“…The size of base pairs (bp) was the normal size of sea fish sequences, where the length of the base size in fish ranges from 200-1500 bp (Liu et al, 1999;Ali et al, 2004). Fragment length reported by Jayasankar et al (2004), Darlina et al (2011), Munpholsri et al (2013), Kielpinski et al (2014, Akib et al (2015), Indaryanto et al (2015 and Zamroni et al (2017) (Table 1). Fragment length (bp) was found to be short compared to other studies (Table 1).…”

Previous studies reported Zamroni et al (2007) found low genetic diversity (Hd = 0,000) on the North coast of Java (Table 10).…”

“…Even though this species was a target of conservation in each water, but with the ability to migrate and produce the fast tuna population can survive. Genetic diversity gives the ability to adapt to changes in the environment and climate and disease and showed the species has a large population size (Zamroni et al, 2017). is the main target species in fishing small pelagic fish categories, this is because this species is a fish that people consumption every day in North Maluku.…”

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

Tujuan dari penelitian ini adalah memetakan distribusi sebaran spasial dan temporal kegiatan perikanan terkait pertumbuhan populasi ikan dan strategi pengelolaannya. Terkait hal ini, Rastrelliger, terpilih sebagai spesies yang ditangkap di wilayah pengelolaan perikanan yang dikenal memiliki nilai ekonomi tinggi meskipun sebagai bycatch. Untuk Dalam menentukan strategi pengelolaan spesies ini, pemetaan merupakan langkah penting pertama dari kegiatan yang harus dilakukan. Pada bulan Januari sampai dengan Maret 2016 dilakukan Penelitian ini di Tempat Pendaratan Ikan (PPP) Labuan, Lempasing, dan Kota Agung dengan melakukan survey yang dilakukan melalui wawancara, purposive sampling dan stratified random sampling untuk sampel ikan. Hasil penelitian ini menegaskanadanya tumpang tindih wilayah penangkapan ikan,berdasarkan irisan satu fishing ground dengan penangkapan nelayan yang berbeda wilayah penangkapan yaitu di perairan Pulau Legundi, Belimbing, dan Kilauan. Korelasi antara bobot panjang Rastrelliger memilikipola alometrik negatif dalam pertumbuhan, ikan dewasa Rastrelliger kanagurta dengan ukuran kelas 18,03–22,09 cm (jantan) dan 19,10–19,52 (betina) dengan ukuran tangkapan pertama (Lc) menggunakan purse seineadalah 15,66 cm dan 18,67 cm (Lc<Lm artinya ikan tidak bertelur saat ditangkap). Alternatif strategi pengelolaan yang tepat adalah penutupan penangkapan disaat musim penangkapan untuk memberikan kesempatan bagi ikan untuk memijah.

Mackerel is a small pelagic fish that has potential value and can be found throughout Indonesian waters. It is feared that high exploration activities will have an impact on the population. Sampling was carried out at the fish landing port and fish auction place (Bacan, Morotai and Ternate). The sample was photographed and the 3 cm swimming fin was taken. The sample is then stored in a tube that has been filled with 96% ethanol solution. The next stage is the process of extraction, amplification, electrophoresis and DNA sequencing. Phylogenetic reconstruction of comparison of primary data (Bacan, Morotai and Ternate) and secondary data (Indian) clarified to form two different populations (clades). Amova population pairwaise (Fst) showed the genetic flow of R. kanagurta population in the waters of the north Maluku Sea (Bacan, Morotai and Ternate). On the other hand, genetic distance shows that populations (Bacan, Morotai and Ternate) were closely related and have strong genetic connectivity.
