Acinetobacter radioresistens jl23 strain and method for fish cultivation

Abstract

A strain of Acinetobacter radioresistant JL23 is disclosed, which is introduced into aquaculture water to solve the problem of ammonia nitrogen accumulation in conventional fish farming methods that require water changes. This Acinetobacter radioresistant JL23 strain is registered at the Food Industry Research and Development Institute of the Republic of China, with accession number BCRC 911301. This invention also relates to a fish farming method using this Acinetobacter radioresistant JL23 strain. This method can improve the health of the farmed fish and increase their survival rate.

Claims

1. A strain of Acinetobacter radioresistens JL23, which can reduce ammonia stress in freshwater farmed fish, is deposited at the Food Industry Development Institute of the Republic of China, with the accession number BCRC 911301.

2. A method for fish farming, comprising: providing a culture water; adding Acinetobacter radioresistant strain JL23 as claimed in claim 1 to the culture water to form a mixed culture water; and culturing a freshwater fish in the mixed culture water.

3. As in request item 2, the fish farming method, wherein, The concentration of the radiation-resistant Acinetobacter JL23 strain in the mixed culture water was 10⁴–10⁶ CFU / mL.

4. As in request item 2, the fish farming method, wherein, The freshwater cultured fish is a catfish.

5. The fish farming method as described in Request 1, wherein, The ammonia nitrogen concentration in the mixed aquaculture water is 15–30 mg / L.

6. The fish farming method as described in Request 1, wherein, The freshwater fish were cultured in the mixed culture water at a temperature of 24–32°C.

7. The fish farming method as described in claim 2, wherein, The pH value of the mixed aquaculture water is 6.8 to 8.3.
