Description

The red porgy is a moderately deep-bodied fish with an oblong shaped body. The standard length is , although a more typical length is about half of this. The dorsal fin has eleven to thirteen spines and nine to ten soft rays while the anal fin has three spines and seven to eight soft rays. This fish is a silvery-pink colour, with darker patches on the nape and behind the pectoral fins. The caudal fin is dark pink with paler tips, and the other fins are pale pink.

Distribution and habitat

The red porgy is found in warm coastal waters on either side of the

s, with most individuals starting life as females and at some point changing sex to males. The fish reach sexual maturity at two or three years of age. The sex change occurs at a wide range of sizes ( TL) and a wide range of ages (two to nine years). Not all fish change sex: some fish are primary males whose ovarian tissue atrophies before they reach maturity, others are secondary males, behaving as females for a few cycles before changing sex, and some remain as females even when large, with only rudimentary male tissue being present. There is some evidence that the timing of the sex change is linked to social or environmental factors.

Status

The red porgy is an important species for both commercial and recreational fishing, especially on the southeastern coast of the United States, Argentina, and the Mediterranean Sea. It is usually taken by rod and line. Populations have declined because of over-exploitation, but in some areas minimum size limits have been set to try to redress this. Stocks have also been augmented by the use of
