“…Studies conducated by Utomo et al (2005) and Dharyati et al (2010) also found that during wet season (November -January) striped catfish caught in Keduang inlet were larger than 2 kg and ready to spawn. According to Legendre et al (1999) after the Kristanto et al (2005), the gonad of pond cultured striped catfish will mature after 19 month, and spawn during the wet season from October to April.…”

“…Berdasarkan penelitian Utomo et al (2006) dan didukung oleh Adjie (2011) bahwa daerah hulu Sungai Bengawan Solo termasuk Bendungan Colo didominasi famili ikan Cyprinidae, diantaranya Barbodes gonionotus, Barbodes spp., Barbodes balleroides, Barbodes collingwoodi, Hampala macrolepidota, Rasbora caudimaculata, Ostechilus hasseltii, Labiobarbus leptocheilus, dan Parachela oxygastroides. Faktor fisik yang paling berpengaruh terhadap pembendungan sungai yaitu kecepatan arus, faktor ini akan mempengaruhi keragaman jenis dan pola distribusi ikan (Tjokrokusumo, 2008).…”

The objective of the present study was to determine the diversity fishes in Colo Dam ecosystem and grouping its based on morphological characteristics. Sampling was conducted in September to October 2017 at Sukoharjo Colo Dam Central Java used the purposive random sampling method. Identification of fish species based Kottelat (1993). The diversity of fish was calculated using Shannon Wiener's diversity index. The relationship between abiotic factors and the diversity of fish was analyzed by regression test. Grouped fish with the Ntsys cluster method (2.02i). The results showed that the diversity of Colo Dam fish at station III was higher (1.16) than at stations I, II, and IV (0.84, 0.82, and 1.15), the abiotic factors affecting the diversity of fish species, and fish species that have large morphological equations have a high coefficient of similarity value in dendogram analysis.Penelitian ini bertujuan untuk menganalisis keanekaragaman dan pengelompokan ikan pada di Bendungan Colo. Pengambilan sampel dilakukan pada bulan September-Oktober 2017 di Bendungan Colo Sukoharjo menggunakan metode Purposive sampling. Identifikasi spesies ikan berdasarkan Kottelat (1993). Keanekaragaman ikan dihitung menggunakan indeks keragaman Shannon Wiener. Hubungan antar faktor abiotik dengan keanekaragaman ikan dianalisis dengan uji regresi. Pengelompokan ikan dengan metode cluster Ntsys (2.02i). Hasil penelitian menunjukkan bahwa keragaman ikan Bendungan Colo di stasiun III lebih tinggi (1,16) dari pada stasiun I, II, dan IV (0,84; 0,82; dan 1,15), faktor abiotik mempengaruhi keanekeragaman jenis ikan, dan jenis-jenis ikan yang memiliki persamaan morfologi yang besar memiliki nilai koefisien kemiripan yang tinggi dalam analisis dendogram.

“…Di sisi lain jambal sius dapat tumbuh dan berkembang dengan baik karena banyak tersedia pakan alami yang sesuai yaitu plankton dan detritus (Purnomo et al 2003). Selanjutnya Utomo et al (2005) menyebutkan bahwa jambal sius dapat berkembang dengan baik karena terdapat daerah pemijahan di Waduk Gajah Mungkur banyak, terutama daerah inlet Keduang. Menurut Utomo et al (2010) Waduk Gajah Mungkur telah berdampak negatif terhadap kualitas perairan, karena banyak sisa pakan dan kotoran ikan yang lolos ke perairan dan mencemari perairan sehingga dapat menyebabkan pertumbuhan mikro algae yang cepat.…”

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.
