![]() Manakala lain-lain superfamili hanya diwakili satu spesies sahaja. Superfamili Tonnidae diwakili 7 spesies, diikuti Muricoidea (5 spesies), Cypraeoidea (4 spesies), Buccinoidea dan Conoidea (2 spesies). Sebanyak 23 spesies gastropod telah dikenalpasti sepanjang dua bulan kajian yang bermula dari 16 Ogos hingga 6 Oktober 2015 di mana ia terdiri daripada 8 superfamili, 15 famili dan 20 genus. Operasi menunda dijalankan di kawasan melebihi 12 batu nautika dari pesisir pantai dan kawasan stesen dibahagi kepada tiga strata kedalaman iaitu, I) 20–50 m, II) 50–100 m dan III) 100–200 m. Operasi menunda menggunakan pukat tunda dengan saiz regangan 38 mm pada penghujung pukat. Sampel gastropod dikumpul dari stesen yang terpilih di ZEE Sarawak. Kajian ini menyediakan senarai gastropod marin yang pertama dari perairan Zon Ekonomi Eksklusif (ZEE) Sarawak. The information on gastropod distributions at different depth strata in the Sarawak EEZ could be useful in updating the Malaysian species diversity database. ![]() In addition, 9, 13 and 4 species of gastropods were found in strata I, II and III, respectively. Only 3 species were obtained in 2 depth strata, namely Melo melo, Murex aduncospinosus and Tonna galea. Other superfamilies were represented by a single species. Superfamily Tonnoidea was represented by 7 species, followed by Muricoidea (5 species), Cypraeoidea (4 species), and Buccinoidea and Conoidea (both with 2 species). A total of 23 gastropod species were identified during the two-month sampling period from 16 August until 6 October 2015, representing 8 superfamilies, 15 families and 20 genera. The trawling operations were conducted more than 12 nautical miles from the coast, and the area was divided into three depth strata: I) 20-50 m, II) 50-100 m and III) 100-200 m. Gastropod samples were collected from selected stations in the Sarawak EEZ using an otter trawl net with a stretched mesh size of 38 mm at the cod end. These two communities involve mainly in business, private and civil service sectors.This study provides the first marine gastropod checklist from the Sarawak Exclusive Economic Zone (EEZ). The Chinese live around the Kapit, Song and Belaga towns and four Malay settlements can be found in the suburbs. Most Iban and Orang Ulu work in logging camps and are subsistence farmers practising shifting cultivation. The area is home as well to nomadic Penan community, many of whom are still hunter-gatherers. Other smaller communities are Kajang (include Punan or Punan Bah, Sekapan, Kejaman, Lahanan, Tanjong) and Ukit. Two main groups of Orang Ulu in the Kapit Division are the Kayan and the Kenyah. The Orang Ulu refers to a number of smaller ethnic groups that settle upriver mainly in Belaga District and the term ‘Orang Ulu’ literally means ‘upriver’ people. There are 534 longhouses in the division, most of them located along the major rivers.Ībout 90% of the Iban inhabits the Rejang up to, and a little beyond, Kapit as well as the lower reaches of the Baleh and its tributaries. The Iban are the largest ethnic group in Kapit, at 67.4%. About 88.4% of the population settles in rural areas and 57.4% resides in Kapit District. Population by district is Kapit: 56,709, Song: 19,236 and Belaga: 22,896 meanwhile population density is 2.5 (person per sq km). In 2000 census, Kapit Division recorded a total population of 98,841 people which constituted only 4.9% of the total population in Sarawak (2,009,893). Belaga is located in the upper Rejang Basin, at the confluence of the Belaga and Balui Rivers and is about 281km from Sibu town (155km from Kapit). These rivers are the main means of transportation in the division.įrom Sibu, Song is 85km away and Kapit 126km. ![]() The mighty Rejang River (at 551 km), the longest river in Malaysia, and its main upper tributaries, Batang Baleh, Batang Katibas, Batang Balui and Sungai Belaga flow through the division. Undulating low hills are also found in areas between Bakun Resettlement Scheme in Sungai Asap and Tabau. Low lying plains are found in Sungai Tunoh, Sungai Melinau, Sungai Tiau, Sungai Mujong, Nanga Merit and Nanga Lajan areas. Kapit Division is a mountainous region mostly (80%) covered by dense primary forests. It is also the largest division in Sarawak with an area of 38,934 sq km, almost one-third of the total land area of Sarawak (124,450 sq km). It is bordered by Kalimantan, Indonesia at the south and east, Miri and Bintulu Divisions at the north and Sibu Division at the west. Kapit Division is located in the central part of Borneo. Kapit Division was promulgated as the Seventh Division on 2nd April 1973. The State of Sarawak is presently divided into eleven administrative divisions.
