Embodiment 1

[0022] A kind of factory farming flounder fish breeding pond, such as figure 1 , 2 As shown, the culture pond is a high-level pond, the height of the pond is 2.0m, and the ground area of ​​the culture pond 1 is 15m 2 , 2 perched surfaces are set in the pool.

[0023] The perching surface is made of rigid dark-colored PVC board with a thickness of 2cm and dense small holes 3 with a diameter of 0.5cm and a density of 2000 holes per square meter. The area of ​​the first habitat surface 2 counted from the lower floor is 10m 2 , the height from the bottom of the breeding pond is 50cm, and 12 first support pipes arranged along the edge of the habitat surface. The first support pipe is rivet-welded with the perching surface at 90° vertically.

[0024] There are 12 piles fixed at the bottom of the culture pond 1. The diameter of the piles is equal to the inner diameter of the first supporting pipe 4 in the lower layer. The first supporting pipe is sleeved on the piles. Welding, a...

Embodiment 2

[0026] From 2017 to the first half of 2018, we carried out semi-smooth tongue sole aquaculture production in Tianjin Haifa Zhenpin Industrial Development Co., Ltd., transformed the aquaculture pond, and carried out double-layer treatment. The habitat board is black, the water depth in the pond is 1.5cm, and the layer height is 50cm, set up the habitat surface at the height of 50cm and 100cm respectively, the device effectively increases the habitat area, the overall culture density of the culture pond of the present invention is 32% higher than the normal culture density, and the melanization rate of the eyeless side of the cultured fish is different in different degrees. Low, the highest is 18% lower than the control group, so this breeding pond has important production application value and promotion value.

Abstract

The invention relates to a layered habitat culture pond for industrial flatfish culture, which belongs to the technical field of aquaculture devices. The culture pond is a high-level pond with a height of 1.8 to 2.0 m, the pond is internally provided with more than one habitat, the habitat is parallel with the bottom of the culture pond and a distance of more than 20 cm exists with the bottom of the culture pond. Through adding one to two habitats in the culture pond, a layered structure is formed, the habitat area of the flatfish is effectively increased, and the culture water body is used efficiently.

Description

technical field [0001] The invention belongs to the technical field of aquaculture equipment, and in particular relates to a layered habitat culture pond for industrialized culture of flounder and flounder. Background technique [0002] Over the years, many aquaculture practitioners have been exploring efficient and intensive factory farming models. Limited land, limited workshops, and limited water bodies require us to continuously develop new methods for efficient and intensive production. As a bottom-dwelling fish, flatfish naturally needs a wider living environment. At the same time, under the high-density breeding environment, the growth and development of fish are limited and the diseases frequently occur. How to solve this pair of contradictions is a big problem facing the majority of farming practitioners. [0003] A variety of factors in the environment restrict the growth and development of farmed fish: According to research, factors such as nutrition, light, sub...
