Abstract

The invention discloses an intensive hatcher for American shads. According to the technical scheme, the intensive hatcher comprises a water storing pool, a hatching barrel and a net cage, tab water or disinfected and filtered river water or well water is poured into the water storing pool, aeration is fully performed, and the water temperature is controlled at 20 DEG C; the intensive hatcher is characterized in that a 75w water pump is placed in the water storing pool, and a water supply pipe of the water pump is connected with a water inlet pipe at the bottom of the hatching barrel; the hatching barrel is cylindrical; rows of holes are formed in the water inlet pipe in the hatching barrel, and water of the water pump flows into the hatching barrel through the rows of holes in the water inlet pipe of the hatching barrel; a sponge mat which is 2.5cm in thickness with a base area equal to that of the hatching barrel is placed above the water inlet pipe; 200 thousand fertilized eggs are placed in one hatching barrel; a flow adjusting valve is arranged on the water inlet pipe, and the fertilized eggs are kept turning over in a middle layer of the hatching barrel through flow adjustment; a water outlet of the hatching barrel is arranged at a position 5cm away from the top, and a water outlet pipe is 25mm in diameter; after the fertilized eggs are hatched, the water outlet pipe is placed in the net cage, and fries are hatched, and overflow from the water outlet pipe to enter the net cage.

Description

The intensive hatching apparatus of a kind of U.S. hilsa herring
Technical field
The present invention relates to a kind of hilsa herring incubating oosperm device.
Background technology
People always have a preference for famous and precious aquatic products, and still the Changjiang river hilsa herring of one of " the Changjiang river three delicacies " is due to overfishing, the deterioration of the ecological environment, and the Changjiang river hilsa herring disappeares substantially.U.S. hilsa herring is under the jurisdiction of Clupeiformes, clupeidae, hilsa herring subfamily, Alosa, belongs to a subfamily together with the Changjiang river hilsa herring of China, very approaching on taxonomy, taste and profile are also quite similar, because of but the fabulous substitute products of the Changjiang river hilsa herring.But at present, U.S.'s culturing reeves shads artificial propagation techniques is not mature enough, and hatching success is lower, has restricted the large-scale production of U.S. hilsa herring.
Summary of the invention
The object of the invention is to provide a kind of U.S.'s hilsa herring incubating oosperm device that improves incubation rate.
Technical scheme of the present invention adopts cistern, hatching pail and net cage, puts into running water or river or well water through sterilizing, filtering in cistern, and abundant aeration, and water temperature is controlled at 20 ℃; It is characterized in that putting in cistern the water pump of 1 75W, the feed pipe of this water pump connects the water inlet pipe of hatching pail bottom; Hatching pail is drum-shaped, bottom surface diameter 35cm, height 45cm; Hatching pail water inlet pipe diameter 20mm, this water inlet pipe has townhouse hole in hatching pail, and the townhouse hole of the current of water pump from the water inlet pipe of hatching pail enters hatching pail; It is that 2.5cm, the foam-rubber cushion identical with hatching pail base area disperse current that thickness is placed in water inlet pipe top, uses flow of inlet water to keep evenly in whole bottom surface; A hatching pail is put into 200,000 pieces, fertilized egg; On water inlet pipe, establish flow control valve, by adjustment flow, make fertilized egg remain on hatching pail middle level and stir; Hatching pail delivery port is located at apart from 5cm place, top, diameter of outflow tube 25mm; After incubating oosperm, outlet pipe is put into net cage, after prelarva membrane, from outlet pipe, overflow and enter net cage.
The present invention carries out high density hatching with flowing water, and controls the distribution situation of fertilized egg in hatching pail by current, avoids fertilized egg accumulation, thereby keeps sufficient dissolved oxygen and good water quality, and make the prelarva of membrane automatically separated, significantly improves hatching efficiency; Hatch completely, prelarva is all spilled over to collection net cage, more than total incubation rate reaches 85 ﹪, and hatching process without contaminate, change water, floor space, water consumption and manually all can reduce more than 50%, reduce seedling cost greatly.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of hatching apparatus of the present invention.
Embodiment
The present invention's (referring to accompanying drawing) adopts cistern 6, hatching pail 1 and net cage 5, puts into running water or river or well water through sterilizing, filtering in cistern, and abundant aeration, and water temperature is controlled at 20 ℃; In cistern, put into the water pump 2 of 1 75W, the feed pipe of this water pump connects the water inlet pipe of hatching pail bottom; Hatching pail is drum-shaped, bottom surface diameter 35cm, height 45cm; Hatching pail water inlet pipe diameter 20mm, this water inlet pipe has townhouse hole 7 in hatching pail, and the townhouse hole of the current of water pump from the water inlet pipe of hatching pail enters hatching pail; It is 2.5cm, the foam-rubber cushion 3 identical with hatching pail base area that thickness is placed in water inlet pipe top, through foam-rubber cushion, current is disperseed, and uses flow of inlet water to keep even in whole bottom surface; A hatching pail is put into 200,000 pieces, fertilized egg; On water inlet pipe, establish flow control valve 8, by adjustment flow, make fertilized egg remain on hatching pail middle level and stir, prevent from piling up, thus the dissolved oxygen of maintenance incubating oosperm abundance; Hatching pail effluent adopting overflow mode, delivery port is located at apart from 5cm place, top, outlet pipe 4 diameter 25mm; After incubating oosperm, outlet pipe is put into net cage, after prelarva membrane, from outlet pipe, overflow and enter net cage; Whole hatching process without contaminate, change water.
