| Growing big bass in little ponds By Dr. Wes Neal Wildlife and Fisheries Largemouth
bass are one of the most popular sport fish in Mississippi, and many
anglers chase these beasts on Magnolia State’s medium to large
reservoirs every day. However, little waters (one acre and larger)
can produce trophy bass consistently with a little help from the pond
owner. Growing big bass consistently requires
careful management. It is critical to follow water quality,
fertilization, aquatic weed control, and fish management programs
recommended by MSU Extension. The secret to big bass is through their
stomach! A lightly managed bass and bream pond occasionally can produce
a big bass, but you can increase your success by increasing food
available to each bass. This can be accomplished in three steps: Increase prey production by managing water chemistry and fertility. Add new prey species or supplement prey. Manage bass size structure and abundance through removal of small bass. Prey
production can be increased through proper water chemistry and pond
fertilization. Check to see if the lake needs agricultural limestone
and consider implementing a fertilization program. Trophy bass ponds
can benefit from a properly conducted and maintained fertilization
program, as fertilizing can double or triple the pounds of fish per
acre, which can be manipulated to produce bigger bass. Two
additional prey species are commonly recommended for supplemental prey
in Mississippi bass ponds. These are fathead minnows and threadfin
shad. Fathead minnow are good prey for bass and have no negative
impacts on the pond community. However, these fish are quickly
eliminated from Mississippi ponds by bass predation and must be
restocked often. They are also less tolerant of hot summer
temperatures, so it is best to stock this species fall to spring, when
water temperatures are cooler. Stock at least 2-3 pounds of minnows
per acre as needed. Threadfin shad are excellent
forage fish for largemouth bass and provide abundant prey year after
year. Threadfin shad are cold sensitive, and will die when water
temperatures fall below 36°C. This may occasionally result in
threadfin shad die-offs in northern Mississippi during the coldest
winters. Threadfin shad will need to be restocked the following
spring. Threadfin shad may compete some with bream, so they should
only be stocked in ponds where trophy bass is the management objective. Threadfin
shad should only be purchased from licensed distributors to ensure
proper species identification. Shad should never be collected from the
wild, because it is very difficult to distinguish threadfin shad from
gizzard shad! Gizzard shad should not be stocked in ponds because they
tend to grow too big for bass to eat; they can overpopulate, and will
compete with other prey species. Producing big
bass requires a commitment to proper harvest of bass. The biggest
mistake made in bass management is catch and release of all bass.
Small bass need to be harvested to allow for fast growth of
intermediate size bass. Bass should not be
harvested during the first two years following stocking, but beginning
in year three, harvest 15-20 pounds of bass per acre each year that are
less than 12 inches. Removal of these small bass reduces competition
with remaining bass, providing more food for those that remain. Also,
remove 5 to 10 pounds of bass per acre that are 12 to 15 inches each
year. Release all bass over 15 inches unless they are harvested as a
trophy. Harvest bream as desired. Following
these recommendations, you can greatly improve your success at growing
big bass in little ponds. Catching them is up to you! For
