Keanekaragaman Burung Pantai dan Potensi Makanan di Kawasan Pantai Muara Indah Kecamatan Pantai Labu Kabupaten Deli Serdang Provinsi Sumatera Utara

Abstract

Muara Indah Beach is one of the beaches that have been established as an important area for birds. The study was conducted in February - March 2013 in Muara Indah Beach, Denai Kuala village, Pantai Labu district, Deli Serdang Regency of North Sumatra province and continued in October - November 2013 was performed biomass measurements in the Laboratory of Basic Chemical LIDA. This study aimed to determine the types of shorebirds, waterbirds foods and biomass macrozoobenthic at Muara Indah Beach Pantai Labu District Deli Serdang Regency of North Sumatera province. Research methods used in compiling data on birds was purposive method and the method count concentration obtained 19 types of shorebirds (2 families: Charadriidae and Scolopacidae). At the intake pipe paralon macrozoobenthic using methods that allegedly recovered 25 of the food shorebirds (Bivalves, Crustacea, Echinoidea, Gastropoda, Polychaeta and Phascolosomatidea). Distribution macrozoobenthic was taken to a depth of 30cm and is divided into six strata (5, 10, 15, 20, 25 and 30cm), the most widely macrozoobenthic found at depths of 10 and 15cm. Macrozoobenthic biomass calculations aimed to determine the average density calculation, dissemination and importance of shorebirds food. Based on the calculation result obtained the highest biomass from Tellina timorensis of 92,48 gram/m-3 .
