Five isonitrogenous and isocaloric dietary treatments: T1, T2, T3, T4 and T5 were prepared by supplementing SFM at 0%, 25%, 50%, 75% and 100% respectively and fed to fish (4 ± 0.07 g) in triplicates. The growth performance and feed consumption in O. niloticus was significantly (p < 0.05) improved and body indices was significantly reduced in groups fed with T1 (control), T2 and T3 however, survival rate was remained unaffected among all dietary treatments. Significantly increased whole-body protein, serum total protein and albumin content was found in groups fed with T1 (control), T2 and T3, compared to T4 and T5 groups whereas, whole-body lipid content was significantly elevated in T5 group. In contrast, serum glutamic-pyruvic transaminase (SGPT) and glutamic-oxalacetic transaminase (SGOT) activity was significantly elevated in groups fed with T4 and T5. Additionally, serum triglycerides and cholesterol level were significantly increased in group T1 compared to other groups however, glucose and creatinine were not affected by dietary treatments. Uran`s pooled score for intestinal histology was significantly increased in SFM supplemented treatments as compared to control group. In conclusion, replacement of SBM with SFM up to 50% is possible without negative impacts on growth performance and health status of O. niloticus.","PeriodicalId":23978,"journal":{"name":"Turkish Journal of Fisheries and Aquatic Sciences","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47401702","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}

Here, we showed two species representing two diverse types of spawning behavior, having two distinct GC proliferation and spawning patterns. During July, a single peak spawning season for rohu was recorded with the highest GSI (female: 19.5±1.29 and male 4.2±0.24), which is the peak monsoon time in Eastern India. However, two peak spawning seasons were marked in tilapia during the pre-monsoon (April) and post-monsoon (October) period with GSI values of male: 0.9±0.21, female: 3.9±1.32 and male: 1.1±0.3, female: 4.4±1.1 respectively. Gonadal histology in synchrony with GSI provides insights into the effects of various seasonal climate changes on the reproductive status of fish. Further, GC ultra-structure revealed various development stages in rohu and tilapia in different seasons using a scanning electron microscope. Here, comparative models were proposed for GC proliferation and maturation during different parts of the year in rohu and tilapia that may be used to plan breeding programs and hatchery management of these two species.","PeriodicalId":23978,"journal":{"name":"Turkish Journal of Fisheries and Aquatic Sciences","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41470397","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 result found that increasing temperature and time of SV accelerated protein degradation, both myofibrillar protein and connective tissue. This affected to the lower water-holding capacity (WHC) and shear force of samples treated with severe SV conditions (S6-45 and S6-60) (P<0.05). SV technique may less contribution to the flavor formation, particularly lipid oxidation products, since there were no differences in total volatile base nitrogen (TVB-N) content and thiobarbituric acid reactive substances (TBARS) value among all samples (P>0.05). However, SV cooked samples had higher sensory scores than control, both at day 0 (before storage) or throughout the storage time. This suggested the potential to improve consumer acceptability by this technique.

Results showed that the stability of housekeeping genes were various in different tissues and the newly identified housekeeping genes were likely more stable than that of commonly used. In conclusion, the expression stability of housekeeping genes showed a tissue-specific manner, and the conserved oligomeric Golgi complex subunit 5 (cog5) and peroxisomal biogenesis factor 14 (pex14) could be universally used as appropriate housekeeping genes across different tissues in hybrid grouper.

SKJ fishery data from Iranian purse seiners and multisatellite remote sensing data were used for hotspot habitat modeling from 2010 to 2018. Spatial and temporal variables were the most important predictors in the generalized additive model (GAM), and 58.6% of the variance was explained. In the MaxEnt model, sea surface temperature (SST), eddy kinetic energy (EKE), and sea surface height (SSH) were the most important predictors of SKJ hotspot habitat suitability in the tropical Indian Ocean between 2°S and 2°N. Furthermore, of the total studied area in the Indian Ocean defined as optimal habitat (habitat suitability index>0.6), 6.8% and 5.3% exhibited ordinary habitat suitability (AUC=0.934, P<0.01) and hotspot habitat suitability (AUC=0.952, P<0.01), respec tively. Iranian purse seiners are distributed mainly in tropical areas, and in the present study, SKJ habitat was affected by environmental variables, as determined using multisatellite remote sensing data.
