The KVK Ernakulam conducted a training program Biological management of Aquatic weeds as part of it’s Swachhata Pakhwada on 27th December 2021 for members of Moozhikulam Sala, a cultural & environmental collective located at Moozhikulam, Ernakulam. Many of the freshwater resources in the district are infected by different types of aquatic weeds and algae resulting reclamation of these precious water resources into waste dumping yards. This not only lowers ground water levels, but also leads to flooding during monsoon. Cleaning of water sources and maintaining them tidy is essential. Rearing herbivorous fishes to feed algae/aquatic weed plants is a viable environmental friendly solution. Grass Carp (Ctenopharyngodon Idella) is an ideal candidate that has ability to feed aquatic weed voraciously about 2 to 3 times of its body weight daily.  Releasing 20 Grass Carps of 500 gm size can manage 1 acre pond.
