Description This study was conducted in October to November 2016 in the intertidal zone around the field laboratory of UNSRAT in Likupang. It was aimed at knowing the species and the size of trevally (Caranx spp.) migrating to the intertidal zone and their food habit. Fish sampling used a beach seine. The fish collected were 45 individuals consisting of 3 species, 22 individuals of Caranx melampygus, 21 individuals of C. papuensis, and 2 individuals of C. sexfaciatus. Body length varied from 6 to 19.9 cm for C. melampygus, 7 to 15.6 cm for C. papuensis, and 6.9 and 7.6 cm for C. sexfaciatus, respectively. There were 4 food types, shrimps, fish, crabs, and organic matters, such as shrimp’s eye and digested food. The Importance Relative Index of shrimp was the highest, 82%, followed by fish, 14%, and the lowest recorded in crab, 4%. Shrimp is major food sort of C. melampygus. The Importance Relative Index of C. papuensis and C. sexfaciatus could not be counted because of empty stomach and low number of samples. Feeding intensity of C. melampygus was 86% and that of C. papuensis was 10%, so that it was apparent that C. melampygus come to the intertidal for feeding, while C. papuensis come for other purpose.        Keywords: size, food habit, Caranx spp. ABSTRAKPenelitian ini dilakukan pada bulan Oktober-November 2016 di Daerah Intertidal Sekitar Laboratorium Lapangan UNSRAT Likupang penelitian ini bertujuan untuk mengetahui spesies dan ukuran ikan kuwe (Caranx spp) yang bermigrasi di daerah pasang-surut dan kebiasaan makanannya. Pengambilan sampel ikan menggunakan pukat pantai, ikan yang terkumpul yaitu 45 ekor yang terdiri dari 3 spesies yaitu 22 individu Caranx melampygus, 21 individu Caranx papuaensis, dan dua individu Caranx sexfaciatus. Panjang tubuh bervariasi dari 6-19,9 cm Caranx melampygus, 7-15,6 cm Caranx papuaensis untuk Caranx sexfaciatus yaitu 6,9 cm dan 7,6 cm. Terdapat empat jenis makanan yaitu udang, ikan, kepiting dan bahan organik seperti mata udang dan makanan yang sudah tercerna. Indeks Relatif Penting udang yang tertinggi yaitu 82% di ikuti oleh ikan 14% dan terendah ditemukan pada kepiting 4%. Udang merupakan makanan utama dari Caranx melampygus. Indeks Relatif Penting Caranx sexfaciatus dan Caranx papuaensis tidak dapat dihitung karena isi lambung kosong dan jumlah sampel sedikit. Intensitas makan (IM) Caranx melampygus adalah 86% dan  Caranx papuaensis 10% sehingga jelas bahwa Caranx melampygus dating ke daerah Intertidal untuk mencari makanan sedangkan Caranx papuaensis datang ke daerah Intertidal untuk tujuan lain.Kata Kunci: Ukuran, Kebiasaan Makanan, Caranx spp,
