DNA barcoding and morphometric of Rastrelliger spp. in North Maluku Sea, Indonesia

High exploration activity is feared to have an impact mackerel populations. A sustainable management approach should be taken provide information about the status of Study population can carried out through genetic information. The DNA fish samples were collected at traditional markets (Morotai, Bacan and Ternate). Laboratory works such as extraction, amplification, electrophoresis sequencing analysis Indonesian Biodiversity (Bionesia). molecular characteristics Rastrelliger kanagurta 374 base pairs (bp). composition nucleotides showed similarity frequencies between species. Phylogenetic relationship R. in North Maluku Sea suggested that there was any differentiation. diversity high with a total number haplotypes diverse nucleotide diversity. minimum spawning networks (MSN) found 5 haplotype from 12 samples. Morphological measurements standard length, head height, body width, pectoral fin length tail variable values. weight obtained b = 3, indicating growth pattern isometric or gain equivalent length.Keywords: Biodiversity, conservation, ecology, morphology, species
