A listener in Abuja, Nigeria, named
Okorie wants to know more about fish pond farming.
fish in ponds of standing water can work well on a traditional farm. Animal and
crop waste can be used to fertilize the pond and feed the fish. And mud from
the bottom of the pond can be used to fertilize the crops. Also, water for the farm
can be stored in the pond with the fish.
say ponds with a surface area smaller than one hundred square meters may not be
profitable. But those larger than one hectare may cost too much and be
difficult to manage.
farming is one kind of aquaculture. Other fish farms are connected to sources
of free-flowing water -- a lake, river
or ocean. This way you may not have to feed the fish. They can eat weeds and
small organisms, like plankton and algae. Fish can also be raised in tanks,
either indoors or outdoors.
which kind of fish to raise depends on the water quality, salt content and
temperature. The best idea, experts say, is to raise fish that normally live in
the source of water that you use. Also, you should remove wild fish, or else
they could eat your fish.
Common carp are a popular choice for a
fish farm. You could also raise tilapia, catfish, grouper, milkfish, eel or
other kinds, depending on where you live.
Some fish are harvested once a year; other kinds can be harvested
throughout the year.
Martin Schreibman hopes more people will raise their own fish. He started the
Aquatic Research and Environmental Assessment Center at Brooklyn College in New
York. He says setting up a fish farm is easier, less costly and more profitable
than people might think.
Intensive fishing has reduced populations of wild fish.
The aquaculture industry now provides almost half the fish eaten worldwide. Fish
farming is seen as an important way to help feed a growing world. But fish
farms also require attention to environmental and food safety considerations.
Nations Food and Agriculture Organization released a State of World Aquaculture
report at a meeting in New Delhi two years ago. At that meeting, delegates
agreed on the need for more support for aquaculture development in Africa. The F.A.O.
said Africa was the only area of the world where in recent years people have
been eating less fish instead of more.
