ABSTRACT
Six bacterial genera were isolated, which include; Pseudomonas aeruginosa, Bacillus sp, Micrococcus luteus, Escherichia coli, Proteus sp and Serratia marcasens. The total heterotrophic bacterial count showed that D1 had the highest count of 8.2 x 104 cfu/ml while F had the lowest count of 5.7 x 104 cfu/ml. The total coliform count showed that D1 had the highest coliform count of 6.9 x 104 cfu/ml, while CW1 had the lowest count of 4.4 x 104 cfu/ml. The percentage occurrence revealed that Escherichia coli had the highest frequency occurrence of 7 (28%) while Pseudomonas aeruginosa had the least frequency occurrence of 1 (4%). The antibiotic sensitivity revealed that all of the organisms are sensitive to some of the antibiotics used, the highest inhibitory activity of 22mm was recorded for Escherichia coli, Serratia marcasens, Proteus sp and Micrococcus luteus on Rifampicin, Ciprofloxacin, Gentamycin and Rifampicin respectively.

CHAPTER ONE
1.0 INTRODUCTION
Pond
water sources are useful for diversified purposes including aquaculture and
other related uses at the domestic level. Ponds are naturally formed by a depression
in the ground filling and retaining water. Streams or spring water is usually
fed into these bodies. A fish pond is an artificial lake (reservoir, pond)
intended for fish breeding. Fishes are the most popular animal cultured in the
pond. Fishes are among the edible food sources naturally living in water, consumed
by man and containing many nutrients such as protein, minerals, fat, oil, etc.
Fish ponds are constructed where fishes are fed and their growth are easily
observed and monitored. Fishes that are commonly produced in fish ponds are
catfish, tilapia and codfish, to mention a few (Bonde, 2007).
Water
is very essential in fish pond, water plays a vital role in the proper
functioning of earth ecosystem and also essential for fish and living creatures
for metabolism. The temperature of water supplied to a fish pond ranges from
25°C to 35°C as this supports the growth of the microorganisms and fishes found
in the pond. There are various sources of water, including well water, borehole
water, stream water, river water, etc., that can be supplied to the fish pond.
Some
bacteria coliform groups like E.
coli, in the ponds are transported from these sources of water or the media
of transportation into the ponds. Bacteria has a unique characteristics, they
are ubiquitous in every habitation on earth, growing in soil, acidic hot
springs, radioactive wastes, water and the live bodies of plants and animals
(fredrickson, et al., 2004).
Waste
water contains offensive and potentially dangerous substances which are mostly
of anthropogenic origin and causing pollution and contamination of receiving
water bodies (Ikpi and Offem, 2011). Fortunately, water can naturally renew and
cleanse itself via various physical methods: dilution, sunlight, aeration,
flocculation, sedimentation, biological degradation (decomposition), predatory
activities of microorganisms etc (Hanelore, 2013). This process of renewal is called
selfpurification and large bodies of water is said to possess self-purifying
capacity (Bitton, 2005). Contamination of water is a serious environmental
problem as it affects
the
different uses of the water. The use of indicator bacteria such as faecal
coliforms in water quality determination is widely applied. Coliforms and Escherichia
coli are of great importance among bacterial indicators used in water
quality assessment (Torimiro et al., 2014). One of the prominent uses of
surface water such as river, pond, run-off etc is in aquaculture which has
contributed immensely to the food sector and reduced the risk of fishes at the
brink of extinction due to excessive catch in lakes and oceans (Tidwell and
Allan, 2001). More than one fourth of all animal protein consumed by man is
aquatic in origin (FAO, 2000).
Aquaculture
has been practiced in many Asian countries for centuries, but is a new form of
agriculture in many African and Latin American countries. It is defined as the
cultivation of animals and plants in aquatic environments. Aquaculturists manipulate
certain components of the
environment
to achieve greater control on production of aquatic organisms (Purdom, 1996).
In Nigeria, the rearing of fish is helping in the
provision of food and its usefulness cannot be over-emphasized as the demand
for fish is expanding rapidly throughout the world (Ugwuba and Chukwuji, 2010).
There is an intricate relationship between the fish, their biotic and abiotic
environments
and changes in one component may reflect and affect the other (Wurt, 2000).
Pond water or water used in intensive fish
rearing contain many microorganisms which could be pathogenic or opportunistic
pathogen to fish, human, and planktons (Zmyslowska et al., 2003). These
contaminating microorganisms have been attributed to questionable water quality
which can be traced to the water sources and high stocking densities
(Okpokwasili and Akujobi, 1996). Water sources for earthen ponds are usually
untreated surface water runoffs from streams, rivers, lakes, stored waters
while underground water source is being utilized for most concrete ponds.
Water
from underground sources such as a well is pumped and stored in storage tank which
is used to refill the ponds when the water is to be changed at intervals of
about 3-5 days. The feed used for fish in these ponds contain organic materials
and introduces a wide variety of microorganisms into the ponds.
