How to catch a 10 kilo sea trout on fly - Things you need to know. Fly fishing in the Mörrum river

Important things you need to know to increase your chances of catching a monster sea trout

From late June, the sea trout begin to migrate up the Mörrum river to spawn - and it can be big fish. There’s a reason why fly fishermen come from all over the world in hope to catch one of these large, shy specimen.

The best chance of catching one of these monsters is to fish in the evening but if the weather is cloudy or rainy there is also a fair chance during the day. "Rainy weather is sea trout weather" as we say in Sweden.

During autumn fishing in the Mörrum river, the ultimate catch is a sea trout over 10 kg taken on the southern stretch, which is the stretch closest to the Baltic Sea. If you catch a fish here, you know it's in top condition because it hasn't been in the river for long.

I have been fishing the river for over 35 years now and certainly have experienced many unforgettable moments. Both in terms of fish I caught as well as fish I lost. However, this fish was exceptional and I will absolutely remember this catch for as long as I live.

It really was a rare occasion. A monster sea trout - and a witness! Usually I land the fish myself but this time I had the help of my eldest son Martin, himself a very skilled fly fisherman.

It was truly amazing to be able to share this incredible catch with him.

In Swedish:

Från slutet av juni börjar havsöringen vandra upp i Mörrumsån för att leka – och det kan vara stora fiskar. Det finns en anledning till varför flugfiskare kommer från hela världen i hopp om att fånga ett av dessa stora, skygga exemplar.

Den bästa chansen att fånga ett av dessa monster är att fiska på kvällen, men om vädret är molnigt eller regnigt finns det också en rimlig chans under dagen. "Regnväder är havsöringsväder" som vi säger i Sverige.

Under höstfisket i Mörrumsån är den ultimata fångsten en havsöring över 10 kg tagen på den södra sträckan som är sträckan närmast Östersjön. Om du fångar en fisk här vet du att den är i toppskick eftersom den inte har stått länge i ån.

Jag har fiskat i Mörrumsån i över 35 år nu och har verkligen upplevt många oförglömliga stunder. Både vad gäller fisk jag fångat och fisk jag tappat. Denna fisk var dock exceptionell och jag kommer säkerligen att minnas denna fångst så länge jag lever.

Det var verkligen ett sällsynt tillfälle. En monsterhavsöring – och ett vittne! Vanligtvis landar jag fisken själv men den här gången hade jag hjälp av min äldsta son Martin, själv en mycket skicklig flugfiskare.

Det var verkligen häftigt att få dela denna otroliga fångst med honom.

What a fish and you are totally right about fluorocarbon it’s useless

[alessioferretti]

Great video and amazing fish!! 😱 I would have one question, where do you think it might be a good spot for mid May salmon fishing, I've heard that usually they go to the up part of the river from June

Hello John,
What is the best period to catch sea trout at the Mörrum?
Any other tips for catching sea trout over there?
Nive vids.
Greetings and tight lines from The Netherlands.

What a fantastic fish and well done on landing it in that fast current. My son ( from the UK ) now lives in Sweden and next time I visit I’d love to take him fishing on The Mörrum . Do you have any contact details for the beats so that I could arrange some fishing on the river ? Best Wishes and tight lines Danny 🎣

Thanks for the video, very nice. I'm fishing the Mörrumsån next month and it will be first time fishing there. Hoping to catch sea trout or salmon in autumn, or otherwise just enjoy the river. For the lines, would you just use a floating spey line and directly attach the 0.40 tippet (it's without any taper, right?). Or is the line set-up more complicated than that? Also, I was thinking of bringing a net to land potential fish. Is that a good idea?

Congratulations. Why exactely do you think flurocarbon sucks?

You cant teach people to catch a 10 kilo seatrout, the person need to fish where 10 kilo sea trout exist and need a bit of luck to make one take the fly. That's it.
