“…Tuna sirip kuning (Thunnus albacares) adalah ikan komersial penting dan ikan ini hidup di perairan tropis dan subtropis (Wu et al, 2010;Collette and Nauen, 1983). Sibert et al (2006) Perairan Maluku Utara merupakan salah satu daerah potensial ikan pelagis besar khususnya ikan tuna (KKP, 2011).…”

“…Informasi genetik pada ikan dengan migrasi yang tinggi seperti tuna sangat penting diketahui untuk pemanfaatan yang bersifat lestari (Santos et al, 2010). Nilai komersial dan ekonomi yang tinggi ikan tuna sirip kuning menjadi alasan pentingnya pemahaman guna efektifitas pengelolaan sumberdaya perikanan yang berkelanjutan (Wu et al, 2010).…”

“…Panjang fragmen hasil penelitian ini sama dengan panjang basa (bp) untuk spesies tuna sirip kuning (Thunnus albacares) yang ditemukan oleh Kunal et al (2014) yaitu sepanjang 500 bp, namun lebih panjang dari yang ditemukan oleh Ely et al (2005) sepanjang 333 bp, Scoles dan Graves (1993) sepanjang 304 bp dan Wu et al (2010) sepanjang 366 bp, Chiang et al (2006) sepanjang 380 bp dari spesies tuna mata besar (Thunnus obesus), dan Martinez dan Zardoya (2005) yang menemukan panjang fragmen 409 dari spesies tuna mata besar (Thunnus obesus). Namun, sedikit berbeda dengan Niwa et al (2003) yang memperoleh total ukuran panjang basa 1900 bp.…”

“…Tingginya nilai keragaman genetik populasi ikan tuna sirip kuning yang ditemukan sama seperti yang dilaporkan oleh Scoles dan Graves (1993) di Samudera Pasifik (0,840). Keragaman genetik yang tinggi juga telah dilaporkan oleh beberapa penelitian lainnya diantaranya Moria et al (2009) yang memperoleh keragaman genetik ikan sirip kuning berdasarkan sampel larva sebesar 0,878, Wu et al (2010) keragaman genetik ikan tuna sirip kuning sebesar 0,992 di Barat Samudera Pasifik dan 0,999 di Barat Samudera Hindia, serta Kunal dan Kumar (2013) memperoleh keragaman genetik tuna sirip kuning sebesar 0,998. Hasil penelitian ini, mirip dengan laporan hasil penelitian ikan migratory pelagis lainnya seperti tuna albacore (Thunnus alalunga), tuna mata besar (Thunnus obesus) dan ikan cakalang (Katsuwonus pelamis) (Carlsson et al, 2004;Chiang et al, 2006Chiang et al, , 2008Martinez dan Zardoya, 2005;Martinez et al, 2006;Nugraha, 2009;Dammannaggoda, 2007;Suman et al, 2013).…”

Abstract. Yellowfin tuna (Thunnus albacores) is a large, pelagic, and migratory species of tuna that inhabits Moluccas SeaAbstrak. Tuna sirip kuning (Thunnus albacores) adalah ikan komersial penting dan ditemukan di Laut Maluku, Indonesia. Tetapi, aktivitas penangkapan ikan tuna sirip kuning dapat menurunkan kualitas dan kuantitas stok ikan, sehingga perlu adanya pengkajian keragaman genetik ikan tuna sirip kuning. Pemahaman yang baik tentang keragaman genetika dibutuhkan untuk merencanakan strategi konservasi tuna yang lebih baik. Penelitian ini bertujuan untuk mengetahui keragaman genetik ikan tuna sirip kuning dari dua populasi di Laut Maluku. Sebanyak 41 sampel jaringan dari tuna sirip kuning dikumpulkan dari dua populasi di Laut Maluku (Maluku Utara dan Ambon) selama ekspedisi pada bulan Februari 2013. Hasil penelitian menunjukkan bahwa keragaman genetik populasi tuna sirip kuning pada perairan Maluku Utara dan Ambon masing-masing sebesar 0,984 dan 1,00 sedangkan nilai keragaman nukleotida masingmasing bernilai 0,021 dan 0,018. Nilai keragaman genetik dan keragaman nukloetida yang tinggi didaptkan antar kedua populasi masing-masing sebesar 0,990 dan 0,020. Berdasarkan analisis filogenetik, dua populasi di Laut Maluku ini memiliki kedekatan secara genetik.

“…Exocoetids are low-tropical level species (Wu et al 2010) and are a food source for dolphinfish, tuna, and swordfish (Oxenford and Hunte 1999;Wu et al 2006). They are known as flyingfish due to their ability to glide in the air over the water using large and elongated pectoral and asymmetric caudal fins (Davenport 1994).…”

Population structure of Hirundichthys oxycephalus in the northwestern Pacific inferred from mitochondrial cytochrome oxidase I gene

et al. 2015

View full text Add to dashboard Cite

Background: Hirundichthys oxycephalus is an important flyingfish resource in eastern Taiwan and northwestern Japan. A substantial catch decline in Taiwan has caused serious concerns on stock status of the fish, prompting the government to impose a set of regulations on flyingfish egg fishery since 2008. However, the regulations were set in a precautionary manner, without considering the fundamental understanding of the population genetic structure. This study aims to investigate the population genetic structure of H. oxycephalus in the region based on mtDNA cytochrome oxidase I (COI) gene and to thus provide scientific information for sustainable management of the resource.

Microsatellite analysis of albacore tuna (Thunnus alalunga): population genetic structure in the North-East Atlantic Ocean and Mediterranean Sea

et al. 2011

Stock heterogeneity was investigated in albacore tuna (Thunnus alalunga, Bonnaterre 1788), a commercially important species in the North Atlantic Ocean and Mediterranean Sea. Twelve polymorphic microsatellite loci were examined in 581 albacore tuna from nine locations, four in the northeast Atlantic Ocean (NEA), three in the Mediterranean Sea (MED) and two in the southwestern Pacific Ocean (SWP). Maximum numbers of alleles per locus ranged from 9 to 38 (sample mean, 5.2-22.6 per locus; overall mean, 14.2 ± 0.47 SE), and observed heterozygosities per locus ranged from 0.44 to 1.00 (overall mean: 0.79 ± 0.19 SE). Significant deficits of heterozygotes were observed in 20% of tests. Multilocus F ST values were observed ranging from 0.00 to H = 0.036 and H 0 = 0.253, with a mean of H = 0.013 and H 0 = 0.079. Pairwise F ST values showed that the SWP, NEA and MED stocks were significantly distinct from one another, thus corroborating findings in previous studies based on mitochondrial DNA, nuclear DNA (other than microsatellites) and allozyme analyses. Heterogeneity was observed for the first time between samples within the Mediterranean Sea. GENELAND indicated the potential presence of three populations across the NEA and two separate populations in the Mediterranean Sea. Observed genetic structure may be related to migration patterns and timing of movements of subpopulations to the feeding grounds in either summer or autumn. We suggest that a more intensive survey be conducted throughout the entire fishing season to ratify or refute the currently accepted genetic homogeneity within the NEA albacore stock.
