Abstract
The invention relates to an incubation and seedling-culturing method of Tilapia and a production device. The incubation and seedling-culturing method of the Tilapia is formed by the connection of a water pump, a main water inlet pipe, an incubatory barrel, a seedling collecting tank, a header tank, a return conduit, a reservoir and the like. The factory incubation method of the Tilapia comprises the following steps of: (1) mating of parent fishes: the mating of parent fishes is implemented in a net cage, the parent fishes are put into the net cage and the mating and the ore laying can be performed when the temperature of water reaches over 20 DEG C. (2) artificial fetching of ores: the ores are fetched out of the oral cavity of the female fish and conveyed to an incubation workshop after being cleaned. (3) incubation on the production line; a main water inlet valve of the production line is opened and the water pump is started up. The fish ores are conveyed into the incubatory barrel, a water inlet valve of the incubatory barrel is dimensionally adjusted so that water stream causes the eggs to turn over at the middle and lower parts of the barrel, the fish seedlings flow into the seedling collecting tank subsequent to the incubation and are then collected for seedling culture. The invention can carry out the mass production of the Tilapia in multiple seasons and 24 hours per day, which meets the demands of the seedling culture in distinct seasons and sufficiently gives play to the effect of technical devices and fishery technologies in the production of seedlings culturing.
Description
Technical field
The invention belongs to the propagation technique of aquatic products and hatching, seedling-cultivating method and the production equipment of equipment, especially Tilapia mossambica.
Background technology
Tilapia mossambica is the improved seeds that FAO (Food and Agriculture Organization of the United Nation) is recommended, its output height, and premunition is strong, and feeding habits are wide, are easy to culture.Formed industrialization and foreign exchange earning in China, especially cultured very extensive in south China.The offspring breeding method of Tilapia mossambica mainly is by the natural propagation in the pond of female, male parent population at present, manually fishes in the pond with diddle-net after fry hatches again.Operation has blindness like this, and artificial very difficult fry in the pond is copied caught totally; Parent population eats ovum in addition, eats fry in the pond habit; Do not copy can eat fry after clean fry grows up yet early stage, and strive bait with fry and adult fish, strive water, strive fertilizer, has a strong impact on the efficient and the quality of producing seedling.On the other hand, the fish breeding phase can only be confined to the short period in summer.It is big that such fish breeding breeding mode takies the pond area, produces the weak point in season, is subjected to weather effect bigger, and production efficiency is low, and the seed size is uneven, can not satisfy the demand in enormous quantities to Various Seasonal, different size nurture of fish fingerlings.
Summary of the invention
For solve only rely in the present Tilapia mossambica fry production process natural self-produced, production efficiency is low, the production present situation that season is short, scientific and technological content is few, the invention provides a kind of Tilapia mossambica hatching m and apparatus for production line, can carry out the batch production production of many seasons, round-the-clock, in enormous quantities, automatic control hatching.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of industrial Tilapia hatching production line is characterized in that:
By water pump, main water inlet tube, hatching pail, collection seedling case, water leg, return duct, devices such as cistern connect to form.
Water pump is arranged in the cistern, connects main water inlet tube.
Cistern is collected recirculation water, periodical feeding.
Inlet valve is installed on the main water inlet tube and is connected, the valve that can regulate the current size is installed on hatching pail water inlet pipe top with the hatching pail water inlet pipe;
The hatching pail bottom is for taper shape or hemispherical and be fixed on liftoff about 1 meter height, is convenient to operation.The beam formula is adopted in the water inlet of hatching pail, and promptly water inlet pipe enters hatching pail from top, the mouth of pipe and its distance from bottom 2-5 millimeter.Outlet pipe is opened at 35 millimeter places, distance bucket upper end, is tilted to down.
Collection seedling case places the water leg top, and the side has apopore and with close gauze involution, prevents the outflow of ovum and fry.
Water leg is collected the water that flows out from collection seedling case, and by return line flow to cistern.
Single hatching pail, collection seedling case are formed the hatching unit of a hatching telotism; Several hatching units are connected in parallel and form the wall scroll production line; Several wall scroll production lines are connected in parallel and form the hatching workshop of corresponding scale.
A kind of factory incubation method of Tilapia, its feature may further comprise the steps:
(1), parent population mating: the parent population mating is carried out in net cage, and every square metre of net cage is put 3-4 kilogram parent population, but reaches 20 degree mate and oviposit just when above when water temperature.
(2) manually get ovum: from the raun oral cavity, get ovum, after cleaning, change the hatching workshop over to.
(3), production line hatching: open the inlet valve on the main water inlet tube on the production line, open water pump.Fish-egg is put into hatching pail, regulates hatching pail water inlet pipe valve size, and current make ovum seethe in the bucket middle and lower part, after fry hatches, flows into collection seedling case, collects fry and carries out seed rearing.
Beneficial effect of the present invention: can carry out in enormous quantities, many seasons of Tilapia mossambica seedling, round-the-clock production, satisfy the needs of the seed rearing of Various Seasonal, give full play to technical equipment and fishery science and technology in the effect of growing seedlings in producing, significant to the development that promotes the Tilapia mossambica industry.

Embodiment
Mating in the parent population net cage: the parent population mating is carried out in net cage, the net cage rectangle, and length-width-ratio is 3: 1,18 square metres of areas, dark 1 meter, 1 millimeter of mesh size.Net cage is arranged in the pond, 5 mu of pond areas.Net cage exceeds 0.3 meter of the water surface, and distance is 1.2 meters between net cage and the net cage.Female, male parent population carried out proportioning by 2: 1, and every square metre of net cage is put 3.5 kilograms of parent populations, when water temperature reaches 20 degree mate and oviposit when above, adopted ovum after 3 days.
The collection of fertilized egg: during centralized procurement, get out the raun gill cover with hand, water is gone out the ovum grain in the oral cavity.The ovum grain is through cleaning, remove impurity after, change the hatching workshop over to.
Production line hatching (consulting accompanying drawing): gathered 16 net cages, about 520,000 ovum have opened two production lines.Open the inlet valve on the main water inlet tube 32 on the production line, open water pump 1, the water of cistern 11 collects seedling device 8 and enters water leg 9 after return duct 10 backflow cisterns 11 through net grid apopore 12 through water inlet pipe 3, hatching pail water inlet pipe 5, hatching pail 6, hatching pail outlet pipe 7, inflow.Each hatching pail is put into the fish-egg about 20,000, regulates hatching pail water inlet pipe valve 4 sizes, and current make ovum seethe in the bucket middle and lower part.Open temperature controller, make the hatching water temperature at 28 degree, fry hatches the back and flows into collection seedling case, gathers up fry, changes the pond over to and carries out seed rearing.
