Predatory fish are defined as those that consume smaller fish, fry, and eggs, posing a significant threat to fish populations. These fish are characterized by their relatively large mouths. In aquaculture ponds in Bangladesh, the presence of these predatory fish alongside cultivated varieties like Rui, Catla, or Mrigel can cause substantial damage. This predation impacts fish stock levels and the overall success of fish farming. Farmers in Bangladesh need to be aware of the risk predatory fish pose to their livelihoods. Effective management strategies are crucial to mitigate damage and sustain aquaculture in the region.
