Description
Technical field
The present invention relates to technical field of aquaculture, particularly relate to a kind of method of swimming crab nursery.
Background technology
Swimming crab, formal name used at school " decoy ", because carapace is shuttle shape, there are three projections in the central authorities of crust, so also known as Portunus trituberculatus Miers.Portunus trituberculatus Miers build is large, growth is fast, use value is high, delicious meat, nutritious, edible ratio are large, is not only of high nutritive value, but also has heat-clearing, the loose medical value such as blood and enriching yin.Mainly originate in the Huanghai Sea, the Bohai Sea and the East Sea.Due to the raising of people's living standard, marine products crab can not meet the growing demand of people, therefore starts artificial feeding.Portunus trituberculatus Miers tradition seedling raising process changes water in a large number, consumes mass energy, and increases production cost.Current natural waters is often polluted, seawater eutrophication, a large amount of bacterium, fungus breeding, brings very large impact to aquatic fry growing.Often change water in seedling raising process, the young, in order to shake down, needs energy i (in vivo) of beating, and reduces, which increase the cultivation time for the energy grown.The change of young living environment can make pathogenic microorganisms increase the threat of the young, just likely causes disease.In order to prevent and treat crab disease, many producers can use a large amount of agricultural chemicals, antibiotic and some high residue chemical synthetic drugs, what have is that pursuit growth rate and output even add chemical fertilizer and growth acceleration hormone in feed, thus crab Product quality and safety straight line is declined.
Chinese patent publication No. CN101755696A, date of publication on June 30th, 2010, name is called the method for Portunus trituberculatus Miers low latitudes season seeding and cultivation, this application case discloses a kind of method of Portunus trituberculatus Miers low latitudes season seeding and cultivation, in August to mid-October, from the natural marine site to the north of the Taiwan Straits or Portunus trituberculatus Miers culturing pool, obtain oogenesis Portunus trituberculatus Miers, ovigerous crab is transported to south (on the south the Taiwan Straits).With young crab as Portunus trituberculatus Miers seedling, carry out anti-season cultivation.The Portunus trituberculatus Miers of north cultivation can be cultivated in south.Its weak point is, changes water in a large number the immunity of swimming crab is reduced in seedling raising process, and cultivation survival rate reduces.
Summary of the invention
The object of the invention is to change water in a large number between conventional shuttle crab nursery stage to solve the immunity of swimming crab is reduced, the defect that cultivation survival rate reduces and a kind of method improving the swimming crab nursery of swimming crab juvenile crab immunity and survival rate is provided.
To achieve these goals, the present invention is by the following technical solutions:
A method for swimming crab nursery, said method comprising the steps of:
A) early-stage preparations: clear water soaked nursery pond after 1-2 days, with the bleaching powder of 50ppm-100ppm, nursery pond is carried out disinfection, rinse well with clear water again, after nursery pond dries, bottom nursery pond, laying depth is the ooze through sterilization of 4-8cm, then in nursery pond, introduce seawater, in nursery pond, add Bdellovibrio bacterium liquid and nitrifying bacteria liquid, make Bdellovibrio content in seawater reach 10
3-10
6the content of cfu/mL, nitrifying bacteria reaches 10
3-10
4cfu/mL, then shading leaves standstill 5-8 days;
B) lay eggs: in the nursery pond of step a), drop into the female crab be fertilized that ovum look transfers grey black to, idiosome heartbeat reaches 150-160 time/more than min, the cloth seedling density of nursery pond is 15-20 × 10
4individual/m
3;
C) post processing: after having laid eggs, pulls out female crab, and between nursery stage, bait of regularly throwing something and feeding, threw in a bacillus liquid every 5-7 days, in seawater, bacillus liquid concentration is 10
2-10
5cfu/mL.
In the technical program, in larval rearing water, nitrifying bacteria liquid is added in step a), nitrifying bacteria is the bacterium that mineralized nitrogen poisonous in water can be become nontoxic nitric acid state, and in the water of nursery pond, add nitrifying bacteria liquid, nitrifying bacteria can be made first to purify seawater, the poisonous mineralized nitrogen in seawater is become the materials such as nitric acid state;
Bdellovibrio is arc gram-Negative bacillus, and extensively distribution is with in waters soil and animal body, size 0.2-0.25 μm × 0.5-1.4 μm, extremely single flagellum, and motion is active.Bdellovibrio is a kind of bacterium parasitizing bacterium, can invest on the cell wall of host bacterium, and promptly pierce in host cell with the absorber of self, utilizes the nourishing and growing of host, breeds, finally cause the cracking of host bacterium.Bdellovibrio is selective to host, specially with Gram-negative bacterias such as vibrios, pseudomonad, Aeromonas, tardas for host, stronger to the cracking ability of pathogenic bacteria, add Bdellovibrio and can prevent growing the pathogenetic bacteria that crab is harmful to, effectively to avoid in swimming crab seedling raising process pathogenetic bacteria to the threat of the swimming crab young;
Step c) adds bacillus liquid in larval rearing water, bacillus can be bacillus licheniformis also can be bacillus subtilis, organic matter decomposition power is strong, can produce that abundant metabolism product, antibacterial, harmful power of going out are strong, the function of deodorizing, in seedling raising process, the ight soil that the young in each period produces can be decomposed by bacillus, avoids the pollution of water quality, the growth to crab young immune organ can be stimulated, strengthen immunity of organisms.
As preferably, the female crab before laying eggs is supported in wintering pond, and 1/2 of pond floor space lays the thick fine sand of 10-12cm, and depth of water controls at 0.6m-1m, salinity 25 ‰-30 ‰, female crab breeding density be 3-5 only/m
2, to throw something and feed shellfish meat or clam worm by the 5%-8% of body weight.
As preferably, when supporting female crab, under natural temperature, stablize 1-2 days, then start conditionting culture, promote production, wintering pond water temperature improves 0.5-0.8 DEG C every day, to 18-20 DEG C of constant temperature.
As preferably, before female crab input nursery pond is laid eggs, sterilize with 20mg/L-100mg/L formalin dipping bath 10-15min, clear water flushing.
As preferably, in step c), bacillus liquid adds in seawater by dry bacterium powder and brown sugar by weight the ratio of 1:2-4, and activation 6-8h, then filters, obtain bacillus liquid.
In the technical program, dry bacterium powder is added in seawater with brown sugar mixing tune, bacillus can be made to activate.
As preferably, the bacillus in bacillus liquid is bacillus subtilis or bacillus licheniformis.
As preferably, swimming crab Magna zoea larva Z
1phase throws something and feeds Micro Algae and wheel animalcule, and the daily ration, feeding quantity of Micro Algae is 50 × 10
