3.  Cat fish farming is an Important Agriculture in the usa,with More than 60,000 acres
of water devoted to Catfish production .These Catfish are grown under several
production system.
 Careful planning is an important of any operation.
 A well designed Catfish farm is the result of proper planning to suit individual needs.
 Cat fish farm planning and application assistance is available from the soil
conservation service.
Introduction

4. Method’s of farming
 Pond culture is far the most common type of cat fish Production .
 Cat fish farms may range in size form 60 acres or less to 640 acres or
more depending on available resources.
 Careful attention to pond size and design elevation of drain pipes and
adequacy of out lets and spill way is important.
 Do not locate ponds on lands where pesticides have been regularly
applied to crops, especially to cotton.

5. 2.Cage
 Cage culture of Channel cat fish represents only a small fraction of
the total farm raised catfish production.
 Although cage culture has limited popularity ,it has potential in
bodies of water where conventional harvesting method are
impractical.
 Place in open water and anchor posts or cables .
 The cage bottom should be 2 to 3 feet above the pond bottom.
 The amount of fish produced in cages will be about the same as
traditional open Pond culture.

6. 3.Race way culture
 A fish raceway system especially designed for fish prodution consists of a
series of long ,narrow channel through which there is a continuous flow of
water .
 Raceways are Systemly used for trout production but their used in
commercial cat fish production has been limited.
 Raceway culture of channel cat fish requires more intensive management
than pond culture .
 Serious handicaps to raceway culture are higher requirement's for water
quantity.

7. Key factors of catfish farming
1.water source
 The best source of water is well .use of well water avoids
problems of unwanted fish .
 Water from wall measured in gallons per minute (gpm)
and pond volume measured in acre feet .
 Thus a 1000 gpm well yield 4.4 acre feet in 24 hours .
 The well yield determines the size of an enterprise.wells
should provide enough water to fill the ponds .
 Fish farming using less water are practical at lower level
of fish prodution .

8. 2.Water quality
 Water quality includes all physical, chemical and biological factor
the influence the beneficial use of water .
 Maintaining good water quality is vital to success full catfish
farming.
 Water quality characteristics include Ph ,total hardness ,dissolved
oxygen and temperature.
 The desirable Ph between 6.5 and 8.5.Dissolved oxygen Is a critical
water quality characteristics in fish farming .

9. Cost of cat fish farming
 Construction facilities
pond construction is a major expense .The kind pond built may
be most important decision made in catfish farming. Cost
depends on the kind of equipment used ,the cost of moving soil
and shape and size of the pond .small rectangular or odd shaped.
Water
Water is another cost of item .The kind of pond built. Well are
generally preferred a source vary is cost according to size depth
to water table ,geologic structure and other factors.A6 or 8 inch
well that produces 1,000 to 1,000 gallons per minute usually
provides enough water 40 acre of pond.
