Summary: | Silver sharkminnow (Osteochilus hasselti) is one of freshwaterfish species
which potential to be developed. Information regarding morphological dan genetic
variations are required to support Silver sharkminnow farm. The aims of this study
were to know morphological and genetic variation of Silver sharkminnow from
Serayu River and Pandak Fish Hatchery Purwokerto. Silver sharkminnow samples
were collected using survey method with purposive sampling. Fourty samples of
Silver sharkminnow from Serayu River and ten samples from Pandak Fish
Hatchery were collected. Fifty three morphological of fifty Silver sharkminnow
samples were observed. Fourteen molecular characters of twenty four Silver
sharkminnow samples were observed using PCR-ISSR (Polymerase Chain
Reaction-Inter Simple Sequence Repeat) method. All collected data analyzed using
MVSP 3.22. Dendogram resulted by morphological characters analyzis showed
three cluster. The highest similarity percentage value was Serayu-Banjarnegara and
Serayu-Banyumas population (95,918%). Dendogram resulted by molecular
characters analyzis showed three cluster with the lowest similarity percentage was
Pandak Fish Hatchery population. The conclusion of this research is morphological
and molecular variation generated 3 cluster of Silver sharkminnow population. |
