Embodiment example

[0049] Build a 200-square-meter ecological breeding pond, generally 10 meters x 20 meters, with a depth of about 1 meter, and divide it into 3 sections to form a flowing water breeding model;

[0050] A cement platform is built at the beginning of the breeding pond, and two biochemical filter boxes are placed on the platform. The water outlet of the biochemical filter box faces outward, and the water inlet faces the pool wall.

[0051] The bottom of the breeding pond 1 is covered with 10cm-15cm ceramsite. You can choose other biological fillers, such as coral sand. per minute; the stocking density of cultured fish is 6-15 kg / m3; the cultured species is bait fish (such as bream), with an average weight of about 500 grams; bitter grass is a kind of submerged plant, and each flower pot is planted with a bitter Grass settles to the bottom of the pond, preventing its biomass from increasing beyond 30% of the area.

[0052] Construct a miniature artificial wetland—subsurface flow w...

Abstract

The invention relates to aquiculture facilities for removing bilgy odor of fishes, in particular to an aquiculture system for removing the bilgy odor of the fishes. A rectangular aquiculture pond (1) is an S-shaped flow channel pond (2b). At least one biochemical filter box (4) is arranged at the starting end. Three blocks of horizontal partition wall (7) are arranged at the tail end of the tail-section straight flow channel pond (2d) in sequence to form a first water collecting ditch (10), an undercurrent wet land (9) and a second water collecting ditch (8) one after another. A water pump (11)is arranged in the first water collecting ditch (10), and water passes to an inlet of the biochemical filter box (4) through a pipeline (3) and finally flows into the flow channel pond (2d) through an outlet of the biochemical filter box (4). Base materials of a bottom layer of the undercurrent wet land (9) are ceramsite, and aquatic plants are planted on the ceramsite. The bottom of the flow channel pond (2) is coated with the ceramsite which has the depth of 10-15 centimeters and serves as biologic fillers, water plants occupying 30% area are planted in the flow channel pond (2), released density of cultured fishes is 6-15 kilograms/cubic meter, and water flow speed is 3-10 centimeters/minute. The aquiculture system for removing the bilgy odor of fishes is built for creating ecological environment and controlling negative factors influencing the bilgy odor of the fishes.

Description

technical field [0001] The invention relates to a breeding facility for removing the earthy smell of fish, in particular to a breeding facility for controlling the factors directly related to the earthy smell of fish such as algae and actinomycetes in the breeding environment. Background technique [0002] Pond aquaculture aquatic products are the main source of aquatic product supply in my country, but most of the aquaculture aquatic products, especially freshwater carps, have the problems of earthy smell and bad taste. The mechanism of the earthy smell of farmed fish is very complicated, and there has not been a completely consistent opinion so far. Hui Xinyi et al. (2006) showed that the water-soluble flavor components that constitute the earthy smell of silver carp fish mainly include His, Tau, and Lys , Ser, Val, Met, Phe, IMP, Xu Lipu et al. (2007) showed that the earthy smell of grass carp and carp is mainly composed of the secondary metabolite 2-methylisomethanol (MI...
