- Although the flesh of the almaco jack is considered quality table fare, the species has been associated with ciguatera poisoning, a seldom fatal stomach irritation.
- The almaco jack is susceptible to tapeworm parasites in the caudal peduncle area, but the meat can be eaten safely if affected portions are cut away.
Littlehead porgy (Calamus)
Littlehead porgy have a compressed, deep body that is somewhat circular in shape. They have a distinct hump on the back just before the dorsal fin. Coloration is mainly silvery highlighted with copper or brass around the edges and throughout the body, especially on the fins. There also are unconnected vertical copper bars on the side. The snout and cheek are bluish-gray and some blue coloring may be present throughout the body.
The tail fin is deeply forked, and the head, as their name suggests, is small and ends in a short snout. They have a small mouth, a fairly long pectoral fin and two, connected dorsal fins, the first with spines and the second with soft rays.
Littlehead porgy are carnivores with a diet consisting mainly of invertebrates. They are not huge eaters, consuming only four times their body weight per year.
Littlehead porgy are found in the western Atlantic from northeastern Florida to the Bay of Campeche (Mexico) on the southern side of the Gulf of Mexico.
Littlehead porgy are an inshore and near shore species that are mostly found over sponge and coral bottom, usually hugging close to the bottom. Though young littlehead porgy are found in shallow waters near shore, adult littlehead porgy are almost always located further out to sea. They seek warm waters at 62 F or above.
