Resumo: 	The worldwide distribution of the brine shrimp &lt;i&gt;Artemia&lt;/i&gt; , in a variety of isolated biotopes with different ecological conditions, has resulted in the evolution of many geographical strains. Among these strains, substantial differences have been demonstrated in their nutritional quality and fitness, providing a basis for the selection of strains suitable for aquaculture. The Tanggu Saltworks (Tianjin, China) provide a unique environment for the production of &lt;i&gt;Artemia&lt;/i&gt; . Unlike most other biotopes, they are characterized by a high primary productivity providing abundant food to sustain large populations of &lt;i&gt;Artemia&lt;/i&gt; . Both laboratory studies and field observations, however, indicate that the local parthenogenetic &lt;i&gt;Artemia&lt;/i&gt; strain has a low productivity (especially at lower temperatures) and a poorer resistance to high salinities than bisexual &lt;i&gt;A. franciscana&lt;/i&gt; strains. Moreover, the particular climatological conditions of the Tanggu region tend to retard the natural colonization of the saltworks in spring, which may result in suboptimal hydrobiological conditions for salt production. In this paper, we propose a biological management plan involving controlled introduction of a selected &lt;i&gt;Artemia&lt;/i&gt; strain with optimal productivity, and discuss possibilities to upgrade salt and &lt;i&gt;Artemia&lt;/i&gt; production qualitatively and quantitatively.
