Wild swimming crab fattening breeding box

Abstract

The invention discloses a wild swimming crab fattening breeding tank comprising a gate capable of dividing the breeding tank into two parts and arranged in the middle of the breeding tank, wherein water communication of a first breeding tank and a second breeding tank separated by the gate is controlled by the gate; an actuator for driving the gate to be opened or closed; a first drain pipe for draining water in the first breeding tank when the gate is closed and a second drain pipe for draining water in the first breeding tank and the second breeding tank when the gate is opened. A first light source and a second light source are respectively disposed in the first breeding tank and the second breeding tank, and the second light source is disposed in a hiding chamber. A controller separately controls the actuator, the first drain pipe, the second drain pipe, a water pump, the first light source and the second light source. By means of the breeding box, the first breeding box can be flushed clean each time a feed is thrown to maintain a good fattening environment and improve the quality of swimming crab meat.

Description

technical field [0001] The invention relates to the technical field of portunus artificial culture, more specifically, the invention relates to a wild portunus fattening and breeding box. Background technique [0002] Swimming crabs have a lot of meat, plump fat, delicious taste and rich nutrition. Every 100 grams of crab contains 14 grams of protein and 2.6 grams of fat. Fresh food is mainly steamed food, and "choke crab" and crab sauce can also be salted and processed. Crab roe becomes "crab roe" after rinsing and drying, all of which are top grade seafood products. However, since a crab needs to molt nearly 20 times in its life, the crab will grow up once it molts its shell. The crab is the fattest before it molts, and it looks like a mass of soft meat just after it molts. At this time, the crab is called Soft-shell crabs, whether they are of the same kind or different kinds, want to eat them. It can be said that every time a crab molts, it faces a hell! This is also t...

However, since a crab needs to molt nearly 20 times in its life, the crab grows up once it molts its shell. The crab is the fattest before it molts, and it looks like a mass of soft meat just after it molts. At this time, the crab is called Soft-shell crabs, whether they are of the same kind or different kinds, want to eat them. It can be said that every time a crab molts, it faces a hell! This is also the reason why the survival rate of crabs in nature is as low as less than 20%.

Although there have been some researches on the fattening of Portunus, they are still limited to fattening in the ocean, which is easily affected by the natural environment and is not easy to manage.

For indoor fattening, the indoor circulating water three-dimensional ecological breeding device is mentioned in the patent No. 201410150149.8. Although the swimming crab does not defecate much, it basically defecates once a day. It also decomposes part of the fecal residual bait by cultivating beneficial bacteria in the cultured water body. However, in the breeding box with small space and small water flow, the residual feces and bait continue to increase, and it is not easy to spread. The water quality in which swimming crabs live will become more and more turbid, and it is difficult to ensure a good living environment for swimming crabs. The fattening growth of swimming crab also affects the quality

And although the cultivation of beneficial bacteria can decompose the residual bait of feces, the beneficial bacteria will consume oxygen in the water, which will further affect the water quality of crabs.
