In landlocked countries, the role of fish is often poorly known and/or propagated. In many countries fish represent the biggest and qualitatively most valuable protein source (24% of the worldwide available animal protein) for human consumption. At present the economic significance of the production and trade of fish is already very high. However, according to FAO, the future demand of proteins can only be covered by a considerable expansion of the aquaculture production, in particular because of a stagnated fish catch and a continuous reduction of the agricultural production. The ideational value of ornamental fish appears obvious however pet fish keeping represents also a value worth of many millions US dollars worldwide. Finally the importance of fish will not only increase for economic, but certainly also for ecological reasons, because it is well established as an incorruptible bioindicator of our environment.
在内陆国家，鱼类的作用往往鲜为人知且/或未得到广泛宣传。在许多国家，鱼类是供人类食用的最大且质量最有价值的蛋白质来源（占全球可获取动物蛋白的24%）。目前，鱼类生产和贸易的经济意义已经非常高。然而，据联合国粮食及农业组织（FAO）称，未来蛋白质需求只能通过大幅扩大水产养殖产量来满足，特别是由于鱼类捕捞停滞以及农业产量持续下降。观赏鱼的观念价值显而易见，然而全球范围内宠物鱼养殖也代表着价值达数百万美元的产业。最后，鱼类的重要性不仅会因经济原因而增加，当然也会因生态原因而增加，因为它已被公认为是我们环境的可靠生物指标。
