Embodiment

[0013] Example: refer to Figure 1 to Figure 2 , the method for improving the bait utilization rate of industrialized culture, including, wherein: ① preset step: setting the feed circulation maintenance device in the culture pond;

[0014] ②Feeding step: Turn on the inflation device of the feed circulation maintenance device in step ①, and put the bait near the top of the feed circulation maintenance device when feeding the bait. The utilization rate of bait can be high, the amount of aquaculture wastewater is small, and the quality of aquaculture water can be improved. The feed circulation maintenance device includes an inverted conical bait collection net 2; the tip of the bait collection net 2 has an air stone fixing port 5; an air stone 6 is arranged near the air stone fixing port 5; the inner side of the bait collection net 2 is close to the air stone fixing port 5 An upwelling guide pipe 1 is arranged nearby. The air bubbles when the air stone 6 below the upflow guide ...

Abstract

The invention discloses a method for increasing the utilization rate of industrial aquaculture feed. The method comprises the prearrangement step of arranging a feed circulating and keeping device in an aquaculture pond and the feeding step of turning on an inflation device of the feed circulating and keeping device in the prearrangement step and feeding feed nearby the position above the feed circulating and keeping device in the process of feed feeding. The method has the advantages that the utilization rate of the feed is high, the amount of produced aquaculture wastewater is small, and aquaculture water quality is improved.

Description

technical field [0001] The invention relates to a method for regulating and controlling industrialized breeding feed, in particular to a method for improving the utilization rate of industrialized breeding feed. Background technique [0002] Seawater aquaculture is an important part of my country's fishery and agriculture production. At present, seawater factory aquaculture has begun to take shape. In the traditional factory farming of predatory breeding objects, methods such as bait feeding amount control management and feed specific gravity design control are generally used to reduce bait sinking to the bottom; however, such operation management is more complicated and the control is not strict, which will cause a lot of bait waste and Water pollution and other issues, especially for the bait sinking problem in some chilled bait feeding, the current solutions are still relatively limited. In the process of squid breeding, there is no mature feed supply yet, and its bait i...
