Neobythites stefanovi is recorded for the first time from Indian waters in the Gulf of Mannar. Two specimens were landed as by-catch in trawl gear at Tuticorin fisheries harbour, south-east coast of India, in March 2010. This is also the first record of the species outside the Red Sea, Gulf of Oman and Gulf of Aden, in the western Indian Ocean. © Marine Biological Association of the United Kingdom 2013. Source

A new record on the occurrence of Neobythites multistriatus which hitherto had not been recorded from the Bay of Bengal is reported. Two specimens measuring 160 and 180 mm standard length were collected from the landings of a deep-sea trawler by-catch at depths of 200-250 m off the Tuticorin coast in the Gulf of Mannar (part of the Bay of Bengal) during March 2010. This is the first record of Neobythites multistriatus from the Bay of Bengal. The specimen is described and figured. © Marine Biological Association of the United Kingdom 2013. Source

The olive ridley sea turtle Lepidochelys olivacea is known for its unusual behaviour of locally nesting en masse in the eastern Pacific and the east coast of India, leading to difficulties in quantifying population size. In the present study we estimate nesting population sizes in the state of Orissa, taking average egg laying or oviposition duration (OD) into account. We observed 182 and 263 nesting turtles during mass nesting events of 2009 and 2010 to estimate ODs of 19.8±5.8 and 17.2±5.9 minutes, respectively. Clutch size averaged 123.1±10.5 for 2009 and 124.3±18.6 for 2010, which is 10 to 20% more than the global clutch size of 100-110 eggs, and appears to have resulted in a longer OD than previously assumed. Using the average OD from this study, 172,407±7509 and 134,478±6204 turtles were estimated to have nested during 2009 and 2010 respectively, contrasting the 200,000-250,000 turtles reported by the Forest Department. Our results suggest that a minimum of 150 egg laying turtles across each night of the mass nesting period is required to be observed for an accurate quantification of OD. Source

Two specimens of Valenciennea helsdingenii (Bleeker, 1858) were collected off Punnakayal coast, from Gulf of Mannar, southeast coast of India in November 2012. The morphometric and meristic characters of the recorded specimens are described and discussed. This is the first record of the species from the Indian waters that is a range extension of its known range within the Indian Ocean. © K. Kannan et al. Source
