Biometric relationships, condition factor and relative weight of Lingula anatina (Lamarck, 1801) at Thuy Trieu lagoon, Khanh Hoa, Vietnam


Author(s): Do Huu Hoang

Abstract: The present study investigated biometric relationships, condition factor (K) and relative weight (Wr) of Lingula anatina at two locations: Cam Hai Tay (CHT) and Cam Thanh Bac (CTB) in Thuy Trieu lagoon (Khanh Hoa province, Vietnam). Length - weight relationship equations were W = 0.0473 L3.1405 and W = 0.0728 L2.7689 for L. anatina at CHT and at CTB, respectively. The b value was isometric for L. anatina at CHT, but negative allometric for L. anatina at CTB. Length – weight and shell dimension were significant correlation, with r2 over 0.885. K and Kmean were significantly higher in CTB compared to CHT (P < 0.001). Relative weight (Wr) values of L. anatina did not significantly differ between the two locations (CHT and CTB), and Wr values of Lingula at both CHT and CTB were not significantly different from critical value (100). Relationships between Kmean and shell size were significantly linear, but with a positive correlation for the population at CHT, and an inverse correlation for the population at CTB.
