largemouth bass. The different
characteristics of Florida and northern
largemouth bass can be used to
increase the stocking success or for
different management objectives. For
example, northern largemouth bass
are more adapted to cooler climates
than Florida largemouth bass that
evolved in a warm climate. Stocking
northern largemouth bass in northern
areas of the state, especially the
Panhandle, would be one way to take
advantage of these differences.
Differences in catchability between
Florida and northern largemouth bass
may also be used to achieve manage-
ment objectives. Florida largemouth
bass are generally less likely to be
caught than northern largemouth
bass. Differences in catchability also
exist within each subspecies.
Stocking Priorities
Stocking requests of fisheries
managers frequently exceed the
production capacity of Texas
hatcheries. When this occurs,
stocking requests are prioritized
according to standard criteria. These
criteria were established to ensure
available fish were directed to
waters that offer the greatest
potential for achieving management
goals. Largemouth bass will not be
stocked into waters where they will
have an adverse impact on state- or
federally-listed threatened or
endangered species.Priorities for stocking are as follows:
1) Research evaluations - Stocking
requests for research purposes
tend to involve relatively few
fish, and knowledge gained
through research can have wide
applicability.
2) New or renovated reservoirs -
Stocking largemouth bass into
these types of waters is usually
successful in establishing initial
year classes that lead to natu-
rally-sustaining populations.
3) Restoring populations decimated
by catastrophe - Catastrophes
such as oxygen depletions or
pollution can occasionally
eliminate fish populations. If the
chance of a recurrence of the
catastrophe is low, largemouth
bass will be stocked to re-
establish the population.
4) Existing reservoirs - Most
stocking falls into this category.
District biologists prioritize fish
stocking needs within their
district. Program directors and
the Austin administrative staff
discuss these priorities and
decide on a statewide list.
Information used for prioritizing
requests includes: angling
pressure, projections of large-
mouth bass recruitment in the
absence of stocking, levels of
Florida largemouth bass genetic
influence, and expected survival
of stocked bass based on
availability of food and habitat.
The current target for Florida
bass genetic influence in
reservoirs is 20%. This includes9
