In contrast, denitrification potential in wastewater and sediment was divergent, resulting in an uncertainty on net N₂O emission. We identified diverse ammonia-oxidizing bacteria assistors that were candidates for improving ammoxidation. Intriguingly, bacterial biomakers could quantitatively and accurately diagnose wastewater entropy water quality index and sediment multi-nutrient cycling index, with overall 81.9 % and 91.1 % accuracy, respectively.

Testing pooled samples, which involve collectively assessing multiple individual animal specimens, is the most efficient method in surveillance programs. Currently, despite its advantages, pooling for WSSV surveillance is not typically recommended due to its insufficient evaluation. Therefore, this study focused on assessing the applicability of pooling for WSSV surveillance. By evaluating the analytical performance, a reduction was observed, evidenced by the increased C_T values in the mixed group (pleopod + hepatopancreas) compared to those in the pleopod group. From the evaluation of the influence on diagnostic performance, pools showed a detection rate greater than 82.50 %, regardless of pool size, for G2–G3 severity grades. For the G0–G1 grades, the detection rate increased from 58.33 % to 93.33 % as the number of positive samples increased from 1 to 3 in a pool size of 5, whereas for a pool size of 10, the rate increased from 31.67 % to 86.67 % as the number of positive samples increased from 1 to 5. Notably, the cutoff values for the applicability of pools were determined to be 10^3.39 and 10^4.61 copies/mg for a single positive sample with pool sizes of 5 and 10, respectively. Similarly, in a simulation with 2 % prevalence and 160 shrimp, the detection rate for a pool size of 5 increased from 42.85 % to 80.86 % as severity grades progressed from G0–G1 to G1–G2, whereas for a pool size of 10, the detection rate improved from 46.73 % to 80.40 % as severity grades advanced from G1–G2 to G2–G3. Furthermore, at G0–G1, although a pool size of 5 showed 71.39 % surveillance sensitivity with a sample size of 150, it increased to 95.20 % with 360 shrimp. To adequately apply the diagnostic method for WSSV surveillance, it is necessary to consider the seasonal outbreak characteristics of the disease and pathogen activation. Based on these results, to enhance the efficiency and sensitivity of surveillance during the low-risk seasons for white spot disease (WSD), employing a pool size of 5 along with a larger sample size is recommended. Moreover, pooling could aid in rapid screening for WSSV during the endemic period. This study anticipates that pooling strategies tailored to the disease status may significantly contribute to reducing the incidence and spread of WSD through efficient and rapid testing.</div></div>","PeriodicalId":8375,"journal":{"name":"Aquaculture","volume":"597 ","pages":"Article 741938"},"PeriodicalIF":3.9,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142744628","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}

A triple-layered safety approach—bacterial attenuation, a suicide mechanism, and heat-killing—was implemented to minimize environmental risks. HKALM effectively delivered plasmids into shrimp hemocytes and intestinal cells, with the green fluorescent protein used as a reporter to enable detectable gene expression. Additionally, expressing the WSSV envelope protein VP53A through HKALM significantly increased phenoloxidase activity and improved shrimp survival rates after WSSV infection.

Hence, fattening experiment were conducted with immature male crabs with initial body weight of 153.65 ± 12.23 g, and the effects of formulated feed on fattening were analyzed with metabolomic and lipidomic approach. The results suggested no statistical difference in the growth and development of male crabs fattened with the feeds. The diet potentiated the immune response and repressed apoptosis in the gonads during fattening. Cholesterol accumulation and augmented fatty acid catabolism in the gonads were observed in the Feed group. Additionally, feed fattening diminished protein deposition. Metabolomic analysis indicated that feed fattening promoted lysine degradation and purine metabolism in the gonads. A further lipidomic study discovered that feed fattening mostly contributed to the boosting of phosphatidylcholines (PCs) that contain unsaturated fatty acids via the glycerophospholipid pathway compared to the trash fish group. Correlation analysis showed that enhancing gonadal lysine, purine metabolism and PCs could improve immune response and lipid metabolism. In summarize, the formulated diets effectively substituted trash fish for fattening and were superior in immunological promotion and lipid accumulation.

Aquatic species rely primarily on external sources (diet and the environment) for trace mineral nutrition. Trace element bioavailability differs among species and is influenced by the forms of minerals (organic or inorganic) and environmental factors. Rotifers that belong to the <em>Brachionus</em> genus play a significant role in aquaculture operations (by serving as live feed source for marine larval rearing) and are also important in ecological studies with regard to aquatic ecosystems. Rotifers engage in cyclical parthenogenesis, enabling rapid population expansion through asexual reproduction and the formation of resting eggs via sexual reproduction. The generation of resting egg facilitates long-term preservation and enables a consistent supply of rotifers. Rotifers are often subjected to trace element conditions through indirect trophic transfer or direct exposure in rearing systems or fields. The nutritional and toxicological effects of essential trace elements, such as iron, zinc, selenium, and copper in rotifers have been studied. While we identified species-specific modifications in reproductive patterns and metabolic activities, such as inhibited or enhanced sexual reproduction in different rotifers, with distinct responses in neutral lipid accumulation in reproductive organs and oxidative defenses within the <em>Brachionus plicatilis</em> species complex under iron and zinc exposure. Accordingly, we hypothesized that specific trace elements function as nutrients for growth and essential metabolisms, while also controlling the transition of rotifer reproductive patterns. To strengthen our understanding, this paper presented a systematic literature review on the effects of various essential trace elements, especially iron, zinc, selenium, and copper on the reproduction of rotifers. We elucidated the mechanisms from multiple perspectives, including behavior, biochemical, and genetic. This review also discussed aspects of their influence on phytoplankton–zooplankton–larval interactions, given the importance of trace elements in the aquatic food web. Finally, we outlined the regulatory effects of trace elements on intra- and interspecific responses from individual and population ecological viewpoints, and the ecophysiological significance of interactions with other elements and environmental factors. Understanding the interactions of rotifers with trace elements and the mechanisms underlying species-specific responses provides valuable insights into rotifer culture management and contributes to improved aquaculture practices.</div></div>","PeriodicalId":8375,"journal":{"name":"Aquaculture","volume":"597 ","pages":"Article 741933"},"PeriodicalIF":3.9,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142744448","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}
