This approach links a simplified model estimating the budget of suspended particulate organic carbon (POC) in a farm with dynamic energy budget models that calculate the growth of cultivated oysters (<em>Crassostrea gigas</em>) and fouling mussels (<em>Mytilus galloprovincialis</em>). By simulating the effect of mussel removal using hot-water treatment conducted in an oyster farm in northeastern Japan, we estimated that treatment at the 12th month after the start of cultivation would increase the soft body weight of oysters harvested at the 18th month by 11 % compared to the no-treatment case. Mussel removal was also predicted to reduce the bivalves' biodeposition to 19 %. Further estimations across assumed wide ranges of background POC concentrations (up to 1.5 mg-C L⁻¹) and fouling-mussel density on cultivated oysters (up to 100 individuals per oyster) indicated that mussel removal more effectively enhanced oyster growth (by over approximately 5 %) in intermediate POC concentrations (0.02 to 0.2 mg L⁻¹) and relatively higher mussel densities (&gt;10 individuals). The percentage of reduced biodeposition due to mussel removal was higher in relatively lower POC concentrations. The proposed models can predict the benefits of removing fouling mussels in oyster aquaculture—namely, increased oyster production and reduced environmental impact—considering site-specific conditions. These models can help determine the necessity of costly biofouling controls.</div></div>","PeriodicalId":8375,"journal":{"name":"Aquaculture","volume":"605 ","pages":"Article 742531"},"PeriodicalIF":3.9,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the Indo-Pacific region, several species stand out as promising low-trophic candidate species for modern hatchery-production programs, particularly those in the <em>Saccostrea</em> genus. However, no formal studies have compared the productivity of these species, despite the critical importance of this information for effective resource management and planning. Here we first studied the distribution of <em>S. cucullata</em> and <em>S. echinata</em> across four islands in the Society Archipelago of French Polynesia using phylogenetic analyses and multiplex PCR. Secondly, we described the hatchery protocols used for successfully conditioning oyster broodstock, inducing spawning and fertilisation. Lastly, we evaluated the growth performance of oysters at each stage in the hatchery-production process: larval development, nursery growth, and grow-out. Results showed that <em>S. echinata</em> consistently outperformed <em>S. cucullata</em>. Observations during the grow-out phase highlighted the importance of site selection for optimal growth—which correlated with water temperature, salinity, and food availability—while also revealing differences in survival that are potentially associated to the presence of nuisance species (e.g., flatworms, Stylochidae, and predatory snails, Cymatiidae) present in their natural environment. Finally, we found that <em>S. cucullata</em> invests more energy into reproduction than <em>S. echinata</em>, likely explaining the strong differences in growth performance. This study demonstrates the superior performance of <em>S. echinata</em> and its potential as a candidate species for hatchery-based oyster aquaculture in French Polynesia. We recommend that the holistic comparative approach we used here could be considered as a decision-making-tool in aquaculture management widely.</div></div>","PeriodicalId":8375,"journal":{"name":"Aquaculture","volume":"605 ","pages":"Article 742543"},"PeriodicalIF":3.9,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143799607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most studies have focused on optimizing dietary formulations to address this issue, overlooking the influence of the physical properties of the diet on <em>Eriocheir sinensis.</em> In this study, a novel sodium alginate–based hydrogel (SAH) diet was developed to investigate the effects of its soft particle texture on the growth and digestion of <em>E. sinensis</em>. Growth experiment: Crabs were fed three diets with different textures—FTF, pellet diet (PED), and SAH (SA12.5 %)—over an 8-week period. The initial average weight of each group was 75.3 ± 0.75 g. No significant differences in growth performance were observed among the three diet groups. The analysis of digestive enzyme activity in the hepatopancreas showed a notable increase in trypsin activity in the SAH group compared with the FTF group, while lipase, α-amylase, and cellulase activities showed no significant differences. The examination of digestion-related gene expression in the intestine revealed notable upregulation of <em>crtb1</em>, <em>il</em>, <em>espt</em>, <em>pm1</em>, and <em>pm2</em> genes in the SAH group. Additionally, gut microbiota diversity increased, whereas richness decreased in the SAH group. Apparent digestibility test: Five SAH diets with varying SA (SAH1 [SA8.33 %], SAH2 [SA9.09 %], SAH3 [SA10 %], SAH4 [SA11.01 %], and SAH5 [SA12.5 %]) were tested, with PED serving as the control (CON). The apparent digestibility of dry matter, crude protein, crude lipid, total phosphorus, and total amino acids in SAH3 and SAH5 groups was significantly higher than that in the CON. In conclusion, the SAH diet improved the digestive performance of <em>E. sinensis</em> without adversely affecting growth, leading to notable improvements in digestive enzyme activity and apparent digestibility.</div></div>","PeriodicalId":8375,"journal":{"name":"Aquaculture","volume":"605 ","pages":"Article 742516"},"PeriodicalIF":3.9,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fish exposed to CLEO concentrations reached a deep anesthesia stage in a concentration-dependent manner. However, the effects obtained during anesthetic induction were reversible, both in behavioral parameters and cardiac activity. The mechanism of action was observed after administration of flumazenil 1 mg/kg i.p., which showed greater resistance to loss of postural reflex and shorter latency for recovery. The mechanism of action indicates involvement of inhibitory GABA neurotransmission.

This article examines the positions of coastal municipalities on aquaculture expansions, being key actors in authorizing new areas for salmon farming. A reasonable assumption is that municipalities with significant environmental problems may be negative towards further growth. Yet, a long and varied scholarship on environmental politics shows that economic interests tend to trump concerns raised by environmental problems. We thus seek to investigate how environmental problems and dependency on aquaculture industry clusters affect Norwegian municipal positions on aquaculture expansion in their area planning. Selecting ten municipalities for in depth studies, we apply a qualitative comparative analysis approach to examine the proposition that municipalities hosting strong aquaculture industry clusters (AC) will be positive to expansion, regardless of the state of the environment. Our examinations largely support this proposition but also reveals nuances and deviant cases. We find that the effect of AC on positions is weaker in municipalities hosting large, externally based corporations than in those hosting smaller and locally entrenched companies. Furthermore, the effect of AC appears to be weak in larger and more economically diverse municipalities compared to smaller municipalities.</div></div>","PeriodicalId":8375,"journal":{"name":"Aquaculture","volume":"605 ","pages":"Article 742494"},"PeriodicalIF":3.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
