Blood cockle, Anadara cornea locally known as ‘Kerang Bulu’ is one of the bivalves in Setiu Wetlands, Terengganu. They were retrieved from the wild to be traded by the coastal communities for more than 20 years. This bivalve plays role in contributing as income resources for the local community caused by the continuous harvesting from their habitat. There is a lack of research in determining the population density and size of A. cornea in Setiu Wetlands Therefore, this study aims to determine the population density and size of A. cornea in Setiu Wetlands during Northeast monsoon season from November 2015 to March 2016 by using line transect method. A total of 1,506 individuals of A. cornea were collected with the lowest population density recorded in December 2015 (2.83 ± 0.64 individuals /m2 ). The highest was in March 2016 (4.37 ± 0.97 individuals /m2 ). Mean size of A. cornea recorded was 23.92 mm shell length, 20.69 mm height and 16.39 mm width. The largest A. cornea was recorded in November with shell length, height and width of 56.16 mm, 45.13 mm and 39.77 mm, respectively. This report on the population density and size of A. cornea during Northeast monsoon season in Setiu Wetlands could serves as a reference by local communities and authorities for sustainable management
