Two hundred fishes were randomly stocked in five treatments each with four replicates in 72 litre tanks. Five treatments namely T1, T2, T3, T4 and T5 were maintained with water temperature of 16°C, 20°C, 24°C, 28°C and 32°C respectively. The hemoglobin, hematocrit and Total Red blood cells increased with the increase in acclimation temperature. Whereas, total leukocyte count showed an inverse trend. Differential leukocyte count showed significant (P<0.05) increase in neutrophil and drop in lymphocyte count. Minimum glucose level was observed at T3. Total-protein, albumin and globulin increased with the increase in temperature. whereas, Triglycerides and cholesterol showed inverse trend. The histological examination revealed that gills and liver were adversely affected below T3 and above T4, with most marked changes noticed at 32°C (T5). This fish displayed adaptive physiological changes to counteract the effect of temperature variations. The findings of this study indicate that C. carassius can be reared between 24°C to 28°C and is important for understanding how fish adapt to temperature changes, especially in context of climate change.","PeriodicalId":23978,"journal":{"name":"Turkish Journal of Fisheries and Aquatic Sciences","volume":"25 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://doi.org/10.4194/trjfas26088","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147888971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Peak values were observed in March, with females showing a GSI of 21.48±2.69% and an HSI of 8.03±1.83%, and males at 1.37±0.38% (GSI) and 4.68±0.23% (HSI). Six hormonal treatments (CPG, HCG, Ovupin, and combinations) were tested. Ovulation rates ranged from 47% to 95%, with Ovupin inducing the shortest ovulation period (5.48 hours) and HCG the longest (7.18 hours). Fertilization rates varied from 65.74% to 93.48%, with CPG (T1) achieving the highest fertilization (93.48±5.83%) and hatching rate (89.36±7.26%). Larval survival rates after 48 hours were highest with CPG (73.9±3.79%) and lowest with HCG (32.5±2.14%). Optimal water quality parameters contributed to successful breeding.

Therefore, locally available canola meal, feather meal, blood meal and poultry by-product meal were evaluated on their suitability for feeding rainbow trout. Fish growth performance and apparent digestibility coefficients (ADCs) of nutrients were investigated for three casein-based fish meal-free diets, a practical feed including 10% spray-dried blood meal, 22% poultry by-product meal, 10% feather meal (GOLDMEHL®), 10% canola meal and 15.5% wheat flour in comparison to a commercial diet containing fish meal. The diets were allocated to aquaria in three replicates arranged in a random-block-design. Findings of the present study illustrated that growth performance remained unchanged (p>0.05) among fish fed fish meal-free diets and the commercial one. Formulating aquafeed using properly processed local feed ingredients such as poultry slaughterhouse by-products, canola meal, and crystalline amino acids can provide a sustainable solution to meet the feed requirements of the growing aquaculture industry on a regional scale. This research shows the potential for using locally available resources in aquafeed manufacturing.","PeriodicalId":23978,"journal":{"name":"Turkish Journal of Fisheries and Aquatic Sciences","volume":"36 12","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139167195","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}

Ultrasound Assisted Enzymatic Extraction (UAEE) and Microwave Assisted Enzymatic Extraction (MAEE) were performed to enhance degree of hydrolysis (DH), ACEi activity, and peptide yield (PY). The ACEi peptides were examined for stability during thermal processing, varied pH treatments and in vitro gastrointestinal digestion. Peptides were stable at different temperatures (25, 37, 55, 75, and 100°C) except at 121°C which reduced their stability by 7%, 6.9% and 2.2% in UAEE, MAEE and Non-Assisted Enzymatic Extraction (NAEE) peptides, respectively. Similarly, peptides retained ACEi at pH 2 to 8 and subsequent reduction at pH>8. In vitro digestion studies showed stability of all peptides to GI digestion at 0.05% pepsin, 0.05% trypsin, 0.05% chymotrypsin and the combination of 0.025% trypsin and 0.025% chymotrypsin except MAEE peptides showing less stability with pepsin (0.05%). Therefore, it is concluded that these ACEi peptides derived from rohu fish waste, stable to heat, pH and gastrointestinal enzymatic action, can be used as ingredient in functional foods, which undergo thermal processing and digestion.","PeriodicalId":23978,"journal":{"name":"Turkish Journal of Fisheries and Aquatic Sciences","volume":"226 ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139171384","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}

Response surface methodology was applied to optimize the culture conditions for enhancing antibacterial activity of the strain. The optimization was carried out using Box-Behnken design experiment to determine the optimum carbon and nitrogen sources in order to produce maximum antibacterial activity. The optimum media with high antibacterial activity was marine broth with the addition of carbon and nitrogen concentration source of sucrose 2.15 % and peptone 1.08%, respectively. In addition, the optimum temperature was 31.18oC. The antibacterial activity response was predicted using a statistical model and compared to the activity in the experiment.

Vaccines are widely regarded as the safest and most effective methods for preventing WSSV, and some main envelope proteins have showed this potential. In order to combine the antigenicity of these proteins together for better vaccine performance, in this study a strategy commonly used in vertebrates was tried in shrimp. The dominant epitopes of five envelope proteins VP19, VP24, VP26, VP28 and VP41A were predicted and combined for tandem epitope vaccine design by bioinformatics methods, the designed vaccine gene was chemically synthesized and expressed in Escherichia coli, then the recombinant peptide was purified for function evaluation in shrimp. The results showed that the designed peptide had good flexibility, hydrophily and antigenicity with all the epitope regions accessible; the synthesized gene was linked with the tag sequence and successfully expressed in BL21(DE3), and the purified fusion peptide showed a positive effect in WSSV prevention. This research provided a promising method to design vaccines against WSSV, and further work in genetic engineering should be done so as to make it operable for application in shrimp farm.","PeriodicalId":23978,"journal":{"name":"Turkish Journal of Fisheries and Aquatic Sciences","volume":"9 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136157271","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}
