The golden anchovy, Coilia dussumieri, though possessing discontinuous distribution along northeast and northwest coasts of India, it is being managed as unit stock for fishery assessment purposes. By considering the need for stock specific management of the species, mitochondrial ATP synthase 6 and 8 (ATPase 6/8) genes were analyzed for delineating genetic stock structure of the species. Sequence analysis revealed a total of 34 haplotypes across four populations from both the east and west coasts of India. Haplotype diversity (h) was found in the range of 0.7421–0.9368. Similarly, nucleotide diversity (π) varied from 0.0012 to 0.0025. AMOVA results indicated a high total variance of 72.66 % between east and west coast populations and less (1.34 %) among populations within the respective coast. Phylogenetic tree constructed using pair wise FST also indicated the genetic divergence of populations of east and west coasts of India. The findings of the present study will be helpful in developing stock specific management measures for conservation and sustainable utilization of the species.  相似文献

A new species of the ophichthid eel of the family Ophichthidae is described based on five specimens collected from the Mudasalodai fish landing center, off Cuddalore coast, southeast coast of India, Bay of Bengal. Ophichthus naevius sp. nov. is distinguished from its congeners by having a unique color pattern: dorsal body with numerous dense dark spots or patches, ventral body pale yellowish green, dorsal-fin origin just before pectoral-fin tip, vertebral formula: 12–14/52–53/134–138, and teeth on jaw uniserial and pointed. The study also reports the range extension and molecular evidence of Ophichthus chilkensis from South India. Molecular analyses were performed for both species, and their phylogenetic relationship suggests that the new species exhibits 10.2% genetic divergence with its congener Ophichthus sangjuensis, followed by Ophichthus brevicaudatus (10.4%), and Ophichthus sp. 1 (11.8%) also forms the closest clade in both Bayesian inference and maximum likelihood (ML) tree. Similarly, according to the topology of the ML tree, the species O. chilkensis forms a clade with Ophichthus sp. 5, Ophichthus remiger, Ophichthus frontalis, Ophichthus sp. 6, and Ophichthus rex, suggesting that it would be the genetically closest congener.  相似文献

Coilia dussumieri (Valenciennes, 1848) commonly called as golden anchovy, constitutes a considerable fishery in the northern part of both the west and east coasts of India. Despite its clear-cut geographic isolation, the species is treated as a unit stock for fishery management purposes. We evaluated 32 microsatellite primer pairs from three closely related species (resource species) belonging to the family Engraulidae through cross-species amplification in C. dussumieri. Successful cross-priming was obtained with 10 loci, which were sequenced for confirmation of repeats. Loci were tested for delineating the genetic stock structure of four populations of C. dussumieri from both the coasts of India. The number of alleles per locus ranged from 8 to 18, with a mean of 12.3. Results of pairwise F ST indicated genetic stock structuring between the east and west coast populations of India and also validated the utilization of identified microsatellite markers in population genetic structure analysis.  相似文献
