This study aimed to carry out a comparative evaluation of the hematological profile (erythrocyte count, hemoglobin concentration, hematocrit, and Wintrobe index parameters such as mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration), in addition to certain biochemical parameters (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, serum total protein, albumin, glucose, total cholesterol, and triglycerides), in the Italian mullet Mugil cephalus (Linnaeus 1758) and the Turkish mullet Chelon auratus (Risso 1810). Accordingly, two groups of fish were used in this study: 30 flathead grey mullets, M. cephalus, caught in Lake Faro, Italy, and 30 golden grey mullets, C. auratus, caught in the estuarine channel system of Köyceğiz–Dalyan, Turkey. Statistical evaluations (unpaired t-test) revealed that there were no significant differences in weight or total length values between the two mullet groups. However, the differences between all the evaluated blood parameters (except alanine aminotransferase) between the Italian and the Turkish mullet were significant (P < 0.0001). The present study demonstrated that there were significant hematological and biochemical differences between the Italian (M. cephalus) and the Turkish (C. auratus) mullet. Our findings also contribute to expanding the knowledge on the hematology and biochemistry of two different species of mullet originating from two different habitats. Since the evaluation of blood parameters represents an essential tool in examining the effects of environmental conditions on fish physiology and, consequently, on fish health status, further research in this field is encouraged and would be very useful.

Blood parameter assessments of fish may be used as quick tools for diagnosing health status. The aim of this research was to undertake a comparative study of hematological and biochemical parameters of Italian and Turkish farmed rainbow trout Oncorhynchus mykiss (Walbaum, 1792) to establish baseline values in relation to different areas. Forty Italian trout (32.59±0.25 cm total length, 397.40±6.49 g weight) and forty Turkish trout (33.00±0.24 cm total length, 385.70±3.50 g weight) were examined. Statistical analysis (unpaired t-test) showed no significant differences in weight, length and condition factor between two farmed trout groups. Statistically significant differences (P < 0.05) were found in some hematological and biochemical parameters between Italian and Turkish farmed rainbow trout. Our findings shown that in Italian farmed rainbow trout Red blood cell (RBC), Hematocrit (Hct), Cholesterol and Total protein values were significantly lower than Turkish trout, instead Mean corpuscular volume (MCV), Mean corpuscular hemoglobin (MCH), Mean corpuscular hemoglobin concentrations (MCHC), Glucose, Triglycerides and Serum albumin shown significantly higher values. No statistically significant differences were found for White blood cell (WBC) and hemoglobin (Hgb). The results of this study contribute to knowledge of the baseline of hematological and biochemical parameters of rainbow trout farmed in two different habitats suggesting that blood parameters could be an important value in monitoring environmental conditions on fish physiology and fish culture management.

Different feeding habits may affect the blood parameters in fish species of the same family, even if they live in the same marine habitat. The aim of this study was to compare some haematological and biochemical parameters of two marine fish species of the same family, the saupe Sarpa salpa (Linnaeus, 1758) and the common two-banded seabream Diplodus vulgaris (Geoffroy Saint-Hilaire, 1817), and to establish the similarities and differences between these species. For this purpose red blood cells (RBC), haemoglobin concentration (Hb), haematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), glucose (GLU), triglycerides (TRIG), cholesterol (CHOL), serum total protein (TP), albumin (ALB), globulins (GLO), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) were determined for 30 fish from each species. Statistical analysis showed significant differences in some haematological and biochemical (RBC, Hb, Hct, TP, ALB, GLO, AST, ALT, ALP and LDH) parameters between the two species. Lower values of RBC, Hb and Hct were found in S. salpa in comparison with D. vulgaris. These differences could be attributed to the feeding behavior, life style and habitat adaptation of the different fish species of the same family and contribute to knowledge of reference values of blood parameters in Sarpa salpa and Diplodus vulgaris. No significant differences were found in MCV, MCH, MCHC and GLU, TRIG, CHOL.

