Introduction
Presently, the world is affronted by overwhelming association
of catastrophes: the post pandemic long-term effects, the ongoing
climate changes impacts, and the armed conflicts and violence,
which affect millions around the globe. The scores of multiple social
risks are worsening and, in most places, progress has been too slow,
and is further threatened by the health, economic, and environ-
mental crisis. Natural disasters, large-scale uncontrolled migration,
severe instability among some countries, decay of social cohesion,
biodiversity loss and ecosystem collapse, severe mental health deg-
radation, collapse of supply chains, are just among several global
risks, but on top of all these we rate primarily the rising cost-of-liv-
ing and food and clean water availability to be the most dramatic, at
least in Africa [1]. Africa is struggling with development challenges,
particularly chronic food insecurity and widespread poverty. Actu-
ally, some 300 million people in the continent experience chron-
ic hunger leading to malnutrition and associated potential health
risks. If African diets are basically reasonable covered on energy
requirements with staple foods rich in soluble carbohydrates, the
protein fraction relies on multiple local bean sources since meat,
eggs, fish, and seafood are of more difficult access and expensive
for the average indigenous. Fish has been the world’s single-most
trade value food commodity followed by soybean, wheat and coffee,
while for FAO fish is the second most traded food commodity in the
world after the collection of all cereals [2].
While few heads of cattle, goats, pigs, and poultry are frequent-
ly used by family farmers in Africa, and raised either to sell in local
markets or consumption in festive days, a possible good supplier of
high quality protein may be through aquaculture production of the
African catfishes Clarias gariepinus and Heterobranchus longifilis. In
Sub-Saharan Africa these two species are the most widely distrib-
uted fish in Africa and have been produced for a long time; they can
be differentiated by the lighter colour and a belly off-white and dark
olive brown dorsal of the H. longifilis. These are types of freshwa-
ter demersal or ground fish, air breathing catfish, sharp tooth scale
less mudcat, the most widely distributed in Africa, that exists in the
wild but it is also cultivated in ponds, cages, and pens and is of great
commercial importance (Figures 1,2). These omnivorous fish with
a preference for a planktonic diet, may weigh up to 60 kg and grow
to a length of 1.5-1.7m [3]. Being able to survive in shallow mud for
very long periods of time, between rainy seasons, this air-breathing
catfish with a scale less, bony elongated body, it feeds, relying on
vibrations and smells in search of food, on other types of food items
such as insects, insect larvae, pupae, fish, detritus, and fish remains
[4].
