Description

Lasa schizothorax biddy roe incubator

Technical Field

The utility model relates to an aquaculture field, especially a Lasa schizothorax fish roe incubator.

Background

The Lasa schizothorax prenanti fish is commonly called as the spiraea acuminata, is only distributed in the trunk, branch and auxiliary water bodies at the middle and upper reaches of the Yaluzan Bujiang in the Tibet region, has less resource amount, slow growth speed and late sexual maturity age, is a special species in China and is also one of the main economic fishes in the Tibet region. In recent years, the intensity of fishing has been increasing, exceeding the growth rate. In addition, many invasive fishes form natural populations in the water area of the Bruguiera communis, and have competitive relations with native fishes, so that the population quantity of the Schizothorax lanzakii is sharply reduced. Therefore, research and protection of the rassa belly fish resources are at hand. The proliferation and releasing of the Lassa Schizothorax is an effective channel for recovering resources.

The artificial incubation of fertilized eggs is a key technical link of artificial propagation. At present, the traditional fertilization and incubation of the Lasa schizothorax prenanti generally adopts an original incubation method of a cement pool and an incubation frame, the water mold is serious, a large amount of manpower is consumed for picking dead eggs, the fry production capacity is weak, and the large-scale production of the Lasa schizothorax prenanti is seriously hindered.

SUMMERY OF THE UTILITY MODEL

For solving the problem of artificial incubation of fertilized eggs of the lasa schizothorax fish, the utility model provides a fish egg incubator of the lasa schizothorax fish. The incubator occupies small area, effectively reduces the manpower input, and is suitable for the artificial propagation of large-scale Lassa Schizothorax.

The utility model adopts the technical proposal that:

the utility model provides a Lasa schizothorax fish roe incubator, includes hatching bucket and the inlet tube of setting in hatching bucket, the bottom of hatching bucket is the arcwall face, the bottom is provided with the water inlet, the equipartition has a plurality of apopores and one end to seal on the inlet tube, the open one end of inlet tube can be dismantled and connect the water inlet, the outside water inlet department of hatching bucket is provided with the connecting pipe, be provided with the valve on the connecting pipe, the gap has been seted up on the upper portion of hatching bucket, outside warning pipe is connected to the gap.

The detachable connection of the utility model is a threaded connection.

The aperture of the water outlet hole of the utility model is 2-3 mm.

Preferably, the height of the water outlet hole is not higher than that of the arc-shaped bottom surface.

The height of the gap from the bottom of the overflow gap is 55-65 cm.

The hatching barrel of the utility model is a transparent barrel.

The utility model has the advantages that:

1. a water inlet pipe with a water outlet hole is designed in the incubator, water columns sprayed out of the water outlet hole are jetted to the arc-shaped bottom of the incubator, the water columns are reflected back, fertilized eggs are enabled to keep uniform up-and-down rolling under the action of water flow, and meanwhile, no dead angle exists at the bottom of the arc-shaped surface, so that the roes cannot be accumulated at the bottom and die; after the fertilized eggs are hatched, light egg membranes and dead eggs float on the water surface and are discharged from an overflow port at the upper part under the action of continuous water flow. The incubator is suitable for incubating sinking spawns of Lasa schizothorax prenanti, dead spawns do not need to be removed, and a large amount of manpower and financial resources are saved.

2. The water inlet pipe of the incubator is designed to be detachable, after the fertilized eggs are incubated, the light egg membranes are discharged from the overflow port on the upper part, the fry are left in the incubator, the connecting pipe of the incubator is connected with the external fish pond, the water inlet pipe in the incubator is taken down, and the fry in the incubator are discharged from the water inlet to the fish pond below along with the water flow, so that the collection of the fry is completed.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Example 1

As shown in fig. 1, a hatching device for fish eggs of rassa schizothorax comprises a hatching barrel 1 and a water inlet pipe 2 arranged in the hatching barrel, wherein the bottom of the hatching barrel 1 is an arc-shaped surface, the bottom is provided with a water inlet 11, a plurality of water outlet holes 21 are uniformly distributed on the water inlet pipe 2, one end of the water inlet pipe is sealed, the opened end of the water inlet pipe 2 is detachably connected with the water inlet 11, a connecting pipe 3 is arranged at the position of the water inlet outside the hatching barrel 1, a valve 31 is arranged on the connecting pipe 3, a water overflow port 12 is arranged on the upper portion of the hatching barrel 1, and the water overflow port 12 is connected with an overflow pipe 4 outside.

Before the fish eggs are hatched, the connecting pipe 3 of the incubator is connected with an external water source, water flow continuously enters the water inlet pipe 2 from the water inlet 11 at the bottom of the incubator, and is sprayed into the incubator from the water outlet 21 of the water inlet pipe, and overflows from the overflow port 12 at the upper part of the incubator, so that the whole incubator is filled with water. Fertilized eggs are put in, the fertilized eggs of the Lassa schizothorax are sinking eggs which can sink downwards, water columns sprayed out of the water outlet holes 21 are beaten at the arc-shaped bottom of the incubator, the water columns are reflected back, the fertilized eggs are enabled to keep uniform up and down rolling under the action of water flow, and meanwhile, no dead angle exists at the bottom of the arc-shaped surface, so that the fish eggs cannot be accumulated at the bottom to cause dead eggs; after the fertilized eggs are hatched, the light egg membranes float on the water surface and overflow from the overflow port 12 at the upper part under the action of continuous water flow. After the fertilized eggs are completely incubated, the light egg membranes are discharged, the fries are left in the incubator, the connecting pipe 3 of the incubator is connected with an external fish pond, the water inlet pipe 2 in the incubator is taken down, the fries in the incubator are discharged to the fish pond below from the water inlet 11 along with water flow, and the collection of the fries is completed.

Example 2

The aperture of apopore is 2mm, does benefit to control water velocity of flow, can not damage the roe because of the water velocity is too high.

The height of apopore is not higher than the height of arc bottom surface, guarantees that apopore spun water can all beat the arc and reflect on the face.

Example 3

The aperture of the water outlet hole is 3 mm.

The detachable connection is a threaded connection.

The height of the overflow gap from the bottom is 55 cm. The fertilized eggs are not discharged from the overflow port because of the too low distance.

Example 4

The aperture of the water outlet hole is 2.5 mm.

The detachable connection is a threaded connection.

The height of the overflow gap from the bottom is 65 cm. The fertilized eggs are not discharged from the overflow port because of the too low distance.

Example 5

The aperture of the water outlet hole is 2.5 mm.

The detachable connection is a threaded connection.

The height of the overflow gap from the bottom is 60 cm.

The hatching barrel is a transparent barrel, so that the hatching condition of the fertilized eggs is conveniently observed.

The utility model discloses the connected mode that has not clarified is connected modes such as conventional welding, riveting, screw and bonding.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention.
