It was pretty, still and cooperative. Not sure what it was name wise. Vibrant and crisp in the Fall air. Lepidopterology (General or Very Specific)

Natural Barriers: Dougan Falls and Wild Steelhead Purity

Well, almost pure strains of wild steelhead make their way above Dougan Falls on the Washougal River. Natural barriers, in this case a waterfall, seem to act as good obstacles to separate out the inferior hatchery steelhead from the wild steelhead. 

Studies have been conducted over the years to chart the passages of hatchery and of wild steelhead in various watersheds. The Washougal River has no man made barriers, only natural barriers in waterfalls.

“On the Washougal, our data indicate that natural passage barriers (waterfalls) effectively isolate returning wild steelhead from straying, hatchery-origin adults. Above Dougan Falls on the Washougal, less than 3% of returning adults have been identified as hatchery origin. Using this data, WDFW determined this area to be a genetic sanctuary…” (Clark-Skamania FF)

Bigfoot Study & DNA (Alleged Human Factor)

“A scientist in Texas is claiming to have sequenced the genome of Bigfoot, alias Sasquatch or Yeti. Researcher Melba Ketchum led a team of scientists in a five-year DNA study purporting to confirm the existence of the hominin hybrid species commonly referred to as Bigfoot. The findings of this study are not yet published and are currently undergoing peer review.” (x)

A Fish in Hand is Worth Two in the Book

 

FISH BIOLOGY..Dry stuff

Personally, beyond identifying various fish species, I don’t care about the why’s of color beyond adaptation and camo. I simply marvel at their individual beauty. Good enough for me. My mind, anymore, glazes over with too much detail re fish, entomology, climate change, etc. I simply want the decompression and want to think less and less. For now anyway.

Every Day in May Writer’s Challenge: ‘Bugs’

EVERY DAY IN MAY CHALLENGE TOPICS DAY BY DAY

BUGS? Once again, my short comings are brought forth in print. Entomology, Latin, Genus, Species, Orders and Families. I have enough trouble remembering everyone in my own family let alone memorizing fancy names. Colors, size, hatch time, hatch location and a little studying in advance is often as best as I can do. The common names: Mayfly (BWO, PMD, Callibaetis, Green Drakes)…Stoneflies (Goldens, Little Blacks, California Stones, Skwala)…Caddis (Long Horns, Traveling Sedge, Cinnamons) Midges/Chironomids…Dragon and Damsels…  

Nothing too fancy there. I turn a rock over in a stream and see dark mayfly nymphs scurrying for their lives. I saw the size and color but wouldn’t be able to tell you which mayfly it is. I can maybe tell it was a clinger/crawler or swimmer etc. The other morning, I started to put on my waders. Overnight, a Caddis hatch had taken place as my waders and the nearby railing had large adult Caddis sitting there. Over a half inch long and medium brown in color. Hmm? What Caddis is that? Would I fish it now, or did it hatch last night? At least I noticed the body of water definitely has large Caddis. Maybe that is what I saw skittering across the surface early one morning? 

Believe me I have tried. I study, I read and look at pictures, I study TroutNut and I certainly tie all Winter to match insects. Take away the hatch charts, books, blogs, outside advice, then I’m left  observing and trying this and that…it is the essence of observation and adapting and then, maybe, bringing to the table whatever else you learn from outside sources.

This beauty was clinging to the side of my car last year. I have a little spring in the back yard. I have seen the rare Caddis and then this large Mayfly. You’d think I would followup with some foraging in the spring to see what really lives out there. I haven’t….yet.

I do take satisfaction in turning over those rocks, looking into stream side vegetation, watching little sailboats float down the river or inspecting the Caddis fluttering on the inside of my sunglass lens. I look at the coloring of Stoneflies crawling ashore and sat in amazement as Waterboatman (Corixia…look at that!) dive bombed a lake one October afternoon. There you have it. I have bombed out at Bug Basics 200. I do believe that the more I can fish, I will add to my knowledge. Heck, I probably know more than I realize. Just don’t ask me any Latin Names…although I do like that Hexagenia Limbata name….sounds like some Cuban Dance or Caribbean VooDoo thing in New Orleans.
