Description

The artificial breeding of Hunan Nian and cultural method
Technical field
The present invention relates to artificial breeding and the cultural technique of special aquatic products product, its method is from river waters, to catch wild Hunan catfish kind, according to the biological property of Hunan Nian, life habit and growth characteristic, the natural environment of manual simulation Hunan Nian breeding, growth, carries out artificial breeding and cultivation.
Background technology
The fisherman of Lake Dongting area and retailer think in Hunan, the southern catfish in money, river flowing from Guizhou Province through Hunan into Dongting Lake, Li tetra-water waters has two kinds always, and a kind of is common southern catfish, is commonly called as " depression ", and another kind is Hunan Nian, also claims " blue or green limit depression ".Two kinds of catfish have obvious difference in morphological feature and economic characters, should be two kinds or for subspecies, but are not admitted by aquatic products academia and biology expert so far.And in fact, not only there is notable difference in two kinds " depression " in form, and also completely different in selling price, Hunan Nian is Silurus Soldatovi Meridionalis 3-5 times.Aquatic products retailer and consumer trust Hunan Nian very much, and market conditions are always good, and for this reason, Dongting Lake southern catfish breeding breeding farm, Dongshan is since 2009, from the Changjiang river and Xiang River, Zi Shui, Wushui River collection Hunan Nian parent 180 tails, carry out the cultivation of special pond.Artificial propagation in 2011 success, hatching Hunan Nian 300,000 tails, cultivate Hunan Nian large size fingerling 180,000 tails, point give the ground raisers such as Hubei, Huarong, Yueyang, Yuanjiang and try to support, 120 mu of cultured areas, 180 mouthfuls, net cage, and carried out pond monoculture, raise together with and the test of net cage adult fish culture, also done two kinds of catfish cultivation comparative trials simultaneously, 300,000 jin of winter harvesting Hunan Nian in 2012, selling price is 30-60 yuan/kg, be 2.5-5 times of conventional catfish, liked by the masses.
Summary of the invention
1, biological property research and discovery.(1) resemblance.The Hunan relative Silurus Soldatovi Meridionalis of Nian build is longer, caudal peduncle account for body long 60%, long for height 5.8-6.8 times of body, long is long 6.2-6.6 times of body.Schistostoma is little compared with Silurus Soldatovi Meridionalis, ovalize, schistostoma after eye footpath, body colour, the seed stage is cinerous, without decorative pattern, adult fish stage major part is green-yellow, is still keeping the cinerous in seed stage on a small quantity, and being characterized as the most significantly anal fin edge is lividity, and properties and characteristics inheritance stability, therefore be referred to as " blue or green limit depression ".(2) life habit.Hunan Nian lives in Xiang River, Zi Jiang, Yuanjiang, the Lishui River and Upper Yangtze River, especially like perching at narrower, the long-term flowing water of the water surface, contain the section that oxygen is higher, benthon is abundant, Hunan Nian has a lively disposition, and happiness is swimming against the current, has significant difference with the habit of southern catfish docility.(3) growth characteristic.Hunan Nian in the fry stage taking zooplankton as main, the fingerling stage small fish and shrimp of ingesting, the artificial feeding fish gruel of ingesting.Hunan Nian does not have Silurus Soldatovi Meridionalis voracious like that, common degree of saturation is 50%-60%, and First Year growth rate is not as good as southern catfish, only 1kg of maximum individuality, and southern catfish can grow to 2.5-3kg the first year, Second Year growth rate is accelerated, and the Hunan catfish kind of general 250g can be grown to 3-3.5kg, and Hunan Nian ingests water temperature apparently higher than southern catfish, in water temperature below 20 DEG C, food ration reduces, and does not substantially ingest below for 15 DEG C, and Hunan Nian is applicable to high-density rearing.2, artificial breeding technology.(1) artificial propagation.By the end of April to mid-May, the male and female parent population of selectivity gland maturity, male and female are matched by a certain percentage, under the condition of 18 DEG C of water temperatures, the oxytocic drug such as manual injection LRH-A at twice, be 1/5 of accumulated dose for the first time, pour down for the second time surplus, the Hunan Nian parent population of having injected oxytocic drug is placed in to spawning pond, under the condition of 18-24 DEG C of water temperatures, the parent population that stimulated by oxytocic drug, after 6-10 hours, in succession oestrus and chase, now parent population is caught and carried out artificial insemination, with ethene net sheet make 60x100cm ovum plate, by fertilized egg uniform broadcasting on ovum plate, insert in hatchery and hatch.Under 20-24 DEG C of conditions of water temperature, within 48-56 hours, rear demoulding goes out fish fry.(2) fry rearing.Adopt the cement pit of 5 × 20 meters, clean up in advance with lime water or potassium permanganate thorough disinfection, after toxicity disappears, use bio-fertilizer, the water quality of fostering and apply fertilizer, transparency keeps 25-30 centimetres, after examination water, can grow dim, put Hunan catfish for every square metre and spend 500-1000 tails, every natural gift throw something and feed for 2-3 times water flea and red worm, owe depending on the rich of its bait, be aided with a certain amount of artificial granular bait for fish, cultivate after 10-15 days, fish fry grows to 3-4 centimetres, and a point pond proceeds to nurture of fish fingerlings.(3) nurture of fish fingerlings.With cement pit or Tu Chi, area 100-667 ㎡, put the front strict clear pond of seedling, sterilization, and cultivate water quality with bio-fertilizer or fertilizer, make Chi Shuizhong have more rich zooplankton, every square metre of water surface is put fry 15 tails of 3-4 centimetres of specifications in a suitable place to breed, bait throwing in 2-3 times every day, bait is mainly fish gruel and coordinates particle to raise, 10% left and right that day bait amount is body weight, make fingerling eat to 7-8 points full, notice that pond water quality changes, oxygenation 3-4 hours every day, make more than pond water oxygen content remains on 5 mg/litre, in the time that fingerling grows to 10-12 centimetres, divide once again pond depending on its density.3, adult fish culture technology.The fishpond of raising Hunan Nian is identical with foster southern catfish, general single pool area is 2-10 mu, 2-3 meters of the depth of waters, enter draining convenient, breeding water meets non-nuisance water supply standard, fishpond must be through cleaning up the pond, sterilization, especially send out over the years the fishpond of fish disease and must shine pond, thorough disinfection, after disappearing, toxicity throws in fingerling, put fingerling 500-1000 tails of 15-20 centimetres in a suitable place to breed for every mu, collocation 30-50 tail silver carps, bighead, main bait is wild fishes, chilled fish and manufactured feed, day bait amount is 6%-5%, every natural gift 9:30-10:00 in the morning, be that twice throwing of 17:00-18:30 raised afternoon, the new water of filling per week once, quantity of exchanged water is 1/5-1/6, by Changes in weather situation and fishpond water quality condition, increase aerator, the lime water of monthly splashing one time, each consumption is 15 kgs/acre, keep Chi Shui " fertilizer, live, tender, refreshing ", prevent that disease from occurring, promote that Hunan Nian grows up healthy and sound, under normal circumstances, every mu becomes fish crop can reach 1000-2500kg, feed coefficient is 4 left and right.
