In a rare and astonishing event in the deep Bay of Bengal, around three maunds of hilsa fish reportedly jumped directly onto a cargo vessel without the use of nets. The incident occurred about 70 kilometers off the coast near the first buoy of the Rabnabad Channel at Payra Port in Patuakhali. Crew members of the coal-carrying vessel MV KSL Gladiator witnessed the unusual phenomenon as schools of small hilsa suddenly leapt from the sea onto the ship’s deck, resembling a silvery rain. Ship engineer Robiul Hossain captured a short video of the event and shared it with journalists. Marine science expert Dr. Rajib Sarkar from Patuakhali Science and Technology University explained that the behavior might have been triggered by predatory fish chasing the hilsa, combined with the ship’s lights, vibrations, and propeller noise, which could have disoriented the fish and caused them to leap upwards. The sailors described the experience as a once-in-a-lifetime sight.
