maturity is a function of time of existence and quality
of food intake. it was also observed during the present
study that sperm obtained from two broodstock of 600 g
and 556.6 g body weight having 2.9 g and 2.8 g testes
weight respectively were immotile when viewed under
the microscope, this according to McAndrew et al
.,
(1993), could be as a result of intratesticular aging of
spermatozoa which is a strong cause of variation in
sperm quality study.
Conclusion
The study has established the relevant equations to
predict sperm volume and motility given the body
weight of the fish, testes weight and sperm count. The
value of motility for predicting fertility has been proven
questionable because of the subjectivity of the
technician performing the analysis and the short
duration of motility following activation, fertilization
capacity however, is the most conclusive test of sperm
quality (McNiven et al.
,
1993), hence the need for more
research.
