Karakteristik shoaling ikan pelagis kecil di Perairan Selat Bangka pada musim timur adalah sebagai berikut : Kelompok pertama, berbentuk elips dengan ukuran panjang 4.3 m, berada pada kedalaman 8,9 m dan posisi shoaling ikan pada kedalaman 25.2% dari dasar perairan. Energi akustik rata-rata (-46,4) dB. Kelompok kedua, berbentuk elips dengan ukuran panjang 6,2 m, berada pada kedalaman 5,5 m dan posisi shoaling ikan pada kedalaman 66,4% dari dasar perairan. Energi akustik rata-rata (-44,7) dB.

Echogram have limited by an inability to distinguish between the echoes of co-occurring species then incorrect to determine the species composition and shoaling of fishes. Particularly in multi species environments. Small pelagic fish shoal characteristics can be described as follows: First group, The fish shoals were in ellipsoidal shape with length 4.3m. Mean depth of the fish shoals were in 8.9 m and relative altitude 25.2% from sea bottom. Average acoustic energy was -46.4 dB. Second group, The fish shoals were in ellipsoidal shape with length 6.2m. Mean depth of the fish shoals were in 5.5 m and relative altitude 66.4% from sea bottom.
