Energy-conservation and consumption-reduction type obliquely-square net cage for cultivating large yellow croakers

Abstract

The invention discloses an energy-conservation and consumption-reduction type obliquely-square net cage for cultivating large yellow croakers, which is used for mariculture. The technical scheme provided by the invention is that the energy-conservation and consumption-reduction type obliquely-square net cage consists of a buoyancy force system and a netting system, and has the characteristics that the buoyancy force system consists of an inside casing and an outside casing, and the inside casing is connected with a first net cage body longitudinal netting through an ultra high strength dyneema rope; the netting system adopts a combination structure netting form of 'a first box longitudinal netting + a second box longitudinal netting + a net cage bottom netting'; the net cage bottom netting is assembled on a pipe support; micropores are punched in a pipe of the pipe support every 1 meter; after being connected with the net cage bottom netting, the second net cage body longitudinal netting extends to an edge line of the net cage bottom netting along netting longitudinally-installed vertical lines from an upper horizontal line of the box longitudinal first netting; a cross lacing line is additionally arranged at the bottom of the net cage, crossed lacing lines are additionally arranged along the diagonal directions of the bottom of the net cage; and a cross point of the two crossed lacing lines along the diagonal directions of the bottom of the net cage is tied by a rope, and a foam float bowl which is externally wrapped by seawater corrosion protection canva and a nylon net is tied by the other end of the rope.

Description

technical field [0001] The invention relates to an energy-saving and consumption-reducing net cage for cultivating large yellow croakers at sea. Background technique [0002] Large yellow croaker breeding cages use synthetic fiber nets and synthetic fiber ropes, resulting in a large consumption of raw materials for the cage rope nets, and serious fouling and adhesion in the production of cage culture, which further leads to poor water exchange inside and outside the cages, and it is difficult to change the nets. The number of times is large and the labor intensity of changing the net is relatively large, which affects the normal growth and development and breeding benefits of large yellow croakers. The net clothing at the bottom of the existing large yellow croaker breeding net cage is easy to float at a high flow rate, causing a sudden change in the shape of the cage body, resulting in a low volume retention rate of the large yellow croaker breeding net cage. During the de...
