weakfish

noun

Etymology: Calque from Dutch weekvis, weekvisch (“weakfish”), equivalent to weak + fish, because of its tender mouth.

1. Any of several species of game fish, of the genus Cynoscion, found in North American waters.

   “Weakfishes have no adipose fin, such as fresh-water trouts possess:[…].”

   “Larger fish tend to migrate farther north than smaller ones; thus, the New England weakfish fishery may possess a higher percentage of large individuals than is characteristic of the coastwide fishery. Weakfish tend to move about in schools of similar-sized individuals.”
