The invention can wash the first breeding box clean after feeding baits each time, so as to keep good fattening environment and improve the quality of the portunid meat.
Description
Technical Field
The invention relates to the technical field of artificial breeding of portunids, in particular to a wild portunid fattening breeding box.
Background
The swimming crab has much meat, fat grease, delicious taste and rich nutrition. Each hundred grams of crab contains 14 grams of protein and 2.6 grams of fat. The fresh food is mainly steamed, and can be salted to process 'choking crab' and crab paste, and crab eggs are rinsed and dried in the sun to obtain 'crab seeds', which are superior products in sea products. However, as the crabs need to be shelled for a lifetime for more than twenty times, the shells of the crabs grow up once, the crabs are fatter before shelling, and the shells of the crabs are similar to a soft meat, at the moment, the crabs are called soft-shell crabs, and want to eat the soft-shell crabs regardless of the class or the heterogeneous, so that each shelling crab faces a ghost gate! This is also the reason why the survival rate of crabs is as low as less than 20% in nature. After several hours, the shell becomes hard, and the shell becomes thin and becomes empty crab. The crabs are continuously thinned by the fertilizer and then are thinned, and grow up in one day. According to practical observation, the shell of the crab needs about 3 to 20 days per shell, namely, the empty shell crab becomes fat crab for more than 20 days. Therefore, some wild swimming crabs caught are thin crabs and need to be put on the market after fattening, and the economic benefit is improved. Although some researches on fattening of swimming crabs exist at present, the swimming crabs are only fattened in the sea, are easily influenced by the natural environment and are inconvenient to manage. For indoor fattening, patent No. 201410150149.8 discloses an indoor circulating water three-dimensional ecological breeding device, although portunids defecate little and basically defecate once a day, beneficial bacteria are cultured in a breeding water body to decompose part of excrement and residual bait, in a breeding box with small space and small water flow, the residual excrement and bait are continuously increased and are not easy to diffuse, the water quality of portunids living is more and more turbid, the good living environment of the portunids is difficult to guarantee, the portunids are easy to get ill, the fattening growth of the portunids is not facilitated, and the quality is also influenced. And beneficial bacteria are cultured, so that the residual feces can be decomposed, but the beneficial bacteria consume oxygen in water, and the water quality of the crab life is further influenced.
