Compared to the air quality, the water is clean

Murky water, dirty air, and fish that give me the finger We’ve returned to the “fun” part of summer, temperatures breached 103 today, add the smoke burden and it’s about as enjoyable as you can imagine; profuse sweat, extra humidity, and air you can eat with a steak knife.

Perfect opportunity to go fishing, if heatstroke and Mercury doesn’t get us than Cancer surely will. Harsh conditions are always a prelude to the best fishing, and the Little Stinking always welcomes those with diminished IQ and a high threshold for pain.

That new hole in the right boot was welcome, at least for the first 15 seconds, the spreading coolness on my foot quickly became a pants leg full of murk. Carp were in evidence and contentedly mowing grass roots along the bank, which is the way it always starts … them visible, you optimistic, then they crush your spirit by ignoring everything you throw.

I was tempted and there were a couple really big rocks close to hand.

Tight to the bank and facing the wrong direction makes it doubly difficult to see my stuff wiggling in midcurrent, but like most fishermen anything that outwits us consistently is assumed to be smarter than us.

“Aquatic Cows” is more like it, and I scrambled out of the murky water into murkier air and called it a day.

The creek is still only a quarter its normal size and is making the fish spread themselves thinly, what few pockets of deeper water remain hold fish – and everything betwixt that and the next is devoid of life. The combination of heat and poor air has me keeping the adventures short until further notice.

The Red Sun in the evening is pretty – but only from the artificial safety of an air conditioned smokefree living room.

Ignore the Bouquet, it’s all part of the natural order of things

Migration by truck I don’t think the government would be terribly appreciative but we may want to reintroduce the “Viking funeral” for hardcore anglers, what better way to display your devotion than,  “I want to be nutrients for invertebrates.”

A lot of research has been focused at the effect of pacific salmon carcasses in West Coast fisheries, specifically the benefit performed by many thousands of tons of decaying fish distributed throughout the waterway and its banks.

Researchers have traced salmon nutrients to many
different types of organisms, from freshwater invertebrates
and fish to birds and bears and even to streamside
vegetation. These organisms take up the nutrients
by feeding directly on salmon eggs and spawnedout
carcasses, incorporated dissolved nutrients (e.g.,
algae and fungi), or feeding on other organisms that
have taken up salmon nutrients. Streams that are fertilized
by salmon nutrients are hypothesized to be more
productive than streams that receive relatively few or
no salmon.

Salmon apparently have great impact to the insect populations of their host streams, and not all of them are beneficial. Construction of spawning “redds” are destructive to to the host insects – and the density of the spawn can radically diminish insect populations in the prime gravel areas.

After two years of benthic sampling for insect production
and analysis, preliminary results show that the stream bed disturbance caused by salmon spawning activities severely impacts the insect community, reducing density and perhaps even diversity.

This affect is reversed by the decomposition of spawned salmon, and the benefits of carcasses and their debris lasts about 6 months. Researchers are able to see the effects of Carbon, Nitrogen, and Phosphorus, released by the decaying salmon, as their isotopes originated in salt water making them different than resident minerals. Streams vary in mineral richness, and some streams can get a mineral boost in excess of 30% of their historical totals.

Bilby et al. (1996) also monitored growth rates of juvenile
fish, finding that age-0-plus coho salmon exhibited a doubling in growth rate after adults spawned in the stream. In a nearby stream without spawning salmon, age-0-plus steelhead showed no change in growth rate during the winter. High growth rates can increase the overwinter survival rate, and larger smolt size has been related to increased marine survival (Bilton et al. 1982; Ward and Slaney 1988). Piorkowski (1995) qlso found that direct consumption of salmon biomass was the main avenue of nutrient uptake for salmon fry, grayling (Thymallus spp.), and rainbow trout (0. mykiss) in southcentral.Alaskan
streams.

The value of a carcass is obtained only if it isn’t flushed out of the ecosystem due to high water. Streamside debris plays a role in capturing and retaining carcasses long enough for them to be consumed by insects and terrestrial animals.

The bad news is the value to the watershed rises if more bodies are available to decay, as almost all of the Pacific salmon runs are a fraction of their historic size, this makes the host rivers less fertile than before. The implication may be that less returning fish means  the rivers are able to support less insects and juveniles.

The same applies for salmon eggs and released milt. About 30% of the eggs released actually spawn, the other 70% become additional forage for anything able to ingest them.

What isn’t mentioned and might be inferred is the effect of dams on the fertility of a host river. Blocking any migration would remove the beneficial effect of carcasses and suggests the river is immediately less fertile and unable to support historic populations of insects and resident fish.

The short answer is there’s no such thing as a bad way to dispose of fish parts. Tossed onto the bank they’re forage for all manner of terrestrial wildlife and plants, and flung into the creek they’re chow for mayflies, caddis, and everything else, including next season’s fry.

