BANGLADESH AGRICULTURAL UNIVERSITY, Mymensingh, May 11 (BSS): A new carp breeding ground has been discovered in Kaptai Lake, which is located near Maladwip Point in the Kassalong Channel under Longadu Upazila.
Bangladesh Fisheries Research Institute (BFRI) scientists have discovered the new carp breeding ground near Maladwip Point under Longadu Upazila (Latitude 23.00341438, Longitude 92.194337061), BFRI Publication Officer S M Sariful Islam shared the information on Sunday. "The spawning success rate at the new site was found to be around 90-95 per cent," he said.
Senior Scientific Officer Md. Istiaque Haidar, along with Scientific Officers B. M. Shahinur Rahman, Md. Khaled Rahman, and Md. Lipon Mia, played key roles in identifying the new breeding site and collecting fertilized eggs during the research. During the spawning season, water depth in the Kassalong Channel is ranged from 1.8 to 2.4 meters. Other recorded physico-chemical conditions include water temperature (26.62-27.1°C), salinity (0.01-0.02 ppm), pH (7.28-7.40), and dissolved oxygen levels (5.2-6.6 mg/L)-all of which are favorable for carp spawning.
However, the depth of the spawning grounds has been diminishing due to delayed rainfall and sedimentation caused by climate change. This is affecting the migration routes of brood carp and gradually shrinking their natural breeding grounds.
