Eutrigla gurnardus |
The grey gurnard (Eutrigla gurnardus) is a species of sea robin native to the eastern Atlantic Ocean, the Mediterranean Sea, and the Black Sea. This fish can be found at depths from 10 to 340 metres (33 to 1,115 ft), though it is not normally found below 150 metres (490 ft). This species grows to a total length of 60 cm (24 in), though usually reaching up to 30 cm (12 in).[1] This species is the only known member of its genus.[2]
In Ireland, the fish has been called the cuckoo fish, knoud, or noud.Cite error: The <ref>

Behaviour
As with other sea robins, grey gurnards produce sounds. Sound production in this species is often associated with competition for food. Small individuals produce more sounds than larger ones, and emit more "grunts" than "knocks", probably because they more often compete for food by contest tactics whereas larger specimens predominantly scramble for food.[3]
Fisheries
Grey gurnards are of commercial importance as a food fish.[4]
