An anesthesia device for classification before fish body measurement

Abstract

The invention discloses a classification and anesthesia device before fish body measurement. An elastic steel sheet is used to set up a group of classification inclined plates with two lower ends close to each other. After the fish body is put into the classification inclined plate, two results will appear. If the body weight is too large, the group of sorting inclined plates will be stretched and dropped down, or if the fish body weight is small, it is difficult to spread the group of sorting inclined plates and slide to the right and downward along the inclined direction of the carrying plate, so that the fish can be realized. The body is classified by its own weight, which is convenient for larger fish to enter into higher concentration anesthesia solution for anesthesia, and smaller fish into lower concentration anesthesia solution for anesthesia, so as to avoid smaller fish from falling into higher concentration anesthesia Death occurs in the liquid, or a longer wake-up time is required, which prolongs the entire fish body measurement time, especially when multiple sets of classification inclined plates with increasing elastic deformation capacity are set up, more accurate fish body classification and anesthesia can be achieved.

Description

technical field [0001] The invention relates to the technical field of fish body anesthesia, in particular to an anesthesia device for classifying fish body before measurement. Background technique [0002] In the process of fish growth, it is generally necessary to regularly take out multiple fish samples for measurement, which is convenient for monitoring the growth of fish. However, if the number of fish samples to be measured is large, before the medicated bath is anesthetized, it needs to be collected in batches. The fish is anesthetized in a medicated bath. Since the anesthesia time is positively related to the fish body weight, it is necessary to manually identify the size of the fish for classification and sorting. The work is tedious, and it takes a long time to complete the collection of large-scale sample data. During the sorting process, it is easy to throw the small fish into the high-concentration medicated bath anesthesia solution, causing the small fish to di...

Problems solved by technology

However, in the later use process, we found that the anesthesia we designed can only achieve one classification, and it is difficult to achieve multiple classifications. In actual use, because the growth of fish is prone to unevenness, multiple classifications can be achieved at one time. , can achieve more accurate classified anesthesia, and facilitate the release of fish after body measurement
