Freshwater turtles are among the least studied faunas in the Andaman and Nicobar Islands, India. Here, we report the presence of freshwater turtles (Cuora amboinensis) from Car Nicobar, a small remote island in the Nicobar archipelago comprising the Andaman and Nicobar Islands. Semi-structured interviews were conducted with the people belonging to Nicobarese tribes (n = 233) to gather their local ecological knowledge as supportive information to obtain a better understanding of the status of turtles in Car Nicobar. Most interviewees (90%) opined that freshwater turtles are found to be rare or very rare on the Island. All the respondents (100%) expressed willingness to contribute to future conservation projects. Community-level awareness emerged as a prominent issue for future conservation using the Garrett ranking method. A stream network map was prepared using the digital elevation model to visualize streams and potential habitats of turtles. This report on the freshwater turtles is essential from an ecological perspective since information is scarce on the freshwater turtles in Car Nicobar. This study emphasizes the importance of the engagement of stakeholders in conservation projects and recommends providing adequate attention to the conservation and protection of freshwater turtle diversity in Car Nicobar.

“…Studies on the tropical storm's impact on reefs in Ritchie's Archipelago, Andaman, revealed that reefs suffered severe damage following the storm's passage. Also, high waves and increased sediment load by surface run-off caused significant damage to reefs in shallow and deeper regions (Krishnan et al, 2013).…”

Extreme weather events such as tropical cyclones strongly influence marine fishery landings along the Indian coast. This paper assessed tropical cyclone Ockhi's impacts on the marine fishery resource assemblages along the Kerala and Tamil Nadu coasts. Apart from this, variation in environmental variables during the cyclone and their association with fishery was evaluated. The catch composition before, during, and after the Ockhi was determined using the SIMPER (Similarity Percentages) analysis. The species dissimilarity was high during and after the cyclone compared to the pre-cyclone data. The main environmental variations noticed during Ockhi were the decline in sea surface temperature, a hike in chlorophyll, salinity, and upwelling. Moreover, current speed and direction variations were observed during the cyclone month, and it might have badly affected fish recruitment. The study revealed the exponential changes in fish abundance during the cyclone and showed a sign of recovery in the post-cyclone period. This indicates that ecosystem changes due to such extreme events are not long-lasting, and the beneficial ecological changes in the habitats were helpful for the higher fish landings in the post-cyclone period.

“…In case of ANI, marine ecosystems that support fisheries such as coral reefs, mangroves and sea grass beds were seriously impacted by events such as increased sea surface temperature, tsunamis, earthquake, cyclones, storm surges etc. (Roy and Krishnan 2005;Krishnan et al 2011Krishnan et al , 2012Sachithanandam et al 2014;Yuvaraj et al 2015;Majumdar et al 2018). Coral reefs, mangroves and sea grass beds harbour major fish diversity of ANI (Rajan et al 2013) hence any impact on these ecosystem can adversely affect the fish diversity of these ecosystems ultimately affecting fishermen who are dependent on these ecosystems for livelihood and income generation.…”

Fisheries governance in the tropical archipelago of Andaman and Nicobar – opinions and strategies for sustainable management

Globally, marine fisheries sector provides livelihood, food security and employment to the fishers engaged in subsistence, artisanal and industrial fishing activities. The dependency on marine fish supplies keeps rising globally leading to intense competition, fishery conflicts and unsustainable fishing practices which threatens the sustainability and leading to the depletion of marine fishery resources. Andaman and Nicobar Islands (ANI) in India is a tropical archipelago cited as an example where marine fishery resources were considered to be highly underutilized vis-a-vis the harvestable potential. Developmental plans often envisage the enormous scope to harness the oceanic fishery resources however, the overriding issues which affect the sustainable fishery management were least understood or addressed. Offshore fisheries were trade and economy based whereas small scale fisheries are livelihood and food security-based, operating with small to medium scale commercial prospects. Radical management approaches in artisanal and industrial fisheries is essential to foster community resilience and sustainable fishery management. The emerging body of evidence suggests the critical need to reliably estimate the fish catches and population dynamics for sustainable fisheries management. Comprehensive opinions on prevailing issues, complexities in governance, challenges faced and the management strategies that need to be adopted were discussed to ensure the robust governance and sustainability of marine fisheries sector.
