“…Thus, the understanding of changes in blood parameters according to the water temperature could be essential to optimize striped bass performance and production. Previous studies with striped bass juveniles showed that animals kept at intermediated temperatures (between 16 and 20ºC) presented very similar serum glucose levels than observed in this study (Davis and Parker, 1990; Araújo et al, 2021; Brougher et al, 2005). Differently, the serum glucose levels in animals kept at lower water temperatures (between 5 and 14ºC) were much higher than those animals kept at higher water temperatures (between 20 and 26ºC), suggesting a strait relationship between temperature and glucose metabolism (Araújo et al, 2021; Davis & Parker, 1990).…”

Apparently, according to the serum glucose levels, the temperature during the sample period (16 to 18ºC) did not influence the health of striped bass juveniles (Brougher et al, 2005; Davis & Parker, 1990).…”

“…Usually, a fish infestation could be correlated with a low immune response caused by acute or chronic stress (Serradell et al, 2020). Stress that could also be correlated to different temperatures, as previously reported in this species (Araújo et al, 2021). Therefore, it will be interesting to test at different water temperatures throughout the year.…”

“…Therefore, a reliable culture methodology for the striped bass M. saxatilis entails establishing a useful routine method for determining the fish's health in captivity. Especially, when exposed to different temperatures throughout the year that could influence the immune responses (Araújo et al, 2021). Besides temperature, striped bass may be exposed to hypoxia events and the stresses of handling and transport, resulting in a disease outbreak (Serradell et al, 2020).…”

Striped bass (Morone saxatilis) is a species with high production potential for human consumption. However, like any other cultured species, they are prone to be exposed to adverse climate conditions, compromising their health status until a certain degree compromises the success of reaching commercial size. It is proposed that haematological parameters testing during the whole growing out season represents a useful tool to assess the overall fish health status. Information on M. saxatilis haematology is limited. Therefore, the present study aimed was to provide the haematological and blood chemistry values for commercial striped bass grow‐out. Fish from three different group sizes and under low sub‐optimal temperature (16 to 18°C) were sampled in correlation to copepods (Peniculus sp.) present attached to the fins. Thirty fish from each group (sized 0.17, 0.54 and 1.17 kg, corresponding to different ages and batches) were all sampled (blood and external parasites count) during the spring (5 June, June 12 and June 16, 2019). The results show that differences in blood parameters were only observed according to the weight of striped bass such as the haematocrit (HCT), haemoglobin, mean corpuscular haemoglobin concentration (MCHC), white blood cells (WBC) count, total protein, globulin, ratio A/G, cholesterol, triglycerides and glucose. In contrast, the copepods present showed a preference for the caudal fin of the striped bass, followed by the first dorsal and pectoral fin. The smaller fish (0.179 kg) were the most susceptible to Peniculus sp., compared to the largest fish (1.174 kg). So far, it can be concluded that at this stage, the copepod does not show any adverse effect on the fish health since the condition factor and blood parameters were statistically similar along with the different copepod infestation levels (intensity ranged from 7 to 109). However, this new copepod, here registered for the first time in the Morone saxatilis, was registered during the sunset to increase environmental temperature. Even if no signs of a harmful relationship between parasites between young and old organisms, it will be necessary to be further monitored. The copepod incidence and the blood parameters should be analysed along the year (different temperatures), aiming to detect any correlation to the copepods present or, in any case, the overall health status or another parasite present under the seabass culture conditions.

Long-chain polyunsaturated fatty acids (PUFA) are critical for reproduction and thermal adaptation. Year-round variability in the expression of fads2 (fatty acid desaturase 2) in the liver of European perch (Perca fluviatilis) in a boreal lake was tested in relation to individual variation in size, sex, and maturity, together with stable isotopes values as well as fatty acids (FA) content in different tissues and prey items. ARA and DHA primary production was restricted to the summer months, however, perch required larger amounts of these PUFA during winter, as their ARA and DHA muscle content was higher compared to summer. The expression of fads2 in perch liver increased during winter and was higher in mature females. Mature females stored DHA in their gonads already in late summer and autumn, long before the upcoming spring spawning period in May. Lower δ13CDHA values in the gonads in September suggest that these females actively synthesized DHA as part of this reproductive investment. Lower δ13CARA values in the liver of all individuals during winter suggest that perch were synthesizing essential FA to help cope with over-wintering conditions. Perch seem able to modulate its biosynthesis of physiologically required PUFA in situations of stress (fasting or cold temperatures) or in situations of high energetic demand (gonadal development). Biosynthesis of physiologically required PUFA may be an important part of survival and reproduction in aquatic food webs with long cold periods.