Add it to your list of snappy comebacks should some bird watcher grief you over your “natural” disposal methods – as long as you don’t hit them with it – it’s all good.

Ordering a Pizza might be a better way to get fed

Fishing with a cell phoneSkipping the fishing to go straight to the catching part sounds potentially cheaper, but the virtual odds sound much too realistic to be a cost savings.

I don’t think you’ll want to leave your cell phone lying around; $10 for three casts approximates the cost of fly fishing, but the idea that your kid could pizzle away your entire paycheck, worse yet, could win two or three hundred pounds of fish should cause you to blanch.

The game — called “Ippon Zuri” (which means “pole-and-line fishing”) — was created by FIT, a Fukuoka-based system development company who teamed up with a local seafood wholesaler. Game play is simple: players use the phone keys to cast bait to promising-looking fish in the game’s virtual waters, which include sea bream, crab, and other seasonal fish. When a fish takes the bait, the player is sent to a slot machine screen where, if luck prevails and 3 numbers line up appropriately, the virtual fish is hooked and reeled in. A message is then relayed to the wholesaler, who picks up the real-world equivalent from the local seafood market and delivers it, whole and raw, to the player’s doorstep.

Hardened anglers will balk at the slot machine segment, decrying that fishing could ever compare with any game of chance. I’m not so sure that fading light and tiny naturals isn’t exactly that – chancy at best to pick the correct fly and even less of seeing it to set the hook.

They tried the live action version on those Internet deer hunting sites, I’m guessing the webcam flavor can’t be far behind.

Coiled Stren Indicators

Boiled and Frozen Stren strike indicator Fish and Fly has posted the recipe for the “coiled strike indicator” in their follow-on to “Fishing the Frontier.” Singlebarbed reader, “Z Fisher” was correct in his description of the process; boiled Stren, wrapped around a Cutip, then frozen to make the coils permanent.

Anything that requires fiddling with cooking pots and slopping things onto the kitchen floor has to work in our book – that way the resulting bruises are worth it.

I may have to side with the Fundamentalist’s just once

Genetically engineered piss-water I never thought about the perils of genetically manipulated beef, with my meager BBQ skills I usually eat briquette of “beef like substance”. Charcoal is a spice – get enough black on that haunch and the genetics are the least of your worries.

I’m fine with modified grains – and anything else derived from stem cell research, figuring whatever plague we unleash would be tame compared to what we’d already done to the environment, and it might even weed a few of us conspicuous capitalists off the landscape – lessening the burden somewhat.

But a fellow has to draw the line somewhere’s …

The current flap over a new sewage treatment plant for the Provo River may be our call to arms, not in the traditional sense – but if the manager has his way, they’ll be adding trout to the outflow to test water quality:

Matthews has his own idea for demonstrating the water’s high quality. He wants to build a 10-foot fish tank in the sewer plant to hold a couple of trout from one of the nearby fishing holes. The district will run treated effluent through it.

“If there’s a problem,” he said, “we’ll see it in our own plant.”

The old “canary in a coal mine” ploy – but what if a half dozen fertile fish were to escape after a couple seasons of inhaling pooty water?

It could stimulate catch and release fishing out of self defense, then again, they could be the next Invasive Species – intermingling and inter-breeding with native fish so everything tastes like warm Pampers.

Suddenly I’m waffling on the science front, brown trout are fine – but I don’t want all of them that way…

Homebuilders in Hot Water

The way it's gonna be If you’re one of the big homebuilders the ground has been coming away from underfoot for over a year –  now the courts have determined all that “ground” went into the creek, and in addition to all the homes they have and can’t sell, they’re liable for the sins committed while building all that excess inventory.

It smells kind of like … Justice …

Michigan-based Pulte Homes, Southern California-based KB Homes, Texas-based Centex Homes and Colorado-based Richmond American Homes agreed to pay a combined $4.3 million in penalties to resolve widespread Clean Water Act stormwater violations at hundreds of construction sites nationwide. The companies are also required to implement a program that should prevent an estimated 1.2 billion pounds of sediment from entering the nation’s waters each year.

In Northern California, the beneficiary will be the Garcia River, home to a modest run of both salmon and steelhead.

Pulte will spend an estimated $418,000 on the North Fork of the Garcia River, the largest sub-watershed of the river, to treat an estimated 13,475 cubic yards of stored and road-related sediment, and upgrade all permanent and seasonal roads and stream crossings within the sub-watershed. The North Fork project will decrease sediment loading and runoff and improve anadromous fish habitat.

The company will also spend an estimated $190,000 on the Blue Waterhole Creek, which is a high-priority for restoration because although it contains good natural pool structures desired by anadromous fish, it is also subject to very high water temperatures lethal to young coho salmon.

Now that we’re counting Salmon on one hand every little bit helps, whether this is the start of an endless chain of appeals, or the start of something tangible remains to be seen.
