Depending on this use, non-target organisms are also affected apart from target organisms. Cyfluthrin is a synthetic pyrethroid pesticide used in agriculture, domestic and veterinary medicine against insects. It may also affect non-target aquatic organisms as a result of mixing with aquatic ecosystems. This study was aimed to investigate the effect of cyfluthrin on freshwater mussels, one of the aquatic invertebrate species, with hemocyte parameters. Total hemolymph counts, hemolymph cell morphology, and differential hemocyte counts were performed from hemolymph taken from mussels exposed to different cyfluthrin doses exposures for 24 and 48 hours. Compared to the control group, the total hemocyte counts of the experimental groups were found to increase in 24h and decrease in 48h significantly (p<0.05). In the examination of hemocyte morphologies, granular, semi granular, and hyalinocyte cells were observed. Similar values of differential hemocyte counts were found both 24 and 48h exposure times. As a result, in aquatic toxicology studies, besides total hemocyte count, analysis of hemocyte morphologies and differential hemocyte counts are found to be good biomarkers.","PeriodicalId":11439,"journal":{"name":"Ege Journal of Fisheries and Aquatic Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90872835","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}

LSE results show a gradual increase of Plecoptera and a gradual decrease of Trichoptera and no such variations in Ephemeroptera. Variations in mesohabitat richness were highest in the run (38.38%) and it was lowest in silt (0.5%). To compare the taxa composition in Western and Eastern Ghats taxa, five different types of river basins were classified. The species richness and abundance were higher in Tampiraparani East flowing and Vamanapuram River basin communities (Western Ghats) than in the Eastern Ghats and this shows mega diversity of Western Ghats compared to the Eastern Ghats. The results of both cluster and ordination analysis also strongly support the discrimination between Western and Eastern Ghats diversity and distribution of EPT taxa.","PeriodicalId":11439,"journal":{"name":"Ege Journal of Fisheries and Aquatic Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73376190","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 study was designed two different pH levels (high 7.98±0.2 and low 6.01±0.1), salt (6g/L), and ceramic ball (10g/l) addition and fish stock density to be 62.3 kg/m3. The trial tanks were mounted on a vehicle to represent actual transport conditions. Fish were sampled every hour for gill histology. As a results, the lowest ammonia value was determined as 1.98 mg/L in the ceramic ball. The highest ammonia value in the high pH group was 2.83 mg/l. When the gill tissues of the fish were examined, the significant differences observed were oedema and epithelial lifting in the control and high pH groups. Hyperplasia, epithelial lifting, and multiple deformations were observed in all the experimental groups except the ceramic ball group. This study showed that based on the histological results of the gills and the stability of the pH levels of the water and the effect on the reduction of the ammonia value of the water, that the ceramic balls are particularly useful for the transport of live fish.","PeriodicalId":11439,"journal":{"name":"Ege Journal of Fisheries and Aquatic Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77401225","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}

Protein extraction was performed at different concentrations (0.5%, 1%, 1.5% and 2%) and times (30 minute, 1 hour and 4 hours). The moisture, crude protein, lipid and crude ash contents of trout viscera used as raw materials, in the study, were respectively found as 60.26±0.78%, 12.18±0.21%, 31.18±0.36% and 1.33±0.07%, while these values in smoked trout trimmings were determined as 54.53±0.93%, 18.39±0.13%, 17.71 ± 1.06% and 8.50±0.13%, respectively. Following the conclusion of the study, protein content (g protein/100 g waste) and Protein Recovery Rate (PRR, %) in liquid protein hydrolysate extracted from trout viscera and smoked trout trimmings were found to be significantly affected by enzyme type, enzyme concentration, and extraction time. The results showed that the flavourzyme, followed by the protamex, produced the highest protein content (g protein/100 g waste) and PRR (%) in the liquid protein hydrolysate extracted from trout viscera.

It is important to determine these effects to make the right decisions in fisheries management. This study aims to assess the fishing capacity, technical efficiency, scale efficiency, and capacity use in a specific subset of Rapa whelk fishers, those in Turkey's Black Sea. Economically efficient and inefficient boats were also compared in the study. The data obtained through face-to-face interviews with 452 boat owners constitute the main data of the study. Data were collected about the economic efficiency of the boats for one year. While economic efficiency ranged between 0.27 and 1, the average value was found to be 0.60. It was concluded that the age of the owner, the education period, and the length of the fishing boat positively affected economic efficiency (p<0.05). In the boats studied, technical efficiency scores were greater than economic efficiency scores. This suggests that rather than technical information, fishers require information on selecting the optimum input combination at the data cost level.","PeriodicalId":11439,"journal":{"name":"Ege Journal of Fisheries and Aquatic Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83465878","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, the fluctuating asymmetry levels of the otoliths of four Alburnus species (A. chalcoides (Güldenstädt, 1772), A. tarichi (Güldenstädt, 1814), A. escherichii Steindachner, 1897, and A. mossulensis Heckel, 1843) found in Turkish inland waters were investigated. A total of 160 fish were collected in the Turkish inland waters. The fluctuating asymmetry level was calculated for the width and length characters of the asteriscus. Alburnus species, which were examined in the present study, were divided into four total length classes and fluctuating asymmetry of otolith was evaluated according to both the total length classes and species. There was significant difference between the right and left asteriscus otolith measurements for A. escherichii (P<0.05). Besides, there were no significant differences between females and males’ otoliths measurements of the species (P>0.05). The highest and lowest asymmetry levels in the otolith length and otolith width were calculated in the A. escherichii among the Alburnus species. However, the highest and lowest asymmetry levels in otolith length and otolith width were calculated in the A. mossulensis among the total length groups of the Alburnus species. In this study, it was determined that the fluctuating asymmetry level varies according to different fish species and habitats.","PeriodicalId":11439,"journal":{"name":"Ege Journal of Fisheries and Aquatic Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88524111","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}
