Description
Technical field
The present invention relates to aquaculture, especially the breeding method of the yellow Fugu parent of chrysanthemum.
Background technology
The yellow Fugu of chrysanthemum (
takifuguflavidus) belong to Tetraodontiformes, Puffer suborder, Molidae, Fugu belongs to, and is mainly distributed in China's the East China Sea and the Yellow Sea and the Bohai Sea, belongs to coastal waters, temperate zone demersal fishes, the general migration not making long distance, mainly with the invertebrate such as shell-fish, shellfish and small fish for food, there is very high nutritive value and medical value, be described as first of " the Changjiang river three delicacies ".Its muscle is pure white as frost, and meat flavour fat is beautiful, fresh and tender good to eat, is rich in protein, nutritious, and its internal organs are containing the nerve element of severe toxicity, and be referred to as Tetrodotoxin (TTX), medically there is using value pole.In the river Puffer fingerling class cultivated at home, the chrysanthemum yellow Fugu market price is the highest, reach 150-200 unit/kilogram.
Along with Cultivar replacing and the structural adjustment of culture fishery, as the kind of special cultivation, the yellow Fugu cultivation of chrysanthemum is in view of its good economic worth, practical value and biological property have also been obtained very large development, cultured area constantly expands, but owing to being subject to the restriction of the factors such as geographical position weather, the yellow Fugu artificial propagation of chrysanthemum under the natural normal temperature condition in area, Jiangsu and Zhejiang Provinces could start in the first tenday period of a month in May, black prelarva seedling (total length 1cm) is cultivated at the beginning of 6 months, cultivate at the beginning of 7 months summer flower fingerling (total length 3-5cm) then fingerling generally can only grow to 50g/ tail, within 2nd year, also can only grow to about 200g/ tail, only have 20-30% to grow fish faster can go on the market, major part will to the 3rd year ability listing (300-350g/ tail), to survive the winter through 2 times like this, culture-cycle is longer, some problems below such existence: 1) overwintering period, particularly the yellow Fugu specification of the 2nd overwintering period chrysanthemum is relatively large, cultivation density is higher, and the survival rate that causes liable to illness is lower, 2) to cause raiser to drop into comparatively large the culture-cycle of 3 years, and the rate of capital turnover is lower, and take that the pond time is long, area is large.If impel chrysanthemum yellow Fugu parent sexual gland premature ripening by artificial regulatory, that just can do sth. in advance the artificial propagation of the yellow Fugu of chrysanthemum, for under in advance seed rearing and seed, race against time in the pool, the fingerling specification of such 1st year is larger, the ratio of listing in the 2nd year just increases, even can all go on the market, the rate of capital turnover, the pond utilization rate of raiser during also can improving whole cultivation.
Summary of the invention
The object of this invention is to provide a kind of method promoting chrysanthemum yellow Fugu parent sexual gland premature ripening.
The adult fish in selection of technical scheme color of the present invention pure, physically fit, atraumatic 3-4 age is as parent population, it is characterized in that the annual 6-10 month is by parent population pool cultivation outside, depth of water 1.5m, breeding density is 300-400 tail/mu, bait throwing in every day 2 times, daily ration of feeding is the 1-3% of parent population body weight, and bait is the eel feed containing crude protein 45%, throws something and feeds latter 2 hours at every turn, check food situation, pull residual raising in time out, adjust the daily ration, feeding quantity of next time simultaneously, monthly change water 1 time, to November, when outer pool water temperature drop is to 13 DEG C, parent population moves in simple and easy plastic tunnel pond and carries out overwintering culture, parent population is moved into before simple and easy plastic tunnel pond, pond must be repaired in desilting, then to clean up the pond sterilization by quicklime 150kg/ mu dry method, water filling just can put fish after 1 week, breeding density is 500-600 tail/mu, after parent population enters canopy, when water temperature is more than 13 DEG C, bait throwing in every day 2 times, during lower than 13 DEG C, bait throwing in every day 1 time, bait is the eel feed containing crude protein 45%, throw something and feed latter 2 hours at every turn, check food situation, pull residual raising in time out, adjust the daily ration, feeding quantity of next time simultaneously, when water temperature in booth does not change water lower than when 12 DEG C, when more than 12 DEG C, each quantity of exchanged water is no more than 30%, when more than 15 DEG C, each quantity of exchanged water can be increased to more than 50% depending on water quality condition, water temperature difference when changing water inside and outside canopy is less than 5 DEG C, at overwintering period, water temperature controls more than 10 DEG C, start parent population to January next year and move into indoor reinforced cultivating, water temperature is elevated to 17-19 DEG C gradually with the programming rate of 1 DEG C every day, and breeding density is 3-4 tail/m
2, continuous charge, gas exhausting stone density is 0.3-0.4/m
2, to shade film shading with bilayer, intensity of illumination controls at below 500lx, bait throwing in every day 2 times, bait is the eel feed containing crude protein 45%, supplement fresh razor clam, soil pick-up 1 time every other day, water is changed 1 time every 10 days, pond is turned over once every 30 days, reinforced cultivating 70-80 days at water temperature 17-19 DEG C, by the end of March at the beginning of-4 months, water temperature is raised to 21-22 DEG C, namely parent population raun individuality occurs that belly expands, sexual gland profile obviously and more soft, cloacal aperture slightly expands, gonapophysis is micro-red, the individual belly of parent population milter has sexual gland profile, slighter compress belly has milky seminal fluid to overflow, 80%-90% parent population gonad maturity.
The present invention is create a set ofly to comprise Juvenile stage relative to the outstanding feature of prior art, environment is equipped with, breeding density, bait is thrown in, the rational cultivate mode of time period interdisciplinary science of water temperature regulate and control and daily management regulation and control, the chrysanthemum yellow Fugu gonad maturity time is facilitated to do sth. in advance 1-1.5 month, guarantee the fingerling cultivating large gauge then, the ratio that Second Year can obtain listing specification (average 0.55-0.65 jin/tail) end of the year brings up to 60-80% from 20-30%, that is have 60-80% cultivation fish can reduce one to survive the winter the cycle, the average time of simultaneously forming marketable fish also shortened to 18-19 month from 26-28 month, add the turnover rate of the means of production, save production cost.The present invention is easy and simple to handle, is easy to be accepted and promote.
Embodiment
Production technology step comprises:
