Air lift type pond shellfish floating frame culture system

Abstract

The invention discloses an air lift type pond shellfish floating frame culture system. The system comprises a floating frame body, a floating ball support and an air blower support, wherein the floating ball support and the air blower support are both located on the floating frame body; the floating frame body comprises a floating frame bottom plate, floating frame side plates, a first water lifting baffle and a water outlet baffle; the floating frame side plates, the first water lifting baffle and the water outlet baffle are vertically arranged upwards along the edge of the floating frame bottom plate; the floating frame side plates are oppositely arranged on the two sides of the floating frame bottom plate; and the first water lifting baffle and the water outlet baffle are oppositely arranged at the two ends of the floating frame bottom plate. Compared with the prior art, shellfishes are cultured on a floating frame, so that survival competition between the shellfishes and bottom-layer cultured organisms is avoided, later-period shellfish harvesting is facilitated, and isolated shellfish culture is achieved; through the arrangement of a double-lug floating ball, lifting adjustment of the floating frame is achieved; and by means of the air lift principle, while water flow driving is achieved, shellfish culture is completed, and dissolved oxygen of a culture floating frame areaand a pond is improved.

Description

technical field [0001] The invention belongs to the technical field of swimming rings, and in particular relates to an air-lift type pond shellfish floating rack culture system. Background technique [0002] Coastal tidal flats are valuable land resources and a good place to develop tidal flat shellfish farming. Vigorously developing tidal flat shellfish farming not only effectively develops and utilizes land resources, but also provides an effective way for fishermen to change jobs and production. There are many types of tidal flat shellfish produced in my country, about 300 species, of which nearly 50 species have great economic value and have a promising future in breeding and production. The development of tidal flat shellfish farming requires less investment, quick results, and great benefits. Low-input high-yield high-efficiency aquaculture technology. [0003] The growth process of shellfish growth and reproduction under artificial control. Shellfish are generally he...

Problems solved by technology

Shellfish farming in shallow seas does not require baiting, and can be raised in a vast sea; tidal flat farming generally does not need to spend money to establish a breeding ground, and the seedlings can be harvested after 1 to 2 years after stocking. The cost is low and the income is high, but it is limited by dissolution Oxygen, bait and other factors make it impossible to achieve high-density farming. The existing shellfish farming model urgently needs a breakthrough in high-density farming equipment and technology

[0004] In the process of pond culture of tidal flat shellfish, especially in the culture process of razor clams, clams and mud clams, because the phytoplankton in the ponds are easier to cultivate than those in the inner bay of the estuary, the degree of fatness of razor clams, clams and mud clams determines the quality of the culture. In order to benefit, a certain amount of artificial fertilization is usually required, which increases the workload and labor costs of the farmers. While increasing the total amount of bait, it is also prone to the problem of pond hypoxia caused by high biomass, especially due to the razor clams, clams and Clams and other shellfish that adopt the bottom-sowing model are more likely to fail due to high breeding density, and there is competition for the living space of bottom-sowing organisms such as crabs in bottom-sowing culture, which is not conducive to the growth of razor clams, clams and mud clams.
