Description

The goldblotch grouper is a robust, elongate grouper of the family Serranidae reaching about 1.4 metres. The grey-brown body is often scattered with small golden spots and, in younger fish, bears a few pale lengthwise stripes on the upper back. Like many groupers the species is a protogynous hermaphrodite: individuals begin as females and may later turn into males. It lives on rocky bottoms, reefs and stony slopes of the Mediterranean and the adjacent eastern Atlantic, where it defends a territory and ambushes fish, squid and crustaceans. The goldblotch grouper is a valued sport and food fish; through its slow growth and fishing pressure its status is Data Deficient (DD).
