Spawning Bed Fishing Controversy Won't Die Easily M. S. Allen, Fisheries and Aquatic Sciences, The University of Florida
 

Summary: Spawning Bed Fishing Controversy Won't Die Easily
M. S. Allen, Fisheries and Aquatic Sciences, The University of Florida
There is an ongoing controversy around the practice of catching bass off
spawning beds. The concern centers on the possibility that such fishing activities could
lower juvenile bass production and reduce the number of bass that recruit into the adult
population. Addressing this question will be a challenge, and it's one that we need to
meet.
Several well done studies by Dr. Dave Phillip and his students at the Illinois
Natural History Survey have shown that removing a fish from a spawning bed can reduce
the nest success for that spawning pair. Removing adult bass for a short time or
transporting the fish to a tournament weigh in can reduce the fry survival for that nest.
The question that has not been answered through research is: what are the implications of
these losses for black bass populations? We have not evaluated the impacts of reduced
survival via bed fishing on bass recruitment at the population level or adult fish
abundance. Why not? Because it's not easy!
The tough issue is that fish survival and recruitment to adulthood is a very
complex process. Most fish, including black basses, produce very high numbers of eggs
and larvae, but mortality during the larval and juvenile phases is also very high. The vast
majority don't survive, and mortality of bass fry usually exceeds 99%. In any given year
there are many more fry produced in lakes than will ever survive, and more produced
