Stenotomus caprinus is a species of marine, ray-finned fish in the Sparid family which contains seabream and porgies. Found in coastal Atlantic waters off the southeastern United States and Mexico, it is also called the Longspine porgy and the Goat-head scup.

Taxonomy and naming

A figure of S. caprinus, probably based on an earlier drawing, appearing in in Hugh Smith's (1907) Fishes of North Carolina. In this figure, the species is referred to the genus Otrynter.

The Longspine porgy was described by the American ichthyologists David Starr Jordan and Charles Henry Gilbert in 1882.

Etymology

Description

Distribution and habitat

The Longspine porgy is known from the western part of the Atlantic Ocean. In the United States, it can be found in waters off North Carolina, south to Georgia and Florida. In the Gulf of Mexico, it ranges from Florida to the Yucatan Peninsula.

Found over muddy bottoms, as well as some sandy, this species has been captured as shallow as 18m and as deep as 100 m (330 ft), though it prefers to inhabit depts between 36–55 m (118–180 ft).[1] It appears to prefer bays and gulfs, but can be found on the North American continental shelf as well. [2]

Biology

The Cobia is a known predator of Longspine porgies.

Longspine porgies feed mainly on zoobenthos and detritus, though they may prefer to predate on the former [3] [4]. In turn, they are predated upon by the Cobia, Rachycentron canadum. The gills and gill arches of this species are also the namesake host for the monogenean flatworm Microcotyle otrynteri, which was first reported from a Longspine porgy collected off North Carolina in 1949. [5][6]

Spawning occurs in late winter or early spring: from January to April, according to observation in the Gulf of Mexico near Texas. [7] This spawning period probably lasts for approximately 90 days. [7].

Relationship with humans

Considered to be a minor component of both commercial and recreational fishing in the Gulf of Mexico, this species may be facing a population decline. One causal factor of possible decline may be that Longspine porgies often appear as bycatch in shrimp trawling in the Gulf of Mexico.
