MANAGEMENT IN FISH FARMING

The purpose of fish
management is to provide good
fishing.
1. Removing Unwanted &
Over populated Fish: The best management option
when your pond becomes out of
balance and over populated,
may be to destroy all fish in the
pond and start over. Removing
or killing the fish population usually is much easier and less
expensive if the pond can be
drained. Fish will survive in
very small pools of water away
from the main body of water to
help treat your problem. Roten one is a registered aquatic
chemical that is used to kill fish.
It comes in liquid or powder
forms, and a concentration of 5
precent active ingredient.
Roten one should be applied at a rate of 10 ponds per acre-foot.
The volume of water in the
pond, must be estimated so this
concentration of roten one can
be calculated. One gallon of the
liquid form is sufficient to treat app. 1 acre-ffot. Powdered
roten one should be mixed with
water (about 2 gallons per
pound of powder). Liquid
roten one also should be diluted
with water at a rate of about 10 gallons of water to 1 gallon of
roten one. Using buckets,
sprayers, or pumps, apply
roten one evenly over the pond.
Roten one applied properly and
at recommended rates will not harm most livestock. However,
pigs might be affected by the
formulation, and ducks and
geese may suffer if they eat
dead fish. Roten one is usually
applied in the summer or fall when water temperature is
above 70 degrees F. Roten one
will sissipate within 3 to 10
days, depending on weather
conditions. It is generally safe
to restock 2 to 3 weeks after applying the rotenone. To check
for the presence of roten one,
place a few small blue gill in a
min now bucket and float it in
the pond. If the fish are still
alive after 24 hours it is safe to restock! Before using roten one
it is best to contact a fisheries
scientist or for information in
purchasing, applying, and using
roten one. In Texas, roten one can be purchased from most
farm supply ot feed stores. You
must have a private application
license to purchase and use this
chemical.
