Foldscopy of filter feeding action of a veliger larva.

Many benthic organism start its early life stage as a planktonic larvae. A veliger is the planktonic larva of many kinds of sea snails and freshwater snails, as well as most bivalve molluscs (clams) and tusk shells. These larvae happen to be free living and are often carried from one place to other through the water currents. They complete…

Polychaete larva feeding on organic aggregates.

Chilika is a highly productive lagoon where water contains plenty of suspended organic matter of both extrinsic and intrinsic origin. We collected water from the shore of Chilika where large amount of organic material mostly of plant origin were decomposing. Polychaetes refer such habitats where plenty of  such organic matter is available and are known…

The enthusiast participants were the 9th  and 10th class students and their teachers who…

Ultra-high imaging of benthic oligochaeta (Annelida) from seagrass medows.

Seagrass meadow support diverse flora and fauna and offer several ecosystems services such as nutrient cycling and foraging and breeding ground for many fishes and crabs.  Chilika Lagoon support a rich diversity of seagrasses and their meadows are vital in sustaining the lagoon fishery resources. Nalabana protected sanctuary inside Chilika lagoon is rich in seagrass…

High-resolution foldscopy of an actively grazing Rotifer

Shoreline of Chilika is rich in decaying submerged vegetation and foldscopy provided us an amazing view of actively grazing rotifer in samples collected from these areas. We were able to capture the live wheel movement of coronal cilia that rotifer was using to catch food. Also we noticed the internal organs and movement of jaws…

High resolution images of Spirogyra colonizing the seagrass meadows

During ground survey of seagrass meadows from southern part of Chilika Lagoon, dense growth of algae covering the seagrasses were observed. Water samples were collected on board through plankton net and mounted immediately to identify the macroalgae. Filamentous green algae: Spirogyra was identified based on their characteristics spiral pattern of chloroplast.    

Twinning of Chilika Development Authority, Odisha with Cotton University, Guwahati

Exchange of knowledge regarding use of Foldscope for analyzing the plankton samples was done under twining program with North East partner. In this context, Dr. Shamim Rahman, Scientific assistant in the Department of Zoology, Cotton University, Guwahati and his team visited Wetland Research and Training Center to gain hands on experience in using the foldscope…

First Outreach Programme at Kendriya Vidyalaya, INS Chilika

On 5th of October 2018, the first outreach programme for school children was held in Kendriya Vidyalaya, INS, Chilika on the theme “Outreach programme on seagrass biodiversity of Chilika under Foldscope”.
