Water Spouts will speak volubly and endlessly about all the issues concerning water. The ongoing degradation, and growing scarcity, of the water supply here in the US, and the rest of the world. The continued absence of potable water in so many parts of the world. The work being done by NGOs, and charities, in the third world, to help alleviate the situation. The emphasis on WASH ( Water, Sanitation, and Hygiene ) so health and healthy water are maintained. "Water Spouts" will spout it all out.
Catfish Farming Business in Nigeria by Oluwatomi Olatoye
Fish farming in Nigeria is currently a very lucrative business and it
is mainly boosted by the continu-ous rise in the demand for catfish.
This trend, therefore, makes catfish culture the most popular form of
fish farming in Nigeria and it is therefore where the discourse of this
article is going to be centred.
Whether you are just starting out in aquaculture with the hope of
making just an extra income or going into full scale commercial
production, Here you will discover the prospects and the challenges
facing the catfish industry in Nigeria.
Overview of fish farming in Nigeria Let me start by giving you a quick overview of the state of fish farming in Nigeria.
The most common species found in Nigeria are; Clarias gariepinus, Heterobranchus bidorsalis,
Clarias X Heterobranchus hybrid (Heteroclarias) and Clarias nigro-digitatus.
Heterobranchus sp are very common in the south eastern part of Nigeria with clarias spp dominating in the west.
Despite the popularity of catfish farming in Nigeria, the fish
farming industry can best be described as being at the infant stage when
compared to the large market potential for its production and
This is mainly due to unavailability of fingerlings owing to lack of
adequate infrastructure for hatcheries and fingerling production.
Breeding If you intend to go into catfish farming in Nigeria, the first thing you have to get hold of is the fingerlings.
The fingerling can be obtained mainly through artificial propagation in the hatcheries through hormonal induction.
If you intend to produce your own fertilized eggs, you can make use of the homoplastic pituitary gland suspen-sion.
In Nigeria, it is usually more affordable than the imported hormonal
analogues. Fish Farmers also say that they are more reliable. And I
seriously don’t doubt them.
But despite the beauty of induced spawning, there are challenges which you must face: both biotic and abiotic challenges.
These problems all have their root in the extra care needed to be
given to the fry during the first week of life. In this regard, you have
to battle with provision of zooplankton which serves as feeds for the
larvae, fry and fingerlings thus playing a major role on their growth
There is also the problem of cannibalism, heavy predation by
frogs/aquatic insects and the abiotic challenges such as water
temperature, dissolved oxygen (>4.5mg/L-1), levels of ammonia. The
brood stock to use for the purpose of breeding should be between 0.3kg
