In the article, the period of triphenylmethane dyes (for example, malachite green and crystal violet) removal from the fish’s tissues after treatment is examined. In the Russian Federation, their use in aquaculture was discontinued. No alternative replacement for these drugs was found which led to a worsening of the epizootic situation in fish farms. The established terms for malachite green excretion for rainbow trout are 282 days (10 months), for purple "K" during summer carp breeding - 40 days (1.5 months). The use of these dyes during incubation period and in the first year of fish rearing in compliance with these terms will allow one to get fish products without a residual amount of triphenylmethane dyes. |
