Analysis of length-weight relationships, patterns of growth, and knowing fish consumption factors in various places are very important for better fisheries management. This study aims to analyze the length-weight relationship, growth patterns and condition factors, mullet fish (Mugilidae) caught in the waters of Panjang Island, Galang District, Batam City, during May-June 2019. The length-weight relationships were analyzed using the Linear Allometric Model (LAM) method. The condition of fish in the wild is determined by the analysis of relative weight conditions (Wr) and Fulton (K) conditions. Found 3 species of mullets namely L. tade, L.vaigiensis, and C. crenilabis. The lengthweight relationship of L. tade has the equation W = 0.0147L2,882, L. vaigiensis has the equation W = 0.0104L3,079, and C. crenilabis has the equation W = 0.0253L2.703. L. tade and C. crenilabis species have negative allometric growth patterns with exponents 'b' <3, 2.882 and 2.703. Whereas L.vaigiensis has positive allometric growth with an exponent value of 'b'> 3 (3,079). Based on the coefficient of determination (R2) all species show a close relationship between weight gain and fish length. The condition factor value indicates the environment is in good condition.
