Problems solved by technology

[0003] The invention provides a method for using a facility for cultivating razor clam spat, which overcomes the high requirement on the water quality of the nursery pool in the existing cultivation stage of razor clam spat. Generally, the pool water needs to be replaced once every 1 to 2 days, and the water needs to be replaced when changing the water. Inverting the tank, these procedures are very easy to cause damage to juvenile shellfish, thereby reducing the survival rate, and it takes a lot of work to increase the cost, which restricts the healthy and sustainable development of the razor clam aquaculture industry to a large extent. Therefore, the present invention provides a method that can use The use method of the facility with low damage rate of razor clam seedlings, small damage, quick water change, simple cleaning, and favorable harvesting of juvenile shellfish

Embodiment 1

[0017] Embodiment 1: a kind of facility of cultivating razor clam spat, comprising nursery pool and nursery box,

[0018] The design of the nursery pool is as follows: the nursery pool adopts a cement pool, and a shelf for placing a nursery box is provided at a distance of 20 centimeters from the bottom of the pool. water cultivation pond;

[0019] The design of the seedling raising box is as follows: the specification of the seedling raising box is 100*60*40cm, 150 mesh nets are used as baffles around the seedling raising box, and the bottom is a net of 120 mesh apertures.

[0020] The use method of the above-mentioned facility for cultivating razor clam spat comprises the following steps:

[0021] (1) Laying gauze: first lay a layer of gauze at the bottom of the seedling box;

[0022] (2) Laying sea mud and fine sand: Lay a layer of 2cm sea mud after disinfection on the gauze, and lay a layer of fine sand after disinfection on the sea mud with a 120-mesh net sieve; The fi...

Embodiment 2

[0027] (7) Harvesting spat: After 13-17 days of cultivation, spat can be harvested when the shell length reaches more than 2mm. When harvesting, drain the pool water first, and pull up the gauze in the box to make the spat and sea mud together Fall off the bottom baffle, and then wash the sea mud in the box with a water gun, so that the sea mud will naturally leave the box, and then you can get spat that can be directly put into razor clam fields or ponds for cultivation. Embodiment 2: a kind of facility of cultivating razor clam spat, comprising nursery pond and nursery box,

[0028] The design of the nursery pool is as follows: the nursery pool adopts a cement pool, and a shelf for placing a nursery box is provided at a distance of 20 centimeters from the bottom of the pool. water cultivation pond;

[0029] The design of the seedling raising box is as follows: the specification of the seedling raising box is 100*60*40cm, the four sides of the seedling raising box adopt 200 ...

Embodiment 3

[0038] Embodiment 3: a kind of facility of cultivating razor clam spat, comprising nursery pool and nursery box,

[0039] The design of the nursery pool is as follows: the nursery pool adopts a cement pool, and a shelf for placing a nursery box is provided at a distance of 25 centimeters from the bottom of the pool. water cultivation pond;

[0040] The design of the seedling raising box is as follows: the specification of the seedling raising box is 100*60*40cm, 180 mesh nets are used as baffles around the seedling raising box, and the bottom is a net of 100 mesh apertures.

[0041] The use method of the above-mentioned facility for cultivating razor clam spat comprises the following steps:

[0042] (1) Laying gauze: first lay a layer of gauze at the bottom of the seedling box;

[0043] (2) Laying sea mud and fine sand: Lay a layer of 1.5cm sea mud after disinfection on the gauze, and lay a layer of fine sand sieved with a 120-mesh net on the sea mud after disinfection; The...

Abstract

The invention discloses a device for culturing juvenile Sinonovacula constricta and a usage method of the device. The device comprises a nursery pond and nursery boxes, wherein the nursery pond is a cement pond, a shelf for accommodating the nursery boxes is arranged in a position 20-30 cm away from the pond bottom, and an alga-laden water culture pond with a water outlet higher than the surface of the nursery pond is arranged on one side surface of the nursery pond; each nursery box has the specification of 100*60*40 cm, a net of 150-200 meshes is arranged on the periphery of the nursery box to be used as a baffle, and a net with the hole diameter of 80-120 meshes is arranged at the bottom. The usage method comprises seven steps including gauze laying, sea mud and silver sand laying, sterilization of the nursery pond and accommodation of the nursery boxes, seedling launching, water feeding, water changing during culture of the juvenile Sinonovacula constricta and harvesting of the juvenile Sinonovacula constricta. The device has the characteristics of low damage rate, small injury, high water changing speed, simplicity in washing and the like, the culture survival rate is substantially increased, the cost is reduced, and sustainable development of the Sinonovacula constricta culture industry is promoted.

Description

technical field [0001] The invention relates to the field of artificial breeding of aquaculture seedlings, in particular to a method for using a facility for cultivating spat of razor clams. Background technique [0002] Constricted razor clams are molluscs, bivalve clam shellfish, living in the tidal flats of sea areas, and are common seafood ingredients. The shell is brittle and thin, oblong and square. From the top of the shell to the edge of the abdomen, there is an oblique groove, so it is called razor clam. The meat of razor clams is sweet and salty, cold in nature, and enters the heart, liver, and kidney meridian. , Drunkenness, etc. also have a certain therapeutic effect. Razor razor clam culture is one of the four traditional cultured shellfish in China, and occupies an important position in my country's mariculture industry. However, due to a large number of reclamation and industrial pollution along the coast, the natural seed resources of razor clams have been...
