Abstract
Disclosed is a method for promoting gonad early maturing of fugu flavidus parents. The method comprises selecting adult fish of 3 to 4 years old, which is pure in color, strong and trauma free, to serve as reserved parent fish. The method is characterized by culturing the parent fish in an outer pond from June to October every year; moving the parent fish into a pond simple plastic greenhouse in December for overwintering culturing; moving the parent fish indoors in January the next year, and strengthening culturing for 70 to 80 days at the water temperature ranging from 17 DEG C to 19 DEG C, and raising the water temperature to 21DEG C to 22 DEG C from the end of March to the beginning of April, wherein parent fish female individuals are distensible in abdomen, apparent and soft in gonad contour, slightly expanded in cloacal pore and slightly red in gonapophysis, and parent fish male individuals have gonad contours, milk white seminal fluids spills by lightly pressing hypogastria, and 80% to 90% of parent gonads are mature.
Description
Technical field
The present invention relates to aquaculture, especially the yellow Fugu parent's of chrysanthemum breeding method.
Background technology
The yellow Fugu of chrysanthemum (
takifugu flavidus) genus 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 of not making long distance, mainly, take the invertebrate such as shell-fish, shellfish and small fish as food, there is very high nutritive value and medical value, be described as first of " the Changjiang river three delicacies ".Pure white as the frost of its muscle, meat flavour fat is beautiful, fresh and tender good to eat, is rich in protein, nutritious, and its internal organs, containing hypertoxic nerve element, are referred to as Tetrodotoxin (TTX), have using value at the utmost point medically.In the river Puffer fingerling class of cultivation, the yellow Fugu market price of chrysanthemum is the highest at home, reach 150-200 unit/kilogram.
Along with the kind of culture fishery is upgraded and structural adjustment, as the kind of special cultivation, the yellow Fugu of chrysanthemum cultivates in view of its good economic worth, practical value and biological property have also 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, at the beginning of 6 months, cultivate black prelarva seedling (total length 1cm), at the beginning of 7 months, cultivate summer flower fingerling (total length 3-5cm) then fingerling generally can only grow to 50g/ tail, within the 2nd year, also can only grow to 200g/ tail left and right, only have the 20-30% fish faster that grows to go on the market, major part will arrive ability listing (300-350g/ tail) in the 3rd year, to survive the winter through 2 times like this, culture-cycle is longer, there are so following problems: 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 larger 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 can impel the yellow Fugu parent of chrysanthemum sexual gland premature ripening by artificial regulatory, that just can do sth. in advance the artificial propagation of the yellow Fugu of chrysanthemum, race against time for shifting to an earlier date the pool under seed rearing and seed, the fingerling specification of such the 1st year is larger, the ratio of listing in the 2nd year just increases, even can all go on the market, also can improve the rate of capital turnover, the pond utilization rate of raiser during whole cultivation.
Summary of the invention
The object of this invention is to provide a kind of method that promotes the yellow Fugu parent of chrysanthemum sexual gland premature ripening.
The adult fish in pure, physically fit, the atraumatic 3-4 of selection of technical scheme color of the present invention 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 in time residual raising out, adjust next daily ration, feeding quantity simultaneously, monthly change water 1 time, to November, when outer pool water temperature drops to 13 ℃, parent population moves in the simple and easy plastic tunnel in pond and carries out overwintering culture, parent population is moved into and survives the winter before canopy, pond must be repaired in desilting, then with the sterilization of cleaning up the pond of quicklime 150 kg/ mu dry method, water filling just can be put fish after 1 week, breeding density is 500-600 tail/mu, parent population enters after canopy, in the time that water temperature is more than 13 ℃, bait throwing in every day 2 times, during lower than 13 ℃, 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 in time residual raising out, adjust next daily ration, feeding quantity simultaneously, when water temperature in booth is not changed water during lower than 12 ℃, when more than 12 ℃, each quantity of exchanged water is no more than 30 %, when more than 15 ℃, more than each quantity of exchanged water can be increased to 50 % depending on water quality condition, while changing water, the inside and outside water temperature difference of canopy is less than 5 ℃, at overwintering period, water temperature is controlled at more than 10 ℃, start parent population to January next year and move into indoor reinforced cultivating, water temperature with every day the programming rate of 1 ℃ be elevated to gradually 17-19 ℃, breeding density is 3-4 tail/m
2, continuous charge, gas exhausting stone density is 0.3-0.4/m
2, with the bilayer film shading of sheltering from heat or light, intensity of illumination is controlled 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, changed water 1 time every 10 days, turned over pond once every 30 days, reinforced cultivating 70-80 days at water temperature 17-19 ℃, at the beginning of by the end of March-4 months, water temperature is raised to 21-22 ℃, 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, gently depressing belly has milky seminal fluid to overflow, 80%-90% parent population gonad maturity.
The present invention is to have created a set of parent of comprising to select with respect 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, facilitate the yellow Fugu gonad maturity time of chrysanthemum to do sth. in advance 1-1.5 month, guarantee can cultivate then the fingerling of large specification, Second Year can obtain the ratio of listing specification (average 0.55-0.65 jin/tail) end of the year and bring up to 60-80% from 20-30%, that is to say that 60-80% cultivation fish can reduce one and survive the winter the cycle, also shortened to 18-19 month from 26-28 month the average time of simultaneously forming marketable fish, increase 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.
