Coastal solar saltworks of Brazil are exploited for sea salt, which becomes progressively concentrated by evaporation. This study aimed to review the current and new potential uses of these systems, in order to provide more dynamic for this activity. The first evaporation ponds are also used for artisanal fisheries, ensuring the livelihood of many families. All the brine rich in secondary salts (bittern) can be widely used by the chemical industry, while the Brazil shows an incipient production of "flower of salt", a salt with distinct characteristics with higher market value than sodium chloride. On the other hand, the saltponds have a high potential for management and obtaining of large populations of Artemia spp., purifying the brine through the action as biological filter. This microcrustacean occurs naturally in intermediate salinity ponds, being commonly used in aquaculture. Species of microalgae and halobacteria found in the saltworks are employed for extraction of beta-carotene and glycerol, used in an extensive list of products with high commercial value. These ecosystems represent refuge zones for many species of migratory birds, becoming imperative to promote the conservation of these hypersaline wetlands.
巴西沿海的太阳能盐场用于生产海盐，海盐通过蒸发逐渐浓缩。本研究旨在回顾这些系统当前和新的潜在用途，以便为这项活动提供更多动力。首个蒸发池还用于个体渔业，保障了许多家庭的生计。所有富含次生盐（卤水）的盐水可被化学工业广泛利用，而巴西的“盐花”生产刚刚起步，“盐花”是一种具有独特特性且市场价值高于氯化钠的盐。另一方面，盐池在管理和获取大量卤虫属方面具有很高潜力，卤虫属作为生物过滤器可净化卤水。这种小型甲壳动物自然存在于中等盐度的池塘中，常用于水产养殖。盐场中发现的微藻和嗜盐细菌物种可用于提取β-胡萝卜素和甘油，它们被广泛用于众多具有高商业价值的产品中。这些生态系统是许多候鸟的避难区，因此促进保护这些高盐湿地变得势在必行。
