Abstract/ Executive Summary:

The present study focused on the use of extra-label drugs in commercial aquaculture. Data was collected through questionnaire interview with 30 drug retailers and 30 commercial aqua farmers in Mymensingh Sadar and Trishal upazila of Mymensingh district. All together 94 extra-label drugs of different groups were identified which included antibiotics, disinfectants, nutritional supplements, probiotics, gas remover and saline. Six groups of antibiotics having 10 different active compounds with 46 trade names were found in the drug retailer shops. These drugs were primarily prepared either for the use in veterinary or poultry but were found using indiscriminately in aquaculture. All these drugs were marketed by 18 companies in the study areas. It was observed that 83% drugs were not labeled for aquaculture purpose. Majority (77%) of the commercial aqua farmers used extra-label drugs in their farms and 73% of them never received any prescription from qualified personnel before use. Most of the farmers were unable to calculate appropriate doses and had no idea about risk, safety issue and toxicity reaction of using extra-label drugs. Farmers generally got suggestion from the drug retailer regarding application of drugs. The results also revealed that extra-label use of veterinary and poultry drugs in aquaculture is a common practice by commercial aqua farmers. Thus, the use of drugs in aquaculture should have a sufficient regulatory system in place. It is important to produce and use appropriate labeled drugs under a sufficient regulatory system for safe fish production in the aquaculture of Bangladesh.

Keywords: Extra-label drugs, Antibiotics, Commercial aquaculture

Location: Trishal and Mymensingh sadar upazila under Mymensingh district of Bangladesh

End Date: 00-07-2017

Program Area: Animal Health and Management

Commodity: Aqua Drugs

Objectives:

The objective of the present study was therefore to identify type, source and status of use of extra-label drugs in commercial aquaculture.

Methodology:

The study was carried out in Trishal and Mymensingh sadar upazila under Mymensingh district of Bangladesh for six from February to July 2017. Data were collected from 30 drug retailers and 30 commercial fish farmers through questionnaire interview. The major topic of questionnaire included types, constituents, sources, uses, price and label of drugs. In addition, idea about extra label use, receiving prescription, dose calculation ability and proper application methods were also included. Data were analyzed using descriptive statistics.

Achievement/Findings:

The practice of using drugs and chemicals in aquaculture operations in Bangladesh are not fully regulated and controlled by competent authorities. Hence, the extralabel use of veterinary and poultry drugs in aquaculture is a common practice of commercial fish farmers. The uncontrolled and indiscriminate use of drugs in aquaculture may lead to the emergence of antimicrobial resistant organisms, loses of aquatic ecosystem and make negative impact on human health. Thus, the use of drugs in aquaculture should have a sufficient regulatory system in place. It is also important to produce and use appropriate labeled drugs in aquaculture for safe fish production. Further in-depth research is needed to understand the impact of extra-label drug on fish, aquatic ecosystem and human health.
