The present study was undertaken to determine the effects of polyunsaturated fatty acids (PUFAs) on enhanced maturation, spawning, embryonic and larval development endangered Gangetic Mystus (Mystus cavasius). Fishes were collected from Brahmaputra River, Mymensingh, Bangladesh stocked in cisterns. Treated group provided supplemental diet enriched with 1% squid extracted lipids as a source PUFA...

The tropical and subtropical floodplain lakes are hypothesized as one of the globally interesting rotifer rich ecosystems. Our study indicating biodiverse Rotifera ten ‘slightly acidic to circum-neutral, moderately hard-water de-mineralized’ (beels) Majuli River Island Brahmaputra river basin northeast India mendorses this hypothesis. Total richness, richness important families community simila...

Managing transboundary river basins proves a challenge for China when encountering disagreements with its neighbors that experience different political and social conditions. This paper analyzes what happens characterizes water as security issue, examining China’s fluid securitization practices, where changes can be identified indicating the Chinese government values various concerns differentl...

Deltas are discrete shoreline protuberances formed where rivers enter oceans, semi-enclosed seas, lakes or lagoons and supply sediment more rapidly than it can be redistributed by basinal processes. Generally, deltas are served by well-defined drainage systems which culminate in a trunk stream and supply sediment to a restricted area of the shoreline, thus resulting in the formation of a depoce...

The Himalaya and adjacent Tibetan Plateau are the source of several major Asian rivers supporting a large, diverse ecosystem and a population of more than 1 billion people [Ives and Messerli, 1989; Barnett et al., 2005]. Large rivers such as the Indus, Sutlej, Ganges, Arun, and Brahmaputra/Tsangpo draining the southern Tibetan Plateau and the Himalaya are essential for agriculture and energy ge...

levels, and fl ow variability from orbital sensors have the potential to directly measure the runoff component of the Earth’s hydrologic cycle [Birkett et al.,2002; Brakenridge et al., 1998; Sippel et al.,1994, 1998; Townsend, 2001]. A remote-sensing-based measurement strategy for rivers and streams is emerging: Surface water data can be collected, their accuracy evaluated, and the results diss...

International Ocean Discovery Program (IODP) Expedition 353 (29 November 2014–29 January 2015) drilled six sites in the Bay of Bengal, recovering 4280 m of sediments during 32.9 days of on-site drilling. Recovery averaged 97%, including coring with the advanced piston corer, half-length advanced piston corer, and extended core barrel systems. The primary objective of Expedition 353 is to recons...

Circulation of saline water is important for maintaining quality in the Ganges-Brahmaputra-Meghna (GBM) delta because its vulnerability to threat climate change. We applied a numerical model examine volume and salt transports within GBM delta, Bangladesh. To understand components intrusion driven by tidal subtidal (residual) transports, we selected 19 cross-sections represent complex circulatio...
