| description | Genetically Improved Farm Tilapia (GIFT) strain was developed through
selective breeding of Nile tilapia and was cultured worldwide due to its ability to
tolerate wide range of water conditions. There were limited studies on the effects of
spawning agent (to induce maturation and increase milt production) on seminal
characteristics of GIFT strain. This study was carried out to determine the effects of
different doses of a spawning agent (Ovaprim®) on seminal characteristics of GIFT strain as well as to determine the optimum dose of the spawning agent. There were four
treatment groups which consisted of 0 (control), 0.1, 0.3 and 0.5ml/kg and the body
weight was between the range of 200 to 360 grams. The fish was injected
intramuscularly and the milt was collected after 12 hours (latency period) through gentle
abdominal pressure. The volume of milt was recorded and sperm parameters such as
sperm density, motility, viability and morphometry were evaluated. There was
significant difference for sperm motility but other parameters were not significance.
Treatment group 0.5 ml/kg has the highest mean for sperm density, motility and
viability, which made it as the optimum dose for Ovaprim®. Thus, these parameters are
usually being used to determine the sperm quantity and quality. |
