| dc.description.abstract | Belumai river is one of river in Regency of Deli Serdang, Province of North
Sumatra. One of fish resource potency in Belumai river is Lemeduk fish (Barbodes
schwanenfeldii). The objective of this research is to study the morphometric
characteristic and meristic range of Lemeduk fish and to observe the morphometric
diversity of Lemeduk fish in Belumai river.
The calculation of morphometric character using Principal Component
Analysis. The results of Principal Component Analysis indicates that the more of
information are found on the both of first main component with cumulative 84.3%.
All of morphometric character has a role on first principal component and second
principal component. The character with a role to the second main component as
character that influence the morphometric diversity is the Length of base of the dorsal
fin and eye diameter. The principal component analysis indicates that lemeduk fish
on four stations did not indicates classification (shape diversity). This indicates that
the observed fish is one of population unit. On the calculation of phenotype range
value of each character of lemeduk fish indicates that morphometric character with
the higher range value is total length (PT) and the lower is eye diameter (DM), while
on meristic character calculation found the radius of fin is DIII.9, AIII.6, VI.8,
PL,.13-14. | en_US |
