      Ikan kapasan merupakan salah satu jenis dari famili Gerreidae yang memiliki nilai ekonomi yang tinggi di perairan Muara Angke, Jakarta Utara. Informasi mengenai aspek makanan ikan kapasan sangat diperlukan sebagai dasar pengelolaan sumberdaya ikan kapasan secara berkelanjutan. Penelitian ini bertujuan untuk menganalisis makanan ikan kapasan (Gerres filamentosus Cuvier, 1829) di perairan Muara Angke, Jakarta Utara yang meliputi komposisi jenis makanan, luas relung, dan tumpang tindih makanan. Pengambilan contoh ikan dilakukan dengan menggunakan jaring rajungan (ukuran 1-3 inch) di perairan Muara Angke selama 6 bulan, pada Agustus 2024 sampai Januari 2025. Analisis data yang digunakan antara lain distribusi frekuensi panjang, indeks bagian terbesar, luas relung makanan, indeks isi lambung, tumpang tindih makanan. Hasil penelitian menunjukkan bahwa ikan kapasan merupakan ikan omnivora cenderung karnivora dengan makanan utama berupa krustasea. Komposisi makanan ikan kapasan tidak memiliki perbedaan signifikan antara ikan jantan dan betina.
