Polychaetes obtained from the Bon Accord Lagoon Tobago, Trinidad and Tobago

Study Extent

The Bon Accord Lagoon is located on the southwest coast of Tobago, which is located 32 km northeast of Trinidad, in the southeast Caribbean.

Sampling

Benthic macrofauna were collected among seagrass beds within the Bon Accord Lagoon, Tobago during two sampling periods, the dry and wet seasons of 2018 (March and September, respectively) using a handheld PVC corer. The National Geography in Shore Areas (NaGISA) protocol for sampling seagrass infauna was used which involved immersing a 15 cm diameter corer to a depth of 10 cm and using a rubber bung at the top of the device to create a vacuum.

Method steps

1. Core samples were sieved in the field using a 0.5 mm mesh screen. Samples were stained with Rose Bengal and preserved with a 10% formalin seawater mixture. The benthic organisms studied were polychaetes, which were sorted and identified to the lowest possible taxonomic level using the key: The Polychaete worms. Accepted taxa were checked against the World Register of Marine Species www.marinespecies.org
