“…Moreover, the observed higher WBC number at 31°C and 34°C after 6 weeks thermal exposure can be correlated with additional antibody demand that may help the fish to survive in adverse environmental condition. Similarly, RBC and WBC number were found to be increased with increased water temperature in striped catfish (24°C to 36°C) and common carp (20°C to 32°C) when reared for a period of one month (Ahmad et al, 2011; Islam et al, 2019).…”

“…Cell shrinkage and membrane blebbing are signs for apoptotic cells (Talapatra & Banerjee, 2007). Though a number of studies have been conducted for better understanding of physiological thermal stress responses of aquatic organisms (Ahmad et al, 2011; Cheng et al, 2013), the high temperature effects on blood profiles of red spotted grouper Epinephelus akaara , are not well studied. Analysis of blood profiles in response to thermal exposure is required to get a rapid feedback about the immune response of the stressed fish and thus will help to develop advance management strategies for the improvement of fish habitat in consideration of rising sea water temperature.…”

Rising of water temperature due to global warming is a great concern to aquaculturists and fishery biologists. Hence, the present study aimed to investigate the effects of high water temperature on juvenile red spotted grouper, Epinephelus akaara based on the evaluation of stress responses in blood. E. akaara juveniles were exposed to different thermal conditions (25℃, 28℃, 31℃, and 34℃) for 6 weeks following 2 weeks of acclimation at 25℃. Blood cell morphology and number were examined at three sampling points (2, 7, and 42 days) from a total of 180 fish. Major erythrocytic cellular abnormalities (ECA) observed in blood smears of thermally stressed groups (31℃ and 34℃) after 6 weeks were echinocytes, teardrop-like cells, swollen cells and vacuolated cells. Both red and white blood cell number (RBC and WBC) were significantly ( p <0.05) elevated in 31℃ and 34℃ group after 6 weeks thermal exposure. Differential leucocytes number showed significant increases in neutrophil (N) and decreases in lymphocytes (L) in the highest temperature (34℃). Different N:L ratio was observed at different thermal conditions which can be used as a reliable alternative to measure stress response. Taken together, these results suggest that higher temperature (31℃ and 34℃) can interfere the immune system of red spotted grouper by altering the blood cell morphology and number.

“…Similar phenomena were also observed in some fish under thermal stress. For examples, C. carpio gills revealed separation of epithelium from lamellae, lamellar fusion and swelling of the epithelial cells (Ahmad, Shah, Bhat, Bhat, & Balkhi, ). And flounder gill suffered the most serious damage, including highly severe epithelial lifting and edema, and desquamation and necrosis (Liu et al, ).…”

Olive flounder Paralichthys olivaceus is an important mariculture fish and cold stress limits to its growth and survival during winter. In the present study, the cold‐tolerant (CT) and cold‐sensitive (CS) flounder were defined after cold treatment (0.7 ± 0.05°C). Cold effects on histological and physiological and gene expression levels were analyzed. The correlation analyses between single nucleotide polymorphism locus (SNP) in hsp70, yb‐1 and hmgb1 and the trait of cold tolerance were performed. The results showed that flounder gill was obviously damaged after treatment and more serious lesions in some of the epithelial cell layers were observed in the CS group. ATP concentration and pyruvate kinase activity in the CT group were significantly higher than those in the CS group (p < 0.05). Expression levels of hsp70 and yb‐1 were both up‐regulated markedly after cold treatment (p < 0.05). Nine, twenty‐one and ten SNPs were screened from hsp70, yb‐1 and hmgb1 partial sequences, respectively. Among them, 3 SNPs in hsp70 and 2 SNPs in hmgb1 showed significant difference in the two groups. Allele G of the SNP 8 (locus 1797) in hsp70 was only observed in the CT group. In the SNP 7 (locus 725) of hmgb1, genotype TT and allele T, and genotype CC and allele C were associated with cold tolerance and cold sensitive, respectively. Furthermore, one haplotype (TTG) generated from SNPs of hsp70 gene among CT and CS individuals showed significant relationship with cold tolerance (p = 0.031). Two haplotypes (ATG) and (TCT) generated from SNPs of hmgb1 were significantly associated with resistance (p = 0.001) and sensitive (p = 0.002) in cold treatment, respectively. These SNPs, genotype, alleles and haplotypes of hsp70 and hmgb1 may be related to the cold resistance of flounder, and could be candidate markers potentially for further selective breeding.

“…The common carp Cyprinus carpio L. 1758 is currently considered one of the most ecologically harmful invasive species and is ranked among the eight most invasive fish taxa of the world by the International Union for the Conservation of Nature (Lowe et al ., ). It possesses multiple traits that contribute to its success as an invasive species, such as broad environmental tolerance, early sexual maturity, high reproductive capacity, short generation times, fast individual growth rates and a generalist diet (Schade & Bonar, ; Ahmad et al ., ). Its effect is mainly due to its ability to alter aquatic habitats through high levels of nitrogen excretion and disturbance of the bottom sediments of lakes and reservoirs where it has been introduced.…”

Common carp Cyprinus carpio possess multiple traits that contribute to their success as an invasive species. They have been introduced across the globe, and abundant populations can have numerous negative effects. Although ecological niche-based modelling techniques have been used to predict the potential range of C. carpio invasion in U.S.A., occurrence and abundance patterns have not yet been considered on a regional scale. In the present review new locations are documented, the status of the southernmost population has been studied and the probability of new lakes and reservoirs being colonized by C. carpio has been obtained and related to environmental conditions. The new localities for C. carpio have expanded its distribution westward, into the Andean Region, and present results from the South American southernmost population have shown a well-established population. Analysis of presence data provided two principal results: (1) the probability of a site being with C. carpio can be inferred using environmental variables and (2) the probability of a site being with C. carpio is a useful tool for the prediction of future invasions. Selective fishing on the Negro basin could constitute a potential mitigation measure, decreasing the abundance of the species and thus reducing the species' potential for southward expansion. These results reinforce the idea that artisanal fisheries, food production and conservation interests should be taken into account by local government management agencies in any discussion regarding the southern distribution of C. carpio in the near future.
