Fish egg preservation solution and application thereof

Abstract

The invention relates to the technical field of preservation of fish eggs and larvae, and particularly relates to a fish egg preservation solution and application thereof. The fish egg preservation solution is prepared from the following components in percentage by volume: 0.2%-1% of phenoxyethanol, 4%-5% of propylene glycol, and ethanol and / or glycerol, wherein the volume percentage of ethanol inthe fish egg preservation solution is less than 50%, and the volume percentage of glycerin in the fish egg preservation solution is less than 10%. The fish egg preservation solution can effectively protect the shape of fish eggs and larvae in a long time and protect the fish eggs and larvae in an exposed state from losing water and shrinking and deforming during the identification process, does not damage the DNA of fish eggs and not affect the DNA-based detection, has non-toxic and harmless properties and non-volatile and non-flammable performance, can be used under the simplest laboratory storage conditions and at both normal temperature and low temperature, is safe and reliable, and is applicable in most testing and research units.

Description

technical field [0001] The invention relates to the technical field of preservation of fish roe and larvae, in particular to a fish roe preservation solution and its application. Background technique [0002] Fish eggs are an important way for fish to lay eggs and reproduce offspring in the breeding season, and there are also types of oviviparous and pseudoviviparous. In addition to strict seasonal rules, fish spawning also has fixed spawning sea areas, which are related to various ecological indicators such as water temperature, nutrition, salinity, and plankton richness. Therefore, the type, distribution area and quantity of fish eggs are important indicators for marine environmental monitoring, fishery resource investigation and scientific theoretical research. At the same time, fish eggs and larvae are also the foundation of sustainable fishery development. Their early quantity and survival rate determine the generation replacement of fishery resources, and their quanti...

Problems solved by technology

[0004] In order to overcome the shortcomings of the traditional ethanol preservation solution that affects the morphological identification of fish eggs and larvae due to dehydration and deformation during detection, resulting in color fading, etc., the present invention provides a film-forming, water-retaining, anti-fading effect, The fish roe preservation solution for stable preservation of fish eggs and larvae at room temperature and low temperature. Experiments have proved that the preservation solution of the present invention can more effectively preserve the morphology of fish eggs and larvae than traditional ethanol preservation solutions.
