Problems solved by technology

The second is to use natural conditions to place artificial fishing reefs to gather fish, and basically do not cast bait. Fish rely on the natural food chain to achieve individual increase and population breeding, so as to restore the wild population. Due to the small number of human factors, it is artificial control method, the density of breeding is low, and the benefit is poor, but for the raised individual fish, the quality is high and the value is great

Embodiment 1

[0032] Step 1. Placement of the breeding device: select the land-based coastline L with an opening at one end as a natural barrier, and intercept the opening with a seine 1 to form a confined water area for the growth of adult fish; two ends of the seine 1 are respectively provided with two The steel cables 3 used for fixing, the steel cables 3 are separated and connected with the fixed object 2 on the land-based coastline L, and the seine 1 is connected with the seine piles 4 distributed at intervals at the opening of the land-based coastline to cooperate; the seine The upper end of 1 is provided with a float 5, and the lower end of the seine 1 is provided with a weight 6, the seine 1 is opened to form a net wall under the buoyancy of the float 5 and the gravity of the weight 6, the float 5 floats on the water surface, and The heavy drop 6 sinks into the seabed together with the lower end of the seine 1; the risk of escape of finished fish due to damage to the seine is minimiz...

Abstract

The invention provides a land-based water-permeable ecological fish culturing method comprising the following steps of: placing a cultivation device, primarily domesticating adult fish, adding the adult fish, carrying out daily monitoring, capturing finished-product fish and recycling the cultivation device. A natural barrier is formed by utilizing a land-based coastline; a cultivation region is enclosed by a surrounding net and the land-based coastline; the cost of a current net box production method is reduced; an activity space and the possibility of fishes are increased and the economic benefits of individuals are improved; artificial management elements are added, the density of a natural space is improved and the output of a unit area is increased; artificially-cultivated large yellow croakers are wildly domesticated in natural sea area provided with the cultivation device, so that the bodily forms of the artificially-cultivated large yellow croakers become thin, the fat is reduced, and the meat quality and the mouth feel are closer to those of wild large yellow croakers; and therefore, the economic value of the artificially-cultivated large yellow croakers is improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for land-based permeable ecological fish farming. Background technique [0002] At present, there are two types of fish farming methods. One is the fully artificial and refined farming method, that is, it is carried out in shallow sea fish suspension cages or pond culture devices. Due to the high density of seedlings, artificial feeding is required. To supplement the nutritional needs of farmed fish, it belongs to controllable farming. Due to the great human factors, in order to maximize the benefits, a large number of adult fish are often invested, the density of the unit water body is high, and the space for the activities of the farmed fish is small. Poor, poor quality, low price. The second is to use natural conditions to place artificial fishing reefs to gather fish, and basically do not cast bait. The fish rely on the natural food chain to realize the increas...
