Ecology Summary - Scomberomorus maculatus

Language:

Main Ref.	Collette, B.B. and C.E. Nauen, 1983
Remarks	Migrates northward from Florida along the Atlantic coast of the USA to Narragansett Bay, Rhode Island bet. Late Feb.-Jul., and back in fall. It overwinters in Florida. There are schools migrating westwards in early spring, reaching Texas in late March. North-south movements along the Mexican coast occur between Aug.-Nov. and back in Mar.-Apr. Feeds mainly on small fishes (clupeoids and anchovies), few quantities of penaeoid shrimps and cephalopods. Juveniles have a higher percentage of anchovies in their diet than adults. Piscivore (Ref. 57616). Casting, live-bait fishing, jigging, and drift fishing are also employed in capturing this species. Aerial spotting is sometimes used in locating the fish.
