Atlantic Tomcod

Atlantic Tomcod (Microgadus tomcod) Fish Description

An Atlantic Tomcod is known for its long pelvic rays and rounded tail. It also has dark spots that cover its back and sides. Colorwise, the Atlantic Tomcod appears to be a dark olive gold from the back before turning bright gold towards the middle. Its belly, like most fish, is bright white. The fins are a translucent gray with dark spots all over it. The only fins that don’t have those marks are the Atlantic Tomcod’s pectoral fins which is more of an orange-red color.

Body structure-wise, the Atlantic Tomcod is a slender fish. Despite it being small, the Atlantic Tomcod has three dorsal fins and two anal fins. You’ll notice also right beneath its chin it has a short pale pink barbel.

Diet and Size

Atlantic Tomcods, as winter fish, can survive on a variety of frozen food. They can also handle some freeze-dried food. Atlantic Tomcods also feast on larvae and small crustaceans such as shrimp. They have a taste also for mollusks and fish larvae. They’re also known to eat their own eggs… So much for parental instinct.

Atlantic Tomcods are small. So, most people wouldn’t really catch an Atlantic Tomcod as a gamefish but more as bait. They barely weigh a pound and usually are only 6-10 inches. The longest Atlantic Tomcod ever found was 14 inches.
