摘要
本文对金头鲷(Sparus aurata Linnaeus, 1758)的年龄和生长进行了研究。2015年1月至12月期间，从土耳其爱琴海北部海岸的商业鱼贩处共采集了126个标本。年龄标本叉长29.5 ~ 48.0 cm，总重量425.00 ~ 21000g，平均38.5 cm, 101.23 g。长度-权重关系估计为W = 0.0053FL3.03 (R2 = 0.95)。所有样本的von Bertalanffy生长方程计算为𝐿∞= 52.8 cm, k = 0.29 year-1，𝑡0 = -1.25 year。生长性能指数( ')为2.91。目前还没有对爱琴海北部的这种生物进行研究。因此，本研究为该地区的物种研究提供了有价值的信息。
Age and growth of gilthead sea bream (Sparus aurata Linnaeus, 1758) from Northern Aegean Sea (Turkey)
The age and growth of gilthead sea bream (Sparus aurata Linnaeus, 1758) were studied in the present study. A total of 126 specimens were collected from commercial fishmongers during the period between January 2015 and December 2015 from the northern Aegean coasts of Turkey. Fork length and the total weight of aged specimens ranged from 29.5 to 48.0 cm and from 425.00 to 2100.00 g, with a mean of 38.5 cm and 101.23 g, respectively. The length-weight relationship was estimated as W = 0.0053FL3.03 (R2 = 0.95). The von Bertalanffy growth equations were computed as 𝐿∞ = 52.8 cm, k = 0.29 year-1, 𝑡0 = -1.25 year for all samples. The growth performance index (𝛷′) was found as 2.91. There is no study on the biology of the species for the northern Aegean Sea. Therefore, this study provides valuable information for the species in this area.
