Aqua drugs and chemicals used in fish farms of Comilla regions

Abstract

A study was carried out to investigate the drugs and medicine used in aquaculture activities in greater Comilla region in Bangladesh for fish health management and increasing aquaculture production. Questionnaire interview, personal contact, market survey and participatory rural appraisal like focus group discussion were conducted to collect the data. Approximately 138 stakeholders (24 drug companies, 14 drug traders/sellers and 100 fish farmers) were used to collect data from the selected upazilla of Comilla district. Major aquaculture species in experimental areas were monosex tilapia (6%), carps with tilapia (39%), carps with catfish (33%) and combination of carps, tilapia and catfish (22%) respectively. Among the total responded (rotenone 11%, bioaqua 6%, zeolite 33% and lime 50%) used for pond preparation and water quality management; (Bleaching 28%, EDTA 39%, formalin 11% and potash 22%) used as disinfectants; (ACI-OX 28%, oxymax 22%, oxy more 11%, oxy flow 22%) used as oxygenation into water; (lime 56%, salt 11% and potash 33%) used for disease treatment to fish; (oxytetracycline 44%, cotrim-vet 17%, amoxicillin 28% and chlortetracycline 11%) as antibiotics for disease treatments to fish; (aqua boost 28%, AQ grow-G 17%, Eon fish grower 22% and vitamin premix 22%) used as growth promoter; (aqua photo 28%, profs 39% pH fixer 22% and other 11%) used as probiotics and (ammonil 33%, bio-aqua-50 22%, gasonex plus 11% and others 17%) used as toxic gas reducer in the aquaculture pond in Comilla regions. This research findng will help to fish farming community to know the appropriate dose and administration methods for safe and sustainable aquaculture practices.
