Cinque-Rutland

Summary

Cinque-Rutland is situated south of Rutland Island in the Andaman and Nicobar Islands of India. The area is bound by Rutland Island to the north and Cinque Island to the east. The area encompasses primarily shallow habitat with diverse substrates, including sand and areas of rocky substrate, rubble, and coral reef. Within this area there are: threatened species (e.g., Whitespotted Whipray Maculabatis gerrardi); and the area sustains a high diversity of sharks (33 species).

DESCRIPTION OF HABITAT

Cinque-Rutland sits in the Andaman Sea south of Rutland Island in the Andaman and Nicobar Islands of India. Rutland Island sits off southern South Andaman Island. The area is bound by Rutland Island to the north and Cinque Island to the east. It encompasses primarily shallow habitat with substrates that are diverse and include sand, and areas of rocky substrate, rubble, and coral reef.

The coastal circulation within the Andaman Sea and around the islands is primarily driven by equatorial forcing, with local winds forcing a weak sea-level signal (Chatterjee et al. 2017). The Andaman Sea has a complex oceanographic environment characterised by strong monsoonal patterns, currents, and upwelling. The climate is tropical, with two distinct seasons, the southwest monsoon and the northeast monsoon.

This Important Shark and Ray Area is benthopelagic and is delineated from inshore and surface waters (0 m) to 300 m based on the bathymetry of the area.

CRITERION A

VULNERABILITY

Thirty-three Qualifying Species considered threatened with extinction according to the IUCN Red List of Threatened Species regularly occur in the area. Threatened sharks comprise one Critically Endangered species, two Endangered species, and 10 Vulnerable species; threatened rays comprise two Critically Endangered species, 14 Endangered species, and four Vulnerable species (IUCN 2024).

CRITERION D

SUB-CRITERION D2 – DIVERSITY

Cinque-Rutland sustains a high diversity of Qualifying Species (33 species). This exceeds the regional diversity threshold for Asia (31 species).

Cinque-Rutland is one of the most important fishing grounds for benthic trawlers, gillnets, and demersal longliners operating from Junglighat, South Andaman Islands (Bineesh et al. 2020; Tyabji et al. 2020, 2022; Nashad unpubl. data 2023). Sharks and rays are a regular incidental catch of these fisheries operating in Cinque-Rutland and landed at Junglighat or Wandoor. The Qualifying Species represent the most regularly encountered species (Bineesh et al. 2020; Tyabji et al. 2020, 2022; Nashad unpubl. data 2023). This includes, for example, dedicated fish landing surveys between January 2017 and May 2018 for sharks, and October 2017 and May 2018 for rays (Tyabji et al. 2020, 2022).
