Background

With the continuous improvement of living standard of people, the demand of people for high-grade food such as marine products is more and more, and the marine products are in a short supply state at present and in a quite long time in future, so that the marine products have huge market space. At present, marine products are mainly obtained from two aspects, namely fishing from natural sea areas on one hand and artificial culture on the other hand. For over 10 years, due to the continuous progress of marine fishing technology and equipment in China, the rapid increase of the horsepower of a fishing boat and the rapid expansion of fishing teams and the inability to monitor fishing operation, the environment of an economic marine organism breeding habitat is seriously damaged, the amount of marine natural resources is sharply reduced, the resources which can be caught in a natural sea area are gradually reduced, and the number of marine products fished from the natural sea area is difficult to continuously increase, so that the increasing demand of people on marine products can be met only by artificial cultivation and resource recovery enhancement. China has a long coastline and a wide shallow beach, and is suitable for the culture of marine shellfish. At present, as the research and culture of biological baits are developed rapidly, various shellfish fry breeding technologies are broken through successively. Such as oysters, scallops, pearl shells, mussels and the like for hanging and breeding shellfish and clam, sinonovacula constricta and other varieties for shallow sea mudflat breeding form a great industry in certain coastal areas. The development of the industry is through breeding, fry breeding, intermediate fry breeding, cultivation, subsequent industry and the like. Although some varieties of the young shellfish successfully break through the fry breeding, a proper breeding facility and a breeding mode are not found in the intermediate breeding stage of the young shellfish, so that the supply of the young shellfish is in short supply, the breeding yield cannot be effectively improved, and the market price is high.

Detailed Description

The invention will be described in further detail with reference to the following drawings and specific embodiments:

example 1

As shown in fig. 1-2, the intermediate cultivating device for benthic shellfish offspring seeds provided in this embodiment includes a basket 1 and a detachable cover 2, wherein the basket 1 includes a side surface 11, a bottom surface 12 and an upper opening 13 enclosed by the side surface 11, a plurality of long through holes 14 are provided at an upper middle portion of the side surface 11, a first through hole 15 is provided on the upper opening 13, the cover 2 is in a grid shape, and a second through hole 16 is provided at an edge of the cover 2 corresponding to a position of the first through hole 15.

The elongated through holes 14 are uniformly arranged along the upper middle portion of the side surface 11.

The side surface 11 is tapered from the upper opening 13 toward the bottom surface 12.

The housing 1 may have a truncated pyramid shape in which the upper opening 13 is larger than the bottom surface 12.

In this embodiment, the housing 1 has a square-truncated-pyramid shape in which the upper opening 13 is larger than the bottom surface 12.

Specifically, in this embodiment, the side surface 11 is a trapezoid, and the upper opening 13 and the bottom surface 12 are squares.

Specifically, in this embodiment, two opposite long edges of the upper opening 13 are respectively and uniformly provided with 2 first through holes, and two opposite short edges of the upper opening 13 are respectively and uniformly provided with 1 first through hole 15.
