Financial Assistance provided to 10 Major Ports and 8 Non Major Ports for procurement of Oil Spill Response (OSR) Equipments: Shri Mansukh Mandaviya

In a reply to a question in Rajya Sabha today the Minister of State for Shipping (I/C) and Chemicals & Fertilizers, Shri Mansukh Mandaviya said that theGovernment has developed a standard operating procedure for all ports in the country to deal with oil spills and other accidents that can damage the marine ecology surrounding the…

Endangered rays may have secret nursery in Mexican waters

Credit: CC0 Public Domain The discovery of dozens of pregnant giant devil rays entangled in fishing nets along Mexico’s Gulf of California could mean the endangered species has a previously unknown birthing zone in nearby waters. That’s the conclusion of a study led by Leo Chan Gaskins, a doctoral student in marine science and conservation…

Lights on fishing nets save turtles and dolphins

Placing lights on fishing nets reduces the chances of sea turtles and dolphins being caught by accident, new research shows. LED lights along the top of floating gillnets cut accidental “bycatch” of sea turtles by more than 70%, and that of small cetaceans (including dolphins and porpoises) by more than 66%. The study, by the…

Comment on “Demographic dynamics of the smallest marine vertebrates fuel coral reef ecosystem functioning”

AbstractBrandl et al. (Reports, 21 June 2019, p. 1189) report that cryptobenthic fishes underpin coral reef ecosystem function by contributing ~60% of “consumed fish” biomass and ~20% of production. These results are artifacts of their simulation. Using their data and model, we show that cryptobenthic species contribute less than 4% to fish production, calling into…

Ocean microbes: Novel study underscores microbial individuality

A single drop of seawater can contain a wide representation of ocean microbes from around the world — revealing novel insights into the ecology, evolution and biotechnology potential of the global microbiome. A new publication in Cell reports a staggering degree of biological diversity that defies contemporary definitions of microbial species, illuminates reasons behind challenges…

MBL team images the bacterial hitchhikers on plastic trash in ocean

The structure of microbial communities colonizing microplastics collected from the North Atlantic Ocean (Vineyard Sound, Woods Hole, Mass.) This image reveals the phylogenetic affiliations of different bacterial groups. Large ellipsoid and pennate yellow cells= diatoms; long filamentous cell across center = cyanobacteria; blue= general bacteria; yellow rods = Bacteroidetes; red = Alphaproteobacteria; cyan= Rhodobacteraceae. Scale…

Animals could help humans monitor oceans

Sharks, penguins, turtles and other seagoing species could help humans monitor the oceans by transmitting oceanographic information from electronic tags. Thousands of marine animals are tagged for a variety of research and conservation purposes, but at present the information gathered isn’t widely used to track climate change and other shifts in the oceans. Instead, monitoring…

Unlocking the secrets of badger dispersal to minimize the spread of bovine TB

Zoology researchers from Trinity College Dublin, working with the Department of Agriculture, Food and The Marine (DAFM) and the National Parks and Wildlife Service (NPWS), have unlocked the secrets of dispersing badgers. Their research has major implications for implementing vaccination programmes to limit the spread of bovine tuberculosis (TB). The findings come at an opportune…
