Mote Marine Laboratory

Dr. Locascio's research at Mote is focused on the population structure of adult snook on the beaches and offshore of the Charlotte Harbor barrier islands and he is especially interested in studying the role of the offshore adult snook and how they may be connected to the inshore portion of the population; whether they live, reproduce and die offshore or if they mix with the inshore fish. Understanding these aspects of the population is important.
