The severity, frequency, and duration of extreme events, in the context of global warming, have placed many marine ecosystems at high risk. Therefore, the application of methods that can mediate the impacts of global warming on marine organisms seems to be an emerging necessity in the near term. In this context, enhancing the thermal resilience of marine organisms may be crucial for their sustainability.

The study was designed in an effort to evaluate the influence of seasonality in several physiological feauteres of high commercial importance that may affect feed intake and growth. We determined glycogen, lipids and proteins levels, and cellular energy allocation (CEA) as a valuable marker of exposure to stress, which integrates available energy (Ea) and energy consumption (Ec).

- - The study examines the genetic diversity of five populations of the narrow-clawed crayfish (Pontastacus leptodactylus) in Greece, focusing on three translocated populations and their origins, particularly linking them to Turkish lake Eğirdir.
- - Using nine microsatellite loci, the research found that while the populations show low genetic diversity in terms of alleles, they still exhibit overall genetic diversity, which indicates potential local adaptation despite overfishing and habitat degradation challenges.
- - The findings highlight the Evros river population as having high genetic diversity, making it a valuable candidate for conservation efforts and future restocking initiatives, marking a significant first step in developing management practices for crayfish populations in Greece.
The copepod Lernathropus kroyeri constitutes one of the major parasites for the Mediterranean aquaculture, infesting the sea bass Dicentrarchus labrax causing thus disruptions of growth performance and occasionally mortalities. Despite the large spread and the high frequency of this parasite in mariculture farms of Eastern Mediterranean, L. kroyeri genetic profile from aquaculture as well as the pathophysiological response of D.
