Hilsha is our national fish. It provides us necessary protein. Hilsha below 23 cm in length is called Jatka. Catching Jatka is illegal image descriptionaccording to the law. But fishermen catch Jhatka indiscriminately thus creating scarcity of Hilsha in peak season. Bangladesh Navy ships had been operating from 2001 to stop Jhatka catch in Bhola, Haita, Ramgati, Barisal, Pathaghata and adjacent area. Total achievement of Jhatka Operation are shown below:
