A bass study bass anglers should read

[CCbass]

I am a wildlife biologist by degree and started researching studies of bass and prey relations. Most just went on about what bass eat, and when, I think as bass fisherman we all know that by now. This gives great insight of how they choose there prey and how the prey reacts to them. My thought the more you know them the easier to catch them. http://www.montana.edu/~wwwbi/staff/.../Pred-Prey.pdf

First, let me say welcome! I look forward to reading that piece. Thanks!

Welcome cant wait to read it all.

Oh ya forgot to mention its a little lengthy, but forth the read.

that is a very confusing Study. lol


I got a headache from it., and it happened when i tried to read that graph.

So true, I am a biologist and never did understand why we had to put graphs in the study ~, Maybe to give people headaches.

studies).

Generally, about 50% of the largemouth bass captured have

empty stomachs

no one has clearly demonstrated the behavioral mechanisms of

largexnouth bass predation.



Lawrence (1958) t0und that the maximum size of prey a largemouth bass would eat is limited only by the spacing between the esophageal cleithruxn bones.

The reaction distances of largemouth bass
preying on bluegills or redfin shiners in bright

ligfit increasedl i nearly with prey size

Prey motion also affected the distance at which
largemouth bass located prey, but only when

prey were small.

Based on measurements of largemouthbass
mouth width and fish prey height, Lawrence
(1958) estimated that the largest bluegill a 13-
cm and 22-cm largemouth bass could ingest
would be 4.9 and 7.4 cm, respectively. However,
we found that these two sizes of' large-

mouth bass could ingest prey of 5.5 and 9.5 cm.

These differences maybe of little practicacl consequence.

Wright (1970) found that largemouth
bass of two different sizes both preferred
small prey over larger ones. He suggested
that ease of capture, rather than ease of handling,
best explained these results because evasion
success of bluegills increases rapidly the
larger they are, the maximum prey size largemouth b*** can handle may not be as important in determining prey vulnerability

At high light intensitiesb luegillsc an locatel argemouthbass
before they themselvesc an be located. However,
at low light intensities (l.49 lux), largemouth
bass can see most bluegills further than

the predators can be seen.

Once a bluegill is larger than about 4 cm,

it becomes increasingly vulnerable to predators
until it grows too large to be handled and swallowed.

These relationships may place important
constraints on largemouth bass feedings. Big
largemouth bass ambush by day and cruise by
twilight, but it would be profitable for smallo bass
to cruise at high light intensity because many
encountered bluegills might be too large. Intermediate-
size largemouth bass might ambush
during bright light and then begin cruising at

lower light intensities.

Thank you WTL for reading a post from a newbe, and shortening the important facts of the study. The size part actually lead to a newer study, which I can not find but reproduced in a class in college. Preditors ( Bass included ) know instinctually energy expant for energy returnered. Meaning they know if they chase something to long or spend to much time to actually capture and ingest it they gained nothing from eating it.

Your signature is my hero. You are my hero.

I just want to say thanks for viewing and I hope this study helped in your bass knowledge.
