摘要：A questionnaire survey and field investigation in the shrimp farms were conducted in the coastal regions of Villupuram and Cuddalore district in the East Coast of South India from October to November 2012. A total of 16 farms were interrogated to identify and quantify the number of birds considered to be a threat to shrimp farming. Tiger shrimps (Penaeusmonodon) and Vannamei (Penaeusvannamei) were the two widely cultivated species in this region. A total of 19 species of birds were observed, that includes, cormorants, coots, egrets, kingfishers and kites. Among the different size class of birds 58%, 32%, and 10% were small, medium and large birds, respectively. In foraging mode of birds 78% were active foragers caused highest damage in the farm. Scavenging birds and mud probers constituted 11% each of the total bird species. Farmers were more concerned about the disease transmission by mechanical or fecal contamination rather than predation. Based on the present findings management measures were suggested.
