Abstract

Microalgae play an essential role in aquaculture as primary producers, serving both as natural feed and as bioindicators for assessing pond water quality. The presence of specific microalgal taxa is crucial for evaluating aquatic conditions and identifying potential natural feed sources. This study aimed to identify microalgal species found in African catfish (Clarias gariepinus) culture ponds and to determine their ecological roles. A descriptive survey method was applied. Water samples were collected using a plankton net from three catfish culture ponds during August–September 2025. Identified microalgae were morphologically classified and analyzed for their potential as bioindicators based on literature review using Palmer’s Pollution Index. The results revealed 16 genera belonging to three divisions: Bacillariophyta (diatoms), Chlorophyta (green algae), and Cyanophyta (blue-green algae). Two genera of Bacillariophyta were identified—Aulacoseira and Synedra. Chlorophyta was the most dominant division, comprising 11 genera: Actinastrum, Coelastrum, Dictyosphaerium, Golenkinia, Micractinium, Oocystis, Pandorina, Pediastrum, Scenedesmus, Staurastrum, and Ulothrix. Cyanophyta included three genera—Anabaena, Aphanocapsa, and Spirulina. Among these, Scenedesmus and Pediastrum (Chlorophyta) are commonly used as natural feed, whereas Cyanophyta members are often utilized as water-quality bioindicators. The diversity and abundance of microalgae observed in the catfish ponds indicate organic enrichment, yet they also provide valuable potential as natural feed sources.

Abstract

Mikroalga merupakan salah satu organisme akuatik mikroskopis uniseluler yang dapat melakukan fotosintesis dan bersifat kosmopolit. Mikroalga dalam budidaya perairan dapat digunakan sebagai pakan alami organisme budidaya.  Tujuan penelitian ini yaitu untuk mengeksplorasi jenis-jenis mikroalga yang ditemukan di kolam budidaya ikan nila (Oreochromis niloticus) sebagai kandidat pakan alami. Penelitian dilaksanakan pada bulan Juli sampai Agustus 2025, dengan metode survey dengan melakukan pengambilan sampel mikroalga langsung pada kolam budidaya ikan nila (Oreochromis niloticus) di Kelurahan Mojoroto, Kota Kediri. Hasil penelitian menunjukkan bahwa mikroalga yang didapatkan terdiri atas 4 divisi dengan 15 genus. Divisi mikroalga yang ditemukan meliputi Bacillariophyta, Chlorophyta, Cyanophyta dan Euglenophyta. Divisi Bacillaryophyta terdiri 3 genus yaitu Aulacoseira, Gomphonema dan Synedra. Divisi Cyanophyta hanya terdiri 1 genus yaitu Aphanocapsa. Divisi Chlorophyta ditemukan dengan genus terbanyak yaitu 9 genus meliputi Coelastrum, Dictyosphaerium, Golenkinia, Kirchneriella, Oocystis, Pandorina, Pediastrum, Scenedesmus dan Staurastrum. Divisi Euglonophyta ditemukan 2 genus yaitu Euglena dan Phacus. Mikroalgae yang ditemukan terdapat yang telah diekplorasi kegunaannya, namun sebagian besar juga masih belum diekplorasi. Mikroalgae yang potensial sebagai pakan alami namun masih terbatas penelitiannya diantaranya yaitu Dictyospaerium dan Kirchneriella. Penemuan mikroalgae ini memiliki potensi untuk diekplore lebih lanjut untuk dimanfaatkan sebagai pakan alami bagi budidaya perairan.
