Fodder feeding device for sturgeon larva and control method

Abstract

The invention discloses a fodder feeding device for sturgeon larva and a control method. The fodder feeding device comprises a feed tank suspended on the surface of water, a discharging port with a valve at the bottom of the feed tank is connected with the top of a pyramid through a feeding pipe, the pyramid is formed by connecting a plurality of trapezoidal plates, each two adjacent trapezoidal plates are connected through flexible connecting cloth, and the upper end of each trapezoidal plate is hinged to the lower end of a feeding pipe; a distributing device is arranged on the lower portionof the feeding pipe, and a plurality of intake platforms are arranged on the periphery of the bottom of the pyramid and connected with the distributing device through distributing pipes; the fodder feeding device further comprises a cone vertex angle adjusting device of the pyramid and a controller. The fodder feeding device is highly matched with intake habit of the sturgeon larva, and inclination degree of the trapezoidal plates can be adjusted according to intake conditions of sturgeons to adapt to intake needs of the sturgeons, so that feeding efficiency is high; feeding is uniform, fodderutilization rate is high, and the fodder feeding device has great 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
