Offshore Blackfin Tuna Fishing Near West Palm Beach

Blackfin Tuna (Thunnus atlanticus) is the smallest member of the true tuna family Scombridae, also known as Deep-Bodied Tunny or Bonite Nore in French. This compact but powerful fish features an oval-shaped body with distinctive black coloration and faded yellow markings near the finlets and sides, making it easily recognizable to West Palm Beach anglers in August.

Blackfin Tuna Overview

Blackfin Tuna are prized by offshore anglers for their incredible speed, strength, and acrobatic fighting ability despite their smaller size compared to other tuna species. These fish inhabit warm offshore waters throughout the western Atlantic, where they form large schools and provide consistent action for charter boats operating out of South Florida ports.

Blackfin Tuna Habitat and Distribution

These tuna prefer offshore waters typically found 3-20 miles from shore in depths ranging from 50 to 300 feet. Around West Palm Beach, they concentrate near temperature breaks, current edges, and areas with abundant baitfish. They favor water temperatures between 68-86°F and are commonly found around weed lines, floating debris, and underwater structure.

Blackfin Tuna Size and Weight

Blackfin Tuna typically range from 7 to 43 inches in length, with most fish caught weighing between 2 and 20 pounds. The average fish runs 10-15 pounds, though larger specimens approaching the maximum size provide exceptional fights on appropriate tackle.

Blackfin Tuna Diet and Behavior

These aggressive predators feed primarily on small fish including sardines, anchovies, and flying fish, along with squid and small crustaceans. They hunt in schools during daylight hours, often driving baitfish to the surface where feeding frenzies create excellent fishing opportunities. Their feeding activity peaks during dawn and dusk periods.

Blackfin Tuna Spawning Season

Spawning occurs in warm offshore waters during spring and summer months when water temperatures reach optimal levels. During this period, fish may be found in slightly deeper waters as they follow temperature gradients and current patterns that concentrate food sources.

Blackfin Tuna Fishing Techniques

Successful techniques include high-speed trolling with small lures, live bait fishing with pilchards or ballyhoo, and vertical jigging over structure. Popular lures include small cedar plugs, spoons, and feathers trolled at 6-8 knots. In August, anglers around West Palm Beach find them responding well to live bait presentations near current edges and temperature breaks where schools concentrate.
