IdentificationThe body of weakfish is slim and shaped somewhat like a trout's. The lower jaw projects beyond the upper jaw. There are two large, protruding canine teeth in the upper jaw and no chin barbels.
Its coloring is dark olive or greenish to greenish-blue on the dorsal surface and blue, green, purple, and lavender with a golden tinge on the sides. Numerous small black spots speckle the top, occasionally forming wavy diagonal lines. There is sometimes a black margin on the tip of the tongue.
The weakfish is distinguished from the closely related spotted seatrout because its spots do not extend onto the tail or the second dorsal fin and are not as widely spaced. The scales also do not extend onto the fins on the weakfish.
