Atlantic salmon (Salmo salar), an important source of omega 3 long chain PUFAs, has a sizeable amount in international seafood trade because it is an abundant source of omega-3 long-chain PUFAs. Despite the fact that cooking fish to high temperatures alters its fat, protein, vitamin, and mineral content, cooked fish is preferred by consumers. The purpose of this research was to compare nutritional, physical and sensory properties of Atlantic salmon cooked in the oven, steamed and also a combination of the two cooking methods. Farmed Atlantic salmon was used to make steaks that were defrosted in the fridge the night before. Cooking methods applied were baking in the oven, steaming, and a combination of oven-baking and steaming. The results showed that the crude protein level of oven-baked salmon meat was greatest among all cooking methods. Heat treatment affected the fatty acid composition of Atlantic salmon flesh, as shown that the total saturated fatty acids of cooked fish groups were higher than those of raw salmon. It was determined that oven baking was the most effective heat treatment for maintaining all lipid characteristics of the meat, including the PUFA concentration and n-3/n-6 ratio. When EPA and DHA values of all cooking groups were compared, combination cooking group has lowest value than other cooking groups.","PeriodicalId":11439,"journal":{"name":"Ege Journal of Fisheries and Aquatic Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138999408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, liver, intestine, muscle, brain, heart, eye, spleen, gill, kidney, stomach, ovary and testis samples were taken from male and female brown trout and common carp, and total RNA was isolated from each tissue to synthesize cDNA from these tissues. Then, the transcript amounts of the gstr gene were determined by qPCR from all tissue samples. Gene structures, conserved gene synteny design, phyogenetic tree analyzes and similarity-identity ratios with other vertebrates were determined. When the transcriptional differences between male and female tissues for the brown trout gstr gene were examined, it was seen that the intestine, gill, kidney, stomach, muscle and gonads were significantly higher in male fish (p<0.05), but the differences between other tissues were not statistically significant. It has been determined that the highest gene expression was liver (p<0.05) and brain, eye, spleen, kidney, heart and spleen tissues have significantly lower gstr gene expression than other tissues in both male and female in common carp. In addition, the in-silico analysis determined that the brown trout gstr gene shared the highest similarity and identity ratio with rainbow trout, and the common carp gstr gene shared the highest similarity and identity ratio with goldfish.","PeriodicalId":11439,"journal":{"name":"Ege Journal of Fisheries and Aquatic Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138995954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sea bass fry with an average body weight of 1.0 ± 0.03 g were stocked in 120 liter tanks in triplicate after their adaptation to freshwater. The feeds used in the study had different protein/similar fat content. Accordingly, the experimental groups were named as 45CP (45% CP / 18% CF), 50CP (50% CP / 18% CF) and 55CP (55% CP / 18% CF). At the end of the experiment, the highest body weight gain was 5.84 ± 0.03 g in the 55CP group, while the other groups were 5.73 ± 0.09 g (45CP) and 5.8 ± 0.08 g (50CP). SGR rates were similar for all three groups and there was no statistical difference between the groups (P>0.05). SGR values of the groups were calculated as 1.94 ± 0.04 (45CP), 1.89 ± 0.01 (50CP), 1.91 ± 0.02 (55CP), respectively. There was no statistical difference between the 45CP and 55CP groups, while the 50CP group showed a statistically lower FCR rate than the other groups (P<0.05).

A total of 1.530 specimens were captured, representing seven families and 11 species (2 non-native, 1 introduced, and 8 native species). Total fish abundance and richness were higher at the littoral than at the limnetic zone, but no seasonal variation was observed. Non-native fish species, Coptodon zillii, was the most abundant in the littoral zone, followed by species of Mugilidae. The abundance of the two endemic fish species (Capoeta aydinensis and Ladigesocypris irideus) was relatively low in both habitats. Shannon-Wiener diversity index and evenness did not vary seasonally and spatially. Fish abundance and richness were significantly and positively correlated with chlorophyll-a and macrophyte coverage while negatively correlated with depth. Spearmen’s Correlation analysis revealed that native fish species show a relationship with the chemical parameters of the water, while C. zillii showed a distribution related to depth and macrophyte density. Both anthropogenic activities and the presence of non-native fish may affect the distribution and abundance of endemic fishes.","PeriodicalId":11439,"journal":{"name":"Ege Journal of Fisheries and Aquatic Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138997135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this research is to improve a record of diplozoid species occurrence in C. aydinensis, an endemic fish species by collecting data from a previously unexplored locality situated in a different geographical region of Türkiye. A total of 187 individuals of C. aydinensis were collected by using fishing nets from October 2019 to July 2020 and examined for the presence of diplozoid species. Only one species of diplozoid has been recorded, known as Paradiplozoon bliccae (Reichenbach-Klinke, 1961), which has been identified morphologically and confirmed through molecular analysis. The nucleotide sequences of the parasite's nuclear internal transcribed spacer (ITS2) gene marker were determined as well as phylogenetic analyses by using Bayesian inference (BI) analyses. On the basis of the molecular findings, the morphological identification of the diplozoid parasite species was confirmed. Of 187 fish sampled, 27 were infected with 117 P. bliccae, representing an abundance of 0.6, a mean intensity of 4.3 and a prevalence of 14.4%. The prevalence and mean intensity of infection were based on the season and sex of the host. The highest values of infection for prevalence, mean intensity and abundance were found in summer. Meanwhile, mean intensity and abundance of P. bliccae were higher in males, the prevalence was higher in females. To our knowledge, the present study is the first ichthyoparasitological study of C. aydinensis in Köyceğiz lake, near the province of Muğla in Türkiye. Furthermore, sequence data of P. bliccae from fish hosts in this locality were reported to GenBank for the first time as part of this study.
