Perairan Waduk Gajah Mungkur merupakan tipe perairan yang tergenang mempunyai dan arti penting bagi perikanan. Plankton di perairanWadukmempunyai peranan bagi sumberdaya perikanan, antara lain sebagai produsen primer dan dapat dijadikan sebagai indikator kualitas lingkungan perairan. Kelimpahan plankton di suatu perairan dipengaruhi oleh parameter lingkungan perairan. Penelitian ini bertujuan untukmengetahui tingkat kesuburan perairan, kelimpahan dan keanekaragaman plankton Penelitian dilakukan bulan Pebruari - Nopember 2010 dengan frekuensi pengambilan contoh sebanyak empat kali yaitu pada bulan Pebruari, Mei, Juli dan Nopember. Analisis tingkat kesuburan perairan dengan metode Carlon’s dapat diketahui perairan Waduk Gajah Mungkur termasuk katagori perairan dengan tingkat kesuburannya tinggi.Waduk GajahMungkur termasuk perairan dengan kelimpahan plankton tinggi dan keanekaragaman plankton rendah yang didominansi oleh Synedra ulna Gajah Mungkur reservoir is a lentic water and has significance impact for fishery. Plankton in the reservoir as the primary producer has an important role on fisheries, could be used as an indicator of aquatic environmental quality. Abundance of plankton will be influenced by environmental condition including water quality. The purpose of this study to determine the productivity level of water quality, abundance and diversity of plankton. The study was conducted from February to November 2010, with schedule of sampling was in February, May, July and November 2010. Based on analysis by Carlon’s method, the results showed that the water quality at Gajah Mungkur reservoirwas eutrophic level. Gajah Mungkur reservoir has high plankton abundance and low plankton diversity the species of plankton was dominated by Synedra ulna.
Bengawan Solo merupakan sungai yang sudah banyak mengalami perubahan sepeni waduk, bendungan, sodetan, dan lain-lain. Bengawan Solo melewati Propinsi Jawa Tengah dan Timur yang padat penduduk sekitar 15,2 juta jiwa tinggat di satuan wjlayah Sungai Bengawan Solo dan banyak terdapat industri.
<p>Perairan rawa banjiran sangat dipengaruhi musim, saat musim kemarau mengalami kekeringan dan saat musim penghujan banjir. Ada dua kelompok ikan di rawa banjiran yaitu kelompok ikan rawa (<em>black-fish</em>) dan kelompok ikan sungai (<em>white fish</em>). Berdasar tipe habitat di rawa banjiran ada beberapa tipe suaka perikanan yaitu suaka tipe lebung, suaka tipe<br />danau rawa, suaka tipe Sungai, suaka tipe lubuk. Suaka perikanan tipe lebung: “Lebung Suak Buaya” (0,5 ha) di Lubuk Lamam Sumatera selatan terdapat stok ikan 2 ton yang didominansi oleh ikan Gabus (<em>Channa striata</em>), Tembakang (<em>Helostoma temmenckii</em>), Sepat Siam (<em>Trichopodus pectoralis</em>), Betok (<em>Anabas testudineus</em>). Suaka perikanan tipe danau:<br />“Danau lindung Empangau “ (124 ha) di Kapuas Hulu Kalimantan Barat terdapat stok ikan 5.700 ekor/ha didominansi oleh ikan Haruan (<em>Channa striata</em>), Entukan (<em>Thynnichthys thynnoides</em>), Biawan (<em>Helostoma temmenckii</em>), Tengadak (<em>Barbonymus schwanenfeldii</em>). Suaka perikanan tipe sungai “Kapak Hulu” (segmen sungai panjang 1 km, lebar 30 m) di Lubuk Lamam Sumatera selatan terdapatstok ikan 4 ton didominansi oleh ikan Lais (Kryptopterus kryptopterus), Baung (Hemibagrus nemurus), Palau (Osteochilus hasselti), Lampam (Barbonymus schwanenfeldii). Suaka perikanan “Lubuk Gunung Isam” di Lubuk Lamam Sumatera selatan terdapat stok ikan 2 ton didominansi oleh ikan Tapa (<em>Wallago leeri</em>), Bulu Tulang (<em>Kryptopterus apagon</em>), Baung (<em>Hemibagrus nemurus</em>), Lais (<em>Kryptopterus kryptopterus</em>). Agar supaya suaka perikanan dapat berfungsi dengan baik sehingga mempunyai dampak terhadap masyarakat sekitarnya maka suaka tersebut harus dikelola dengan tepat mulai dari penentuan lokasi yang tepat, sarana prasarana yang diperlukan, serta kelembagaan dan pengawasan.</p><p>Floodplain waters are strongly influenced by season, drought during dry season and floods in rainy season. There are two groups of fish in the swamp namely the swamp fishgroup (black fish) and river fish group (white fish). Based on the type of habitat in the swamp flood, there are several types of fish reserves namely floodplain pool reserve, swamp lake reserve, river segment reserve, and deep pool of the riverreserve. Floodplain pool reserve type:” Suak Buaya Reserve”(0.5 ha) in southern Sumatra contained 2 tons of fish stocks dominated by snakehead, kissing gourami, Snakeskin gourami, climbing perches. Swamp lake reserve type: Empangau Lake Reserve (124 ha) in West Kalimantan with5.700 fish/ha dominated by Snakehead fish, minnows or carp,kissing gourami, Tinfoil barb. River segment reserve type: “Kapak Hulu Reserve “ (river segment, length =1 km and width =30 m) in southern Sumatra contained 4 tons of fish dominated by Sheatfishes, Catfish, Hard Lipped Barb, Tinfoil barb. Deep pool of the river reserve type: “Lubuk Gunung Isam Reserve” in southern Sumatra contained 2 tons of fish dominated by Butter catfish, Fur Bones, Catfish, Sheatfishes.In order to conserve fish reserves properly so that they are beneficial for the surrounding community the reserves shall be appropriately managed, either in determining the location, identifying the necessary infrastructure, as well as proposing related institutions and supervision activites.</p>
Suatu penelitian yang bertujuan melihat penerapan konsep ko-manajemen, yangmerupakan suatu pengaturan kemitraan dengan menggunakan kemampuan dan minatmasyarakat lokal, telah dilakukan pada dua reservat yaitu di Jambi dan Sumatera Selatan. Pengumpulan data primer dilakukan melalui dilengkapi dengan panduan daftar pertanyaan sesuai dengan tujuan penelitian.
