Problems solved by technology

However, in industrial farming, due to the bright environment, shallow pool water, and more light transmission, the eyeless side of flounder flounder is inappropriately over-sensitive to light, resulting in blackening of the eyeless side

Embodiment 1

[0021] In 2017, we carried out semi-smooth tongue sole aquaculture production at Xingshenghai Freshwater Aquaculture Co., Ltd., Yangjiabo Town, Hangu, Tianjin, and regulated its body color. The aquaculture pond was transformed, and the bottom and wall of the pond were painted in color. The bottom of the pond was black, and the wall of the pond was black to light gray from bottom to top. The paint height of the pond wall was 1.2cm. An 80w incandescent lamp with a power of 80w is installed above the breeding pond, and the lamp is 1m away from the water surface. After half a year of comparative breeding experiments, the abnormal melanization rate of the eyeless side of the semi-smooth tongue sole in the modified culture pond was 45%, while in the unmodified control pond, the eyeless side melanization rate was as high as 82.7%. figure 1 Therefore, this method can reduce the melanization ratio of the eyeless side of tongue sole, which has important production significance.

Abstract

The invention relates to a culturing pond reducing industrially-cultured-flounder-paralichthys eye-free-side melanism, and belongs to the field of aquaculture. Eye-free-side melanism usually appears in industrially-cultured flounder paralichthys, numerous culturing enterprises are troubled by the abnormal body color problem, and the problem has not been solved. According to the culturing pond, a high-place pond body is arranged, light absorption matter is sprayed onto the bottom and the walls of the pond body for reconstruction, the demersal growing environment of the flounder paralichthys iseffectively improved, eye-free-side melanism of the flounder paralichthys is reduced, and the product price of the flounder paralichthys is remarkably increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a culture pond for reducing the melanization of the eyeless side of flatfish in industrialized culture. Background technique [0002] Like other fishes of the Plaiceidae order, a high proportion of flounder flounder seedlings with abnormal body color often appear in the industrial culture process, that is, partial or complete albinism on the side with eyes and melanization of melanin on the side without eyes. The main manifestation is that the non-eye side is partially covered with plaque pigment, and sometimes it is even completely black, and it occurs to varying degrees in different regions during production. The commercial value of fish with abnormal body color is extremely low, which greatly affects the market sales, and it is easy to be predated by predators, and the survival rate is low. Eyeless melanism occurs widely in turbot, flounder, star flounder, hal...
