      Abstract
      Ikan red devil (Amphilophus labiatus) merupakan spesies asing invasif yang berasal dari Kosta Rika dan Nikaragua Amerika Tengah. Introduksi ikan red devil terjadi di beberapa perairan Indonesia, salah satunya Situ Gede Bogor. Penelitian ini bertujuan untuk menganalisis makanan dan kebiasaan makan dari ikan red devil serta peluangnya sebagai ikan invasif terhadap biota perairan di Situ Gede Bogor. Penelitian dilakukan pada bulan Ferbruari hingga Mei 2023. Analisis data yang digunakan yaitu Indeks Relatif Penting (IRP), luas relung, tumpang tindih makanan, dan biometrik organ yang berkaitan dengan kebiasaan makan ikan. Hasil penelitian menunjukkan ikan red devil memiliki makanan utama berupa krustasea (IRP=54,37-76,08%) dengan komposisi tertinggi pada sore hari di Stasiun 3 (outlet). Ikan red devil jantan dan betina merupakan omnivora-karnivora generalis dengan nilai luas relung 1,4151 dan tumpang tindih 0,9724. Ikan red devil merupakan ikan nokturnal yang aktif mencari makan pada waktu sore hari. Ikan red devil berpeluang menjadi ikan invasif di perairan Situ Gede Bogor dan menjadi kompetitor utama bagi ikan patin serta lele yang juga merupakan ikan omnivora-karnivora nokturnal.
       
      Red Devil fish (Amphilophus labiatus) is an invasive alien species from Costa Rica and Nicaragua Central America. The introduction of red devil fish populations have occurred in several Indonesian waters, one of which is Situ Gede Bogor. This study aims to analyze food and feeding habits of red devil fish and its potential as an invasive fish against aquatic biota in Situ Gede Bogor. The research was conducted in February until May 2023. Data analysis used in this research were Index of Relative Importance (IRI), niche breadth, niche overlap, and food-related biometrics organ related to feeding habits. The results showed that the red devil fish main diet consisting of crustacean (IRI=54,37-76,08%) with the highest composition in the afternoon at Station 3 (outlet). Male and female red devil fish are generalist omnivores-carnivores with a niche breadth value of 1.4151 and an overlap of 0.9724. Red devil fish are a nocturnal fish that actively forage in the afternoon. Red devil fish has the potential to become an invasive fish in the waters of Situ Gede Bogor and become a major competitor for catfish and pangas catfish which are also a nocturnal omnivorous-carnivorous fish.
