Tuna
Targeting tuna off the coast of Groton, Connecticut, demands a commitment to offshore fishing and a keen understanding of seasonal migrations. The waters south of Fishers Island can hold bluefin and occasionally yellowfin tuna during the warmer months, typically from late summer into early fall. Success depends on locating areas with high concentrations of baitfish, such as sand eels or squid. Trolling is a common tactic, using spreader bars or daisy chains to imitate schools of bait. Chunking with butterfish can also be effective when tuna are holding in a specific area. Be prepared to adjust your depth and tactics based on water temperature and current conditions. Consider launching from a marina in Noank or Mystic to gain access to deeper waters. Keep in mind that tuna fishing requires specialized gear and knowledge of local regulations, including permit requirements and size restrictions.
