Abstract

The invention provides a fishery farm. The fishery farm comprises a large farm, a small farm as well as a dam for separating the large farm from the small farm, wherein at least one fish passing channel penetrating through the large farm and the small farm is formed in the dam, so that the large farm and the small farm are ensured to communicate with each other, and activities of fishes in ponds on two sides are facilitated. Valves capable of opening and closing the fish passing channel are arranged in the fish passing channel, and bait feeding devices are arranged in the small farm. When thevalves are switched on, the two ponds communicate with each other, and fishes in the large farm can swim to the small farm via the fish passing channel to take bait, so that unnecessary waste of the bait is avoided, a utilization rate of the bait is increased, environmental loads of the farm on water quality and substrate are reduced, the water environment pollution is reduced; and when the fishestake bait in the small farm, the valves are switched off, and fishing can be carried out in the small farm, so that a large quantity of manpower and material resources are saved.

Description

technical field

[0001] The invention relates to the technical field of farming, in particular to a fish farm. Background technique

[0002] Pond (or reservoir) culture is an important part of the aquaculture industry and plays an important role in fishery production. When breeding in ponds (or reservoirs) with large water surfaces, it is generally necessary to set up many bait delivery points next to the farm. Usually, the amount of feed is large and the utilization efficiency is low. A large amount of unused bait settles to the bottom of the farm. Over time, not only It causes waste of resources, and also brings problems such as excessive nitrogen and phosphorus content in the water body and eutrophication of the bottom of the farm. On the one hand, aquaculture water bodies with excess nitrogen and phosphorus are prone to cyanobacteria blooms and aggravate water environmental pollution; on the other hand, due to the large water surface, it is difficult to concentrate dredg...

Embodiment Construction

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0020] This specific embodiment provides a fish farm, which improves the feed utilization rate of fish culture in large farms, reduces the environmental load on water quality and bottom quality caused by culture, reduces water environmental pollution, and saves manpower and material resources.

[0021] Hereinafter, an embodiment will be described with reference to the drawings. In addition, the examples shown below do not limit the content of the invention desc...
