Peat swamps are known to be important habitats for fish fauna that have narrow niches and restricted range. As peatland is being utilised for agriculture, biodiversity conservation plays an essential role as one of the criteria for defining sustainable agriculture. In an oil palm production landscape which is located at Tinbarap Estate in Miri, Sarawak, a total of 210.63 ha of peat swamp forest have been set aside as the Tinbarap Conservation Area (TCA) for conservation efforts. This study documents the fish fauna of Sungai Kulak which flows through the conservation area. Sampling was conducted in April 2016 and November 2016, from which a total of 106 fishes representing 13 species and seven families were recorded. In terms of the number of individuals caught, 78.30% were from the family Cyprinidae, 8.49% from Siluridae, 4.72% from Channidae, 3.77% from Osphronemidae, 1.89% from Anabantidae, 1.89% from Bagridae and 0.94% from the family Helostomatidae. The dominant species was Desmopuntius johorensis which accounted for 47.17% of the total fishes recorded. The dominance of Cyprinidae in TCA was similar to that in other peat swamp habitats. The results of our present study provide useful information on the diversity of fishes in Sungai Kulak which in the future could be valuable in conservation planning of the aquatic environment in TCA of Tinbarap Estate.

Paya gambut dikenali sebagai habitat penting bagi jenis ikan yang hanya terhad mendiami habitat-habitat tertentu. Oleh sebab pertanian juga dijalankan di tanah gambut, pemuliharaan biodiversiti memainkan peranan penting sebagai salah satu kriteria untuk menjamin pertanian lestari. Di landskap penanaman sawit yang terletak di Ladang Tinbarap di Miri, Sarawak, sejumlah 210.63 Fishes of a Conserved Peat Swamp Forest in an Oil Palm Plantation Ella Michael Dosi*, Andrew Alek Tuen**, Ivan Chiron Yaman# and Kho Lip Khoon* ha hutan paya gambut telah diwartakan sebagai Kawasan Pemuliharaan Tinbarap (TCA), untuk tujuan usaha pemuliharaan. Kajian ini bertujuan untuk mengenal pasti dan menyenaraikan spesies ikan yang terdapat di Sungai Kulak di TCA. Kerja persampelan telah dijalankan pada April 2016 dan November 2016, hasilnya sejumlah 106 ikan yang diwakili oleh 13 spesies dan tujuh famili telah direkodkan. Daripada keseluruhan individu yang direkodkan, 78.30% terdiri daripada famili Cyprinidae, 8.49% Siluridae, 4.72% Channidae, 3.77% Osphronemidae, 1.89% Anabantidae, 1.89% Bagridae dan 0.94% daripada famili Helostomatidae. Spesies dominan ialah Desmopuntius johorensis, yang mewakili 47.17% daripada jumlah ikan yang tercatat. Dominasi oleh Cyprinidae di TCA serupa dengan habitat di paya gambut lain. Hasil kajian ini memberikan maklumat tentang kepelbagaian ikan di Sungai Kulak pada masa hadapan yang dapat digunakan dalam perancangan pemuliharaan persekitaran akuatik TCA di Ladang Tinbarap.
