This study was conducted to evaluate the species diversity and feeding habits of fish population in the Pengkalan Gawi – Pulau Dula section of Tasik Kenyir Terengganu. Samples were collected monthly from February 2008 to January 2009 (12 months) at three sampling stations designated as Station A (Pulau Dula), Station B (Sungai Ikan) and Station C (Pulau Pupi). Fish sample were collected using gill nets measures 100 m long, 3 m deep and having a stretch mesh size of 6.35 cm (2.5 inches). A total of 274 individuals fish comprising 13 species from 5 families were collected during the study period. The mean values for the Shannon-Weaver index, Pielou Evenness index and Margalef Richness index were 1.41±0.23, 0.81±0.13, 3.53±0.62 respectively.

Six most dominant species namely Barbodes schwanenfeldii, Notopterus sp., Hampala macrolepidota, Hemibagrus nemurus, Channa micropeltes and Pristolepis faciatus were selected for the study on the stomach contents. Among the wide and variety prey consumed, Aquatic insect was the most important food item fed by the fish species in this ecosystem. The Aquatic insect food item was abundant in the stomach of H. nemurus thus it was categorized as insectivore fish species. Four other species comprising B. schwanenfeldii, Notopterus sp., H macrolepidota and P. faciatus consumed on balance dietary component mostly Aquatic insect, Fish food item, Plant materials and Phytoplankton. The stomach content of C. micropeltes was found with high percentage of Fish food item and it was classified as piscivore fish species with the highest Trophic Level value of 3.56±0.63.

In terms of spatial distribution, Shannon-Weaver index value in Pulau Dula was the lowest when compared to the other stations. This station was inhabited by 9 species with 72 individuals fish, while Sungai Ikan was inhabited by 11 species with 128 individuals and Pulau Pupi was inhabited by 7 species with 74 individuals fish. All of the six most dominant species were present at each station and most of them were found in abundance specifically in one station, indicated that they were limited to one particular habitat. Temporally, the three most dominant species included B. schwanenfeldii, Notopterus sp. and H. macrolepidota were present in the monthly samples throughout the study period.

The results of this study indicated that most of the species found were similarly reported in other studies in Tasik Kenyir. It is hoped that the results will be useful in contributing towards management of the lake in a sustainable manner for future generations.

Kajian ini dijalankan untuk menilai kepelbagaian spesis dan tabiat pemakanan bagi populasi ikan di Seksen Pengkalan Gawi – Pulau Dula di Tasik Kenyir, Terengganu. Sampel ikan dikumpul pada setiap bulan bermula dari bulan Februari 2008 sehingga Januari 2009 (12 bulan) di tiga stesen penyampelan yang dinamakan sebagai Stesen A (Pulau Dula), Stesen B (Sungai Ikan) dan Stesen C (Pulau Pupi). Sampel ikan ini dikumpul dengan menggunakan pukat insang berukuran 100 m panjang, 3 m labuh dan saiz mata pukat berukuran 6.35 cm (2.5 inci). Sebanyak 274 individu ikan merangkumi 13 spesies dari 5 famili telah dikumpulkan sepanjang kajian ini dijalankan. Nilai min bagi indeks Shannon-Weaver, indeks Pielou Evenness dan indeks Margalef Richness adalah masing-masing dengan nilai 1.41±0.23, 0.81±0.13 dan 3.53±0.62.

Enam spesis paling dominan seperti Barbodes schwanenfeldii, Notopterus sp., Hampala macrolepidota, Hemibagrus nemurus, Channa micropeltes dan Pristolepis faciatus dipilih bagi mangkaji kandungan isi perut ikan. Diantara pelbagai jenis mangsa yang dimakan, Serangga akuatik merupakan jenis makanan yang paling penting yang dimakan oleh ikan di dalam ekosistem ini. Makanan Serangga akuatik mempunyai kelimpahan tertinggi di dalam kandungan isi perut H. nemurus justeru ia dikategorikan sebagai spesis ikan insektivor. Empat spesis lain merangkumi B. schwanenfeldii, Notopterus sp., H macrolepidota dan P. faciatus mengambil komponen pemakanan yang seimbang dimana kebanyakannya adalah terdiri daripada Serangga akuatik, Makanan jenis ikan, Kandungan bahan tumbuhan dan Fitoplankton. Kandungan isi perut C. micropeltes pula didapati mempunyai peratusan tertinggi bagi Makanan jenis ikan dan ianya dikelaskan sebagai spesis ikan pisivor dengan nilai Trophic Level tertinggi iaitu 3.56±0.63.

Dari segi taburan mengikut ruang, nilai indeks Shannon-Weaver di Pulau Dula merupakan yang terendah apabila dibandingkan dengan stesen-stesen yang lain. Stesen ini didiami oleh 9 spesis dengan 72 individu, manakala Sungai Ikan didiami oleh 11 spesis dengan 128 individu dan Pulau Pupi didiami oleh 7 spesis dengan 74 individu ikan. Kesemua enam spesis ikan dominan hadir di setiap stesen dan kebanyakan mereka ditemui tertumpu hanya di satu stesen dengan kelimpahan yang tinggi, ini menggambarkan bahawa mereka adalah terhad di dalam satu habitat tertentu sahaja. Dari segi masa pula, tiga spesis paling dominan termasuk B. schwanenfeldii, Notopterus sp. dan H. macrolepidota hadir di dalam sampel bulanan sepanjang tempoh kajian dijalankan. 

Keputusan kajian ini menunjukkan bahawa kebanyakan spesis yang ditemui turut juga dilaporkan didalam kajian lain di Tasik Kenyir. Diharap, agar keputusan ini berguna dalam menyumbang kepada pengurusan yang mampan di Tasik Kenyir untuk generasi yang akan datang.
