Abstract
A study was carried out for a period 8 months from March 2020 to October 2020 to observe the health status of cultured catla (Gibelion catla) in three Upazilas viz., Khagrachari Sadar, Ramgarh and Mahalchari upazila of Khagrachari district through clinical procedures. Data were collected through personal contact, sampling, questionnaire interview and discussions with key informants. Clinically, Fish from Vhaibonchara and Perachara at Khagrachari Sadar Upazila, Patachara at Ramgarh Upazila were found to be healthy during summer. During rainy season, catla of Mahalchari Upazila were affected with dropsy like clinical signs where major signs were swollen of abdomen, removal of scales and superficial injury. Tail and fin rot affected catla were collected from Ramgarh Upazila having erosion of fins and tail and the presence of white spots in fin and tail region. Cultured catla in rainy season were more affected than those of summer season. However, catla of summer season had reduced clinical changes than those of rainy season. From clinical and pathological point of view healthy catla were noticed in summer and moderately infected in rainy season. It could be mentioned that production and health status of catla were increased in summer season of Khagrachari Sadar area compared with other areas and season. During the study period water temperature were ranged between 23°C to 35°C in summer and 23°C in rainy season. The highest pH was 8.2 ± 0.20 recorded from Mobachari of Mahalchari in summer and the lowest was 6.5 ± 0.25 from the Perachara of Khagrachari Sadar Upazila. Thus necessary measures need to be taken especially during rainy season.
