The mitochondrial control region has been the first choice for examining the population structure but hypervariability and homoplasy have reduced its suitability. We analysed eight populations using control region for examining the population structure of Hilsa. Although the control region analysis revealed broad structuring between the Arabian Sea and Bay of Bengal (F ST  0.0441, p < 0.001) it...

to18 th Febrauary 2013 in the coastal waters of the Bay of Bengal. Marked variations observed with respect to almost all nutrients determined. The detectable ranges of ammonium, nitrite, nitrate, phosphate and silicate were 0.026-23.52, 0.018-0.41, 0.026-4.46, 0.18-7 and 0.37-20.31μM respectively. The higher concentrations of nutrients were observed on 15 th February 2013. Among these five nutr...

This paper describes wave directional spreading in shallow water. Waves were measured for a period of 2 months using the Datawell directional waverider buoy at 15 m water depth on the east coast of India in the Bay of Bengal. The study also showed that in shallow water wave directional spreading was narrowest at peak frequency and widened towards lower and higher frequencies. The wind direction...

The aim of the present study was to determine the presence of p,p’-DDT and its metabolites (p,p’DDE and p,p’-DDD) and ã-HCH and PCBs in the muscle of gray mullet, Mugil cephalus collected from Cuddalore coast of Bay of Bengal during the period from June 2009 to January 2010. Polychlorinated hydrocarbons are convenient indicators of environmental pollution. The analyses were carried out using th...

Ex-Surgeon-Superintendent of the Emigrant-ship " Canada Jankie, a Hindoo girl, aged 18 years, was admitted on the 9th July with fracture of both bones of the right leg and a lacerated wound at the posterior part of the ankle.' The accident was caused by a fall from the top of the ladder on to the 'tween deck-?a height of about 12 feet?whilst going down below during a heavy squall in the Bay of ...

A new species of short brown unpatterned moray eel of the genus Gymnothorax, Gymnothorax mishrai sp. nov. is described from a specimen of 324 mm total length, collected from the Bay of Bengal. The species is distinguished by having the dorsal-fin origin before gill opening, jaw pores with brown rim, two branchial pores, total vertebrae 134 (MVF: 9-59-134), three median intermaxillary teeth, uni...

The Indian Ocean (Figure 1) comprises 20% of the World’s surface water, has an austral to tropical temperature gradient, is bounded to the east by the African continent, to the north by the Asian land mass (which includes semi-enclosed seas the Red Sea, Arabian Gulf, Gulf of Thailand and Bay of Bengal), and to the West by SE Asia (Thailand, Malaysia, Indonesia, Timor L’Este and Australia). The ...
