Problems solved by technology

[0004] The present invention provides an integrated seedling pool and seedling transfer method for collecting and seedling larvae, so as to solve the problems in the prior art that there are many procedures for collecting and sending seedlings, and the mussels need to be treated multiple times in multiple processes. Transfer, transferring a large number of mussels in the farm for many times requires a lot of manpower, material resources and time, which seriously affects the technical problems of breeding efficiency

Embodiment 1

[0024] The present invention provides an integrated seedling pond for collecting and sending seedlings of sclerotia larvae, which can be used for collecting and sending seedlings of sclerotia larvae, such as figure 1 As shown, the seedling pond includes: parent-child clam basket 1 and fish pond 2, parent-child clam basket 1 and fish pond 2 are detachably connected; the middle part of parent-child clam basket 1 is a net rope surface 4, the middle and lower part is a 60-mesh sieve silk surface 3, and the top two The sides are respectively provided with ears 5 that can be hung on the fish pond. The bottom of the clam basket 1 is four slopes that gather toward the center. The center of the bottom of the clam basket 1 is provided with a timing valve 6. The fish pond 2 is a cuboid container. The bottom is provided with small-sized pulsator 7 and the water outlet 8 that can allow host fish to lead to juvenile clam cultivation pond.

[0025] Concretely, in this scheme, the clam-loving...

Embodiment 2

[0035] The invention provides a method for collecting and sending seedlings of sclerotia larvae, which is used for collecting and sending seedlings of sclerotia larvae. Put it in the parent clam basket 1, and dry it; when the timing valve at the bottom is closed, pour water from above to submerge the female mussel; The water injected into the fish pond 2 below carries out parasitism.

[0036] Specifically, in this scheme, the female clam with mature larvae is placed in the clam basket 1 to collect the larvae, and the host fish is placed in the fish pond 2 for breeding. Before parasitism, the clam basket 1 and the fish pond 2 can be placed separately It can also be placed together in combination. When placed separately, when the parasitic process is carried out, the clam basket 1 and the fish pond 2 must be combined and placed together.

[0037]It is necessary to collect the mature female mussels of the larvae first, wash them one by one, clean the dirt and moss on the surface...

Embodiment 3

[0042] The present invention also provides an optional embodiment: the butterfly clam is selected to collect the larvae, and the yellow catfish is used as the host fish to send seedlings. The ratio of the number of the butterfly clam to the yellow catfish is about 3:10.

[0043] In the practical application of the present invention, it is only necessary to fill the basket with water two hours after the mussels are screened and put into the basket, and then the process is automatically completed, and the transfer of the yellow catfish only needs to be carried out after the parasitism is over; and This transfer does not need to be salvaged, and only needs to turn on the switch leading to the juvenile clam culture tank, and push the fish that have not swum into it. In this way, the gap in the middle can be used to screen the next batch of mussels, improving the efficiency of time utilization. Each worker can control multiple pools in turn. The ratio of mussels to fish is about 3...

Abstract

The invention provides a glochidium collecting and sending integrated sending pond and a sending method. The sending method comprises the steps that female clams with mature glochidia are collected, moss and dirt on the surfaces of the female clams are washed away, and then the female clams are placed in a parent clam basket to be aired; when a timing valve at the bottom is in a closed state, a water pipe is used for injecting water from the upper part until the female clams are immersed; and after a preset time, the timing valve is automatically switched to be in an open state, and water containing the glochidia is injected into a parasitic pond below for parasitism. The technical problems that in the prior art, the number of collecting and seedling sending procedures is large, freshwater clams need to be transferred for multiple times in the multiple procedures, a large amount of manpower, material resources and time need to be consumed when a large amount of freshwater clams are transferred for multiple times in a farm, and the breeding efficiency is seriously affected are solved.

Description

technical field [0001] The invention relates to the technical field of collecting and sending seedlings of sclerotia larvae, in particular to an integrated seedling pool for collecting and sending scallops of sclerotia larvae and a method for sending seedlings. Background technique [0002] The larvae are the larvae of bivalve molluscs (such as mussels). In the mussel farms, collecting and cultivating the larvae is an important part of mussel culture. In the traditional collection and cultivation process of skeletal larvae, it is necessary to collect mature female mussels of stinger larvae, wash them one by one, clean the dirt and moss on the surface, and dry them in a cool place for 2-4 hours. Then put the female mussels stimulated by drying in the shade into the water again, and start to discharge the larvae that have gathered into flocs in about 10 minutes. When it is no longer discharged, use a sieve to filter out the mucus and dirt, and send the collected larvae to see...
