Rare Fish Records

Black-faced Blenny

It is not a true blenny and belongs to the family Tripterygiidae. Fish of this family are small and inhabit rock crevices below low water mark in much the same way as many of blennies do. However, they have three dorsal fins and scales, whereas true blennies of the family Blenniidae have a single dorsal fin running the length of its body and have a mucus covered skin. Exactly how common, or how rare, the British Black-faced Blenny is can only be ascertained by divers' reports. They may have to be searched for because they are secretive. They are also highly territorial and will stay in an area of about 3 square metres. Wheeler reports the British species growing to a length of 68 mm. Two pairs have been seen in the Fleet along with Corkwing and Ballan Wrasse and Tompot Blennies.

Postscript (1998): the scientific name for both species is now Tripterygion delaisi.

Bluemouth

October 1997. A Bluemouth Rockfish, Helicolenus dactylopterus, was caught off Guernsey.

15 July 1997.  A Bluemouth Rockfish, Helicolenus dactylopterus, was caught by a bean trawler 8-10 miles west of Guernsey. (Richard Lord Report).

Triggerfish

Chris Clark has caught Triggerfish on many occasions on rod and line. All captured specimens are returned which is certainly becoming the practice amongst sport anglers. Chris reports that the fish fight hard and are very hardy and returns are likely to have a 90% survival rate.

There are several mysteries surrounding the behaviour and occurrence of this fish in British seas. Chris, who as an angling writer, has many contacts around these islands and lives in Hampshire, assures me that Triggerfish congregate before returning west to warmer waters in late September.

The second puzzle is their path of arrival. Peter Glanvill, in the article in the Winter 1995 issue of Glaucus, thought that the fish followed the northern English Channel coast eastwards and settled around wrecks and rocky outcrops. Records from Cornwall are always earlier in the year. There are very few records from the Brittany coast but there are not many areas where the fish can be caught by anglers from the shore in France.

As this spring has been cold it will interesting to hear of the first reports of Triggerfish caught this year.

Comber

This is true of the Comber, Serranus cabrilla, which is a member of the Bass family Serranidae. It is quite common in the Mediterranean Sea but uncommon north of the Bay of Biscay. However, this fish was juvenile which backs up claims of a population breeding in the English Channel. Adults attain a length of 30 cm. It usually lives on or around the sea bed at depths of 20 metres or more. It feeds on smaller fishes, crabs and prawns and anything else available.

Identification proved to be a bit of a problem at first. The fish was described as reddish with brownish blotches. It had 11 spiny spines on the first dorsal fin preceding a soft-rayed second dorsal fin. This is effectively reduced the possibilities to two fish, the Comber and the Bluemouth, Helicolenus dactylopterus. Although, colour is often a misleading guide to the identity of the fish. the Bluemouth is distinguished by a blue mouth which is easily noticed on close inspection (this ignores the possibility that fish of this species without a distinctive blue mouth are overlooked or mistaken for another species). However, the Bluemouth belongs to the family Scorpaenidae and these fish are more obviously bottom dwellers with a large eye and a keeled spiny head and very much like the common Bullhead, (sometimes called the Sea Scorpion) Taurulus bubalis, on initial appearance, but with a different dorsal fin arrangement. 

Opah

The Opah is the only fish in the family Lampridae. It usually inhabits deep mid-ocean waters at depths of over 100 metres. All its fins are blood red including the long pectoral (side) fins. Specimens of up to 73 kg are rarely captured in fishing gear, with exceptional specimens recorded to 250 kg. It is a predatory fish of this little explored ocean region where it feeds on hake, blue whiting and squids. 

31 October 1998
A rare sea fish which has only been landed in Britain four or five times in the last 20 years   has recently been preserved by the Truro self taught taxidermist Kenny Everett which took   him three weeks to complete. The fish was a Louvar, Luvarus imperialis, which bear some resemblance to the   members of the tunny family but is placed in a family of it’s own the Luvaridae  It was  caught off Newlyn in August, bought by Smart’s the fish merchant of Newlyn who    commissioned the work by Mr.Everett. and will now form part of Smart’s growing    collection of strange and rare fish. The Louvar was 4ft long but can grow to 6ft or more .   It is a most striking fish, deep bodied, with a high almost vertical profile and a brilliant pale   pink lower body and deep blue above. The fins are scarlet except that the tail fin is deep blue with reddish tinges. The adult is totally different from the young fish which goes    through several characteristic stages of development and this has led to several of these    stages being recognised at some time as distinct species, or even genera, of fishes.. Only   adults have occurred in northern European waters although it has a world wide distribution   in warm temperate seas but not reported on tropical waters on either side of the equator.   They have a toothless small mouth and feed on jellyfish and the like. It is known to breed in the Mediterranean where many of the highly variable young stages have been captured,    but many details of its life history are yet unknown.

  I received an e-mail from Andy Horton about your request for information on the Luvar landed at Newlyn. This is as much as I know about it. The Luvar was landed in August 1998 and sold at Newlyn Market to Smart's the local Fish Merchant who commissioned Kenny Everett a taxidermist of Truro to preserve and stuff it. I understand that Smarts have a display of unusual fish at their establishment and this one was due to join them.

Oarfish
 
 

9 May 2010
A rarely recorded Oarfish (or Ribbon Fish), Regalecus glesne, was found dead in the small fishing village of Bovallstrand on the west coast of Sweden, about 90 kilometers (56 miles) from the Norwegian border and on the eastern shore of the Skagerrack. This strange elongated deep sea fish measured 3.5 metres. This was a relatively small specimen of the longest fish found in the oceans. The fish was taken to the House of the Sea Museum in Lysekil. The last recorded discovery of an Oarfish in Sweden was in 1879.
Kurt Ove Eriksson, who discovered the fish, initially thought the behemoth was "a big piece of plastic."

1 February 2009
An unusual discovery washed up on the shore at Hauxley near Amble in Northumberland on the north-east coast of England was the decaying remains of an Oarfish (or Ribbon Fish), Regalecus glesne,. This is a deep water species and the longest fish found in the oceans reaching a length of 11 metres. The last known British record was from Skinningrove, Cleveland on the north-east coast in 2003.
