Marine biota is a great source of ecosystem services. Recently, the involvement of marine organisms in biotechnological applications has been discovered and become useful for the development of alternative and healthy food, natural medicine and cosmetics. The most known ecosystem service is the provision of seafood; however, fishery management has to be implemented in order to avoid fishing exploitation, depletion of the sea and assure the recruitment by fish larva. This review put in relation the role of zooplankton in the ecosystem and its importance in fish recruitment. Zooplankton and fish are close connected; indeed, their prey-predator relation is an important factor for fish recruitment. Understanding the dynamic and trophic relation among different groups (phytoplankton – zooplankton – fish) and the ecosystem services they give to us, may increase the awareness of the importance to preserve marine environments. Furthermore, this relation is also important for fish aquaculture practices, as it is discussed in the present review. Further researches on potential zooplankton species that may be involved in fish farms may also ameliorate aquaculture services.

To preserve the seas from fish depletion and to assure seafood provision, it is fundamental to have deep knowledge about the ecological connections in the marine environment and to obtain fishery management respectful for the environment.

海洋生物群是生态系统服务的重要来源。最近，已发现海洋生物参与生物技术应用，并有助于开发替代和健康食品、天然药物和化妆品。最著名的生态系统服务是提供海鲜；然而，必须实施渔业管理，以避免捕捞开发、海洋枯竭和确保鱼幼虫的补充。本综述将浮游动物在生态系统中的作用及其在鱼类补充中的重要性联系起来。浮游动物与鱼类关系密切；事实上，它们的猎物-捕食者关系是鱼类补充的一个重要因素。了解不同群体（浮游植物 - 浮游动物 - 鱼类）之间的动态和营养关系以及它们为我们提供的生态系统服务，可能会提高对保护海洋环境重要性的认识。此外，正如本综述所讨论的，这种关系对于鱼类水产养殖实践也很重要。进一步研究可能涉及养鱼场的潜在浮游动物物种也可能改善水产养殖服务。

为了保护海洋免于鱼类枯竭并确保海产品供应，深入了解海洋环境中的生态联系并获得尊重环境的渔业管理至关重要。
