I am reading that one of the boat of Didier Jeanne claims a striped marlin capture in Mindelo waters during past days
Looking at the picture Didier showed at his website...could be a small blue instead???
Would be the first time I hear about stripey caught up north in atlantic ocean.
What do you think??

Well David there is an old Anglo Saxon truism, ‘Never say Never’.
And I can remember my initial shock/disbelief when on hooking what I thought would be a Roosterfish off Isla Coiba, Panama – in the Pacific – a Tarpon, Megalops atlanticus, jumped. But since then any number of our Club members have hooked them in the Pacific resulting on one finally landing one (image attached) in Pinas Bay, Panama (Tropic Star Lodge) last August. In the case of Tarpon though, especially immature fish, they are quite capable of living in waters with low salinity or even freshwater. So the supposition is that the original population made the transition – Caribbean to Pacific – through the Panama Canal.
And, on that same trip, we landed a small Tuna which the crew just viewed as ‘bait’, a Bonito. When pressed, they suggested it was an odd coloured Black Skipjack. But, on closer examination, it had small conical teeth, and we subsequently identified it as a Kawakawa, literally thousands of miles away from their normal distribution range in the west and central Pacific.
But Marlin? Um ….
So, Blues and ‘Stripies’ are superficially remarkably similar other than, in relative terms, a higher dorsal fin that – in the case of a Striped Marlin - equals or sometimes exceeds the fish’s body depth. Didier though has seen lots of Blue Marlin and this patently was something different, to his mind something unusual.
Was it smaller than the normal run of fish? That may, assuming it was a juvenile Blue, have accounted for the proportions of the dorsal being bigger than normal. I recall once whilst fishing Venezuela in a Club tournament one of our members releasing a 70lb billfish. What was it? Well patently not a White, that’s fairly easy to identify. It was a very small Blue, much smaller than the normal run of fish they encounter.
Or could Didier’s fish have been a hybrid, a cross between a Blue and a White? I’m really uncertain of what research, if any, has been conducted. Or was it a Hatchet Marlin? Some research has indicated that this, for long described as a ‘White Marlin variant’, is a separate species. The fin tips – the dorsal and pectorals – are apparently less rounded.
Which I suppose brings us back to Didier’s original assertion, it was a Striped Marlin. So where are the closest populations? The Indian Ocean coast of South Africa and, of course, the Pacific coast of Central America. To my mind everything suggests that the waters would have been too cold for fish to have travelled around the Cape of Good Hope, from Indian to Atlantic. But I do recall seeing a rather ancient picture of what appeared to be a Black Marlin caught off St Helena in the South Atlantic. Um … The other even more remote possibility of lava (?) or fry making the transition through the Panama Canal would require them to survive in freshwater.
So that’s all a long way of saying I really don’t know. Do you have any other information though? And could you please post the url of Didier’s web site? It would be interesting to see a picture of the fish.

PS Must, at some point, respond to yours and Bernos comments about hook up ratios. Perhaps tomorrow?
