Title: CHANNEL CATFISH CULTURE


1
CHANNEL CATFISH CULTURE IN THE UNITED
STATES BY Leonard Lovshin Department of Fisheries
and Allied Aquacultures Auburn University, AL

2
Channel Catfish ( Ictalurus punctatus )
3
Native Range Of Channel Catfish In The United
States
4
Food Habits
5
Preferred Habitat
Reservoirs and lakes
Rivers
6
MaximumWeight
  • The world angling record is
  • 58 lb caught in Santee
  • Cooper reservoir, South
  • Carolina

7
Reproductive Life History
  • 1. Sexual maturity is reached in 2 to 3 years in
    the southeastern U. S.
  • 2. Spawning takes place in a cavity formed by
    rocks, logs or a hole in a lake or river bank.
  • 3. Preferred spawning water temperatures 70 to
    84 F, with optimal temperature 75 to 79 F.

8
Sexual behavior
  • 1. Males defend a territory/cavity.
  • 2. Female enters the cavity and spawns.
  • 3. Males incubate eggs and defend fry.
  • 4. Males can spawn with more than one female a
    season.

9
Levee ponds
Hillside pond
Flat pond bottom
  • Catfish are grown in 10 to 25 acre earthen ponds
  • with flat bottoms.

10
Catfish ponds are filled with either
Filtered surface water or rainfall
Well water
11
Spawning in captivity
  • 1. Stock adults 3 to 8 years old
  • 2. Stock 1 male to 2 females
  • 3. Stock 800 lb of brooders/acre

Spawning Containers
Ammo cans
Milk cans

Wooden box
Boxes in spawning pond
13
Spawning occurs during May and June in the
Southeastern U. S. Spawning cans are checked
every 2 to 3 days for spawns.
14
Hatching Shed
Eggs are transported to a hatching shed.
15
Eggs are placed in 5-mm square wire mesh baskets
suspended in a paddlewheel incubator.
16
Eggs hatch in 5 to 6 days at water temperatures
of 75 to 80 F.
17
Fry are placed in screen boxes or troughs for 7
to 14 days before stocking in ponds. Fry are fed
powdered feed.
Screen bottom boxes
Fiberglass trough
18
Fry are stocked at 60,000 to 100,000 acre and
grown for 5 months.
19
Fry are fed powdered, crumbled andpelleted
feeds.
powdered
Large crumble
Small crumble
20
Fingerlings are stocked in fattening ponds during
January to March. Stocking density is 6,000 to
8,000/acre.
21
Catfish feed is purchased by the bag or delivered
in bulk and stored in silos.
22
Floating pellets are distributed by a feed blower
mounted on a truck.

Trucked mounted fish feeder
23
Feed amount is controlled by an electronic
scale located in the truck cab. Catfish are fed
what they will eat up to a maximum of 100
lb/acre/day.

Scale controls
24
Dissolved oxygen concentration is checked night
and day to assure that levels remain above 2 ppm.
25
Electric ( fixed ) and tractor ( mobile ) powered
paddlewheels are used to increase D. O. levels.
No water exchange is practiced because ponds are
large and pumping water is costly.
26
Low D. O. can kill catfish within 1 or 2 hours.
27
Many diseases cause fish mortality.
28
Birds consume many fish in some regions.
Shoo !
Gas cannon to scare the birds
29
Catfish are removed from the pond with a seine
stored on a hydraulic reel powered by a tractor.
30
Management systems used
  • Mono-harvest
  • All catfish are removed from the pond when they
    reach 1 to 2 lb, 6 to 12 months from stocking.
  • Ponds are drained yearly.
  • 2. Multi-harvest
  • Only catfish larger than 1 lb are removed by
    partial seine harvest.
  • Ponds are restocked yearly with small catfish.
    Large and small catfish are in the pond together.
  • Ponds are partial harvested 2 to 3 times per
    year. Ponds are drained every 5 to 8 years.

31
Catfish are retained in a holding net overnight
to eliminate small catfish. Fish are crowded for
loading onto the transport truck. A crew of 5 can
load 35,000 lb of fish in 1 hour.
32
Catfish are weighed onto trucks taking the fish
to the processing factory. Each basket holds up
to 2,000 lb of fish.

33
Fish are checked for off-flavor 2 weeks, 1 day
and upon arrival at the processor. Off-flavor
fish are not harvested.
34
Catfish are weighed a second time upon
arrival at the processor. Fish arrive alive.
35
Catfish are cleaned, filleted and frozen by the
processor.

37
The catfish industry maintains a quality control
program to insure the consumer a fresh and
healthy product.
38
Principle farming states are located in the
Southeastern U. S.. Mississippi ( MS ) Alabama (
AL ) and Arkansas ( AR ) produce 90 of the
farmed catfish.
Mississippi accounts for 65 of farmed catfish
39
The channel catfish industry developed in
the Southeast because
1. Popular food fish - market
2. Warm climate
3. Abundant water and clay soils
4. Close to major grain farming regions - cheap
fish feeds

Pond yield
4,000 to 7,000 lb/acre/year
