BIOLOGY
Gurnards belong to a group of fish known as the Triglidae (sea robins) family. Classified as a generalist, they are characterised by fast growth and early sexual maturity at a relatively large size. Red gurnard is one of the smallest European gurnards. It spawns in summer. Can attain a length of 40 cm and a weight of about 900g, with a maximum reported age of 21 years. Gurnards are able to grunt or growl by use of muscles associated with the swim bladder, and this is believed to aid in keeping schools together.

CAPTURE OR FARMING INFORMATION

ADVICE
Red gurnard is a fast growing fish and matures early at a large size. Avoid eating immature fish (less than 20cm) and fresh (not previously frozen) fish caught during the spawning season (summer).
