Ultraviolet Light (Crepuscular Rays)
Did you ever wonder why some of the best fishing anywhere
in the world is done during dawn and dusk?

Fish mostly see in the Ultraviolet spectrum (crepuscular rays), and can see
some visible light. Did you ever wonder why some of the best fishing anywhere
in the world is done during dawn and dusk? It’s the closest to their world
we humans will ever get to being able to see into the ultraviolet spectrum,
which is why we should fish those times as often as we can.
During the hours just before dusk, an angler in the dark will be able to see
slivers of light as they peek through the tree tops. As the light transitions
from dark to light visibility increases dramatically allowing anglers to actually
see into “some” of the U.V. spectrum. This is the best time to change
up the leader to an offering that is easy to see in this light. Ironically,
if you can see the offering in this light so will the fish. This easy trick
will dramatically increase your chances of getting a hookup within just a few
casts.
Conversely, anglers who opt to fish during the waning hours of the day have
to reverse their offering processes since it’s harder to transition from
light to dark. As the sun dips below the treetops pick an offering that has
not been used during the heart of the day; two things put fish on the bite:
one, since it’s something new being tossed out fish are more apt to readily
strike due to fishing pressure; two, if you can easily see the offering in the
waning light so too can the fish making it that much more enticing.
If the water clarity has unlimited visibility during the day fish will be able
to see beyond the surface of the water and may very well be able to spot you.
As daylight increases and decreases during dawn and dusk it’s nearly impossible
for fish to spot you no matter how close you are to the fishable water.
Once you know what fish see then you too will hook into fish hand over fist,
or fish, whichever you prefer.
