Bacillariophyceae is a main food, Crustacea is additional food, and Ciliata and detritus is complementary food both for male and female fish. Electivity indeks of the fish varied from -0,99 to 0,45 (male) and -0,98 to 0,51 (female).

Ikan tembang (Clupea fibriata) merupakan salah satu sumberdaya perikanan yang cukup penting di Indonesia. Jenis ikan ini cukup banyak ditemukan di perairan Ujung Pangkah. Penelitian bertujuan untuk menganalisis makanan ikan tembang yang tertangkap di daerah tersebut.  Penelitian dilaksanakan sejak Juli sampai Desember 2005, di daerah Perairan Ujung Pangkah (Gresik, Jawa Timur), dengan pengambilan sampel ikan sebanyak 313 ekor yang terdiri atas 147 ekor jantan dan 166 ekor betina, menggunakan alat tangkap jaring insang (gill net) dan jeger (fix net). Hasil pengamatan menunjukkan bahwa ikan tembang memiliki makanan yang terdiri atas Bacillariophyceae (7 jenis), Crustacea (3 jenis), Ciliata (2 jenis), Dynophycea (2 jenis), dan detritus.  Kelompok Bacillariophyceae merupakan kelompok makanan utama, Crustacea merupakan makanan pelengkap, dan Ciliata dan detritus merupakan makanan tambahan baik pada ikan jantan maupun ikan betina.  Indeks pilihan makanan ikan tembang berkisar antara -0,99 sampai 0,45 (pada ikan jantan) dan -0,98 sampai 0,51 (pada ikan betina). Berdasarkan  indeks tersebut, Skeletonema dan Calanus merupakan jenis yang banyak dimakan ikan tembang di perairan Ujung Pangkah.
