Method for inhibiting filamentous bacteria in hatching chamber of shelled artemia spawn

Abstract

The invention relates to a method for inhibiting filamentous bacteria in a hatching chamber of a shelled artemia spawn and belongs to the technical field of microorganisms. The invention solves the problems of the prior art that due to the influence of the filamentous bacteria, artemia spawn is low in hatchability and hard to separate, moreover, when nauplius is fed, fries of fish and shrimp may be infected by bacteria. The method comprises the steps of firstly setting a temperature of a hatching barrel in the hatching chamber and an air charging system, then adding artemia spawn which is shelled in advance into the hatching barrel, next, adding a filamentous bacteria inhibitor into the hatching barrel, and separating the nauplius pure after hatching. The method for inhibiting filamentous bacteria in a hatching chamber of a shelled artemia spawn is mainly used for inhibiting the growth of the filamentous bacteria.

Description

technical field [0001] The invention relates to a method for inhibiting filamentous bacteria in hatching rooms of shelled Artemia eggs, belonging to the technical field of microorganisms. Background technique [0002] Artemia eggs are still irreplaceable as bait for young fish and shrimps. Based on the use of Artemia eggs, we found that filamentous bacteria play a key role in restricting the incubation and use of Artemia eggs. Filamentous bacteria affect its use in the following aspects: First, it affects the hatching rate of Artemia eggs. Since the incubation temperature of Artemia eggs is above 27°C, it is also a suitable temperature for the reproduction of filamentous bacteria. Even if the eggs pass through Shelling treatment also tends to multiply filamentous bacteria in large quantities during the incubation period, causing bacterial infection of Artemia eggs, the hatching rate of Artemia eggs will be significantly reduced, and the production cost of seedlings will be i...

Problems solved by technology

Filamentous bacteria affect its use in the following aspects: First, it affects the hatching rate of Artemia eggs. Since the incubation temperature of Artemia eggs is above 27°C, it is also a suitable temperature for the reproduction of filamentous bacteria. Even if the eggs pass through Shelling treatment can easily multiply filamentous bacteria during the incubation period, causing bacterial infection of Artemia eggs, the hatching rate of Artemia eggs will be significantly reduced, and the production cost of seedlings will be increased.

The second is to affect the separation. After the filamentous bacteria multiply, unhatched dead eggs and empty shells will breed a large number of filamentous bacteria, which are generally suspended in the hatching bucket in the form of agglomerates and mixed with the hatched nauplii. , nauplii are extremely difficult to purify and isolate

Third, filamentous bacteria are easy to infect hatched nauplii. Once fed, it will cause bacterial infection of fish and shrimp fry, which will seriously affect the survival rate of seedlings.

In addition, it is also easy to cause pollution of seedling water, which also threatens the quality of seedlings.
