Nile Tilapia was utilized in this study to assess the efficacy of incorporating garlic and cinnamon into their diet, aiming to enhance their immune systems and provide protection against <em>Saprolegnia</em>, a fungal pathogen that causes substantial economic losses in the fish farming industry. The findings indicated that the inclusion of garlic and cinnamon to the fish's diet enhanced their immune response and various blood parameters. Specifically, group 4, treated with 1.5% garlic, demonstrated superior outcomes compared to group 5, which received 2% garlic treatment. Additionally, group 6, subjected to 8.5% cinnamon treatment, exhibited superior hematological parameters when compared to group 7, which received 10% cinnamon treatment. Moreover, group 6 displayed the highest phagocytic activity in comparison to the remaining groups. In conclusion, garlic and cinnamon can serve as valuable immunostimulants for managing fungal infections in fish. Their inclusion in the diet enhances the immune response, consequently bolstering the fish's resistance to fungal infections.</div></div>","PeriodicalId":36894,"journal":{"name":"Aquaculture and Fisheries","volume":"10 1","pages":"Pages 105-114"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76172989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, some light characteristics necessary for maximizing efficiency have yet to be researched. The purpose of this study was to determine if there is a change in catch per unit effort (CPUE; number of snow crab per pot) and size selectivity of snow crab with varying light intensity. Three types of experimental luminescent-netting pots were used, each type with a different level of light intensity via the amount of phosphorescent strands woven into the pot netting, (either 2-, 4-, or 6-strands) and were compared to the traditional pot used in the fishery. There were mixed results among treatments, with the 2-strand pot catching fewer snow crab &lt;103 mm carapace width (CW) and more snow crab ≥103 mm CW than the traditional pots, but overall, had a lower CPUE for legal and sub-legal sized males (14.8 and 3.1 per pot, respectively) than the traditional (16.1 and 5.5 per pot, respectively) when considering all size classes. When compared to the traditional, the 4-strand pot caught more legal and sub-legal (CPUE of 18.8 and 8.0 per pot, respectively) snow crab in terms of CPUE but caught fewer commercial snow crabs from 95 to 98 and 103–113 mm CW. The brightest intensity pots (6-strand) showed no significant difference in CPUE or size selectivity in comparison to the traditional. Increased light intensity pots either had no effect on snow crab capture (6-strand) or produced unwanted results (loss of commercial sizes, increase in sub-legal sizes). Conversely, the 2-strand pot showed decreases in juvenile crab catch and increases in the catch of the most valuable size-classes observed, which are attractive results to fisheries managers and harvesters, respectively. These results, combined with a large price increase, suggest that higher light-intensity pots are not attractive for the commercial fishery.</div></div>","PeriodicalId":36894,"journal":{"name":"Aquaculture and Fisheries","volume":"10 1","pages":"Pages 124-131"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79181900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These stockings, however, increase the risk of accidental introductions and have led to introductions and subsequent invasions of gibel carp <em>Carassius gibelio</em>, a globally invasive and highly detrimental fish species. Here, we assessed the growth types, body conditions and trophic interactions via bulk carbon and nitrogen stable isotope analysis of common and gibel carp in both natural and artificial water bodies in Turkey. The results indicated that common and gibel carp express similar growth types and body conditions in all waters and have similar trophic ecologies. This leads to substantial trophic niche overlaps in waters where they co-occur, with the potential for strong interspecific competition. Considering the ongoing stocking of common carp for fishery enhancement, we recommend to specifically target these stockings in waters where gibel carp has already become invasive. Our findings, indeed, suggest that common carp releases have the potential to hamper invasive gibel carp populations by increasing the competitive interactions between the two species.</div></div>","PeriodicalId":36894,"journal":{"name":"Aquaculture and Fisheries","volume":"10 1","pages":"Pages 141-148"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91322003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
