Berdasarkan jenis ikan yang hidup di Waduk Wadaslintang, maka akan memiliki peluang kompetisi makanan terhadap sumberdaya makanan yang tersedia di perairan.

Penelitian dilakukan bulan Mei 2017 di kawasan perairan Waduk Wadaslintang, Kabupaten Wonosobo. Jumlah sampel ikan yang diperoleh 41 ekor. Kelimpahan jenis plankton yang terdapat di perairan Waduk Wadaslintang berkisar antara 424-8376 ind/l dengan jenis fitoplankton yang berasal dari kelas Bacillariophyceae , Chlorophyceae , Cyanophyceae , Xantophyceae dan Zygnematophyceae . Hasil dari perhitungan Index of Preponderance , ikan tawes, ikan mujair dan ikan nila (non KJA) memanfaatkan kelas Bacillariophyceae sebagai makanan utamanya, sedangkan ikan nila (KJA) memanfaatkan pakan buatan yang diduga pelet sebagai makanan utamanya dan kelas Bacillariophyceae sebagai makanan pelengkapnya. Berdasarkan hasil perhitungan tumpang tindih dan luas relung, diketahui beberapa kelompok yang memiliki peluang kompetisi makanan. Kelompok I adalah ikan tawes yang bersifat selektif sehingga tidak memiliki peluang kompetisi makanan, kelompok II adalah ikan mujair dan ikan nila (non KJA) yang memiliki peluang kompetisi tertinggi.

Based on the type of fish live in Wadaslintang Reservoir it will have a chance of food competition to available food resources in the waters. The research aimed to know food habits Java barb, Java tilapia and Nile tilapia that it can know the food competiton contained in it, moreover that it to know about the abundance of plankton in Wadaslintang reservoir. This research held on May 2017 in the Wadaslintang reservoir, Wonosobo regency. A total of fish is 41. The abundance of plankton in Wadaslintang reservoir ranged between 424-8376 ind/L with the type of phytoplankton derived from Bacillariophyceae, Chlorophyceae, Cyanophyceae, Xantophyceae and Zygnematophyceae.
