Problems solved by technology

Water quality is seriously affected by bait, scallop excrement, temperature, etc., and due to the need to heat up, the whole process requires a lot of manpower, material resources and energy; and the premise of natural seedling collection is that there are a large number of seed shells in the breeding sea area and are affected by ocean currents. And every year, it is necessary to test and track the flow of Ezo scallop larvae with the ocean current. According to incomplete statistics, the amount of natural seedlings collected in my country is very small. From an economic point of view, the natural seedlings collected are not proportional to the material resources consumed. Therefore, it is urgent to hope for a new breeding method of Ezo scallop seedlings to change the status quo

Embodiment 1

[0042] Put the scallop seedlings in the D-shaped larval stage selected and bred in the indoor nursery room into the scallop seedling breeding device at a concentration of 1 / mL, and the growth of the scallop seedlings needs to be monitored and measured throughout the process , when the average size of shellfish larvae is greater than 250 μm, and the proportion of eye-spot larvae is 5-10%, put in the attachment bag. Larval shell length data such as Figure 4 shown.

[0043] From the time when the shellfish larvae were put in, the test monitoring data before putting in the attachment bag are shown in Table 1:

[0044] Table 1 Density and distribution of shellfish larvae in cages before putting in attached bags

[0045]

[0046] Depend on Figure 4 It can be seen from Table 1 that the seedlings are growing all the time, and the seedlings are mainly concentrated in the upper layer, and as time goes by, some larvae have died, and all the larvae that survive are strong scallop ...

Abstract

The invention relates to a patinopecten yessoensis spat breeding device and method, and belongs to the technical field of patinopecten yessoensis spat breeding. The patinopecten yessoensis spat breeding device comprises a net cage, and the net cage comprises a frame (1), a bolting silk net (2), buoys (3) and a sunshade net (4), wherein the bolting silk net (2) is arranged around the frame and on the bottom of the frame; the buoys (3) are arranged around the top of the net cage, and the sunshade net (4) is arranged on the top of the net cage. The device further comprises an attachment bag (5) which is separated from the net cage, and the attachment bag can be hung in the net cage. By means of the breeding device, breeding and attached growth of patinopecten yessoensis can be achieved in offshore open sea without manually adding baits, the quality and the quantity of the survival patinopecten yessoensis spat can be ensured, and the high-quality spat is provided for bottom sowing.

Description

technical field [0001] The invention relates to the technical field of scallop breeding, in particular to a seedling breeding device and method of Ezo scallop. Background technique [0002] At present, the breeding methods of Ezo scallop seed are mainly divided into two types, that is, indoor temperature-raising seedling cultivation and natural seedling harvesting. Among them, indoor seedling cultivation needs to accelerate the ripening and spawning of the seed shells under the premise of strictly controlling the physical, chemical and biological indicators of the water quality. Water quality is seriously affected by bait, scallop excrement, temperature, etc., and due to the need to heat up, the whole process requires a lot of manpower, material resources and energy; and the premise of natural seedling collection is that there are a large number of seed shells in the breeding sea area and are affected by ocean currents. And every year, it is necessary to test and track the f...
