Hello! I got this list address from a member of alien-species list because I have a question concerning the abundance of seal species. A possible resettlement of grey seals at the German Baltic coast rises questions on maximal abundances of seals in a definded area as fishery is concerned about the impact of seals on fish populations. Does anyone have experience with population densities (e. g. at haul outs in breeding seasons) in a defined area? Thanks very much!
