Classification device applicable to fish aquaculture in rice field

Abstract

The invention discloses a classification device applicable to fish aquaculture in a rice field. The classification device comprises a first classification box, a second classification box and a thirdclassification box which are sequentially and detachably placed from top to bottom, the sizes of the three classification boxes are sequentially increased, openings are formed in the upper ends of thethree classification boxes, the opening of the second classification box is matched with the bottom of the first classification box, and the opening of the third classification box is matched with the bottom of the second classification box. According to a classification mode of the device, fishes can be furthest protected and can actively swim to next classification box under inducing of baits,the fishes are classified, working time is saved, the classification device is applicable to classification in an aquaculture medium term and classification of aquarium fishes and fishes in no hurry to being sold, and the fishes are furthest protected.

Description

technical field [0001] The invention relates to the field of fish breeding and fish separation equipment in paddy fields, in particular to a detachable fish breeding and separation device. Background technique [0002] In the prior art, breeding fish in paddy fields is a relatively popular method that is more beneficial to fish and paddy field cultivation. However, in the cultivation of paddy field fish, when the final catch and sales are carried out, different body sizes need to be harvested. Classify fish of different sizes; sort out some smaller fish, collect some large fish for sale, and in the prior art, the separation of fish is usually sorted manually, and the Classify and separate the size and weight of the fish, and sort them one by one, which is a waste of physical strength and time for the staff; and not only when the fish is caught and sold, it is necessary to separate the fish, but also during the growth of the fish. There will be purposeful classification of f...

There will be purposeful classification of fish and fish size classification in the culture of ornamental fish. This classification usually requires manual classification. On the one hand, it will cause certain damage to ornamental fish and growing fish. On the other hand, it is a waste of time and energy
