KERAGAMAN MORFOLOGI UDANG PAMA ( Penaeus semisulcatus ) DARI PERAIRAN SULAWESI SELATAN DAN SULAWESI TENGGARA
Abstract
Udang pama, Penaeus semisulcatus merupakan salah satu jenis krustase lokal yang memiliki prospek untuk dikembangkan sebagai kandidat spesies budi daya tambak. Penelitian ini bertujuan untuk mengetahui keragaman morfologi dan jarak genetik udang pama yang berasal dari Sulawesi Selatan dan Sulawesi Tenggara. Principle component analysis (PCA) dan discriminant analysis digunakan untuk mengetahui keragaman morfologi antar ketiga populasi alami udang pama. Hasil penelitian menunjukkan bahwa morfologi udang pama dari Munte dan Lampia (Sulawesi Selatan) berbeda dengan udang pama yang berasal dari Kassipute (Sulawesi Tenggara). Analisis kluster juga mengindikasikan adanya dua kluster utama, di mana kluster pertama merupakan gabungan antara udang pama dari Munte dan Lampia, sedangkan kluster lainnya adalah udang pama yang berasal dari Kassipute. Jarak genetik yang didapatkan memperlihatkan kekerabatan terdekat adalah udang pama yang berasal dari MunteLampia (5,424) dan terjauh pada udang pama yang berasal dari Lampia-Kassipute (48,350).
Green tiger prawn, Penaeus semisulcatus is one of the prospective local crustaceans as a candidate species of shrimp pond culture. The objective of this study is to reveal the morphology diversity and genetic distance of green tiger prawn from South Sulawesi and Southeast Sulawesi. Principle component analysis (PCA) and discriminant analysis were used to analyze morphometric variations among the three natural populations. Result showed that the morphology of green tiger prawn from Munte dan Lampia (South Sulawesi) was relatively different with prawn collected from Kassipute (Southeast Sulawesi). Cluster analysis also indicated the existing of two main clusters i.e. green tiger prawn from Munte and Lampia as the first cluster and Kassipute as the second cluster. The lowest value of genetic distance was obtained from Munte-Lampia (5.424) and the highest genetic distance was obtained from Lampia-Kassipute (48.350).
