Description

A kind of prawn family culture device and using method thereof

technical field

The invention relates to the field of aquaculture equipment, in particular to a prawn family culture device and a method for using the same.

Background technique

In the seed conservation breeding stage of shrimp breeding, after selecting groups with different growth characteristics (such as fast growth, strong disease resistance, and large adult size) in a family, separate seedlings or cultures are carried out. And in the early stage of nursery or breeding process, the larvae of prawns have high requirements on the quality of the water body. If the water body is polluted or the cleanliness of the water body is not high, it will cause large-scale illness of larvae or large-scale death of larvae. In the early stage of the breeding process, the water body needs to be replaced. Since the individual of the seedlings is small, it is necessary to prevent the seedlings from flowing out with the water body during the process of changing the water body. In the later stage, due to the larger individual size of prawns and enhanced resistance, but because the water contains metabolites of prawns, in order to ensure the cleanliness of the water body, the water body can be replaced by a long-flow and fixed water level drainage method, so that Ensure the cleanliness of the water body.

Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The present invention is described with reference to Fig. 1-3 as follows:

A prawn family breeding device and its use method, comprising a breeding tank 1, a replaceable sewage pipe, a number of water inlet pipes 4, an aerator, an air stone 5, and a trachea 6, and a number of water inlet pipes 4 are located on the top of the breeding tank 1 , several water inlets are concentrated seawater pipelines, natural seawater pipelines, and freshwater pipelines. The bottom of the breeding tank 1 is gradually deepened from the edge to the middle so that the sewage is completely discharged. The sewage pipe is threadedly connected to the middle part of the bottom of the breeding tank 1. 6 is communicated, and trachea 6 is fixed on the blowdown pipe, and the bottom of culture bucket 1 is provided with drainpipe 7, and drainpipe 7 is communicated with blowdown pipe, and some water inlet pipes 4 and drainpipe 7 are all provided with switch 8, and the bottom of culture bucket 1 The bottom is also provided with a support seat 9, and the support seat 9 is provided with a groove 10, and the drain pipe 7 is located in the groove 10.

The sewage pipe includes a first sewage pipe 2 and a second sewage pipe 3, the first sewage pipe 2 is provided with first sewage holes 201 uniformly arranged along its length direction and its circumferential direction, and the first sewage pipe 2 is provided with The filter screen is sleeved on the first sewage pipe 2. The second sewage discharge pipe 3 is provided with a second sewage discharge hole 301 , the diameter of the first sewage discharge hole is smaller than the diameter of the second sewage discharge hole 301 , and the second sewage discharge hole 301 is located at the upper end of the second sewage discharge pipe 3 .

A kind of prawn family culture device and using method thereof, its operation method is as follows:

In the early stage of breeding: place the larvae with a specification between P10 and P15 in the culture tank, and connect the first sewage pipe 2 with the filter screen to the middle part of the bottom of the culture tank 1. At this time, the larvae in the larvae stage The size of the prawn larvae is small, and the filter screen is used to prevent the prawn larvae from being discharged with the replacement of the water body. Increase the water level in the breeding tank by 5-10cm every day. When the water level reaches the highest level, turn on the switch on the sewage pipe, discharge more than 50% of the water in the breeding tank, feed the feed regularly, and replace the filter screen according to the size of the prawn larvae. In the initial stage of the early breeding period, the size of the larvae of the larvae between P10 and P15 is small, and the mesh of the filter screen is 60 mesh. , Replace the filter with a 20-mesh filter.

Middle stage of cultivation: At this time, along with the growth of prawns, their individual size increases, when the individual size of prawn larvae increases to be greater than the diameter of the first sewage outlet 201, the filter screen is removed, and the switch 9 on the drain pipe 8 is opened regularly The water body in the culture tank 1 is replaced, and at the same time feed is fed and the aerator is turned on to increase the oxygen in the water body in the culture tank 1 .

Late breeding period: At this time, the size of the prawn larvae continues to increase, and the resistance of the prawn larvae increases, so there is no need to replace the water body as a whole. Replace the first sewage pipe 2 with the second sewage pipe 3, turn on the aerator to increase the oxygen in the water body in the culture tank 1 and feed the feed regularly, open the natural seawater pipe in the water inlet pipe 4 and the switch on the drain pipe 8 9. Since the second sewage outlet 301 is located at the upper end of the second sewage pipe 3, when the water level in the culture tank 1 rises to the position of the second sewage outlet 301, the water will flow out from the second sewage outlet 301, making the culture tank 1 The internal water body is in a state of constant water level.

In the early stage of breeding, if the salinity of the water body where the prawn larvae hatch is higher than the salinity of the natural seawater, open the concentrated seawater pipeline in the water inlet pipe 4, if the salinity of the water body where the prawn larvae hatch is the same as the salinity of the natural seawater , Open the concentrated natural seawater pipeline in the water inlet pipe 4.

In the middle stage of cultivation, in order to make the larvae of prawns adapt to the salinity of the water body of the natural environment to be grown in the future, the water body in the culture tank 1 is adjusted for salinity, and now the switch 9 on the fresh water pipeline in the water inlet pipe 4 is opened, The salinity of the water body in the culture tank 1 is adjusted. In the later stage of cultivation, in order to prevent the prawns from jumping out of the cultivation bucket 1, the cultivation bucket 1 is socketed with a block.

Adopting the above-mentioned technical scheme, the beneficial effects of the present invention are as follows: the middle part of the prawn family culture device and the culture barrel provided by the present invention is provided with a replaceable first sewage pipe and a second sewage pipe. There is a filter screen. When changing the water body, the filter screen prevents the larvae of the prawn family from flowing out with the water body. The first sewage pipe and the second sewage pipe can be replaced according to the larvae of the prawn family and different growth stages, and different replacement methods are adopted for the water body. , so as to ensure the cleanliness of the water body, and the replacement process of the first sewage pipe and the second sewage pipe is simple and quick, convenient to operate, saving time and effort.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection.
