WHAT TYPE OF SPACE
DO I NEED TO GROW MY FISH?
This is a continuation of my previous post last week on the question, what type of space do I need to grow my catfish?
Raceways are increasingly becoming the most popular water facilities in Nigeria for raising fish. A good number of the most productive farms most especially in the urban areas use this type of facilities.
Raceways make use of flowing water. It may well be a long narrow construction or a series of constructions, through which water flows. The water may flow through naturally, or forced to flow by the use of pump.
The semi-raceway is the most popular one here in Nigeria. The water is made to flow through slowly. The foremost advantage of raceways is that catfish can be stocked in them in high population per area of land than in ponds.
‘Open’ or ‘flow’ through raceway are raceways in which the water enters at one end and is disposed of at the other end. The water is not reused. Flow through raceways can accommodate up to 50 – 70 fishes per square meter.
‘Closed’ raceways are raceways in which the water enters at one end and is removed at the other end and filtered, aerated and reused again and again. Usually most closed raceway are not completely closed but are ‘modified closed’.
In closed raceways pumps are used to circulate the water hence, more energy is required in raceway culture than pond culture. This type of fish farming can be very profitable under close and thorough supervision.
Also popular in Nigeria is the use of tank especially the plastics type. Their shapes may be rectangular or circular and could be closed or open like in raceways. Therefore they are also useful for very intensive culture.
Remember, that proper identification of the type of space you want to use to grow your fish is very important.
