Some growth characteristics of silver stripe round herring Spratelloides gracilis (Tem. & Schl., 1846) in Nha Trang bay, Khanh Hoa

This paper presents the results on the growth of Spratelloides gracilis (Temminck & Schlegel, 1846) in Nha Trang bay (Khanh Hoa province, Vietnam). The analyzed results on the length of 4,301 individuals show that it is a small species, the size ranges 20-85mm in fork length with mean 58.35±11.47mm and total weight from 0.03 - 5.54g with mean 1.79 ± 1.01g with dominant length group from 60-64mm (19.01%) for 2005 and ranges 20-85mm in fork length with mean 51.17± 12.94 mm and total weight from 0.03 - 5.58g with mean 1.20 ± 1.0g with dominant length group from 55-64 mm (16.19%) for 2007. The correlation between fork length and weight from 2,313 inviduals is as follow: a= 0.0048 and b= 3.27 (n=2,313, p<0.05). This is short-lived species with quick growth rate. The growth parameters of equation von Bertalanffy are K = 4.2 and L∞ = 94.5. The analysis of length groups for months shows that the length of fish in one month of age is from 20-30mm and 83-87mm for seven months of age.
