Karakteristikhabitatdansebaran Jenis Ikan Di Sungaikapuas Bagian Tengahdanhilir

Abstract

Sungai Kapuas memiliki keanekaragaman jenis ikan yang tinggi dilaporkan mencapai sekitar 200 spesies. Penelitian ini bertujuan untuk mengetahui karakteristik habitat serta sebaran jenis ikan di Sungai Kapuas bagian tengah dan hilir. Penelitian ini dilakukan pada bulan April, Juli, September, dan Nopember 2006. Parameter yang diamati meliputi kualitas air (suhu, kecerahan, daya hantar listrik, pH, CO2, oksigen terlarut, alkalinitas, BOD, PPO 4, N-NO3, N-NO2, COD, N-NH3, dan salinitas), habitat perairan, serta sebaran jenis ikan. Contoh air diambil dari sembilan stasiun pengamatan yaitu di bagian tengah Tengkidap, Pengembung, Pemerak, Bukit Tekenang, dan Sambar Indah dan di bagian hilir Muara Jungkat, Sungai Raya, Muara Sungai Tayan, dan Semitau, contoh air dianalisis menggunakan American Public Health Association (1986). Hasil pengamatan menunjukkan bahwa karakteristik kualitas air bagian tengah dan hilir relatif sama dan karakteristik habitat Sungai Kapuas bagian tengah merupakan daerah rawa banjiran (flood plain) yang banyak terdapat hutan rawa danmerupakan kawasan konservasi dari Taman Nasional Danau Sentarum. Karakteristik habitat Sungai Kapuas bagian hilir dipengaruhi oleh pasang surut air laut dan merupakan kawasan industri. Jenis ikan yang dijumpai di sepanjang stasiun pengamatan terdapatsekitar 123 jenis, penyebarannya terkonsentrasi di sungai bagian tengah ± 120 jenis yang didominansi oleh ikan Cyprinidae dan Sungai Kapuas bagian hilir ±85 jenis yang didominansi oleh ikan dukang (Arius stomi) dan janggut(Polynemus longipectoralis). Kapuas River has a high diversity of fish species reported to reach about 200 species. This study aimed to characterize the habitat and distribution of fish species in the Kapuas River middle and downstream sections. The study was conducted in April, July, September, and November 2006. The parameters observed included water quality (temperature, brightness, electrical conductivity, pH, CO2, dissolved oxygen, alkalinity, BOD, P-PO4, NNO3, N-NO2, COD, NH3-N, and salinity), and aquatic habitats distribution of fish species. Water samples taken from nine observation stations are in the middle Tengkidap, Pengembung, Pemerak, Bukit Tekenang, and Sambar Indah and in the downstream Muara Jungkat, Sungai Raya, Muara Sungai Tayan, and Semitau, water samples were analyzed using the American Public Health Association (1986). The results showed that characteristics of water quality downstream of the middle and relatively similar, habitat characteristics of the Kapuas River and the middle is a swamp area flood plain that there are still a lot of swamp forest and is a conservation area of the Park Lake Sentarum. Characteristics of the Kapuas River downstream habitats are influenced by tides and is an industrial area. Types of fish that are found along the observation stations are about 123 species, its distribution is concentrated at the center of the ± 120 River dominated by fish species cyprinidae and Kapuas River downstream of ± 85 species dominated by fish dukang (Arius stomi) and janggut (Polynemus longipectoralis).

Keragaman Jenis Ikan Pada Aliran Drainase Lahan Gambut Kabupaten Kubu Raya Kalimantan Barat

“…Sungai Kapuas memiliki keanekaragaman jenis ikan yang tinggi dan terdapat 125 jenis ikan di bagian tengah dan hilir (Adjie S dan Utomo AD, 2011). Sungai Kapuas di bagian hilir merupakan anak sungai Kapuas yang melewati tiga wilayah administrasi Kabupaten Kubu Raya, Kota Pontianak, dan Kabupaten Mempawah (Purnaini R et al, 2019).…”

Vitellogenesis Activity of Channa Marulioides, Bleeker, 1851, Impact of Folicle Stimulating Hormone as Reproductive Domestication

“…The availability of this fish is currently declining in its natural habitat in Indonesian waters in the Kapuas River. Local researchers reviewed the availability of Channa marulioides in the Central Kapuas River in a "small" category, namely in one season catches less than five fish per day per person, while in the lower waters of the Kapuas River Channa marulioides catches were not found (1). The decrease in the availability this fish is allegedly a result of the absence of initial efforts in fish hatcheries that result in the availability of Channa marulioides currently obtained from natural catches.…”
