Residual feed collecting device for fish culture

Abstract

The invention relates to a residual feed collecting device for fish culture. The residual feed collecting device comprises a feed box body (1), pontoons, a discharging device, a feeding platform and a collecting platform, the discharging device is located below the feed box body and used for conveying feed to the feeding platform, the feeding platform is used for feeding fish in different water layers with the feed, the collecting platform is arranged below the feeding platform, and residual feed is collected and recycled; the pontoons are arranged on the two sides and the lower bottom of the feed box body (1), the pontoons specifically comprise a first left pontoon (41), a second left pontoon (40), a first right pontoon (7) and a second right pontoon (9), the second left pontoon (40) and the second right pontoon (9) are arranged at the lower bottom of the feed box body (1) and can be inflated and deflated so as to control height of a position, floating on the water surface, of the feed box body (1).

Description

technical field [0001] The invention relates to the technical field of aquatic engineering, in particular to a residual bait collection device for fish breeding. Background technique [0002] With the advancement of science and technology, aquaculture is becoming more and more scientific. Aquaculture reproduces, cultivates and harvests aquatic animals and plants under artificial control. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. In current aquaculture, seedlings are generally placed in waters, and then bait and fertilization are used to grow aquatic products. However, the cost of putting in feed is actually very high, and if the feed is not eaten by fish, it will remain in the water , it is harmful to the growth of fish to a certain extent. In the breeding process, automatic feeding and recycling of feed can avoid damage to fish, and can save water and maintain the breeding environment; due to different types of fish Floc...

Problems solved by technology

In current aquaculture, seedlings are generally placed in waters, and then bait and fertilization are used to grow aquatic products. However, the cost of putting in feed is actually very high, and if the feed is not eaten by fish, it will remain in the water , it is harmful to the growth of fish to a certain extent. During the breeding process, automatic feeding and recycling of feed can avoid damage to fish, and can save water and maintain the breeding environment; due to different types of fish Flocks live in water layers of different depths, some live in the upper layer, and some live in the middle layer. If the feed is fed directly, most of the feed may be eaten by the fish in the upper waters, while the fish in the lower waters will eat it. There is very little bait, how to feed the feed evenly and feed fish in different fish layers and recycle the remaining bait in a timely manner is a difficult problem
