The brown trout is an economically important species, particularly due to its popularity with anglers, and stocks are maintained in many areas by artificial introductions.
This fish feeds on invertebrates, insect larvae, aerial insects, and molluscs, as well as the occasional fish and frog Spawning occurs between January and March, when females are accompanied by a number of males. The eggs, which are fertilised externally, are covered with gravel by the female. For the first days after hatching, the young fish (fry) derive their nutrients from their large yolk sacs; they then feed on small arthropods, such as insect larvae. The maximum-recorded life span of a brown trout is 5 years. Brown trout are voracious eaters therefore the Owyhee River with it’s 25,000 bugs per meter is a prime brown trout fishery.
Oncorhynchus is Greek meaning “hook snout”, and mykiss is the Kamchatkan name for rainbow trout. Rainbow trout have a characteristic salmon-like shape. Dark spots are clearly visible on the tail fin, which is slightly forked. The anal fin has 10-12 rays. The back is usually a dark olive color, shading to silvery white on the underside. The body is heavily speckled, and there is a pink to red stripe running lengthwise along the fish’s sides.Life HistoryRainbow trout is an anadromous, cool- to cold-water fish species.
Although rainbows have been known to tolerate higher temperatures, they do best in areas where the water remains below 70°F. Eggs are laid in shallow nests dug out by the female in gravel riffles. The eggs require continuous oxygenation. At temperatures of about 55°F, the eggs will hatch approximately 21 days after they are laid. Rainbow trout are carnivores, but not exclusively piscivorous. They feed on a wide variety of prey including insects, crustaceans, mollusks and fish. Rainbows with access to the sea have been known to exceed 42 pounds. The record size for those confined to freshwater is 31.27 pounds.
Rainbow trout are native to North America west of the Rockies from Alaska into northwestern Mexico. Introductions have extended the range to include the Great Lakes region, south central Canada and portions of the Great Plains east of the Rockies, and southwestern Mexico.
• Invasive species and infectious diseases are becoming more prevalent and widespread with increased connectedness and globalization
• Alien species are the second leading cause of extinction in the US and cost approximately $120 billion annually. Disease vectors and pathogens are spreading
across continents due to human transport,
land-use change, and climate change• To adequately understand and predict the spread of invasive species and disease, we must coordinate
the many existing networks at local, regional, continental, and global scales
• Both observational and experimental approaches are required to fully understand the effects and impacts
of invasive species and diseases and, more importantly,
to understand the biotic and abiotic factors that enhance or diminish their effects
What are they & what do they look like?
Didymosphenia geminata, also known as ‘rock snot’ or ‘didymo’, can smother entire stream beds with mats as thick as eight inches and can ruin just about any river or creek.
New Zealand Mud Snail
The rapid spread of the mudsnail throughout the Yellowstone watershed may have been assisted by human transport. Anglers – Early research indicates that this group will probably be most impacted by the New Zealand Mudnail. If this species does have long term impact, wester trout fisheries could become devastated.
Why Should I Care?
Everyone should care because zebra mussels are known to have caused alarming declines in populations of fish, birds and native mussel species and can disrupt a city’s entire water supply system by colonizing the insides of pipelines and restricting the flow of water.
What can you do?
CHECK — Before you leave a river, stream, or lake, check items and leave debris at site. If you find any later, treat and put in trash. Do not wash down drains.
CLEAN Non-absorbent items
- Detergent — soak or spray all surfaces for at least one minute in 5% dishwashing detergent or (2 cups (16 oz.) or 500mls with water added to make 2.5 gal. or 10 litres); OR
- Hot water — soak for at least one minute in very hot water kept above 140° F (60° C) (hotter than most tap water) or for at least 20 minutes in hot water kept above 113° F (45° C) (uncomfortable to touch).
Absorbent items — require longer soaking times to allow thorough saturation. For example, felt-soled waders require:
- Hot water — soak for at least 40 minutes in hot water kept above 113° F (45° C) ; OR
- Hot water plus detergent — soak for 30 minutes in hot water kept above 113° F (45° C) containing 5% dishwashing detergent; OR
- Freezing any item until solid will also kill most all invasive species.
DRY — Drying will kill most invasive species, but slightly moist didymo can survive for months. To ensure invasive species cells are dead by drying, the item must be completely dry to the touch, inside and out, then left dry for at least another 48 hours before use. If cleaning or drying is not practical, restrict equipment to a single waterway.
NOTE: The thicker and denser the material, the better it will be at holding moisture (and live cells), the slower it will be to dry out and the more difficult it will be to soak completely with cleaning solutions.
- Inspect every inch of your boat, trailer, and equipment – the hull, drive unit, trim plates, props, anchor, centerboards, paddles, wheels, hitch, chassis, etc. – and remove aquatic plants, animals, and mud from the boat, trailer and equipment before leaving any body of water;
- Drain any and all water from your boat and equipment on land before leaving the area;
- Do the following when away from direct drainage areas to lakes or rivers:
— Dump any leftover bait on land, especially if the live aquatic bait has been in contact with potentially infested waters;
— Disinfect live wells and bait wells, bilges, cooling systems, hulls, and decks with a 1:9 solution of household bleach and water allowing at least 10 minutes contact time. Rinse well to remove all residual chlorine. An easy recipe is a half gallon of bleach into a 5 gallon bucket then fill with water (or a quart of bleach to a half bucket).
- Rinse your boat after use, preferably with hot water. If hot water is not available use tap water and then allow at least five days to become completely dry before entering a new water body.
- Do not transport any LIVE FISH, BAIT, OTHER CRITTERS, PLANTS, OR WATER from one body of water to another.

Due to our own environmental and social concerns, we do not guide on the Owyhee during the spawning period of October and November. Join us on the Grande Ronde for some fabulous dry fly steelhead fishing!

Andrew Catt guided myself, my son, and my father-in-lawn on the Owyhee River in Late May. What a great experience! I had never fly fished before, but Andrew was very patient and informative. His patience with my 9 year old son was outstanding! Andrew had to run around constantly helping us to get on the fish, teach us, tie lines, etc. and he never missed a beat. We were fortunate enough to add some nice sized brown trout to the experience and the beautiful scenery of the Owyhee Mountains. It was a trip I we will never forget, and it is all mainly due to Mr. Andrew Catt and Dreams on the Fly.
Andrew was great with my 10 y/o son. Very patient and positive. Would highly recommend.
