The Blotched Picarel is one of the most common fish of the Centracanthidae family and a close relative of the picarel. The body is taller, broader, and more robust than that of the picarel, with a colour that ranges from leaden blue on the back to silver on the sides. The most characteristic feature is the bold black spot on the side of the body, which in this species is usually square or rectangular, in contrast to the common picarel's rounder spot.

The species exhibits impressive sexual dimorphism. Females maintain a simpler appearance, while males undergo radical changes as they age. Their bodies become deeper, with a pronounced hump, and the black spot often fades or disappears as bright, electric-blue spots and lines cover the head and fins.

This is a coastal semi-pelagic species that forms schools. It lives mainly over Posidonia seagrass meadows and sandy or muddy seabeds. It is encountered at depths ranging from 5 to 150 metres, with schools denser in the zone between 30 and 90 metres. It is active during the day, while it approaches the seabed at night to rest.

The Blotched Picarel is larger than the common picarel. The usual length of females is 12 to 20 centimetres. The males grow noticeably larger and can reach a maximum length of 25 centimetres.

During this period, the males become territorial and dig small nests or hollows in the sandy bottom. After attracting females to spawn, the males fertilise the eggs and take on their care by guarding the nest and aerating the eggs until they hatch.

Fisheries & Economic Value

The fish is caught in large quantities as a commercial catch with bottom trawls, purse seines, and set nets, particularly during the breeding season when the fish gather in shallow waters. Although it has a low commercial value due to its abundance, the meat is very tasty, especially when fried. In some regions, it is traditionally salted and is considered a select delicacy.
