Variasi Morfologi Kerapu Hybrid Cantik (Epinephelus fuscoguttatus X Epinephelus polyphekadion) dengan Populasi Asal Berdasarkan Penciri Morfometrik dan Meristik
Hibridization impact on increasing diversity of many grouper. Increasing diversity, increasing morphological variation. This diversity can be expressed by meristic and morphometric. The aim of this observation was to know the variation of morphological between cantik hybrid grouper and the wild type, tiger grouper and camouflage grouper based on morphometric and meristic character. Morphological variation analysis was performed descriptively based on pigment pattern. Quantitative analysis of meristic was performed based on the number of spine fin. And morphometric was performed based on total lenght of whole body and some part of body. The observation showed that pigment pattern of cantik grouper has similarities with camouflage grouper. In meristic, showed that soft spine of dorsal fin can be used as distinguishing character between cantik grouper and the wild type (tiger and camouflage grouper). In morphometric, head proportion of cantik and camouflage grouper was tend to similar with correlation value 0.9975. Furthermore, body proportion of cantik and tiger grouper was tand to similar with correlation value 0.99979. And based on correlation on overall proportion of comparison morphometric character, cantik grouper has similarities to tiger grouper with correlation value 0.995637.
