including herrings, mackerels, sand launces, and a wide 

 variety of other species. 



Economic Importance: This species is of relatively little 

 importance in the commercial fisheries of the American 

 Atlantic, but attempts are now being made to develop a 

 profitable fishery for it. The Bluefin Tuna is important in 

 the recreational fisheries. Small fish strike at artificial lures 

 trolled in the foamy wake of a vessel. Larger fish are at- 

 tracted to the vessel by scattered ground menhaden and 

 caught on hooks baited with whole fish such as butterfish, 

 mackerel, or menhaden. Fish weighing over 900 pounds 

 have been taken by rod and reel.

 Thunnus atlanticus (Lesson) 



The Blackfin Tuna is known only from the tropical west-

 southern Florida, where it is caught by the sport fisher- 

 men.
