Wild-harvested Marphysa madrasi for biosecure aquaculture: nutritional profiling, pathogen screening, and phylogenetic assessment

Abstract Polychaetes are widely used as high-value aquaculture feed, yet India continues to depend heavily on imported species despite the availability of locally abundant taxa. However, the nutritional potential, biosafety, and taxonomic clarity of indigenous polychaetes remain...

Influence of chlorophyll-a and environmental drivers on fish landings along the west coast of India

Fish landings along the west coast of India account for ~ 65% of the country’s total marine catch, with regional contrasts. This study investigated how fish landings relate to chlorophyll-a and key environmental drivers including sea surface temperature (SST), wind velocity, and...

Distribution of surface layer temperature inversion in the North Indian Ocean and associated acoustic propagation characteristics

Surface Layer Temperature Inversion (SLTI), a warm layer between the surface and subsurface colder waters, is a significant oceanographic feature that has a profound impact on the oceanic acoustic propagation. Strong inversions are observed in northern BoB and in the South Easter...
