Length-weight relationship, shell dimension and condition factor of spider conch, Lambis lambis (Strombidae) in Khanh Hoa, Vietnam

Abstract

The present study examined the length-weight, length-length relationships and condition factor (K) of spider conch, Lambis lambis collected in Khanh Hoa province, Viet Nam). Length - weight relationship equations were W = 0.2088 L2.6116 and W = 0.0932 L2.9826 for female and male spider conch, respectively. The b value was negative allometric for female spider conch, but isometric for male spider conch. Length – weight and shell dimension were significant correlation, with r2 over 0.885. Female is generally bigger and heavier than male the condition factor also higher in female than in male. Condition factor (CF) and relative weight (Wr) significantly differ (P
