To avert the Malthusian trap of
exponential trap of exponential population growth are the expense of logarithm
food production and to produce proteins' diet at lowest cost; fish production
till remain the cheapest source of animal protein is the best option to exploit.
The pressure of a growing world population on a national resources in general
and the fishery in particular has rise to the specter of Malthusian stagnation and
even the possibility of collapsed of civilize life to our planet. A world
population the current double every 35year will raise more and more dispute
over such common property resources and fisheries. This is why alternative
method of fish production is to be encouraged to cash up with the teeming world
population. Priorities should be given in the area of procurement of research
facility and the development of laboratory for disease identification monitoring;
control, prevention and generic improvement.
Tremendous effort has to be
injected in the human capacity building on fishery with a viable extension
network to support the dissemination of fish production innovation at least
cost with simple adaptive technologies.
Aquaculture or fish farm is the
rearing of fish in an enclosed water environment with the aim of achieving
height possible fish production in a given circumstance in the most economic
manner. In some area the country especially the northern part where there is
relative low and erratic rain fall and almost absence of large water bodies,
these technology will be a tremendous advantage, these sub-sector wish is still
virgin are with respect with great potential with economic gain need to be
given priority consideration.
It is heart rendering to know
that out of 2.5 million metric tons aquaculture potential in Nigeria, only 25
thousand to 300 thousand(25K-300K) capacity productions is currently available.
Also out of the 4.3 billion annual fingerling requirements, only about 55.8 million
total fingering supplies is currently available. The wide gap between the 4.3billion
requirements and 55.8 million currently available stands as a virgin opportunity
of investment of fish farming. Presently Nigeria import 7000 metric tons of
domestic consumption fish, yet it cannot cash up with domestic of her teeming
population.
CAPACITY BUILDING IN FISH FARMING
The fish industry still most
virgin investment in Nigeria compared with the importation frozen fish in the
domestic market. Local production has to be supported to increase domestic
production and by extension attract foreign investors to the subsection of the
economy that has badly neglected over the years.
Source of animal protein is a
delicacy at all levels of production, eggs, fingerlings and grow out table-size
fish, this provides opportunity for investments. The fish industries still
remain the most virgin investment in Nigeria compare with the importation of
frozen fish in the domestic market. Local production has to be supported vigorously
to catch up with the teeming population.
PROBLEM OF FISH FARMIN IN NIGERIA
Nigeria can raise her production
levels on fishery production: but the constraints to aquaculture and fish
farming development been debilitating. High cost of equipment for construction
of ponds, high cost and insufficient supply of quality fish seed as well as
shortage of competent, experienced technical and skilled manpower are some
major problems. Others are inadequate laboratory and research facility for fish
disease identification, monitoring control, control, prevention and generic
improvement. In the midst of all these challenges aquaculture and fishery
management is gradually getting better with widespread of new entrance of
individual in the form of workshops, seminars, conference, use as a medium to
disseminate the innovation to the public at adoption levels with simple
indigenous technology.
RECONNAISSANCE TOUR AND SITE SELECTION
Most marginal soil with poor crop
production capacities can be put into good through fish farming provide the
land is not too very porous and the terrain neither too hilly gravely, not too
flat.
TOPOGRAPHY CONSIDERATION IN FISH FARMING
The accepted and cost effective
topography for fish farming is that which allow the farmer to fill and drain
the ponds with the Aid of gravity.
RECOMMENDED TECHNICAL MEASURE IN TOPOGRAPHY MEASURE IN TOPOGRAPHY
For a land with valleys, upland
ponds may be established where natural valleys or hollow constructing a dam
across the narrow section to impound run-off from the overlaying watershed
In locations where the land is
relatively flat in terrain, lowland ponds are usually built by excavating the
site and constructing surrounding dikes
to impound water. In this regard, visual survey is not advisable especially in
large area, thus a topographic map showing contour lines is useful in determining
the size the ponds, location of dikes, draining outlets, gates height of dikes
among other features of the pond.
