Examination of the holotype and three recently collected additional specimens from the Indian Ocean has revealed that Lophius triradiatus Lloyd, 1909 (now under Lophiodes) is a valid species and a senior synonym of Lophiodes infrabrunneus Smith & Radcliffe, 1912 and Lophiodes abdituspinus Ni, Wu & Li, 1990. A detailed description of the additional specimens is provided. Copyright © 2014 Magnolia Press.

Milkfish sole Aseraggodes kobensis (76.23 mm standard length) is recorded for the first time from the Western Indian Ocean. Sample was collected off the west coast of India at a depth of about 200 m during the cruise of FORV Sagar Sampada. Detailed morphometric measurements and meristic counts of the specimen are presented.

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 FST 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. © 2014 Springer Science+Business Media.

In the present study three species of mackerel, Rastrelliger present in Indian waters were taken for genetic identification using cytochrome c oxidase subunit I and 16s rRNA sequences. Accurate identification of these species is important for fishery management as its morphological characters are very similar. In this study, the sequences of COI and 16S rRNA were determined from 19 individuals of three Rastrelliger species, Rastrelliger kanagurta, Rastrelliger brachysoma and Rastrelliger faughni from Andamans and Indian mainland to study the phylogenetic relationship. The intraspecies and interspecies genetic distance ranged from 0.000 to 0.002 and 0.007 to 0.015 respectively based on 16S rRNA sequences. Using COI data analysis, the intraspecies genetic distance ranged from 0.000 to 0.012, while it varied from 0.039 to 0.086 for interspecies. The present study clearly demarcates three species of mackerel based on the mitochondrial genetic sequences and also showed a non-descriptive genetic distance of R. kanagurta from mainland and Andaman Islands. © 2014, Springer Science+Business Media Dordrecht.
