Fishing

Overview

Rainbow Trout - Oncorhynchus mykiss

Also known as: Kamloops, Rainbow, Redband Trout, Silver Trout

It is native to the west coast of North America from southern Alaska to Durango, Mexico and inland as far as central Alberta in Canada and Idaho and Nevada in the U.S. It has been extensively introduced across the lower Canadian provinces and throughout the area of the Great Lakes to the Atlantic coast, south in the Appalachians to northern Georgia and Alabama, east in the southern U.S. to western Texas and sporadically in the central U.S. as well as above the Great Lakes on the Atlantic coast. It has been transplanted to New Zealand, Australia, South America, Africa, Japan, southern Asia, Europe and Hawaii. An Asian species known as the Kamchatka trout is believed to be a form of the rainbow trout. It is native to the Amur River in the eastern part of Russia as well as Kamchatka and the Commander Islands.

Coloration varies greatly with size, habitat and spawning periods. For example, stream dwellers and spawners usually show the darkest and most vivid colors and markings, while the steelhead is silvery when it returns from the sea. Though noted for the broad red or pink stripe along the middle of its sides, this stripe may not be present on all forms, particularly the sea-run steelhead and immature specimens in clear lakes. A similar stripe is sometimes present on the golden trout (Oncorhynchus aguabonita) and the cutthroat trout (O. clarki), though the golden trout usually has about 10 prominent parr marks on the sides through adulthood (uncommon but not unheard of in adult rainbows). The cutthroat can usually be distinguished by the yellow, orange, or red streak in the skin fold on each side under the lower jaw. In some waters rainbow trout may faintly display this streak in the skin fold, but most do not.

The rainbow and its closest relatives in the Pacific salmon group (cutthroat, golden, Mexican golden, Arizona native or Apache, and gila trout) are known as the black-spotted trouts because they are covered with numerous prominent black spots. These spots may cover the entire body or may be more abundant near the tail. The spots characteristically extend onto the dorsal fin, the adipose fin, and the tail. Those on the tail radiate outward in an even, orderly pattern. Spots may or may not be present on any of the lower fins and there are never any red spots such as occur on freshwater and spawning specimens of brown trout (Salmo trutta) and Atlantic salmon (S. salar). The rainbow trout readily hybridizes with other black-spotted trout, especially with the cutthroat and golden trout. In fact, all these trout hybridize wherever they occur together producing fertile offspring with all manner of confusing color combinations and intermediate characteristics.

This is an extremely valuable species in any and all of its forms. It is the fly fishermen’s delight as it takes a fly readily, leaps often, and fights hard. Though there is no direct commercial demand for the rainbow it is taken by Pacific salmon fishermen and it is pond-reared in Europe and Japan to be sold as frozen whole fish. The flesh ranges from bright red in small lake and stream populations to pink or white in large lake, stream, and steelhead populations in which the diet is primarily piscivorous. It is excellent regardless of color and my be cooked in any manner desired.

Habitats

Overhanging Trees and Bushes

Usually close to shore, these spots offer protection from the sun and above-water predators. Bigger fish rest in these areas if the water isn’t too shallow, allowing quick access to deeper water for feeding and escape.

Outsides of Bends

When the river or stream curves, the faster water (which carries the food) moves to the outside of the bend, and fish look for food in these bends. If the outside of the bend also contains a rock or fallen tree (to slow down the food-carrying current), it’s an even better place to catch fish.

Current Edges

A current edge is a place where natural or man-made objects slow the current. When the current slows, the food that travels with it also slows. So fish rest at current edges and wait for a nice, slow meal to come by. Current edges can be created by natural or man-made structures like bends, merging currents, drop-offs, rocks and islands.

Merging Currents - Feeder Brooks, Stream or Creek Mouths

Flowing water carries food. So when two bodies of flowing water meet, fish will find twice as much food. Plus, when currents collide, there’s a small area in the intersection where the water and food actually slow down, making merging currents an excellent place to catch fish.

Drop-Offs

When water flows over a drop-off, it slows down and sinks, taking the food it carries with it. A drop-off is a great feeding place because it has food, deeper water and it’s away from the current, allowing for a more relaxing dining experience for the fish.

Rock and Boulder Pockets

When flowing water hits rocks and boulders, it splits and goes around the obstruction, creating an area of calm water on the downstream side of the obstruction. Fish will rest, facing upstream, on the downstream side of a rock. These pockets are small, but a handy cast could land you a fish.

Undercuts

Undercuts are considered the perfect hiding spot on the river. They occur where the current has cut out a cave-like hole in earth or rock along the shore. If there’s a tree above the undercut, all the better. Undercuts provide protection from above-water predators and the sun. And easy access to deeper water for feeding or escape. The biggest, baddest river fish live in undercuts.

