VARIASI MORFOLOGI DAN KEKERABATAN IKAN NOMEI PERAIRAN KALIMANTAN SEBAGAI UPAYA KONSERVASI IKAN LAUT LOKAL DI INDONESIA
Abstract: Demersal fish is
quite important fish resources in Indonesia. One of the demersal fish that have
high economic value, namely Nomei fish (Local Name of North Borneo) and Lomek
(Local Name of West Kalimantan), which are both morphologically similar, yet
different location. Nomei fish catch has decreased since 2009. There has been
no real effort in the determination of conservation strategies. The purposed of
this study is to determine the taxonomic status of fish Lomek and Nomei based
on morphological characters as a basis in determining conservation strategies.
Morphological characters were measured morphometric, meristric, and special
characters determinant of species. Based on morphological characters, Fish
Nomei and Lomek identified as Harpodon nehereus (Ham.Buch). Special characters
are owned by both the fish is similar to the character of the holotype MNHN and
the key identification of Weber and Beaufort (1916) and Bleeker (1858) which
has long pectoral fins (reaching even exceeds the initial base of the dorsal
fin). The fifth character is chosen long tail rod (PBE), total length (TL),
high -fat fin (TSL), high head (HD), and height (BD). This is supported by the
results of PCA and cluster analysis that supports the grouping. In general,
fish populations Lomek and Nomei in both these waters is very critical, so it
is necessary conservation strategies to sustain its existence.
