Fish were assigned in three groups: control (21 days in freshwater), lufenuron (exposed for 21 days) and flonicamid (exposed for 21 days). After 21 days, all fish were subjected to 15 g/l saltwater for further 4 days. Plasma glucose, cortisol, sodium, potassium, chloride, calcium and phosphorus levels were monitored 0, 24, 72 and 120 h after saltwater exposure. Type of pesticides and time of salt water exposure had interaction on plasma glucose and cortisol levels. These two stress indicators were increased significantly in all groups after saltwater exposure. The cortisol elevation continued until 72 h after salinity challenge and then decreased significantly after 120 h salinity exposure in all treatments. Plasma glucose level showed fluctuation during saltwater exposure. It was increased after 24 h saltwater exposure, then decreased after 72 h and again it was increased after 120 h salinity challenge. Increased plasma sodium showed significant elevation along with elongation of saltwater exposure. Pesticide exposure significantly affected plasma chloride levels as the flonicamid group had significantly lower chloride compared to the control and lufenuron groups. Plasma chloride showed significant elevation along with elongation of saltwater exposure. Pesticide and time of salinity challenge had interaction on plasma calcium levels as 24 h after salinity challenge calcium level of pesticide groups increased significantly. Along with elongation of saltwater exposure, calcium level of pesticides treatments decreased but it higher than the pre salinity challenge. Plasma phosphorus level increased 24 h after saltwater exposure and decreased along with elongation of saltwater exposure. In conclusion, lufenuron and flonicamid induce stress and alter gill function and blood ionic homeostasis during saltwater exposure.","PeriodicalId":36975,"journal":{"name":"International Journal of Aquatic Biology","volume":"10 1","pages":"195-201"},"PeriodicalIF":0.0,"publicationDate":"2019-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80034116","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 present study investigates the possible effects of Florfenicol on cutaneous mucus immune parameters and immune related genes expression in Danio rerio . After two weeks adaptation, fish were stocked in experimental units at density of 20 fish per aquaria and fed with experimental diets containing 0, 10, 30 and 50 mg/kg FF per for 11 days. Evaluation of immune parameters at the end of trial showed that the control group had a significantly lower level of lysozyme activity when compared with those treated with antibiotic. However, the skin mucus total immunoglobulins level of fish fed diets containing antibiotics did not show any significant difference compared to the control group. The highest expression level of TNF-α, IL1β and lysozyme was observed in fish treated with 10 mg/kg FF while the lowest expression was noticed in those fish treated with 30 and 50 mg/kg FF. The present results indicate the relatively positive effects of this antibiotic on the immune system of zebrafish, and it seems that the appropriate dosage of the drug can serve as an immunostimulant for zebrafish.","PeriodicalId":36975,"journal":{"name":"International Journal of Aquatic Biology","volume":"44 1","pages":"211-217"},"PeriodicalIF":0.0,"publicationDate":"2019-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87719776","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 present study was aimed to study the metabolic bases of the temperature-dependent pathogenicity of the L. garvieae using 1 H NMR spectroscopy. The bacteria were grown at different temperatures, including 10, 14, 18 and 22˚C and then the metabolites extracted, identified and quantified. The results of PLS-DA analysis clearly separated the experimental treatments. The main metabolites responsible for this separation were acetate, acetoacetate, creatine phosphate, succinylacetone and trehalose. Furthermore, the result of the analysis of variance indicated also significant differences in metabolome content between temperature treatments. The bacteria exposed to higher temperatures showed more concentration of acetate and acetoacetate compared to those grown at 10°C. The concentrations of trehalose were higher in the bacteria grown at 14 and 18°C compared to other temperature treatments. The higher levels of succinylacetone were found in the bacteria exposed to the temperature less than 14°C compared to those grown at 18 and 22°C. The creatine phosphate concentrations increased with temperature, however, a significant decline occurred at 22°C. The levels of isoeugenol, methionine and betaine significantly declined with increase of temperature from 10 to 22°C. Also, the concentration of N-Acetylglutamine significantly raised as the temperature increased from 10 to 22°C. In conclusion, the temperature altered the metabolome of L. garvie , which this may be linked