Trachurus trachurus

(Linnaeus, 1758)


Jon Chamberlain Could anyone confirm these are Horse mackerel (Trachurus trachurus)? They were in a school of about 30 hovering around me for most of the dive between 6-8m at Salthouse (chalk reef), Norfolk a couple of weeks ago. Dawn says we do get them but not this time of year.

Erling Svensen Yes, they are for sure.

Douglas Herdson Certainly are Trachurus. when is the more usual time in Norfolk?

Andy Horton FISH ID QUERY Dan Worthte: Sun, 29 Jul 2012 14:08:20 +0100 From: dave.gornall@btinternet.com Subject: Strange Fish Help. To: enquiries@glaucus.org.uk; glaucus@hotmail.com Fish caught off the Western Isles, Scotland Hi Andy, we spoke earlier about my unidentified catch, you asked for details, so I'm going to use the attached pic of a Gunard to help me describe certain parts of the fish. The first dorsal fin was very similar, perhaps more triangular. The second again was very similar but not so spikey. The tail fin was slightly shorter and had a more pronouced V, not quite like a mackerel, but perhaps half way. The pectoral fins again were very similar, but perhaps a little smaller (although not much) and with a more rounded edge shape. The anal fin was again very similar and again less spikey. There were no "legs" The overall shape was less gunard and more a lean seatrout shape. The rear of the fish (from about the start of the anal fin) had the rough body of a gunard, with the same sort of square cross section, but the front half was totally smooth more like a seatrout in shape and feel. The back was dark, the rest of the body and belly was a dull silver. The head was similar to a coalfish shape, but not colour. The eyes were a "normal" size. There was a round mottled black spot on the rear edge of the gill covers, about the same size as you's expect on a similar weight of haddock. The fish was probably about 13" and around 1 1/4 lbs. The water temp was about 4 degrres F lower than normal for the time of year. The fish was caught in about 50 feet of water in an area we usually catch pollock, mackerel and coalfish. The fish was caught on the west coast of the outer hebrides, out of a village called cradhlastadh. When I first hooked the fish I thought it was a mackerel, then I thought it was a pollock. It kinda fought in between the two. When I saw it in the water at first I thought it was a sea trout, and when it was on the boat the confusion began. Hope this all helps, shout if you need more and thanks for the help. If you could let me have the details for the place in Duff I'll send this info to them as well. Dave.

Darryl Mayer Scad, Trachurus trachurus?

Andy Horton Is this is what we call Horse Mackerel (?) this was the furst one that I thought of before I listended to the description.

Darryl Mayer Yes, Andy, often referred to as Horse mackeral, tho not at all related to mackeral.

David Wilson And not very good to eat, very bony.

Andrew Syvret In some parts of Europe they are highly regarded, preferred to "normal" mackerel...

Andy Horton MORE INFO: Hi Andy, the pic of the horse makerel is quite helpful as there are a number of similarities. First to answer your question about the dorsal fin or fins, it had a regular dorsal fin similar to the horse makerel in shape but more spikey like a gunyard and it had a second dorsal fin which was similar in shape to the gunyard but slightly smaller. The pelvic fins were closer in size and shape to the gunard. The overall body shape and colouring was similar to the horse makerel. The lateral line was closer to straight like a gunard with a rough rear half and a smooth front. Hope this helps. Dave.

Ian Macleod Horse mackerel are rubbish to eat, to many bones !!

Andy Horton I do not like bones in my fish flesh. But the worst is Whiting because it is the sharp spines I think. Whiting is good to eat, perhaps best for fish cakes? The bony Gurnard is meant to be good eating as well.
