Egg holder for fishery breeding

Abstract

The invention discloses an egg holder for fishery breeding. The egg holder comprises a plastic film layer and a nutrient layer, wherein the plastic film layer is an air bubble film; the nutrient layeris laid on the plastic film layer; and the nutrient layer comprises the following components by weight: 1 to 1.2 parts of serum, 0.8 to 1 part of milk and 1 to 1.1 parts of an EM original liquid. Theegg holder provided by the invention can be used for placement of brooded eggs taken out after death of shrimp and crab parents, so the eggs can continue to develop until rupture of membranes is successful, and sufficient nutrients are supplied for the eggs; and the egg holder provided by the invention can float on the surface of water and does not sink down, so demersal eggs on the egg holder donot sink down, and the hatching success rate of the eggs is improved.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a fish farming egg tray. Background technique [0002] In the breeding process of fish fry, a large number of fish eggs are used for breeding. During the breeding process, a large number of existing fish eggs are accumulated at the bottom of the incubator, resulting in accumulation and extrusion, which greatly reduces the hatching rate and survival rate of fish eggs. Some hatchings cannot provide nutrients for fish eggs, so that some fish eggs die due to lack of nutrients during the hatching process; Can not make the ovum after parent's death continue to develop, cause the waste of a large amount of useful hatching crab shrimp eggs. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies, and to provide a fishery breeding egg tray. [0004] A kind of fish farming egg tray provided by the present invention compr...
