水产养殖

针对养鱼业的可持续解决方案

水产养殖在世界粮食供应的管理和日益增长的鱼类需求方面发挥着关键作用。维兰德 BlueSea 产品有助于将养鱼组织成尽可能环保、可持续、低成本的业务。

当今水产养殖面临的最大挑战之一是环境保护。多数网箱都是采用尼龙等人造纤维制成。这些材料不但几乎不能回收利用、会导致海洋塑料污染，而且非常容易产生生物淤积或形成表面硬壳。因此，网箱需要复杂而昂贵的维护。此外，这种容易产生生物淤积的情况给网箱中生活的鱼类带来了很大的生存压力。这反过来又会带来复杂的处理要求，给鱼类造成更大的压力并阻碍它们的生长。

我们的解决方案

凭借丰富的设计、机械系统和材料搬运经验以及铜材专业知识，维兰德通过 BlueSea 产品可以提供一种环保型解决方案。

From the beginning in 2017 until completion in 2020, Wieland was part of the construction of one of the biggest offshore deepwater aquaculture farms in the world, built off the coast of China, in Mawei. Not only know-how about materials and installation but also 90t of Wieland BlueSea brass mesh were provided. Due to its high mechanical strength it not only resists predator attacks but also strong environmental loads and is therefore ideal for the Mawei offshore region, as it is a typhoon area.
