The Andaman & Nicobar Islands lie between the Andaman sea and the deeper Bay of Bengal and are the peaks of a subsurface mountain range known as the Andaman and Nicobar Ridge. The islands are situated on the great tectonic suture zone that extends all the way from the eastern Himalayas in the north to Sumatra in the east and the Lesser Sundas in the south. The geographic features of the sea-floor in this region leads one to wonder about … Read More
On 6th August 2016, while on a pelagic birdwatching trip off the coast of Chennai, we stumbled upon a huge pod of dolphins approximately about 22 kms from the coast. Initially we thought it could be a group of different species as we saw a lot of movement, and breaching dolphins jumping high up in the air at a distance. They kept moving fast with one or the other individual breaching every now and then. There were calves and adults, … Read More
To be able to observe dolphins from one’s balcony or from shore is a possibility for most of us in Mumbai. There must have been a time when Indian Ocean Humpback Dolphins (Sousa plumbea) roamed this coastal stretch in large numbers. Today they are scattered in small pockets, one of which is the bay off Raj Bhavan, Malabar Hill.
Other locations in Bombay, where these dolphins are seen is Worli, off Chowpatty in South Mumbai, Marine Drive, Sassoon Docks, and … Read More
A group of us ventured out to sea off the coast of Goa on a fishing trawler for a full-day survey of pelagic birds. These birds spend most of their lives out at sea, living a solitary life, and visit certain islands only during breeding season. We started our explorations in Goan waters in 2017, but our last two trips, on 14th and 21st October, 2018 were exciting and memorable for a completely different reason.
We usually start off by … Read More
This image of a poached Gangetic Dolphin was photographed yesterday in Bhabanathtola, Bhutni village, Malda district, West Bengal. The man was was probably carrying it from Hiranandapur towards Mathurapur.
The Forest Dept. and the police are visiting area today (30-Dec-2017). DFO Koushik Sarkar said, “We are taking the matter seriously and have also informed the police.”
In Bengal the dolphin is called the Shushuk and is just another fish-like creature for them, and is consumed locally … Read More
Skipping the Important Details — What About Mormugao’s Marine Mammals?
The coast of Goa has a rich variety of coastal and marine habitats which, besides supporting a lot of biodiversity, also sustains the tourism industry that forms the state’s economic backbone. All of this is now on the verge of destruction, with the latest developments proposed by the Mormugao Port Trust (MPT), in association with Jindal SWPL, Adani and Vedanta.
This plan, to expand the port and develop a large … Read More
Overfishing and unsustainable practices are causing fish to disappear from the world’s oceans at unprecedented rates. Pooja Rathod and Tiasa Adhya interact with fishermen in Malvan along the Maharashtra coast to learn about the impact of trawlers and the exploitation of dwindling marine resources.
“Pannas… don hazaar saahashe… paan she sattar!” The bidding calls started at Rs. 50 and reached Rs. 5,000. The monsoon month of July notwithstanding, trade was brisk inside the fish auction market in Malvan, a small … Read More
Gujarat is gifted with a beautiful 1600 km coastline, the longest in India, and a wide continental shelf, making its waters nutrient rich and diverse in marine fauna. It tops the charts in fish production, and has the highest quantities of sharks harvested in India (CMFRI, 2013). Existing catch-related data collected over the years indicated dwindling shark harvests. While at ground level, efforts to increase fish catch were intensified, it was important to study shark fisheries and local fishing trends … Read More
“Dolphin!” the driver of the fishing boat said to me excitedly, as he shook me awake from my slumber in the cabin. It was pitch dark outside. I looked at the time – it was ten past one in the morning. We were far from shore, almost eighty kilometres off the middle of the Karnataka coast, and on the crystal clear, inky blue waters of the continental shelf, just over two-hundred feet deep at our location.
Out on these seemingly … Read More
In a wide-ranging email interview with CI’s Shekar Dattatri, independent Indian ecologist, Dipani Sutaria, gives us a glimpse into her quest to study marine mammals. Based in Ahmedabad, Gujarat, Dipani is affiliated to James Cook University, Australia, from where she completed her PhD on Irrawaddy dolphins in Chilika Lagoon in eastern India. She is a member of the IUCN Cetacean Specialist Group. Her current research activities cover human-animal interactions, marine and aquatic mammals, animal behavior, urban biodiversity assessments, and … Read More
Marine organisms are frequently seen as resources that can be used or extracted seemingly limitlessly. They certainly do not come to mind as wildlife, which are in need of as much protection as terrestrial creatures, if not more. Mindless fishing or harvesting, combined with unsustainable methods, have wreaked havoc on marine systems. Seafood encompasses any sea life that is fit for consumption by humans, and additionally marine organisms are used as ‘resources’ in a variety of ways – as pets, … Read More
According to the Food and Agriculture Organization (FAO) of the United Nations, fish output in India doubled between 1990 and 2010. The populations of many marine species are threatened as a direct consequence of over-fishing to meet the increasing global demand (Myers et al., 2007). Many of these species have no local demand and are exported to China, USA, South-east asia etc. Two such species are shown in the image above – Bowmouth Guitarfish (Rhina ancylostoma) and Manta … Read More
In November 2013, our team from National Centre for Biological Sciences (NCBS) set out on a ship R/V Roger Revelle hosted by the Woods Hole Oceanographic Institution for 17 days covering around 6000km in the offshore waters of the Bay of Bengal Sea to document marine mammals. We came across 12 species of marine mammals including blue whales, killer whales and sperm whales. Apart from these we saw turtles, flying fish, butterflies, dragonflies and, unexpectedly, some terrestrial birds. The expedition … Read More
This picture was taken in May 2012 on the streets of Central Kolkata, West Bengal. I had been out doing street photography in my locality. Since I am very much concerned about conservation of nature and natural habitats, this shop caught my attention. I am a biology student and so I knew what these creatures were. These are live limulus or horseshoe crabs. Horseshoe crabs are rare marine fauna that have to be conserved. They are living fossils. A … Read More
In the 20th meeting of the Standing Committee of the NBWL held on 13 October 2010, it was discussed that linear intrusions were a serious issue and a sound policy needs to be framed consulting various experts. The Chairman requested the member of the Standing Committee from the Nature Conservation Foundation, Mysore, to prepare a background paper that could be discussed at the next meeting to move towards the formulation of a policy on linear intrusions at the national level. … Read More
