With the global population projected to reach 10 billion by 2050, and global demand for protein projected to rise, aquaculture holds the key to a sustainable way to feed the world. U.S. demand for seafood exceeds domestic supply, so it imports seafood (50% from aquaculture), resulting in a trade deficit. The U.S. can help to ensure global food security, respond to the economic challenges of the Covid-19 pandemic, and shortage of food supply in the world by strategic expansion of aquaculture. For this to happen, it will require the development and demonstration of sustainable aquaculture technologies and practices. Sustainable finfish mariculture will mitigate depletion of wild fish populations, create jobs in rural and economically depressed coastal communities, increase regional food supply and nutrition security, reduce seafood trade deficit, and provide safe and nutritious seafood to the U.S.Currently, rapid aquaculture development is heavily dependent on conventional protein sources such as fishmeal and land-based agriculture products (commodity grains) are commonly used in aquaculture feeds, comprising up to half of the diets. However, fishmeal being a finite resource is expensive while commodity grains will have a supply threat in future being the main source of human and livestock food. As the mariculture industry in U.S. continues to expand, this work will test the most promising, eco-friendly and cost-effective diets that combine optimized levels of different non-conventional alternative protein sources, to establish market-driven regional feed suppliers, to apply these novel diets on commercial farms, and to evaluate the effects of these feeds on product quality.The spawning and culture techniques of the commercially important, high value marine finfish black sea bass Centropristis striata are already developed by the researchers at University of North Carolina Wilmington (UNCW). In phase 1, to develop the concept for the phase 2 work, the nutritional value of two non-conventional protein sources, single cell protein and Salicornia, (a salt tolerant halophyte) will be evaluated for black sea bass juvenile diets in controlled laboratory scale feeding trial in recirculating aquaculture system at the UNCW-Aquaculture Facility. A second trial will be conducted to find the best diets in combination with the findings of trial 1 and all alternative protein studies previously done at UNCW. Fishmeal and soybean meal will be replaced gradually by a combination of glandless cottonseed meal, poultry by-product meal, single cell protein, and Salicornia meal and other essential nutrients. The evaluation of growth, feed efficiency, and fish body composition will be analyzed. Data from phase 1 will be used to select the best diets to be tested at a commercial scale in phase 2. Cost-benefit, feed utilization, fish growth performance and fish fillet biochemical quality (e.g., omega 3 fatty acids) will be monitored.This proposal consists of interdisciplinary team members. Project results will establish key input components needed by commercial farmers - i.e., sustainable diets, domestic non-conventional ingredients, feed suppliers, and improved market value related to product derivation and taste. This research-based information will help to improve public perception of aquaculture as a clean industry in U.S. While this project focuses on black sea bass, the results will serve as a model for sustainable feed development to support the expansion of marine finfish production throughout the U.S.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

到 2050 年，全球人口预计将达到 100 亿，全球对蛋白质的需求预计将上升，水产养殖是以可持续方式养活世界的关键。美国对海鲜的需求超过了国内供应，因此进口海鲜（50%来自水产养殖），导致贸易逆差。美国可以通过战略性扩张水产养殖来帮助确保全球粮食安全、应对Covid-19大流行的经济挑战以及世界粮食供应短缺。为此，需要开发和示范可持续水产养殖技术和实践。可持续的有鳍鱼类海水养殖将缓解野生鱼类种群的枯竭，为农村和经济萧条的沿海社区创造就业机会，增加区域粮食供应和营养安全，减少海鲜贸易逆差，并为美国提供安全和营养的海鲜。依赖传统蛋白质来源，如鱼粉和陆基农产品（商品谷物）通常用于水产养殖饲料，占日粮的一半。然而，鱼粉资源有限，价格昂贵，而商品粮作为人畜食品的主要来源，未来将面临供应威胁。随着美国海水养殖业的不断扩张，这项工作将测试最有前途、环保且具有成本效益的饲料，这些饲料结合了不同非传统替代蛋白质来源的优化水平，以建立市场驱动的区域饲料供应商，以应用在商业农场中使用这些新颖的饲料，并评估这些饲料对产品质量的影响。大学的研究人员已经开发了商业上重要的高价值海洋鱼类黑鲈Centropristis striata的产卵和养殖技术北卡罗来纳州威尔明顿 (UNCW)。在第一阶段，为了开发第二阶段工作的概念，将在受控实验室规模下评估两种非常规蛋白质来源（单细胞蛋白质和海蓬子（一种耐盐盐生植物））对黑鲈幼鱼饮食的营养价值UNCW 水产养殖设施循环水产养殖系统的饲养试验。将进行第二次试验，以结合试验 1 的结果以及之前在 UNCW 进行的所有替代蛋白质研究来找到最佳饮食。鱼粉和豆粕将逐渐被无腺棉籽粉、禽副产品粉、单细胞蛋白、海蓬子粉等必需营养素的组合所取代。将分析生长、饲料效率和鱼体成分的评估。第一阶段的数据将用于选择最佳日粮，以便在第二阶段进行商业规模测试。将监测成本效益、饲料利用率、鱼生长性能和鱼片生化质量（例如欧米伽 3 脂肪酸）。该提案由跨学科团队成员组成。项目结果将确定商业农民所需的关键投入要素，即可持续饮食、国内非传统原料、饲料供应商以及与产品来源和口味相关的提高的市场价值。 这些基于研究的信息将有助于提高公众对美国水产养殖作为清洁产业的认识。虽然该项目的重点是黑鲈，但其结果将作为可持续饲料开发的模型，以支持扩大美国各地的海水鱼类生产。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