This study is aimed to assess the effects of pomegranate seed oil (PSO) supplementation on growth performance, some hematological, biochemical and immunological parameters, and disease resistance against Yersinia ruckeri in cultured rainbow trout Oncorhynchus mykiss (Walbaum, 1792). 240 fish in total were randomly assigned into four triplicate groups (20 fish/per aquarium) corresponding to four dietary treatments: control (PSO0; no addition of PSO), 0.5% (PSO5), 1.00% (PSO10), and 2.00% (PSO20) of PSO, respectively. After the 60 day-feeding trial, fish blood samples were collected and compared. Statistical analysis (one-way ANOVA) showed a significant (P < 0.05) effect of PSO on red blood cell count, hemoglobin concentration, mean corpuscular volume, mean corpuscular hemoglobin concentration, cholesterol, aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase parameters in PSO5 and PSO10 with regard to control. Moreover, a pronounced (P < 0.05) increased in weight gain, growth and feed conversion was found in fish fed with PSO supplemented diets. After the feeding trial, fish were challenged with Y. ruckeri and survival recorded for 20 days. Cumulative survival was 45.10% in fish fed with the control diet, whereas in fish fed with PSO5, PSO10, and PSO20 supplemented diets, survival was 58.82, 56.86, and 56.86%, respectively. In conclusion, dietary administration of PSO induced a reduction in mortality of rainbow trout infected with Y. ruckeri, intercalary significant differences occurred on growth performance and some blood values among treated groups. These positive effects of PSO could be considered for new applications in aquaculture.
Effects of heavy pollution in different water bodies on male rainbow trout (Oncorhynchus mykiss) reproductive health

This research aimed to investigate the influence of heavy metals on the reproductive health of rainbow trout (Oncorhynchus mykiss) captured from two locations, Verinag (S1) and Panzath (S2). Sixty (n. 60) mature rainbow trout samples (30 from each site) with body weights ranging from 400 to 650 g were collected from Verinag hatchery, which was less polluted (S1), and Panzath hatchery, which was more polluted (S2). The findings revealed significant differences between the two sites, S1 (less polluted) and S2 (more polluted), as well as significant variations within the tissues. Iron (Fe) and Zinc (Zn) were found to be highest in sampling water as well as in fish tissues sampled from S2 sites. Similarly, concerning S1 captured fishes, histopathological examination of testes from S2 captured fish was found. Testicular abnormalities that included disorganization of the seminiferous tubules, reduction in the number of germ cells (sperm cells, spermatozoa), vacuolization, and large empty areas in the seminiferous epithelium were found. In testicular cells, the frequency of apoptotic cells collected from S2 water increased significantly (P < 0.05). SOD, catalase, and glutathione peroxidase activity increased in S1 captured fishes but decreased in S2 captured fishes. MDA levels gradually increased in S2 captured fish, and the degree of heavy metal stress was positively correlated (P < 0.05). In male rainbow trout, testosterone and 11-ketotestosterone levels increased substantially in S1 captured fishes. While the fatty acids of testes in S2 fishes decreased with respect to S1 fishes. In conclusion, S2 captured fish suffered more damage due to heavy metals including cellular damage, apoptosis, oxidative damage, and altered steroid hormones when compared to fish from S1 waters.

The purpose of this study was to examine various lipid classes as well as the protein content in rainbow trout ovaries. A total of 80 samples of Oncorhynchus mykiss (Walbaum 1792) were collected from Kokernag and Verinag hatcheries (Jammu and Kashmir, India) between 2017 and 2019. The mature stage in female fish had the highest gonadosomatic index (GSI) and minimal GSI in the spent stage. Higher lipid content of the ovary was reported during the mature stage (36%), as compared to other pre-breeding stages. Similarly, lipid classes also showed fluctuation during the development of the ovary. The lipid classes, i.e. glycolipids, free fatty acids, cholesterol and triglycerides, had a higher content in the mature stage, while the phospholipid content was higher in the mature stage. The protein content was also higher in the mature ovary than in the other developmental stages. The study provides reference values for various biochemical parameters in rainbow trout that could be useful for population monitoring programs and for the development of diets and management methods for fish production under controlled conditions.
