Grouper fry breeding box

Abstract

The invention provides a grouper fry breeding box. The breeding box includes a breeding box. The upper end of the breeding box is open and has a cover at one end. One end of the cover is hinged to thebreeding box. The breeding box has a plurality of partition plates. The partition plates divide the breeding box into a chamber I, a chamber II and a chamber III, and the upper ends of the partitionplatesare provided with mounting grooves. Both sides of each mounting groove are respectively provided with drilling holes penetrating through both sides of each mounting groove, and the drilling holes located in both sides of each mounting groove are arranged parallel to each other. Rectangular insertion plates are inserted into the mounting grooves, and the insertion plats are provided with a plurality of matching holes penetrating throughboth sides of the insertion plates. The matching holes and the drilling holes are misaligned.When the insertion platesare pulled up, the matching holes canbe communicated with the drilling holes. The inner walls of one sides of the chamber I and the chamber II are respectively fixedly provided with a plurality of micro-pumps. The micro-pumpsare provided with horizontally-disposed water outlet pipes, and the water outlet directions of the water outlet pipesare toward the drilling holes. Thegrouper fry breeding box has a simple structure and ingenious designand reduces the fratricidalbehavior of the grouper.

Description

technical field [0001] The invention belongs to the field of culture and relates to a culture box for grouper fry. Background technique [0002] Grouper is rich in nutrition, and the meat is tender and white, similar to chicken, and is known as "sea chicken".
