement of people, and has huge marketing economical benefit and environment ecological benefit.
Description
One: technical field: the invention belongs to Gymnocypris prezewalskii marketable fish cultural technique field, be specifically related to a kind of Gymnocypris prezewalskii cage culture technology.
Two: background technology:
Gymnocypris prezewalskii＜hereinafter to be referred as naked carp〉be aquatic vertebrate unique in the Qinghai Lake, be in the core status of the Qinghai Lake ichthyornis symbiosis ecosystem.Qinghai Lake fish production at end of the fifties in last century initial stage of development, the quality of output and catches is all higher.The sixties, peak annual output reached 2.8 ten thousand tons, long 28.8 centimetres of catches average body, and the mean age was 10 ages; The annual production seventies drops to about 4000 tons gradually, long 26.9 centimetres of catches average body, 8 ages of mean age.Since the later stage seventies, because weather arid river course Lai Shui falls sharply, build a dam in the river course of mainly laying eggs in addition and dam, the spawning ground is destroyed, the quality of Qinghai Lake fish crop, catches is sharply descended, and the nineties, average annual output only was 2263 tons, long 24.0 centimetres of catches average body, mean age was 5 ages, and the decline of resource is fairly obvious.
From calendar year 2001 so far, Qinghai Lake is in the 4th time and the 5th time and educates fish period in the envelope lake comprehensively, forbids the sale of Gymnocypris przewalskii and goods thereof.Because Gymnocypris prezewalskii is nutritious, the meat exquisiteness is loved by the people, and therefore carrying out Gymnocypris prezewalskii propagates experiment work artificially, and huge market economy benefit and environmental ecological benefit are arranged.Because Gymnocypris prezewalskii is high and cold saltwater fish, it is very huge to propagate the test difficulty artificially, so also do not have the high and cold saltwater fish of Gymnocypris prezewalskii to propagate the technology of test artificially at present.
The applicant carried out Gymnocypris prezewalskii on a large scale and breeds when releasing from 2002, carry out Gymnocypris prezewalskii fresh water and propagate experiment work artificially, in reservoir cage culture, obtained success, expanded the Gymnocypris prezewalskii living space, Gymnocypris prezewalskii is the bright spot of our province aquatic products industry exploitation, also is the cool good fingerling of water body artificial fecundation of Qinghai-Tibet lake and northern China.
Three: summary of the invention
The objective of the invention is to carry out Gymnocypris prezewalskii fresh water and propagate experiment work artificially, in cage culture, obtained success, expand the Gymnocypris prezewalskii living space, for people provide a kind of nutritious, the meat exquisiteness, the Gymnocypris prezewalskii commodity that are loved by the people, to satisfy people's market demand, it has huge market economy benefit and environmental ecological benefit.
Its technical scheme is: its technological process is pond fry rearing, the net cage nurture of fish fingerlings, and the net cage marketable fish is cultured three parts.
1, pond fry rearing: from stand " crow young " fry of hatching of Gymnocypris prezewalskii artificial releasing, after the pond is cultivated 25-35 days with soya-bean milk, use the domestication of 0.8-1.2 millimeter particle diameter bait to rob food, each feeding is eaten up according to feeding last time amount and is as the criterion, the an amount of feeding volume that reduces after entering autumn, throw something and feed once noon every day in winter, strengthens feeding volume after the beginning of spring.To perpendicular year July, the fingerling specification can reach 8-12 centimetre, and finish 1 this moment
+The naked carp nurture of fish fingerlings stage in age.
2, net cage nurture of fish fingerlings:
(1) netting gear requires: the mesh specification decides 1 by the fry stocking size
+Age, the naked carp fingerling was with 0.2-0.6 centimetre of mesh, cage size 4-6 rice * 4-6 rice * 46 meter, area 16-36 rice
2
(2) put fingerling in a suitable place to breed: the time of putting in a suitable place to breed, putting fingerling in a suitable place to breed was 1 of preceding operation generation in the 6-7 month
+Age the naked carp fingerling.It is domestication's food grain feed, and fingerling physique stalwartness, anosis nothing are hindered, move about active.Potassium permanganate and 3-8% saline solution with 15-23ppm before the fingerling cartonning embathed 20～30 minutes, breeding density 1200-1500 tail/square metre.(3) feeding and management: the number of times of throwing something and feeding day is worked as water temperature at 15～20 ℃, day bait throwing in 3-5 time, and when water temperature is lower than 16 ℃, day bait throwing in 2～3 times.Daily ration of feeding is regulated according to water temperature, 1～March, water temperature was at 3～6.3 ℃, day feeding volume is the 0.8-1.2% of fish body weight, 4～June and 10～December water temperature at 6.5～16 ℃, day feeding volume is about the 1.6-2.4% of fish body weight, 7～September, water temperature was at 17～20 ℃, and a day feeding volume is the 2.0-3.0% of fish body weight.The adjusting of feeding volume should be regulated once every 15～20 days, concrete adjusting way is at random fishing for 25-35 tail fish with diddle-net every 15～20 days in net cage, it is long to measure its body, total length, weigh and calculate the average weight of fish, determine daily ration of feeding according to actual measurement net cage fish body weight.Feeding method is will calculate and divide that the bait that weighs up is artificial evenly to be dropped in the case at every turn, and is advisable with the migration of having enough of big portion fish, day 55-65% of bait total amount that throws something and feeds general morning every day, and 35-45% throws something and feeds afternoon.
To perpendicular year July, the fingerling specification can reach about the 65-75 gram.Finish 2 this moment
+The naked carp nurture of fish fingerlings stage in age.
3, the net cage marketable fish is cultured:
(1) branch mailbox:, should reduce density and add large cage mesh, 2 with the increase of fish body
+Age, naked carp fingerling usefulness mesh was 1.0-2.0 centimetre, breeding density 200-300 tail/square metre.
(2) tank-washer: the net cage attachment according to circumstances, the 1-2 month cleans once, guard box inside and outside water body exchange is unimpeded.When cleaning net cage, it is light that action is wanted, and avoids the fish body injured.
(3) feeding and management: be analogous to the feeding and management of nurture of fish fingerlings, but daily ration of feeding is brought up to the 3.5-4.5% of fish body weight.To in July, the 3rd, about fingerling specification 400-600 gram, reach commercial specification this moment, can catch to stay for a short time greatly, sells successively.
The present invention is that Gymnocypris prezewalskii fresh water is propagated technology artificially, in cage culture, obtained success, expand Gymnocypris prezewalskii existence and culture the space, for people provide a kind of nutritious, the meat exquisiteness, the Gymnocypris prezewalskii commodity that are loved by the people have satisfied people's diet and market demand, and it has huge market economy benefit and environmental ecological benefit.
