“…In addition, the rapid proliferation of S. testicularis within sea bass could be favoured by a depressed immune status of the males, as the spawning period (Corbel, 1975) and low water temperatures (Avtalion, Wishkovsky & Katz, 1980;Angelidis, Baudin-Laurencin & Youinou, 1988) have been cited as immune depressing factors. The lack of epidemiological data on other testicular parasites makes comparisons difficult.…”

The population dynamics of Sphaerospora dicentrarchi and S. testicularis, myxosporean parasites of sea bass (Dicentrarchus labrax), was studied in different groups of cultured and wild fish. S. dicentrarchi prevalence was higher for wild fish (100%) than for cultured ones (70.5%). Infection levels increased with host age and there were no significant sex differences in cultured fish. Among parasitized organs, the gall bladder and intestine registered the highest infection levels in wild and cultured fish. A progressive increase in infection levels of S. testicularis was observed in cultured males during the spawning season in four consecutive periods. The evolution of the percentage of the different parasitic stages is pointed out. The infection seems to be related to water temperature and gonadal maturation.

A commercial P-glucan known for its ~mmunostimulatory effects in several fish species was tested in turbot ScophthalniusmaximusL.. both as an oral immunostimulant and as an adjuvant for oral vaccination. Some non-specific immune parameters were tested after a 5 wk feeding period with a commercial diet mixed with yeast P-glucan. Furthermore, during the last 5 d of the feeding period, half of the fish were orally vaccinated by mixing the commercial pellets with an anti-vibriosis vaccine (Vibriffa bain ND). The oral administration of P-glucan induced no reduction in mortality after a challenge with a virulent Vibrio anguillarum (strain 408). In contrast, a single oral vaccination resulted in protection against V anguillarum. The use of P-glucan as an adjuvant did not reduce the mortality rate more than did the single vaccination. An increase in white blood cell count was observed after the administration of only P-glucan. The plasma complement activity was not influenced by any of the treatments. In contrast, lysozyme activity was enhanced after administration of the adjuvanted vaccine. An increase in the chemiluminescent response of opsonised zymosan-stimulated head-kidney leucocytes was less obvious and no significant results were recorded.

“…Phagocytosis is a key first-line defence mechanism of the innate immune system of fish. Respiratory burst, measured as a chemiluminescence (CL) response for the production of reactive oxygen species, was used to determine optimal temperatures for phagocytosis in head kidney cells isolated from European seabass [ 117 ]. CL levels were found to be higher at lower temperatures (5–20 °C) than at higher temperatures (25–40 °C).…”

Mediterranean Aquaculture in a Changing Climate: Temperature Effects on Pathogens and Diseases of Three Farmed Fish Species

et al. 2021

Climate change is expected to have a drastic effect on aquaculture worldwide. As we move forward with the agenda to increase and diversify aquaculture production, rising temperatures will have a progressively relevant impact on fish farming, linked to a multitude of issues associated with fish welfare. Temperature affects the physiology of both fish and pathogens, and has the potential to lead to significant increases in disease outbreaks within aquaculture systems, resulting in severe financial impacts. Significant shifts in future temperature regimes are projected for the Mediterranean Sea. We therefore aim to review and discuss the existing knowledge relating to disease outbreaks in the context of climate change in Mediterranean finfish aquaculture. The objective is to describe the effects of temperature on the physiology of both fish and pathogens, and moreover to list and discuss the principal diseases of the three main fish species farmed in the Mediterranean, namely gilthead seabream (Sparus aurata), European seabass (Dicentrarchus labrax), and meagre (Argyrosomus regius). We will attempt to link the pathology of each disease to a specific temperature range, while discussing potential future disease threats associated with the available climate change trends for the Mediterranean Sea.
