Abstract
The invention discloses an aquaculture method for improving Hanshou soft-shelled turtle egg laying amount and quality. The method includes the steps of carrying out daily management of an aquaculture pool, determining the proportion of female soft-shelled turtles and male soft-shelled turtles put into the aquaculture pool, preparing aquaculture feed and supplying the feed. The method has the advantages that operation is easy, raw materials are easy to get, production cost can be reduced, and the soft-shelled turtle egg laying amount and hatching survival rate can be improved; because incandescent lamps are additionally arranged in the aquaculture pool, more light can be scattered to the soft-shelled turtles, VD synthesis is promoted, lucipetal worms can be trapped, and more fresh protein bias can be provided for soft-shelled turtle aquaculture; because quick lime is applied, harmful organisms in water can be killed, the PH value of the water can be adjusted, and more calcareous substances can be supplied; the male soft-shelled turtle and female soft-shelled turtle aquaculture proportion is increased to (5-6):1, male soft-shelled turtles can be less injured, the soft-shelled turtle egg productivity is increased, and the egg laying amount is improved.
Description
Technical field
The present invention relates to technical field of aquaculture, be specifically related to a kind of cultural method that improves Hanshou soft-shelled turtle egg laying amount and the quality of laying eggs.
Background technology
The features such as " Hanshou soft-shelled turtle " belongs to authentic Shelled Turtle Trionyx Sinensis, for having the indigenous breed variety of distinct region feature, compares with other soft-shelled turtle kinds, becomes soft-shelled turtle to have body thin slice large, and shirt rim is generous, the white touched with red and solid colour of belly body colour; The meat of " Hanshou soft-shelled turtle " is pure, delicate, delicious, and its nutritive value and medical value are all better than other populations.The laying eggs of " Hanshou soft-shelled turtle " female soft-shelled turtle, incubation period cultivation are the important steps in whole feeding process, and at conventional temperature, the female soft-shelled turtle of the every 500g 20 pieces of left and right of laying eggs for a year, approximately hatch 15 young first; But in the May that starts to lay eggs every year, the many low temperature overcast and rainy days in Lake Dongting area, and soft-shelled turtle lacks in the later stage idiotrophic of surviving the winter, and egg laying amount and hatching success are now lower; And during late July to August, being subject to temperatures involved, the ovum that at this moment female soft-shelled turtle produces generally shows as depauperation, how incomplete embryonic development is or easily die from hatching process, normal emergence rate is low to moderate 45%, has seriously restricted the production of soft-shelled turtle seedling, greatly reduces raiser's income.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of cultural method that can improve Hanshou soft-shelled turtle egg laying amount and the quality of laying eggs is provided.
The cultural method of this raising Hanshou soft-shelled turtle egg laying amount and the quality of laying eggs, is characterized in that, cultural method is following steps:
One, the daily management of culturing pool
1. control the degree of depth of specific period culturing pool: the 4-5 month is reduced to 70-100cm by the water in culturing pool, more than the water in July culturing pool remains on 150cm;
2. control the fertility of culturing pool: the transparency of not timing ground claire water, when transparency is greater than 30cm, Chi Shui when so clear that you can see the bottom, to applying people's animal manure of becoming thoroughly decomposed in culturing pool in order to train water, every mu adds 150-300kg, makes Chi Shui keep light green or light brown; When transparency is less than 20cm, in culturing pool, inject clear water, each quantity of exchanged water is Chi Shui 1/10, makes Chi Shui keep light green or light brown;
3. within culturing pool 10-15 days, adopt the sterilization of quicklime slurry once, the consumption of quicklime is 50 grams, every cubic metre of water;
4. the incandescent lamp that each culturing pool is installed 2-3 100W is in order to increase the illumination at night;
5. spawning ground is located at the quiet place of culturing pool, and top, spawning ground is provided with sunshade, lays the moistening river sand that 20cm is thick below;
Two, in culturing pool, the male and female of soft-shelled turtle are thrown in ratio
The male and female input ratio of soft-shelled turtle is 5-6 ︰ 1, the male turtles that wherein the optional maturation of male soft-shelled turtle, body weight are 1000-1500g;
Three, prepare breeding feed
The raw material adopting is carrot 3-5 part, water spinach 3-5 part, unfertilized fresh tortoise egg 4-7 part being dropped, 51 parts of soft-shelled turtle parent trionyx sinensis feeds, 38 parts, water;
1. carrot clean after stripping and slicing to add poach ripe, the carrot normal temperature boiling was transferred to 20 minutes;
2. get and after cooling ripe carrot block mixes with water spinach, tortoise egg, put into beater and make slurry, in mixing slurry, add soft-shelled turtle parent's trionyx sinensis feed and water, standby after stirring;
Four, feed throws something and feeds
The nursing of soft-shelled turtle is meal every days two, throw something and feed the morning fresh bait spiral shell, freshwater mussel, small fish and shrimp, feeding volume be in pond soft-shelled turtle total amount 3%; Throw something and feed afternoon and be added with the breeding feed of carrot, water spinach and tortoise egg, feeding volume be in pond soft-shelled turtle total amount 1.5%.
Compared with prior art, the invention has the beneficial effects as follows: 1, method of operating is simple, easily learn well and understand, practical, and raw material are easy to get, and both can save production cost, and can improve significantly egg laying amount and the hatching survival rate of soft-shelled turtle.2, culturing pool is set up incandescent lamp, both can increase the illumination of soft-shelled turtle, promotes V
dsynthetic, can trap phototaxis insects again, increase the fresh and alive albumen bait of breeding soft-shell turtle.3, use quicklime and both can kill pest in water body, and regulated water PH value, eliminate the harmful microorganism of the soft-shelled turtle of causing harm, can increase calcareous supply again, supplement the needs of soft-shelled turtle to calcium.4, the cultivation ratio of male and female soft-shelled turtle is increased to 5-6 ︰ 1, can effectively reduces the damage of female soft-shelled turtle, increase the productivity of soft-shelled turtle ovum, improve egg laying amount.5, the water depth that regulates culturing pool by Various Seasonal, can promote growing of soft-shelled turtle, avoids because of low temperature or high temperature, it being grown and being impacted.6, regulate water body fertility, control water transparency, both can suppress harmful microorganism growth, promote beneficial microbe procreation, can effectively reduce the frequency accusing each other for soft-shelled turtle provides the hidden barrier of keeping away again, reduce soft-shelled turtle damage.7, in feed, add snakehead's egg, carrot and water spinach, after soft-shelled turtle food, have no side effect, can also strengthen the immunity of soft-shelled turtle, improved significantly the resistance of soft-shelled turtle and the quality of egg laying amount and ovum.