to the pathogenicity. The temperature probably affects fermentation, homeostasis, energetic condition and metabolism of amino acids in L. garvieae .","PeriodicalId":36975,"journal":{"name":"International Journal of Aquatic Biology","volume":"15 1","pages":"224-232"},"PeriodicalIF":0.0,"publicationDate":"2019-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81777643","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 Syrian coast is chracterized by many different types of habitats, including marine caves, midilittoral bioconstructions ( Lithophyllum byssoides rim and vermetid tarraces), coraligenous communities, sandy dunes, rocky coast and seagrass meadows. The present study summarizes early and most recent results on the presence, distribution, abundance and conservation status of marine alien species along the Syrian coast and provides an updated list of alien macrozoobenthic species. A total of 79 alien species belonging to Mollusca, Crustacea, Tunicata, Polychaeta, Spongia, Echinodermata and Chaetognatha are reported; among them Gastropoda is being the most abundant and successful taxon. In the light of these results, some recommendations on future research directions are provided. In particular, more effort is needed to monitor and record the entrance of alien species by adopting a comprehensive national plan to study marine biodiversity and to protect local resources in the Syrian marine environment.","PeriodicalId":36975,"journal":{"name":"International Journal of Aquatic Biology","volume":"5 1","pages":"180-194"},"PeriodicalIF":0.0,"publicationDate":"2019-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78345574","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}

Effective management and conservation plans require high accurate and reliable species distribution forecasts. Here, we modelled potential distribution of the genus Barbus in Iran, based on environmental variables using Species Distribution Models (SDMs). Six environmental predictors (i.e. slope, bankfull width, elevation, mean air temperature, range of air temperature and annual precipitation) were applied for modelling. The models were selected among different technique (GLM, GAM, CTA, SRE, GBM, RF, MARS, and FDA) which their results were summarized through ensemble forecasting approaches. According to the TSS (True Skill Statistic), the accuracy of the implemented models was greater than 0.8. The results showed that the projected distributions not only were observed in the same recorded basins but also in the new basins. Presented results deepen the conservation knowledge in Iran and act as a guidance for management decisions aimed at legal identification of critical habitats for species as well as informing them for translocation of threatened or captive-bred populations.","PeriodicalId":36975,"journal":{"name":"International Journal of Aquatic Biology","volume":"V 2 1","pages":"132-139"},"PeriodicalIF":0.0,"publicationDate":"2019-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73327133","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 purpose of this study was to identify a feeding regime for P. lividus that would allow adequate gonadal growth without accelerating the gamete maturation, in order to extend the market period. The purpose was pursued through the use of agar as a binding agent in the manufacturing of biocomposites to be used as feed for P. lividus and the realization of special offshore cages. The gonad index, histology, biochemical composition of fatty acids (FA) and free amino acids (FAA) and volatile molecule fingerprint were evaluated. Both the gonad index and the histological analysis showed a slower gametogenesis progression in the gonads of caged sea urchins with respect to the field collected ones, consistent with our previous results obtained testing a similar feed composition in a recirculating system. The amount and the relative proportions of FA and FAA in the gonads of wild and cultured gonads were similar, while the analysis of the volatile substances of the gonads of the sea urchin conducted using the electronic nose, shows that they vary as a result of the different feeding treatments. These results show that P. lividus sea urchins can be housed, under this feeding regime during the recovery phase of the gonads, without acceleration of the maturation of the gametes and thus in conditions to allow the extension of the market period. Moreover, the here tested agar-based biocomposites make it possible to reduce the management costs of the rearing system as they need to be replaced only once a week, and its environmental impact as they guarantee a limited nutrient dispersion in the water.","PeriodicalId":36975,"journal":{"name":"International Journal of Aquatic Biology","volume":"3 1","pages":"155-165"},"PeriodicalIF":0.0,"publicationDate":"2019-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80967206","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}
