Inland marine shrimp production is increasing in popularity as recirculating aquaculture systems (RAS) can provide a fresh, high-value product year-round to nearby consumer markets. However, artificial sea salt mixtures are required for inland production, which can be a substantial portion of the production costs. The purpose of this experiment was to compare marine shrimp (L. vannamei) production and water quality dynamics in culture systems with various mixtures of a least cost salt (LCS) formulation and a commercial, complete sea salt (CSS) formulation. Previous research using this same LCS mixture found decreased shrimp production using 100% LCS compared to ratios with 25% CSS inclusion and higher. To further investigate the decreased shrimp performance in 100% LCS, this experiment used six salt different ratios of LCS and CSS between 100% LCS and 75% LCS:25% CSS. The treatments used in this study were 100% LCS, 97.5% LCS, 95% LCS, 90% LCS, 80% LCS, and 75% LCS. The results showed that use of the LCS formulation significantly lowered the cost of salt kg^-1 shrimp produced. The LCS formulation cost $8.83 USD to make 1 m³ of water at 15 salinity, compared to $12.89 using the 75%/25% LCS/CSS mixture. Salt mixtures had a significant impact on DO, pH, salinity, and turbidity; however, these differences did not seem to impact shrimp performance, as no significant differences were found in shrimp average weight, biomass, survival, FCR, or growth rate. The results from this study indicate that using the LCS formulation reduces artificial sea salt cost significantly while having no significant impacts on shrimp production.

内陆海水虾生产越来越受欢迎，因为循环水产养殖系统 (RAS) 可以全年为附近的消费市场提供新鲜、高价值的产品。然而，内陆生产需要人工海盐混合物，这可能是生产成本的很大一部分。本实验的目的是比较南美白对虾（L. vannamei) 最低成本盐 (LCS) 配方和商业完整海盐 (CSS) 配方的各种混合物的养殖系统中的生产和水质动态。先前使用相同 LCS 混合物的研究发现，与使用 25% 或更高的 CSS 的比率相比，使用 100% LCS 的虾产量减少。为了进一步研究 100% LCS 对虾性能下降的影响，本实验在 100% LCS 和 75% LCS:25% CSS 之间使用了六种不同比例的 LCS 和 CSS。本研究中使用的处理是 100% LCS、97.5% LCS、95% LCS、90% LCS、80% LCS 和 75% LCS。结果表明，使用LCS配方显着降低了盐kg ^-1虾的生产成本。^{制造 1 m 3}的 LCS 配方成本为 8.83 美元盐度为 15 的水，而使用 75%/25% LCS/CSS 混合物的水为 12.89 美元。盐混合物对溶解氧、pH、盐度和浊度有显着影响；然而，这些差异似乎并未影响虾的生产性能，因为在虾的平均重量、生物量、存活率、FCR 或生长率方面没有发现显着差异。这项研究的结果表明，使用 LCS 配方可显着降低人工海盐成本，同时对虾生产没有显着影响。
