Scolopsis igcarensis, a new species of monocle bream (family Nemipteridae) from the coastal waters of southern India and Sri Lanka is described. The species is distinguished from other species of the genus Scolopsis by a combination of the following characters: scales on top of head reaching forward to between anterior nostril and snout tip; lower margin of eye below the line from snout tip to upper pectoral fin base; a bony ridge below eye; a white band from behind eye to level of end of dorsal fin base.

The composition, species richness and diversity of a coastal fish assemblage from the Kalpakkam coast of south-east India are described along with temporal distribution patterns related to seasonal fluctuations in dissolved oxygen, salinity, pH, chlorophyll-a, phytoplankton and zooplankton species richness and density. A total of 244 fish species belonging to 21 orders, 87 families and 163 genera were recorded. The fish assemblage was dominated by reef-associated species, followed by demersal species. The majority of the species (63%) are widely distributed in the western Indo-Pacific as well as in the central Indo-Pacific. Jaccard's coefficient analysis showed three distinct seasonal patterns of fish occurrence: pre-monsoon (PrM), monsoon (M) and post-monsoon (PoM). The maximum number of species was during the PrM period, followed by the PoM and M periods. Species occurrence analysis showed Sardinella longiceps to be dominant during PrM and M periods, Leiognathus dussumieri during the M period and Secutor insidiator and Secutor ruconius during the M and PoM periods. Canonical correspondence analysis indicated that salinity and rainfall were the two most influential environmental factors strongly correlated with temporal variation in the fish assemblage. The physico-chemical conditions, in combination with factors such as greater food availability and shelter, might control the seasonal local distribution of the ichthyofauna in these Indian coastal waters. © 2014 The Fisheries Society of the British Isles.

The Indo-West Pacific species, Neomerinthe erostris (Alcock 1896), originally described as Scorpaena erostris, is rede-scribed as a senior synonym of Scorpaena gibbifrons Fowler 1938, N. rotunda Chen 1981, and N. bathyperimensis Zajonz & Klausewitz 2002. Although the latter three nominal species have been regarded as valid species and N. erostris has not been reported since 1898, examinations of type specimens of the four nominal species revealed that they represent a single species. A lectotype of Scorpaena erostris is herein designated. Neomerinthe erostris is characterized by having a distinct longitudinal ridge on the lateral surface of the maxilla and a strongly rounded dorsal profile of the head. Copyright © 2015 Magnolia Press.

A specimen of garden eel, Heteroconger tomberua Castle et Randall, 1999, was collected from the traveling water screen of sea water cooling system of the Madras Atomic Power Station (MAPS), Kalpakkam located along the east coast of India. Previously, H. tomberua was recorded in Fiji, Pacific Ocean. The presently reported record greatly extends the fish range to the Indian Ocean and constitutes a new addition to the ichthy-ofauna of India. The described specimen of H. tomberua, with its total length 55.9 cm, seems to be the largest ever found. Source

A specimen of bigscale jawfish, Opistognathus macrolepis (Perciformes: Opistognathidae) was collected from the travelling water screen of Madras Atomic Power Station pump house, located at Kalpakkam, south-east coast of India. Opistognathus macrolepis was previously known only from central west Pacific, from the Gulfs of Thailand and Carpentaria, Australia. The present study reports the first record of its occurrence in the Indian Ocean from the east coast of India and constitutes a new addition to the Indian coastal ichthyofauna. © Marine Biological Association of the United Kingdom 2013.
