“…Oocyte atresia has been reported as an endocrine disorder of female aquatic animals, which is inflicted on oogenesis owing to various environmental factors. The species currently affected include the common carp ( Blazer, 2002 ); sole, Solea solea ( Cuevas et al., 2015 ); brown bullhead, Ameiurus nebulosus ; smallmouth bass, Micropterus dolomieu ; yellow perch, Perca flavescens ( Pinkney et al, 2017 ) and Mytilus trossulus ( Smolarz et al, 2017 ). The histological properties seen in the rock bream during the present study were similar to those from these previous studies.…”

We report on the gonadal structure abnormality and intersexuality found from a survey regarding the reproductive potential of the rock bream, Oplegnathus fasciatus , along the southern coast of Korea. In total, 448 samples were collected for histological analysis (total length 27.5±6.8 cm; total weight 522.9±385.6 g). The sex ratio (F:M) was 1:0.46 (n=307:141), with 68.5% being females. The frequency of oocyte atresia and ovarian neoplasm in the females was 85.3% and 21.5%, respectively, and the frequency of testicular lobule and cyst deformation and testicular neoplasm in the males was 73.1% and 37.6%, respectively. The scale formation in the ovary and testis was approximately 2.0% for both sexes. The intersexuality was 42.2%, with the intersexuality among females being 49.5%, which was significantly higher than that of males (26.2%). Such findings indicate a negative impact on the reproductive output of the rock bream along the southern coast of Korea; however, a more detailed study is required to ascertain accurate causes.

“…Further on, histopathological lesions in gills and liver are a powerful signal of the effects caused by exposure to pollutants in flatfish, including sole (Bernet et al, 1999;Stentiford et al, 2003;Feist et al, 2004). Multi-organ histopathological approaches have been applied in sole in field and laboratory studies (Costa et al, 2009;Oliva et al, 2013;Cuevas et al, 2015a;Cuevas et al, 2015b;Briaudeau et al, 2020;Briaudeau et al, 2021). The use of different target organs for histopathological assays is essential to identify alterations in vital functions such as metabolic processes (e.g.…”

IntroductionEstuarine ecosystems are under high anthropogenic pressure and receive a wide Q7 variety of contaminants, including metals. They can remain trapped in estuarine sediments at high concentrations for long periods but eventually they can be released to the overlying water and become toxic for the resident benthic biota. As a consequence, biomonitoring programs surveying the health status of estuaries and coastal areas count with benthic species for the assessment of health disturbances in these specific ecosystems. The present investigation aims at recognizing toxicopathic effects elicited in estuarine life stages of the benthic fish Solea senegalensis on exposure to waterborne Cd, a model compound for metal contamination.MethodsBiological responses to metal exposure were assessed based on the application of a “biomarker + histopathology” approach. Two-year old sole juveniles were exposed to various concentrations of waterborne Cd for 3 and 7 days (Control; Low Cd: 1 µg/l; Mid Cd: 10 µg/l and High Cd: 1000 µg/l). Liver samples were collected for chemical analysis at day 7. Biological samples were collected at days 3 and 7 for biochemical (brain and liver), histochemical (liver) and histopathological analysis (liver, gills and gonad).ResultsBrain acetyl cholinesterase was inhibited after 7 days exposure, indicating neurotoxic effects on exposure to 1000 µg Cd/l. Hepatic catalase and glutathione-Stransferase were induced at day 3 and inhibited at day 7, which suggests a bell-shaped response. A dose-dependent lysosomal membrane destabilization in hepatocytes was recorded at day 7. In parallel, histopathological lesions in gills, liver and gonad were more frequent at day 7 in soles exposed to high Cd concentrations.DiscussionOverall, the “biomarker + histopathology” approach revealed that waterborne Cd causes toxicopathic effects in sole juveniles upon exposure to environmentally relevant concentrations (10 µg Cd/l). The effects were clearly time dependent, and thus it is conceivable that more severe biological effects would be elicited by these low concentrations of Cd at longer exposure periods. Therefore, biomarkers and histopathology in combination provide early-warning indications of altered health status after waterborne Cd exposure in sole juveniles, a prospective sentinel for biological effects assessment of metal contamination in pollution monitoring programs in estuaries and coastal areas.

“…Otros trabajos que han empleado índices histopatológicos en peces como protocolos de contaminación han evaluado el estado de salud de las especies Solea senegalensis y Platichthys flesus, cada uno con un enfoque de índice diferente (Costa et al, 2009;Lang et al, 2006). Posteriormente se realizó una correlación entre ambos índices y se observó que al aplicar estos índices diferentes entre sí, los resultados tienden a ser similares, sin embargo, se sugiere que el índice propuesto por Costa et al (2009) muestra mayor sensibilidad en cuanto a la comprensión de los mecanismos histopatológicos ya que involucra el daño tisular (factor de importancia patológica) junto con la difusión de cada uno (grado de diseminación), mientras que el de Lang et al (2006) solo considera la lesión más grave y su diseminación (Cuevas et al, 2015b).…”

“…La aplicación de este tipo de enfoque permite la obtención de información valiosa para la clasificación de zonas de estudio, la relación de los efectos ambientales con la fuente de contaminación, la determinación del estado de salud, tener un registro basificado de los cambios a través del tiempo y facilitar el análisis de datos (Cuevas et al, 2015b(Cuevas et al, , 2015aMatadamas-Guzman et al, 2019) Las técnicas inmunohistoquímicas se consideran métodos que proporcionan información valiosa para diagnosticar diferentes patologías (Miyamoto et al, 2018). En los moluscos bivalvos, estas técnicas también se han aplicado para analizar diferentes biomarcadores asociados con el estrés ambiental o con la presencia de agentes contaminantes en áreas específicas.…”

“…En segundo lugar, se relaciona la prevalencia de alteraciones con el nivel de exposición para determinar la sensibilidad de la almeja a los contaminantes que podrían estar presentes en Tecolutla. La histopatología se utiliza ampliamente para reconocer los efectos del estrés ambiental en los organismos (Bernet et al, 1999;Boscolo Papo et al, 2014b, 2014aCosta et al, 2013;Cuevas et al, 2015aCuevas et al, , 2015bSıkdokur et al, 2020;Usheva et al, 2006). Se ha utilizado en varios organismos para determinar el estado de salud de los cuerpos acuáticos (Boscolo Papo et al, 2014a;Chalghmi et al, 2020;Costa et al, 2013;Usheva et al, 2006).…”
