What does croaker mean?
A croaker is, most simply, something that croaks — typically a frog, though ravens and other hoarse-voiced creatures have earned the label too. The word also names a group of North American fish: members of the family Sciaenidae, related to drums and seatrout, which produce croaking or drumming noises by vibrating muscles against their swim bladder. Anglers on the Atlantic and Gulf coasts commonly catch species like the Atlantic croaker (Micropogonias undulatus), prized both as food and as bait. By extension, 'croaker' has occasionally been applied to people — habitual grumblers or, in old slang, gloomy prophets of doom. Informal and somewhat rustic in flavor, the word evokes ponds at dusk and fishing piers at dawn. Its charm lies in its directness: it names things by their sound, making it one of those vivid common nouns that carry a little onomatopoeia inside them.
An animal that croaks, especially a frog.
"A single croaker started up in the reeds just after sundown."
Any fish of the family Sciaenidae that makes croaking sounds, especially the Atlantic croaker (Micropogonias undulatus).
"He filled his cooler with spot and croaker off the Chesapeake pier."
Chiefly North American usage.
Informally, a person who croaks or grumbles habitually.
"Ignore the old croaker in the corner — he complains about everything."
Standard pluralization; used freely for both the animals and the fish.
"At low tide the flats teemed with small croakers."
Some fish literally talk: croakers vibrate their swim bladders to make drumming sounds so loud they were once heard through a boat's hull.

Etymology of croaker
'Croaker' is formed by adding the agent suffix '-er' to the verb 'croak', which arose in English in the fifteenth century as an imitation of the harsh cry of a raven or frog — a classic example of onomatopoeia. Because the verb itself derives from the sound rather than from another root, there are no deep cognate families in Latin or Greek; related forms are simply the verb's own derivatives, such as 'croaky'. The fish sense developed later, from the noise these fish make.
