Very interesting that mate, in particular the growth rates and recapture rates: They reach 8.8lbs by the age of 2! 20lbs by the age of 6! amazing. Other interesting sections pulled from the research: Stomach contents of some adult sea trout were analyzed, in order to confirm the assumption that adult sea trout are not feeding in the river. Indeed, the majority of fish analyzed had empty stomachs and several dead fish that we gutted had no evidence of any recent feeding. However, approximately 25% of adult fish that were stomach pumped regurgitated a small amount (relative to resident adults and juveniles). Food items consisted mainly of scuds (87.5%), and, in one case, a mostly digested unidentifiable fish. Those fish with a small amount of food in their stomachs appear to be first time spawners based on the scale analysis. During the course of the season, guides and others tagged a total of 1043 (19.9%) fish out of the 5233 fish caught between the five participating lodges. Of the 1043 marked fish, only twenty (0.02% of tagged fish) were recaptured, or recorded as recaptured, during the season. TT.

TT
Is there a trypo there? or I am misreading the graph in some way (not accounting for time in river or something).
Looks like 4kg/8.8 lbs at age 6 -- 20lbs - 8Kg aged about 13.
Anybody know how these growth rates compare to UK fish?
cheers Nf

Here's a link that may be of interest to give some relation to ours: eis.bris.ac.uk/~cckhrb/physiology/lc_sewin.htm2+ years being 25cm, being our school fish I guess, 8oz - 3lbs. TT.

Hi TT
thanks for that - thought I might be missing something as I said - and the link to the UK fish was interesting.

Steff; The 85.5% did not really surprise me as this food item is what is primarily found in most of the trout that are caught over this side o' 'da pond.My initial post to this forum at day one asked if any of this forum's members ever used a bait known as a "laterally compressed amphipod"or to spekus latin Gammerus oceanicus It is what I believe to be the main staple in sea trout diet owing to their abundance in the water, which is why it is the #1 bait of choice for those sea trooters& "stickers" over here on 'da Avalon "D'ey do "catchus fishicus" ;D ;D Still stickin'...Andrew

That's really interesting Andrew, both cases seem to be very different from ours, or so I believe. I can't say that I have ever found anything in the stomachs of the sea-trout I have caught in the UK, and certainly not to the extent of that statistic. I'm sure that the odd one gets caught over here with a measure of food inside, but not frequently? Does anyone on the forum have any views to the contrary? anyone found large amounts of food left in their system? Oddest thing found left in their system? TT.

Interesting that this correlates with what we know of smaller school fish in terms of "more likely to feed occasionally" than their larger brethren...
Whether this is because they have more recent "river memory" or, in other words, haven't been at sea as long I can only guess.

Not me personally,I don't kill many,and the very few I do keep are for friends and family,these are usually given with the guts still intact.The few I have gutted have never had anything in them. A few mates who tend to keep more for the table than they release have found food items in the stomach on more than a few occasions.One 8lb fish I can remember had a couple of smolts/small brownies ? in it's gut of around 6"inches in length. Another fish which was rising steadily to spinners,and a fish in which the person who caught it thought was a brown.Covered it with a small spinner pattern,the fish took it,and turned out to be a seatrout of around 5lb fresh as they come.When gutted,it was absolutely stuffed to the brim with spinners.

Blymin eck, they did well! I can usually only get them to rise once for the spinner then that's your chance gone. And to think that it had a load of mepps and rapalas in its gut too, poor fish! I'm not surprised that it was gutted, it certainly couldn't have been happy! TT. ;D

Daz,
Do you think they'd rise for FlyingC's - stumpy does floating versions and im thinking if Sewin rise to spinners on the Neath, perhaps they'd come to a suspended black and silver flying c?
Hoppy ;D ;D

perhaps they'd come to a suspended black and silver flying c? Cracking idea that! Perhaps under a fish-pimp, or a klinhammer? Then you'd get the sewin that are feeding on the surface spinners and the heavy, diving spinner! TT. ;D

I knew it was a bad idea to post what I did when I read it back. ........B#stards!. ;D You pair seem to know alot about spinners etc! ....Fly only me. Typical response from you non purists. wonder why they call it "Nervous waters" Has Daz been down that way with hiz L'il box o' triks ;D ;D ;D Still stickin'...Andrew It's called "nervous water" Andrew because of the worry of one of them metal chucking ####### hitting you on the back of the head with a 20grm lure.

I usually make the bodies for the floating flying c's from balsa,but tried one using expanding foam,i used a latex body and filled it with foam,once the foam had set i cut the excess from the back end,i was a bit worried about the hook puliing through the foam so i added a couple of sequinns just above the treble to stop every thing pulling through the foam(seems to have done the trick)used a smaller blade(size 3)and 0.6 wire instead of 0.8,and size 8 treble,all to reduce weight,and it seems alot lighter than a balsa bodied flyin c.... stumpy.....
