Abstract:

A study was conducted to know the present status of chemicals and aqua-drugs used for freshwater fish health management in Rangpur district. Data was collected via questionnaire survey, individual communication, FGD with fish farmers, company representatives and chemical sellers from May to October, 2019. All interviewed farmers had farming experience (1-24 years) and 76% had training experience (1-160 days). About 37% of fish farmers used chemicals for treating fish seeds before releasing. Several water quality problems were faced such as dissolved oxygen deficiency (95% of farmers), high ammonia (74%), algal bloom (37%), turbidity (28%), pH (19%) and poor phytoplankton (14%). About 88% of the farmers are facing a number of disease problems like EUS (69.32% of farmers), tail and fin rot (59.09%), argulus (55.68%), gill rot (43.18%), dropsy (42.05%) and exophthalmia (13.64%). Lime (100% of farmers), potassium permanganate (52%), salt (61%), phitkari (21%), copper sulphate (16%), urea (86%) and TSP (86%) were used as traditional chemicals. Sumithion (30.19%), engreb (18.87%) etc. for removal of undesirable species; aquapure (24.24%), biopond (19.70%), zeofresh (18.18%) and many others for pond preparation and water quality management. To increase oxygen concentration oxymax (22.08%), oxymore (18.18%), oxylife (12.99%) etc. were used; harmful gasses were reduced by applying gasonil (28.36%), gastrap (19.40%) and others. Timsen (39.24%), virex (17.72%) etc. as disinfectants; renamycin (29.58%), eskamycin (16.90%) as mainstream antibiotics. Aquazyme (26.92%), panvit aqua (23.08%) were used as growth promoters; pond care (30.56%), profs (22.22%) etc. as probiotics. Therefore, it can be concluded that various aqua drugs were available in the study area and farmers used those to maintain water quality and fish health and to treat several diseases.
