Fish selector

Abstract

The invention belongs to the technical field of artificial fish farming equipment, and particularly relates to a selector for selecting fish in the processes of artificially farming alepidote fish such as sea eel, Asian swamp eel and misgurnus anguillicaudatus and hard-fin fish such as maccullochella peelii. The selector includes a main box, a selecting sieve and a fish discharging pipe; the selecting sieve is composed of an outer frame and sieve ribs, and the section of the sieve ribs is in a long oval shape or a flat oval shape; when fish are selected during spraying of spray water from thetop of the selector, the fish bodies are sufficiently lubricated and guided, the irritability of the fish is reduced, and the situation is avoided that after getting away from water, the fish strugglevigorously on the selecting sieve and are twisted in traditional tiny sieving ribs, and accordingly epidermis damage and the irritability are caused; in this way, it is easy for the fish which do nothave fins, have fierce temperament and easily struggle vigorously when getting away from the water to intactly pass through sieve gaps, the sieving efficiency is improved, disease infection which iscaused by the epidermis damage and the irritability after selection is reduced, and the quantity of fish dying from oxygen deficiency is reduced.

Description

technical field [0001] The invention belongs to the technical field of artificial fish breeding equipment, and more specifically relates to a kind of artificial breeding eel, rice field eel, loach and other scaleless fish and Australian dragon stripe and other fish with hard fins in the process of sorting different specifications of fish The selector used when. Background technique [0002] Eel, also known as white eel, white eel, river eel, eel, green eel, wind steamed, Japanese eel, is a fish, like a snake, but without scales, generally produced in the sea at the junction of brackish and fresh water.
