Numerical modelling of the population of grey seal (Halichoerus grypus) from the Baltic Sea in the context of reduction of damage to fishing economy

The work is a source material for organizations dealing with the management of the aquatic environment, including regulating the population of species that pose a real threat to fishermen. Predators, which have no natural enemies in the Baltic Sea environment, including the grey seal, have been part...
