Dr Rucha Karkarey

Rucha is an Honorary Researcher at Lancaster Environment Centre. She has worked on animal behavioural responses to rapid environmental change and examines how animal behaviour can be incorporated into marine conservation. Rucha came to LEC Reefs as a Royal Society Newton International Fellow before gaining a National Geographic Explorer grant.

Research Interests

Working in the Lakshadweep archipelago (India) over the last decade, Rucha is interested in the political ecology of the conservation of coral reef fish spawning aggregations. In her more recent project as a National Geographic Explorer (2022-2024), Rucha examined the social-ecological dynamics of fish spawning aggregations in the Lakshadweep archipelago, where major fisheries transitions (pelagic-reef fish) are taking place.

Her work addressed two broad themes with an aim to inform conservation :

Understanding the ecological vulnerabilities of fish spawning aggregations by studying changes in fish behaviour along spatial, environmental and anthropogenic gradients.
Understanding change in local ecological knowledge, livelihood and nutritional dependence of coastal communities on coral reef fish.
