1. Distribusi lokal % = Li / Lt x 100 %a. Ikan Belanak% = 4 / 10 x100%% = 40 %b. Ikan Cirik % = 6 / 10 x100%% = 60 %c. Ikan Keurong % = 2 / 10 x 100%% = 20 %d. Ikan Todak% = 4/ 10 x 100 %% = 40 %e. Ikan Gabue% = 4 / 10 x 100 %% = 40 %

2. Indeks Diversitas H = (Pi x log Pi)

a. Ikan BelanakH = 0,4 x log 0,4H = 0,4 x (-0,39)H = -0,79

b. Ikan Cirik H = 0,6 x log 0,6 H = 0,6 x (-0,22)H = -0,14

c. Ikan KeurongH = 0,2 x log 0,2H = 0,2 x (-0,69)H = -0,13

d. Ikan TodakH = 0,4 x log 0,4H = 0,4 x (-0,39)H = -0,15

e. Ikan GabueH = 0,4 x log 0,4H = 0,3 x (-0,39)H = -0,15H=(0,2 x log(0,2))+ (0,4 x log(0,4))+ (0,2 x log(0,2))+ (0,3 x log(0,3))+ (0,3 x log(0,3))= ( -0,79 ) + (-0,14) + (-0,13) + (-0,15) + (-0,15)= -1,363. Indeks kekayaan jenis atau Spesies richnes index, d (margalef index)D = S-1/log ND = 5-1/log 20 D = 4/1.30D = 3.074. Indeks Kemerataan, Evenness index, J (Pielouus index)H = ( -0,79 ) + (-0,14) + (-0,13) + (-0,15) + (-0,15)H = -1,36J = H/log SJ = -1,36/log 5J = -1,36/0,69J = -1,97
