Abstract

Methods for improving or correcting crustacean breeding methods Crustaceans, especially that shrimp They are marine animals that are often cultured in ponds. Which is often contaminated by pathogenic bacteria And there are also fish that hunt prey, which can eat shrimp. In the pond, the proportion is significantly reduced if not controlled In addition, a good pond must be performed. It also controls the level of phytoplankton. The pond mentioned above can be treated with dilute peracids such as peracetic acid in concentrations below the lethal concentrations. This is to control phytoplankton. And / or bacteria that cause disease as well as can kill prey fish in the pond as well. Generally preferring peracid concentrations in the range of 0.5 to 5 mg / l of peracetic acid. Stick

Claims (2)

1.How to treat living crustaceans And phytophas when the green type Live by adding peracids into the pond For the pond water to have peracid concentrations ranging from 0.5 mg / l to 50% by weight of LC-50 concentration (24 h) for crustaceans. that And preserve the population of green phytoplankton but protect Prevent the spread of the same. 2. Process according to claim 1, with peracid concentrations ranging from 0.5 mg / l up to 50% by weight of LC-50 (at 24 hrs. ) For that type of crussian 3. Process according to claim 1, that is, peracids must contain peracetic acid 4. process according to claim 1, that is, the pond contains sea water. And crustaceans Brine shrimp 5. Process according to claim 4, that is, pond shrimp is P. Monodon 6. Process according to claim 1, that is, peracid pond treatment is performed periodically during 1 to 10 days between each treatment. 7. Procedure according to claim 6, that is, the interval for each treatment is reduced from 7 to 10 days during the crustacean young to 1 to 5 days when the crustaceans have grown enough 8. Process according to claim 1, that is, crustaceans contain shrimp 9. Process according to claim No. 8 that is, in the pond, apart from shrimp, there are also fish and The concentration of peracid was strong enough to kill fish 1.0. The process according to claim 8, that is, in addition to having shrimp in the pond, there are also pathogenic bacteria. And the concentration of peracids in use can prevent the diffusion 1 Bacteria 1. Process according to claim 1 or 8, that is, the concentration of peracids in the pond. Shall not exceed 5 mg / L 1 2. Process according to claim 1 or 8, that is, the concentration of peracids in the pond. Will be from approximately 0.5 to approximately 2 mg / l
