A survey was undertaken to examine the accessibility of aqua-drugs and their applications in the semi-intensive aquaculture farms in Patuakhali district. A total of 83 stakeholders were selected and data gathered from aqua-medicine stores, representatives of different pharmaceuticals and semi-intensive aqua-farms owners via questionnaire interviews. PRA tools like focused group discussion, cross-checking, and key informant interviews were also used. Results show that 78% of farmers conduct polyculture and rest executes monoculture. Among the total fish farmer majority, 38% used lime for pond preparation and water quality management and potash used by 44% farmer as a disinfectant. For increasing dissolve-oxygen Oxy-rich (26%) was vastly used while 28% of farmers don’t use any oxygen supplier in their pond. However, 14% of farmers use commercial Megavit-Aqua growth promoters and 14% farmer used probiotics. For disease control, 52% and 14% of farmers use Renamycin and Renamox respectively due to its easy availability and affordability compared to probiotics. Several issues have been reported due to improper use of aquatic medications, such as lack of information about chemical use, sufficient dosage, form of application and indiscriminate use of antibiotics. This research result will help the policymaker to understand the requirement of fishers for healthy and sustainable aquaculture practices.
