Abstract

ABSTRACT Engin, S.; Gurkan, S., and Taskavak, E., 2024. Cellular changes in liver tissue of adult common sole (Solea solea L. 1758) in the Aegean Sea, Turkey. Journal of Coastal Research, 40(4), 740–748. Charlotte (North Carolina), ISSN 0749-0208. In this study, cellular changes and biological indices in the liver tissue of the common sole, Solea solea (L. 1758), are investigated based on sex, size groups, and seasons. The specimens used in the study were obtained monthly between 2019 and 2020 from commercial trawlers and small scale–fishing operations in the fishing grounds of Izmir Bay, the Aegean Sea coast of Turkey. A total of 240 common sole fish (166 female, 66 male, 8 immature) were used in this study. In the obtained specimens, the male: female ratio was determined as 0.39:1 (χ2 = 33.19; p > 0.05), whereas the length–weight relationship was calculated as W = 0.009TL2.97 (R2 = 0.86) for females and W = 0.009TL3.27 (R2 = 0.91) for males. Four size groups (19–22, 23–26, 27–30, >30cm) were established in the study. Significant histological changes, such as macrovesicular steatosis degenerations, were observed in the liver tissue of the examined fish, especially in larger size groups. Females exhibited higher levels of condition and hepatosomatic index values compared with males, possibly because they are more susceptible to liver degeneration. During the summer months, liver degeneration is more striking due to hunger among common soles. Based on these results, 36.7% of the specimens caught from fishing grounds in Izmir Bay have normal liver tissues, whereas 11.3% have macrosteosis and 8.3% have a sinusoidal hemorrhage.

土耳其爱琴海成年鳎鱼（Solea solea L. 1758）肝组织细胞的变化

ABSTRACT Engin, S.; Gurkan, S., and Taskavak, E., 2024.土耳其爱琴海成年普通鳎鱼（Solea solea L. 1758）肝脏组织的细胞变化。沿海研究期刊》，40（4），740-748。夏洛特（北卡罗来纳州），ISSN 0749-0208。本研究调查了普通鳎鱼（Solea solea (L. 1758)）肝脏组织中的细胞变化和生物指数，以性别、体型组和季节为基础。研究中使用的标本是 2019 年至 2020 年期间每月从土耳其爱琴海沿岸伊兹密尔湾渔场的商业拖网渔船和小规模捕捞作业中获得的。本研究共使用了 240 尾普通鳎鱼（166 尾雌鱼、66 尾雄鱼、8 尾未成熟鱼）。所获标本的雌雄比例为 0.39:1 (χ2 = 33.19; p > 0.05)，雌鱼的长度-重量关系计算结果为 W = 0.009TL2.97 (R2 = 0.86)，雄鱼的长度-重量关系计算结果为 W = 0.009TL3.27 (R2 = 0.91)。研究中设立了四个体型组（19-22、23-26、27-30、>30 厘米）。在受检鱼类的肝组织中观察到明显的组织学变化，如大泡性脂肪变性，尤其是在较大规格组中。与雄鱼相比，雌鱼表现出更高的体况和肝功能指数值，这可能是因为雌鱼更容易发生肝脏退化。在夏季，由于普通鳎鱼的饥饿，肝脏退化更为显著。根据上述结果，在伊兹密尔湾渔场捕获的标本中，36.7%的肝组织正常，11.3%的肝组织大骨节病，8.3%的肝组织窦状出血。

期刊介绍： The Journal of Coastal Research (JCR) is one of the leading international journals for coastal studies and processes, and is published bi-monthly by the Coastal Education & Research Foundation [CERF]. By covering the entire field of coastal research, the JCR encompasses all subjects relevant to natural and engineered environments (freshwater, brackish, or marine) and the protection/management of their resources in the vicinity of coastlines of the world. Even though the journal broadly focuses on immediate shoreline zones, the JCR also embraces those coastal environments that either reach some indefinite distance inland or that extend seaward beyond the outer margins of the sublittoral (neritic) zone. The JCR disseminates accurate information to both the public and research specialists around the world on all aspects of coastal issues in an effort to maintain or improve the quality of our planet''s shoreline resources.
