The decline in fish stock following the killing of otters in Poland can be attributed to the ecological role that otters play in maintaining the balance of aquatic ecosystems. Otters are apex predators that help control the population of smaller fish species, thereby preventing overgrazing of aquatic vegetation and ensuring a healthy fish population. With the removal of otters from the ecosystem, there is a disruption in the natural predator-prey dynamics, leading to an increase in the number of smaller fish species that can potentially deplete the fish stock.
