How Bass Locate Prey
Bass are superbly designed to attack and kill at close range. Their hydrodynamic design and fin arrangement allows them to maneuver silently. They usually stalk their prey and ambush from short range. When a bass makes the final rush it rarely misses
it changes its mind at the last
instant. Refusals can be as dramatic as takes.
Most experts agree that sight plays the major role in bass food acquisition. Bass have remarkably well adapted eyes for the environments they inhabit. They see shapes, colors, movement and distance very well at mid and close range. Eye arrangement in the skull allows for binocular and wide peripheral vision. This enables bass to locate and study their prey and assess how to best attack it. Sometimes a bass will study prey and stalk it for a matter of minutes before attacking. However this stalking process can start long before prey could possibly be in visual contact. Often you will see a bass start to edge toward your fly while it is still obscured from direct view by weeds or other obstructions.
This is because bass also have a very acute sense of hearing. Sound travels more efficiently through water than through air. Bass use this efficient sound transfer to locate prey in weeds, turbid waters or low light conditions. They hear normal frequency sounds with an inner ear very much like our own. They detect low frequency sounds with special nerves located along the lateral line. It is believed that bass may very well be able to judge the size and kind of prey as well as relative distance through sound. This is why flies and lures that pop, whir, rattle or gurgle are so effective. The sound gets the bass' attention. Bass are always listening for prey that is in distress and vulnerable. When the bass is alerted by sound it will stalk by sound until visual contact is made. Fine tuning the attack is done after the prey has been sighted.

Pale Morning Dun Mayflies are very
small. Most species that
hatch on the Deschutes River in July are size eighteen.
It can take vast numbers to make a meal. Some trout feed on them voraciously. They are obviously very tasty.
However, the trout concentrate only on certain stages of the
hatch. Some trout,
especially during the early part of the hatch, hold tight to the tops of
weed beds. Here they take the slim red-brown and olive nymphs as they
emerge from the vegetation. These
nymphs are so tiny that the fish work at extremely close range. Often the feeding lane is less than a foot wide.
These lanes are always positioned in line with the maximum
concentration of insects.
Many holds are textured valleys
worn away by the abrasion of the currents.
Often these weed beds are situated near the shore in soft smooth
flows. A sneaky approach
and careful observation will disclose trout making sporadic swift
attacks while rarely moving more than a foot in any direction.
A size sixteen unweighted Pheasant Tail
Nymph is a deadly imitation for this stage of the hatch, but only if
fished precisely. The fly
must approach the fish with absolutely no drag.
It must be in the feeding lane and on the troutís level to
bring success. Study the
currents carefully before you cast.
Place your fly upstream, mend your line, and let the fly come to
the fish. This is most
easily accomplished when fish are within close range and holding in
relatively shallow water. These
fish are often spooky, and the angler gets few second chances.
Once Pale Morning Dun nymphs leave the
bottom and are dispersed among the currents, they become hard to see and
are therefore difficult to catch. The
trout tend to ignore them and concentrate on the surface tension.
Here the nymphs fight their upper thorax through the meniscus.
Their backs split open and the adult insect crawls out on top of
the surface film. Some
hatch easily, while others have problems making this transition.
All are helpless during the state of transition from water
breathing to air breathing existence.
All are easy prey. Many trout prefer to intercept these hatchlings at the exact
moment they are most vulnerable. They
can neither swim nor fly.

|The main stem Sandy has been running clear. Look for this situation to change if the weather warms. Hatches in the clear upper basin tributaries have increased with the warm weather. Both rainbows and cutthroats have been caught. Some fish are over 15", but few fish exceed 11". A short hike can bring much solitude and these little fish are like jewelry.|
