AbstractIn this study, we analyzed the length-weight relationships (LWRs), total length (TL)-standard length (SL) relationships (LLRs), and Fulton's condition factor (K) of male and female black rockfish Sebastes schlegelii Hilgendorf, 1880 in Lidao Bay, Yellow Sea, China. Among the 729 S. schlegelii specimens sampled seasonally in February, May, August and November between 2011 and 2015, most were males (sex ratio = 1 male:0.79 female). The LWRs of each season were significant (P < 0.05), and all coefficients of determination (r (2)) were higher than 0.95. The values of the slope (b) estimated for each LWR regression varied from 2.947 to 3.277 and were lower in spring than those in other seasons, especially in females. The LLRs calculated as the regression of TL on SL and vice versa were linear. The values of K ranged from 0.791 to 2.981 in males (n = 407) and from 0.752 to 2.681 in females (n = 322), and the highest value was found in spring. The present results provide baseline information on biological data of LWRs, LLRs, and K for S. schlegelii in this area, and will be useful in further studies on stock management of S. schlegelii.
