TR: Bull Trout Presentation
 

I'm taking off in the morning for the Hoh, so this will be short, but
hit on the main points of last night's presentation in Port Angeles.
I'm including the things I remember from the talk, and I'm omitting
anything I'm not sure was straight from Sam or Steve. Come to think of
it, I'm omitting lots of things I don't remember off hand as well.

Sam Brenkman is the National Park biologist in charge of the bull trout
telemetry study. He and Steve Corbet gave a presentation to about 30
or 40 people last night at the visitor center in Port Angeles to
describe the intermediate results of his study. The study is
commissioned for 4 years, so he's just past half way through it.

For 2 and a half years he's been inserting coded radio tags in Hoh
river Bull Trout. 72 fish were captured in the Hoh, mostly by hook and
line, and 9 were captured in Kalalock Creek. They also acquired 107
frozen fish that were unintentionally netted by the local tribes at the
mouth of the Hoh. The frozen fish were disected and analyzed for
various genetic data, and stomach contents. Almost all the food they
could identify was surf smelt, the remaining 8% was sculpins. All
these fish were netted near the salt, so this reflects the food they
find in the estuary.

All the fish wandered out to the ocean, and most of them were later
found at the mouths of the rivers south of the Hoh, down to the
Quinalt. 25 fish went into the ocean after spawning and disapeared.
One of those came back last week after 15 or 16 months of absence.
They're hoping more of the 25 will return from their wandering. No
tagged fish have been detected north of the Hoh.

Sam said this was the first study to prove that Bull Trout can be
anadromous. There is lots of evidence for migration into and out of
reservoirs (I've forgotten the word like anadromous for this behaviour)
in inland areas, but this is the first study to find them in the ocean.

The west coast river fish are all bull trout, no dolly varden. There
are landlocked populations of dolly varden in the upper Queets, upper
Sol Duc, both populations are above structure that blocks upstream
migration. This was interesting because it's exactly backwards of the
expected distribution. Prior to this study, Bulls were considered an
interior fish, and Dollies were their anadromous cousin.

Despite the similar appearance of bulls and dollies, they are no more
similar than cutthroat and rainbow trout.

Bulls will cross breed with brook trout, but the offspring are sterile.
Sam didn't provide details about the results of bulls and dollies
cross breeding.

Potadromous?

Thanks for the info Chas.

diadromous = live in ocean, spawn in fresh (anadromous) *or* live in
fresh water, spawn in ocean (catadromous)...doesn't seem to fit.

amphidromous = moving from normal fresh or salt to the other water to
eat or survive drought but not to procreate. perhaps?

??

ditto on info thanks...

Great Stuff Chas.

If any of you get the chance to fish with Chas you'll find out that he's
even friendlier and more enthusiastic in person. I know that it doesn't
seem possible but it's true.

actually... some of us fished with chas and his wife on a fine grayling
lake in montana. chas and his wife had the good sense not to carry a
boat up the mountain and to fish from the banks, catching as many
grayling as those of us with blue balls kicking about in the
water...(guess which idiot wore shorts in a float tube). chas' wife was
most enthusiastic while catching those grayling jewels... lots of fun
and good company ....

Chas that's damn good info. I've really enjoyed following your bull
trout threads.

Potadromous works, but Adfluvial is what I was looking for. I think
they're synonyms.

Thanks

That's a new word for me, it sounds about right, I'd need to understand
when it's used, but I think that it probably applies more to cutthroat
and Dolly Varden with their sneaking in and out of the estuaries. Bull
trout use reservoirs like salmon use the ocean, they move out at a
tender age, and come back for sex. The Bulls in the Hoh seem to
include both amphidromous and anadromous fish.

Thanks guys, it was great fishing with you in Montana and New Mexico.
The guys who don't go to claves are really missing the best part of
ROFF.

A couple things to add, that I just remembered. They have been looking
for the Bull Trout in the tributary streams, but haven't found any of
them up there. They seem to stay in the main river, or go out to sea.

I went back to the Hoh today, on my son Andy's advice. He was out
there yesterday and caught 5 steelhead. The biggest was 35 inches and
"so fat it wallowed away when released". I couldn't find his hot spot
today, but I did catch a 10 pounder and a 5 pounder, and a 20 inch Bull
Trout (still none with the radio tag in it). It was a 4 hour drive
over there, 8 hours of fishing, and a 4 hour drive home. Well worth
the trip.

Thanks Willi, it's been a lot of fun learning about these fish. Quite
a surprise to learn that what we were calling Dollies are actually Bull
Trout. It was also great to watch Sam and Steve give the presentation.
Their enthusiasm for their work is contagous.

mcphee used these words in his shad book...he was hanging around with
fish scientists, so i assume they are correct terms. i'd only read
about anadromous fish before mcphee's book. he offers a lot of
interesting fish science for the casual reader. but...i was surprised
none of his recipes included deep-frying. i doubt many in eastern nc
would eat baked or broiled shad - properly breaded and deep-fried (after
scoring the filet) is the best method of cooking the bony alosa
sapidissima... and, i'd recommend doing it outside, unless your family
really, really likes a fish scented home.

I really like shad roe, and I buy it and cook it whenever I can find it,
which isn't often. When I was growing up in Baltimore it was plentiful
and cheap.

I fry it in bacon grease. If you try it, make sure you put a wire screen
over the frying pan, or you'll make one helluva mess. Those eggs explode
like little grease bombs. This probably isn't the best dish for someone
with cholesterol problems. :-)
