Cadrin We used time series, diet studies and angler surveys to examine the potential for conflict in brackish lagoon fisheries of the southern Baltic Sea in Germany, specifically focusing on interactions among commercial and Keywords: recreational fisheries as well as fisheries and cormorants (Phalacrocorax carbo sinensis). For the time period Fish-eating wildlife between 2011 and 2015, commercial fisheries were responsible for the largest total fish biomass extraction Commercial fisheries (5,300 t per year), followed by cormorants (2,394 t per year) and recreational fishers (966 t per year). Com Human dimensions mercial fishing dominated the removals of most marine and diadromous fish, specifically herring (Clupea Conflicts Recreational fisheries harengus), while cormorants dominated the biomass extraction of smaller-bodied coastal freshwater fish, spe cifically perch (Perca fluviatilis) and roach (Rutilus rutilus).
