Telah dilakukan penelitian tentang struktur komunitas ikan dan upaya pengelolaannya di Danau Teluk Kota Jambi pada bulan Agustus sampai September 2012. Penelitian ini bertujuan untuk mengetahui komposisi, kelimpahan, keragaman, kemerataan, dominansi spesies ikan dan kualitas perairan pada musim kemarau serta pengetahuan lokal masyarakat dalam upaya pengelolaan perikanan di perairan Danau Teluk Kota Jambi. Pengambilan sampel ikan dan parameter abiotik dilakukan pada tiga titik stasiun yaitu bagian danau di sekitar inlet, bagian danau di sekitar pemukiman penduduk dan bagian danau yang masih alami. Pengambilan sampel ikan menggunakan alat tangkul (lift net) dan jala (cash net) dilakukan pada pukul 6.00−9.00 pagi, alat pukat (gill net) dan lukah (tubular trap) pada pukul 5.00 sore sampai 5.00 pagi, setiap 2 hari sekali dengan frekuensi setiap alat tangkap sebanyak 16 kali. Data mengenai upaya pengelolaan perikanan di Danau Teluk Kota Jambi didapat dengan cara melakukan wawancara dan pengisian kuesioner pada masyarakat nelayan yang bermukim di sekitar perairan Danau Teluk yang meliputi Kelurahan Tanjung Raden, Tanjung Pasir, Olak Kemang dan Ulu Gedong. Hasil yang diperoleh berdasarkan parameter abiotik menunjukkan kualitas perairan Danau Teluk masih mendukung untuk kehidupan ikan. Jumlah spesies ikan yang ditemukan sebanyak 55 spesies dari 19 famili dengan total individu 4788 ekor. Barbonymus schwanenfeldii memiliki jumlah komposisi spesies tertinggi sebesar 18,9% dan kelimpahan 290,33 individu/stasiun. Indeks keanekaragaman masuk kategori sedang (H'=2,622–2,722), indeks kemerataan masuk kriteria cukup merata (E=0,670–0,693) dan tidak terdapat dominansi spesies (D=0,105–0,126). Kegiatan perikanan tangkap di Danau Teluk dilakukan secara tradisional dengan intensitas penangkapan setiap hari tanpa melakukan upaya pengelolaan terhadap ikan hasil tangkapan agar lebih bernilai ekonomis. Masyarakat nelayan pada umumnya tidak mengetahui istilah konservasi sumberdaya ikan, sehingga kegiatan penangkapan ikan terus dilakukan tanpa melakukan upaya pelestarian dan perlindungan terhadap spesies ikan yang sudah jarang ditemui. Sementara kegiatan budidaya ikan dalam Keramba Jaring.
Research on fish community structure and management efforts in Danau Teluk, Jambi were conducted from August to September 2012. The objective of this study is to determine the composition, abundance, diversity, evenness, dominance of species of fish and water quality in the dry season as well as local knowledge of the community in efforts to manage fisheries in the waters of Danau Teluk, Jambi. Fish sampling and water quality parameters were conducted at three points of stasiun around the lake inlet section, part of the lake around settlements and unspoiled part of the lake. Sampling of fish using tools tangkul (lift net) and jala (cash net) were conducted at 6:00 to 9:00 am, and pukat (gill net) and lukah (tubular trap) were at 5:00 pm until 5:00 am, every 2 days with the frequency of 16 times. Data on fisheries management efforts in Danau Teluk, Jambi were obtained by conducting interviews and questionnaires on fishing communities living around the lake waters, includes the village of Tanjung Raden, Tanjung Pasir, Olak Kemang and Ulu Gedong.The results obtained by physical environmental parameters indicate the quality of the waters of Danau Teluk still support for the life of the fish. Fish species were found 55 species of 19 families with a total of 4788 individuals. Barbonymus schwanenfeldii was the highest species composition which is 18.9% and abundance of 290.33 individuals/station. Diversity index was in medium category (H'=2.622–2.722), evenness index was in fairly criteria (E=0.670–0.693) and there are no species dominance (D=0.105– 0.126). Fishing activities on Danau Teluk is done traditionally in every day without making efforts to the fish to be more valuable economically. Fishermen generally do not know the term conservation of fish resources, so that fishing activity continous without conservation efforts and protection of fish species that are rarely encountered. While fish farming activities in Keramba Jaring Apung (KJA) focused only on Patin fish rearing and Tilapia. |
