The
cardinal objective of any commercial catfish farmer is to raise fast growing
fish that are at the same time healthy. This objective seems easy but for the
experienced farmer, it is not. There are a few but important things that you
must do; especially right from the beginning. Ordinarily, when properly
managed, the fish will be in good health and grow both uniformly and rapidly.
In order to ensure these, the following has to be taken care of.
Spacing. Higher than
necessary stocking rate can only guarantee one thing and that is failure. The
fish need adequate space to grow well and be in good health. Therefore, as a
beginner, you need to take seriously the recommendation stocking rate for fish
tank, cage and pond. Ordinarily, it ranges from 5.5 fishes per square foot (at
1 foot water depth or better still 1 cubic foot) fishes for tanks and troughs/vats to 3 fishes
for medium to large earth ponds
Sorting and Grading. Sorting and grading
should be done at least twice; at the end of the first month of stocking and at
the end of third month of stocking.
Others:
Water change should be regular and as recommended.
·
Feeding
time, quantity and strategy should be adhered to
·
Feed
fish with a feed whose crude protein content is not less than 40% for the first
three months and should not be less than 30% by the sixth (6th)
month.
·
Snack
meals such as animal wastes should be parboiled and given at intervals if
available
·
If
you are compounding your own feed, adequate growth promoters such as
methionine, lysine, fish premix etc. should be added to the ingredients
Medication: this is another important
factor that should not be over looked. Most fish coming from hatcheries are
disease carriers; and as such, they will not grow well, irrespective of their
feeding. Besides, when there are adverse conditions in your fish tank/pond,
they might easily fall prey to disease outbreak. In medicating your fish, there
are options that you can chose from but each has its own advantage and
peculiarity. Water medication is much common but not as effective as feed
medication. Whichever the option, there are procedures that you must follow to
make your treatment effective. Meanwhile, the treatment has to take place
within the first one to two weeks after stocking.
In our next
discussion we are going to consider feed conversion efficiency, feed conversion
ratio and how you can monitor the growth of your fish
