The invention also provides a method for carrying out propagation and culture by using the attached shellfish sea area proliferation device. The invention solves the technical difficulty of bottom sowing of the attached shellfish, can realize fixed-point and accurate putting, prevents the offspring seeds from being washed away by ocean currents, has easily obtained used materials and is simple and convenient to operate.
Description
Technical Field
The invention belongs to the technical field of aquaculture, and particularly relates to an attached shellfish sea area proliferation device and a proliferation method.
Background
China is a big aquaculture country, and shellfish is an important support for aquaculture yield. At present, in shallow sea of China, shellfish mainly adopts two modes of raft culture and bottom sowing culture, wherein most bottom sowing culture varieties are buried shellfish such as clams and philippines, and attached shellfish such as mussels and chlamys farreri mainly adopts raft culture mode. The attached shellfish is difficult to be cultured by bottom sowing mainly because the culture area suitable for bottom sowing is limited, the difficulty of bottom sowing is high, the harvesting is difficult and the like. However, for some special areas and attached shellfish, the bottom sowing culture method is more practical, but a better bottom sowing method is lacked.
Disclosure of Invention
The invention aims to provide an attaching type shellfish sea area proliferation device and a proliferation method, which provide technical support for attaching type shellfish sea area proliferation.
The invention is realized by the following technical scheme:
an adhering type shellfish sea area proliferation device comprises a multilayer stepped cone component, the height of the component does not exceed the length of the bottom edge, and a fixed ring extends out of the top of the cone.
The invention also provides a method for carrying out propagation and culture by using the attached shellfish sea area proliferation device, which comprises the following steps:
1) location of proliferation sea area
Selecting a naturally distributed rock reef area or an artificial fish reef area for putting; or trial release and development are carried out in a region without natural distribution;
2) shellfish pre-attachment
And (3) soaking the attached shellfish sea area proliferation equipment in a running water culture pond for more than 24 hours, uniformly sowing the prepared large-size shellfish seeds on the steps of the proliferation equipment, or wrapping the shellfish seeds on the vertical surface of the stepped vertebral member by using a mesh sheet with mesh buttons smaller than the shellfish seeds, stabilizing the shellfish seeds in water for more than 2 days, and tearing off the mesh sheet. Collecting scattered spat, replacing a batch of proliferation equipment, and repeating the operation;
3) delivery method
Before putting in, the attached shellfish sea area proliferation equipment pre-attached with shellfish in the step 2) is moved to a putting ship, the exposure time of the shellfish seedlings is not more than half an hour, and if the exposure time is too long, the shellfish seedlings must be splashed once by using natural seawater every half an hour;
when the shellfish breeding device is thrown, a spherical weight of 3-5kg is added to the bottom of a bearing hook, the bearing hook is used for hooking a fixed ring at the top of the attached shellfish breeding device in the sea area, the attached shellfish breeding device in the sea area and the attached shellfish are thrown to the seabed of a target area, the bearing hook automatically unhooks under the action of the additional spherical weight, and the operation is repeated.
Compared with the prior art, the invention has the beneficial effects that:
1. the invention solves the technical difficulty of bottom sowing of the attached shellfish and provides an attached shellfish sea area proliferation device.
2. The invention can realize fixed-point and accurate putting, and the seedlings can not be washed away by ocean currents.
3. The invention has the advantages of easily obtained materials and simple and convenient operation.
Detailed Description
To further explain the technical process of the present invention, the attached Mytilus coruscus is taken as an example for explanation.
An adhesion type shellfish sea area proliferation device is shown in figure 1, and comprises a multi-layer stepped cone member with a height not exceeding the length of the bottom side, and a fixed ring extending from the top of the cone. The proliferation apparatus is a multilayer stepped rectangular pyramid component, the bottom side length is 50cm, the step width and the step height are equal and are 3cm, the component is 9 layers in total, and a fixed ring extends out of the top of the uppermost vertebral body. The weight of the vertebral body is above 25 kg.
The method for breeding the mytilus coruscus by using the attached type shellfish sea area breeding device comprises the following steps:
1. location of proliferation sea area
The mytilus coruscus is distributed in the coastal areas of south and north China, and a rock reef area or an artificial fish reef area with natural distribution in the sea area of the large swertia davidi island is selected for putting.
2. Shellfish pre-attachment
Placing the attached type shellfish sea area proliferation equipment 2 in a running water culture pond, soaking for more than 24 hours, uniformly sowing the large-size mytilus coruscus fries which are prepared in advance and have an average shell height of 1cm on the steps of the proliferation equipment, and wrapping the mytilus coruscus on the vertical surface of the step type vertebral body component by using a part of meshes with meshes smaller than the mytilus coruscus. Stabilizing in water for more than 2 days, and tearing off the mesh. Collecting scattered spat, replacing a batch of proliferation equipment, and repeating the operation.
3. Delivery method
Selecting weather with small stormy waves, transferring attached shellfish sea area proliferation equipment of the attached mytilus coruscus fries to a throwing ship, and splashing the fries with natural seawater every half hour.
When the shellfish breeding equipment is thrown, a spherical weight of 3-5kg is added to the bottom of a bearing hook, the bearing hook hooks the top fixing ring of the attached shellfish breeding equipment in the sea area, the attached shellfish breeding equipment and the attached shellfish are thrown to the seabed of a target area by manpower or a cable car, the bearing hook automatically unhooks under the action of the additional weight, and the operation is repeated.