Dams and Falls

When water continually drops off a dam or falls, it creates a big hole or drop-off. Fish will sit at the bottom of these holes to get away from the current and to eat sinking food. Fish can get trapped in these holes if they are going upstream to find cooler water or to spawn.

Small Pointed Waves

These triangle-shaped waves form where faster water meets slower water. Like the riverside edge of a bend, bay or eddy. Large fish gather under these waves because the water slows and food drops.

Riparian Zones

Riparian zones are the middle strip of vegetation between the river and the flatter land beyond the shore. These zones serve as a natural biofilter to protect water from excessive sedimentation, polluted surface runoff and erosion. And they supply shelter, food and shade for fish and other aquatic animals. A thriving riparian zone is a sign of good water quality and good fishing.

Rivers and Streams

In a lake or pond, fish have to move around to find food. In a river or a stream, the food comes to them. So moving-water fish find hiding places and travel anywhere from a few feet to up to several hundred feet, several times a day to eat.

You have to decide if you’re going to fish where the fish are hiding or where the fish are feeding. Either way, you’ll have to learn about river and stream feeding and hiding structure.

Hiding structure include undercuts in the banks, eddies, sunken trees and overhanging trees and bushes: places that provide protection from the current and above-water predators.

Feeding places include the outside of bends, merging currents, drop-offs, feeder brooks and springs: places where the current slows down and food collects or sinks.

In general, fish found in moving water tend to be a little smaller than lake fish. But they’re fighters, strong from battling the currents.

Eddies

When fast moving water flows into a small inlet, or eddy, it slows down and creates a whirlpool. Fish will feed where the whirlpool is slowest or in the main body of the river where the whirlpool kicks out the food that has been carried in and out of the eddy.

Standing Waves

If you see waves on the water that look like a rollercoaster, the water is probably going over underwater rocks. Fish like to sit in the shallow part of these waves.

Fishing Methods

Bait Casting

Bait casting is a style of fishing that relies on the weight of the lure to extend the line into the target area. Bait casting involves a revolving-spool reel (or “free spool”) mounted on the topside of the rod. Bait casting is definitely an acquired skill. Once you get the hang of the technique (check out the casting animation), you will be casting your lures right on target into the structures where fish are feeding and hanging out.

With bait casting, you can use larger lures (1/2 to 3/4 ) and cast them for longer distances. To get started, you’ll need a rod with good spring action, a good quality anti-backlash reel, 10–15 pound test line and a variety of specific bait-casting lures.

Fly Fishing

With fly-fishing, various materials are used to design a very lightweight lure called a fly. A fly can serve as a ‘dry fly’ or ‘wet fly’. A dry fly will float on the water and mimic a floating insect and a wet fly will sink below the surface to mimic a swimming bait. It takes a little practice, but fly-fishing is a pure and exciting way to fish. Unlike other casting methods, fly-fishing can be thought of as a method of casting line rather than lure. Non-fly-fishing methods rely on a lure's weight to pull line from the reel during the forward motion of a cast. By design, a fly is too light to be cast on its own so it must follow the trajectory of the cast fly line, which is thicker and heavier so that it casts easier than lines used in other types of fishing (such as monofilament). The angler normally holds the fly rod in the dominant hand and manipulates the line with the other hand close to the reel, pulling line out in small increments as the energy in the line, generated from backward and forward motions, increases.

Bait & Lures

Cured Fish Roe

Salmon or trout eggs are one of the most effective baits when targeting fish like salmon, steelhead and trout. When spawning fish are active in the streams, rivers, shorelines or harbors they will often ignore any other baits and lures that you try to throw at them. An egg spawn sack (usually a small pouch of cheesecloth with clusters of eggs) or cured skein (cluster of cured eggs) can be attached to your hook and can either be left to float freely or weighted with a small sinker to get the bait deeper. Cured fish roe can be found at most bait and tackle shops or with a little bit more effort, you can make it yourself.

Flies

Poppers and flies are small lures used with spincast and fly-fishing tackle. These baits are very good for pan fish and other fish that feed on the surface such as trout and bass. Poppers get their action from a cupped face carved or molded into the front of the lure body. Fly action is totally controlled by the angler.

Insects

Ants, beetles, grasshoppers, crickets and caterpillars are ideal for catching pan fish, sunfish and trout. Brown trout are especially attracted to ants presented on a fly. Smallmouths and large trout prefer immature versions of mayflies, stoneflies, caddis, hellgrammites and dobsonfly larvae. You can buy insects or catch your own. Ants can be gathered from a nest and large insects can be captured with a net.

Jigs

Jigs have weighted metal heads and a tail made of animal hair, soft plastic, feathers or rubber. Anglers sometimes add a minnow or piece of pork rind to the jig's hook. Jigs can be used to catch nearly every kind of freshwater fish
