The invention discloses an observation box used for fry breeding in aquaculture. The observation box comprises a glass water tank made of transparent tempered glass, wherein the glass water tank has a cuboid-shaped structure; the upper end of the glass water tank is opened; an upper cover is buckled at the opened position of the upper end of the glass water tank; the upper cover is provided with an up-down through feeding inlet; and the end opening of the outer side of the feeding inlet is in abutting joint with a feed hopper. According to the invention, the mesh numbers of nylon nets of a first-grade test net, a second-grade test net and a third-grade test net are successively increased; through adjusting distances among the first-grade test net, the second-grade test net and the third-grade test net, the internal growing space of the glass water tank can be divided; fishes with different sizes penetrate through the nylon nets in a manner of penetrating holes; by matching with the mesh numbers of the nylon nets, the sizes and the growing conditions of fries can be efficiently learned; meanwhile, according to the concrete distribution information of the fries, the growing conditions of the fries can be rapidly learned.
Description
technical field [0001] The invention relates to the field of aquaculture, in particular to an observation box for seedling cultivation for aquaculture. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cage fish farming and f...
