Feed feeding device and control method for sturgeon larvae

Abstract

The invention discloses a feed feeding device and control method for sturgeon larvae, which comprises a feed tank suspended on the water surface, and a feed outlet with a valve at the bottom of the feed tank is connected to the top of a pyramid through a feeding pipe. The pyramid is composed of several trapezoidal plates connected by a flexible connecting cloth between two adjacent trapezoidal plates. The upper end of the trapezoidal plate is hinged with the lower end of the feeding pipe. There are several feeding platforms, and the feeding platform is connected to the feeding device through a feeding tube, and the feeding device also includes a pyramid angle adjusting device and a controller. The feed feeding device of the present invention is highly compatible with the feeding habits of sturgeon larvae, and the inclination of the trapezoidal plate can be adjusted according to the feeding conditions of the sturgeon to meet the feeding needs of the sturgeon. The feeding efficiency is high, the feeding is uniform and the feed utilization is high. High efficiency and high practical value.

Description

technical field [0001] The invention relates to the technical field of fish breeding, in particular to a feed feeding device and a control method for breeding sturgeon larvae in large water surface cages. Background technique [0002] As high-quality protein, aquatic products are more and more popular among people, and their proportion in people's dietary structure is increasing year by year. Over the years, aquaculture has become the main source of global aquatic product supply with its huge development potential. In 2018, my country's total aquaculture output exceeded 50 million tons, accounting for more than 78% of my country's total aquatic product output. It is the only major fishery country in the world where the total amount of aquaculture products exceeds the total amount of fishing. Sturgeon, that is, fish of the order Sturgeon, is a large fish that spawns and reproduces in rivers and rivers. There are 27 species in 2 families, 6 genera, and 27 species in the world...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that its feed feeding device does not match the habit of the sturgeon larvae when the cages of the prior art are cultivating the sturgeon larvae, and there are problems of time-consuming, laborious, low feeding efficiency, uneven feeding, and low feed utilization rate. The problem is to provide a feed feeding device and control method for sturgeon larvae, which has the characteristics of high adaptation between the feeding device and the habits of sturgeon larvae, saving time and effort, high feeding efficiency, uniform feeding and high feed utilization rate
