However, studies conducted in recent years have suggested that the species described in southeast Anatolia and Iran belong to different genera. The results and recommendations of these studies were evaluated. On the other hand, in the scope of this study, the taxonomic status and length-weight relationship of several Petroleuciscus ninae populations in Western Anatolia were evaluated. The morphological comparisons revealed that Tahtalı Reservoir, Küçük Menderes and Sarıçay rivers, and Acıgöl Lake`s Petroleuciscus populations recorded as Petroleuciscus smyrnaeus in all previous studies belong to P. ninae which was known only from the type locality Akçay Stream. In addition, the length-weight relationship of P. ninae in the lakes Akgöl and Belevi, Lake Acıgöl, stream Akçay, Sarıçay River, an inflow of Yenişehir Reservoir and inflow of Tahtalı Reservoir were studied. The following research considers some first records and comprehensive information on the length-weight relationship of P. ninae in the Western Anatolia water resources. In study, the constant b changed from 3.101 to 3.389 (Akçay Stream) in all the sampling locations. It is expected that the results of this research might support the conservation of this species and contribute knowledge of its taxonomic status.","PeriodicalId":23978,"journal":{"name":"Turkish Journal of Fisheries and Aquatic Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136183271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Incremental levels of BSF larval meal (BSFM, 0.5 to 5%) were used to partially substitute the use of fishmeal (FM) in the diet. In addition, next group of dietS were designed by using incremental levels of BSF larval oil (BSFO (0.5 to 5%) with 0.5% BSFM as a reference to partially and completely replace the use of fish oil (FO) within the diet. Ten dietary treatments were evaluated as four replicates in 40 Hapa ponds assigned randomly. Shrimp of initial mean weight of 0.97 g were fed by hand over 90 days with feed intake based on an FCR of 1.5 and all parameters recorded to determine response. Inclusion of up to 5% of both BSF meal and oil improved performance with respect to growth rate and feed utilization efficiency FCR. Total hemocyte counts and lysozyme activity reflected these trends displaying advantages of BSF diet groups compared to the basal fed group of L. Vannamei. After the growth trial, a disease challenge test was undertaken using an infection model with Vibrio harveyi at a concentration of 105 CFU shrimp-1 under controlled laboratory settings. As such, several indices of health status were recorded that included hemocyte counts, lysozyme activity as well as histopathology of the hepatopancreas that is a prime indicator of the progression of disease and a reflection on health status. Insect meal and oil inclusions increased survival from 40% to 60 - 80% and in accordance, raised the immune response and improved histopathological profiles of hepatopancreas tissues.","PeriodicalId":23978,"journal":{"name":"Turkish Journal of Fisheries and Aquatic Sciences","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135110417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Pro08 and Pro06 strains were identified as Bacillus pumilus and Lysinibacillus macroides, respectively, by 16S rRNA sequencing. The Pro08 showed a high multi-specific antibiosis efficiency score and a high spectrum of antibacterial activity. The Pro08 showed more pH and bile tolerance than the Pro06. In the in vitro adhesion study, Pro06 exhibited more cell-surface hydrophobicity while Pro08 showed a better capability of auto and co-aggregation along with biofilm-forming ability. The Pro08 significantly adhered to mucosal-surfaces. The Pro08 showed positive protease, amylase, lipase, and cellulase activity, the Pro06 was positive only for lipase activity. The radical-scavenging activity was significantly higher in Pro08 than Pro06. The Pro06 was resistant to oxacillin antibiotics, while pro08 was susceptible to all the tested antibiotics. Both strains were non-haemolytic and were non-toxic to fish embryos. No mortality or clinical-signs were observed during the challenged study in L. catla.

Total bacterial load on the medium and bacteria species were identified in terms of their morphological characteristics using the spread plate method. Bacteria that emerged at different times in the trial sets were identified as Edwardsiella tarda, Salmonella sp., Aeromonas hydrophila, Pantoea sp., Citrobacter youngae, Serratia ficaria and Citrobacter freundii. The total bacterial load in both freshwater and seawater environments in both lamp groups showed a decrease compared to the control group. With this, the conventional lamp model was more effective on the total bacterial load in the samples taken during the trial. Although all bacteria were inactive in both lamp groups, Serratia ficaria bacteria were not eliminated in the seawater environment.

Ingested prey organisms were identified to the lowest reliable taxonomic level. The biotic indices: vacuity index (VI), frequency of occurrence (F), abundance (Cn), index of importance (PV), Shannon`s diversity index (H`), and equitability index (Eh) were calculated. A total of 18 prey categories and 1144 individual prey were identified in the fish diet, dominantly aquatic macroinvertebrates. There were no significant difference in diet composition between sampling months as well as 0+, 1+, and 2+ age groups (both 3+ and 4+ had one individual). Only eight individuals were found with empty intestines, thus VI was low (2.9). In average, each fish had 4.1 prey items in their intestines. For whole sample, H′ was 1.84 and Eh was 0.64. Trichoptera, Ephemeroptera, and Gastropoda were the most frequent, dominant, and abundant.

However, the defects of natural fish AMPs, such as their high hemolytic activity and low stability, hinder their application. Therefore, many scientists have tried to optimize the sequence and structure of fish AMPs to meet actual clinical needs. In addition, as the most promising alternative to antibiotics, fish AMPs have good application prospects in animal husbandry, food, biomedicine, and other fields. Many fish AMPs are being researched and developed by scholars around the world.

The main surface current circulation has a cyclonic nature, and its impact on the routes of drifting objects is clearly seen. The results of the study are useful for predicting the trajectories of drifting objects and the proposed method and calculations can be roughly used for drifting trajectory prediction. The advantage of this method is that it is user-friendly and provides many tracks in a minute.

This study investigated the kinetics of microwave drying and rehydration of blue mussels (Mytilus edulis) in the range of 140 - 350 W power levels and 20 - 40°C temperatures, respectively. The drying data were utilized to calculate effective diffusivity coefficients (Deff) and activation energy (EA), while rehydration rates and time were also determined. Mathematical modeling was employed to describe the drying and rehydration processes, and the performance of different models was evaluated. The drying process took between 13 - 4.5 minutes, while rehydration was concluded within 360 - 480 minutes. The Deff values ranged from 1.22 - 3.91×10-7 m2/s, and the EA was calculated as 11.417 kW/kg. Rehydration rates resulted in 0.000061 - 0.000126 g/g×min at the highest 40°C and 0.000018 - 0.000032 g/g×min at the lowest 20°C. The drying and rehydration processes were best described by the Alibas model among 11 models and the Two-Term Exponential model among 2 models, respectively.

Asian seabass liver lipase was therefore subjected to fractionation with the aqueous two-phase system (ATPS) to remove proteases from lipase. ATPS was carried out using various salts and polyethylene glycol (PEG) having various molecular weights at different concentrations. The concentration of 20% ammonium sulfate (w/v) and 50% PEG-6000 (w/w) could reduce protease by 85%. Lipase-rich fraction showed a specific activity of 68 U/mg protein, purification fold of 9, selectivity of 167, and yield of 48%. When pulse electric field (PEF) was treated Asian seabass fish skin was defatted, and the acid-soluble collagen was extracted and characterized. The ATPS fractionated lipase could remove more than 92% of lipid contents. Polyunsaturated and monounsaturated fatty acids were mainly eliminated. The extracted collagen from defatted skin showed typical type Ⅰ collagen with negligible degradation. FTIR spectra substantiated the presence of amide groups in resulting skin collagen. Thus, the fractionation of Asian seabass liver crude extract with ATPS could significantly remove the contaminated proteases.
