The Escalating threat of climate change-driven diseases in fish: Evidence from a global perspective - A literature review.

Climate change has brought significant alterations to the aquatic environment, leading to the rapid spread of infectious fish diseases with increasing water temperatures. It is crucial to understand how aquatic pathogens will impact fish in the context of climate change. This study aimed to assess the effects of climate change on fish diseases globally.

Effects of Osmotic Stress on the mRNA Expression of , , , , and in the Pituitary and Osmoregulatory Organs of Black Porgy, .

In euryhaline teleost black porgy, , the glucocorticoid receptor (), growth hormone receptor (), prolactin ()-receptor (), and sodium-potassium ATPase alpha subunit () play essential physiological roles in the osmoregulatory organs, including the gill, kidney, and intestine, during osmotic stress. The present study aimed to investigate the impact of pituitary hormones and hormone receptors in the osmoregulatory organs during the transfer from freshwater (FW) to 4 ppt and seawater (SW) and vice versa in black porgy. Quantitative real-time PCR (Q-PCR) was carried out to analyze the transcript levels during salinity and osmoregulatory stress.

Localization of the Neuropeptide Arginine Vasotocin and Its Receptor in the Osmoregulatory Organs of Black Porgy, : Gills, Kidneys, and Intestines.

The neurohypophysial hormone arginine vasotocin () and its receptor () regulates ions in the osmoregulatory organs of euryhaline black porgy (). The localization of and transcripts in the osmoregulatory organs has yet to be demonstrated. Thus, in the present study, we performed an in situ hybridization analysis to determine the localization of and in the gills, kidneys, and intestines of the black porgy.

Expression and Transcript Localization of , and in the Early Brain of the Orange-Spotted Grouper .

We investigated the developmental expression and localization of and transcripts in the brain of the juvenile orange-spotted grouper in response to steroidogenic enzyme gene at various developmental ages in relation to gonadal sex differentiation. The transcripts were significantly higher from 110-dah (day after hatching) and gradually increased up to 150-dah. The mRNA, on the other hand, showed a decreased expression during this period, in contrast to expression.
