Fattening breeding box for easy feeding of swimming crabs

Abstract

The invention discloses a fattening breeding box for portunus crabs which is convenient for feeding. On the inner wall of the breeding box, the slide rail extends vertically from the bait feeding opening of the breeding box to the bottom of the breeding box; the sliding baffle for sealing the opening and closing of the feeding opening is arranged on the feeding opening; Entering and removing the bait tray at the bottom of the breeding box, which is composed of an inner bait tray movably set in the outer bait tray, the bottom of the inner bait tray and the outer bait tray are provided with a plurality of through holes, and the outer side wall of the outer bait tray A slide block corresponding to the slide rail on the inner wall of the breeding box is provided. Make the bait pan move up and down along the slide rail under the bait feeding port. The invention conveniently feeds the bait into the bottom of the breeding box to feed swimming crabs, and can conveniently remove the residual bait out of the breeding box by lifting the inner bait tray.

Description

technical field [0001] The invention relates to the technical field of portunus artificial breeding, and more specifically, the invention relates to a fattening and breeding box which is convenient for feeding portunus. 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, ...

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 a breeding box with small space and small water flow, it is very inconvenient to feed the feed, and it is even more troublesome to salvage the residual bait, which is not conducive to indoor fattening and breeding of Portunus
