Description

A land-based permeable farming device

technical field

The utility model relates to the technical field of aquaculture, in particular to a land-based permeable culture device.

Background technique

At present, there are mainly two types of fish farming devices: shallow sea cages and land-based soil ponds. Among them, the shallow sea cages have a large amount of culture, are stable, can be moved, have certain flexibility, and are disposable. The investment is large, and the natural resources of the ocean can be fully utilized. However, in the sea area, it is greatly affected by wind, waves, red tides, etc., and the distance between the bottom of the cage and the seabed

There is a certain distance between them, and the fish cannot continue to use the sinking bait, resulting in waste of feed and eutrophication of the environment;

Earthen ponds are located on land, with low breeding output and relatively small scale. Frequent water changes are required to ensure relatively constant water quality. Water intake and drainage devices need to be built. Such a process requires large energy consumption and high breeding costs.

The method for increasing fish culture in shallow seas is mainly to use suspended artificial net cages, suspended in water bodies, for artificial cultivation, and artificial bait feeding for controllable cultivation. Due to the great human factors, in order to maximize the benefits, a large amount of seedlings are often invested, the density of breeding is high, and the activity space of fish farming is small. Therefore, in the breeding process, a large amount of residual bait, excrement and metabolic waste directly Entering the aquaculture water body, leading to eutrophication of the environment, has become a major problem. Purely relying on the single nutrition of the feed often leads to the lack of nutrition of the farmed fish, which is an important factor leading to the poor quality of the individual farmed fish. The individual commercial fish that grow fish have shallow body color, poor body shape, poor physique, and low price. In addition, artificial fish reefs are used to gather fish schools under natural conditions, the food they eat is nutritious, there is a large space for activities, and the quality of individual fish is excellent. It is possible to realize the breeding of the population to restore the wild population. Due to the small number of human factors, it is an uncontrollable way, 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. How to learn from each other will become the development direction to guide the shallow sea farming model.
