| الملخص: | The length parameters of Anadara similis were estimated with length-based methods (ELEFAN I y NSLCA) in three communities of REMACAM (El Viento, Santa Rosa and Tambillo). The length class interval that generated the lowest uncertainty was 1.5 mm. In the growth parameters estimation, L∞ was restricted to the confidence interval of 95% of the highest predicted length, and k was restricted to values between 0.10-0.20 year-1. The variability of the estimation was analysed with the jacknife technique. The growth parameters L∞ and k were unified for comparative effects with the phi prime index (Φ ). The results showed that the NSLCA method has a better development in the growth parameters estimations of A. similis, while ELEFAN I estimated superior values in growth. The estimations of Φ from the NSLCA varied between 2.60 and 2.88. No significative differences were found in the growth of A. similis between the three communities, obtaining average values of Φ of 2.81, 2.79 and 2.84 for El Viento, Santa Rosa and Tambillo, respectively. The results show that the species Anadara similis has a slow growth and that the NSLCA method combined with the jacknife technique is an acceptable approximation to estimate growth parameters. |
