Cobia are migratory fish and there been studies that have shown some fish moving as many as 15 miles per day over several months. Starting in the spring, cobia can be found migrating from south Florida up north along the Gulf Coast and along the Atlantic Coast up to the Carolinas. Some of the best fishing for cobia takes place in the nearshore waters from late spring through summer and these fish move into some of the most popular saltwater fishing destinations in the country.
Cobia spawn during the summer months at the mouths of bays and in offshore waters. At times, cobia can be found spawning in estuaries and shallow bays. Cobia can spawn between 15 to 20 times over the course of a few months.
