High-throughput fry online counting device and method

Abstract

The invention relates to the technology of fishery breeding equipment, and aims to provide a high-throughput fry online counting device and method. The device comprises a fish fry observation channel, camera shooting equipment, a supporting frame and a fish fry temporary storage track. A water outlet is formed in the starting end of the fish fry temporary storage track; the fish fry observation channel is obliquely fixed to the middle of the supporting frame and connected with the fry temporary storage rail through a bent rail. The tail end of the fish fry observation channel is connected to the fish fry outlet section which is located on the lower portion of the supporting frame. The top of the fish fry temporary storage track is open, and the tops of the bent track, the fish fry observation channel and the fish fry outlet section are all in a closed state. Fry separation is carried out through the smooth bent rails and the slope channels, the fry passing speed is increased, the fry flux in unit time can be increased by several times, and scratching damage to fries is reduced; real-time online continuous counting of large-batch fries can be realized, the fry counting efficiency is improved, and the influence of false detection and missing detection on the counting accuracy is effectively reduced.

Description

technical field [0001] The invention relates to fishery breeding equipment technology, in particular to a high-throughput fry online counting device and method. Background technique [0002] As an important part of scientific baiting, fry survival rate assessment, breeding density control, fry sales and purchase, accurate estimation of fry quantity has gradually become the basic guarantee for standardized and scientific management of fish farming. With the development of modern fishery, the level of mechanization and intelligence of my country's fish farming industry has been continuously improved, and the demand for high-throughput automatic counters in fish farming is increasing. However, at present, traditional counting methods such as calculation Method, bowl method, bay method, etc., not only time-consuming and laborious, but also easy to cause survival pressure on fry. Fishery and metering professionals at home and abroad have already conducted research on fry counting...

[0005] Chinese Invention Application Publication No. CN110766123A discloses a fry counting system and a fry counting method. An output port is provided at the bottom of the fry water tank to be tested for a plurality of fry to enter the one-way waterway, and images are collected and counted in the one-way waterway, but In the actual operation process, fish fry swim randomly and like countercurrent, and may not enter the one-way waterway in time, which affects the counting efficiency, and the size of the one-way waterway is fixed, and the suitable fish fry size is limited
