Description

Equipment is supported temporarily to gulfweed based on circulating water

Technical Field

The invention belongs to the technical field of fishing devices, and particularly relates to a temporary rearing device for opsariichthys bidens based on circulating water.

Background

Common and famous maigre (Opsarichthys bidens) furcate fish, mahogany, elopichia bambusa, creeping in a pit, widening in a mouth, digging in a large mouth, tearing in a female mouth and making a male red car. It is produced in the water areas of Nanchejiang river, Yuanjiang river, cang river, etc. Is a kind of omnivorous freshwater fish with meat preference.

Long and flat side, round abdomen. The kiss is long and the mouth is large; the cleft mouth inclines upwards, the back end of the lower jaw extends to the front edge of the eye, the front end of the cleft mouth is convex, two sides of the cleft mouth are respectively provided with a recess, and the cleft mouth is just embedded with the front end of the upper jaw and the concave-convex parts at the two sides. The middle-large of the eye. The lateral line is complete, the front section bends to the side abdomen of the body, and the rear section extends upwards to the center of the caudal peduncle. The back of the body is gray black, the abdomen is silvery white, the body side is provided with light blue vertical stripes, and the pectoral fin, the ventral fin and the gluteal fin are orange yellow. The male fish appears 'wedding dress' in the reproductive period, head, osculum and buttockfin have obvious pearl star, and buttockfin 1~ 4 branch fin lines prolong very much, and the whole body has bright-coloured marriage colour.

At present, when people catch the opsariichthys bidens in the Taihu lake, the opsariichthys bidens is generally caught by using tools such as a traditional hanging net, a lifting net, a rotating net and the like, and because the opsariichthys bidens like to live in water terrain with more weeds, more reeds, more wooden piles, more riprap and the like, a great number of opsariichthys bidens are difficult to catch by using the traditional net tool, and the traditional net tool is a fixed net tool, so that the opsariichthys bidens is large in size, inconvenient to carry, small in catching amount and poor in catching effect.

Disclosure of Invention

The invention aims to provide temporary rearing equipment for the opsariichthys bidens based on circulating water, which can enhance the immunity of the opsariichthys bidens, promote the metabolism of the opsariichthys bidens, improve the meat quality and taste of the opsariichthys bidens, and is favorable for accelerating the flow of a water body so that the interior of a cage body has enough oxygen content.

The technical scheme adopted by the invention for realizing the purpose is as follows: equipment of raising horse-mouth fish temporarily based on circulating water, including the cage body frame, the cage body frame is formed by a plurality of semi-circular stand circle welding, and cage body frame bottom is the level form, and the parcel of cage body frame outside has the net piece wall, and cage body frame right side port connects and stores up the fish bag, stores up the terminal knot of utilizing of fish bag and ties firmly. The design of cage body frame has stronger stability, fastness, and its bottom level, it is big to land the area, is difficult for being washed away by rivers, can satisfy various complicated waters topography, and the net piece wall in the cage body frame outside can make whole cage more firm, and durable is equipped with two and advances the escape performance of preventing that the fish mouth can further increase the cage, and the cage still has extremely strong effect of luring the opsariichthys bidens, improvement by a wide margin the fishing volume of opsariichthys bidens.
