Abstract:
This study is one of series of paper expected to occur in this journal (Part
of my PhD work Moi University2014-
17)
. The study conducted between January 2016--June 2016 involved three counts, Kirinyaga, Kisii, and
Uasingishu of Kenya
, with the aim
to investigate problems
of stunted and mortality of
520 fishes of these two
species of fresh water from farmer ponds were randomly
sampled and examined for internal cestode parasites.
100 fish were C. gariepinus and 420 O. niloticus.
These
specimens were killed by scissors or a knife and then
dissected
internal organs placed in Petri dish
mixed well with sodium chloride solution different parasi
tes
observed and identified
using common characteristics and
standard keys
.The over roll results show that 240
(46.2%) of the total fish examined were infected by di
fferent parasites. C. gariepinus had a higher infection rate
55(55.0%) out of the 100 fish sampled compared to O. niloticus 185 (44.1%) of the 420 fish sampled.
Prevalence and diversity of internal parasites. Diphyllobothriumlatum(34.59%), Proteocephalus s
pp(49.62%),
Caryophyllidea spp(13.53%)
and
mixed infection (2.26%) Statistically Significance was tested at 0.05,
The study
findings show t
that there was a significant relationship ( p=0.0002) between the type of fish and the number of
parasites
Also in
significant
Relationship
observed
between
internal cestode
parasites and sampled fish on length
(0.06657), weight(0.1690) a
nd sexes(0.3668).
The
study concluded that the C.
gariepinus are
more attacked
by internal cestode
parasites compared O. niloticu
s. Our study suggest that farmers to keep more species with
higher tolerance with parasites.
