复合养殖 - 现在是时候!我们是否准备好随时应对?

格雷姆斯2020耕海专题上讨论了最有前途的水产养殖技术--复合养殖,水培植物生产与循环养鱼的集成系统。肯塔基州立大学的查理·舒尔茨和大家讨论了复合养殖及其未来技术。

在过去的十年多年,复合养殖一直关注在维持生存水平系统。在美国,估计有1000 – 1500多个后院式养殖系统,还有约1000所学校基础的系统。根据与之相关的大学研究项目、短期课程、发表刊物的数量,这个数据还在不断增加。

复合养殖通过共享运营及基建成本、鱼排泄物与水的循环利用,提供了利润增长的巨大潜力。鱼的废弃物为植物提供了所需的营养物质,反过来水被植物过滤。已培育的复合养殖的热门配种包括罗非鱼,锦鲤,和尖吻鲈。

随着对有限养分和水供应全球需求的不断上升,复合养殖提供了可持续发展高效解决方案(热带或环境控制的温带地区达到200,000磅/英亩年产量)。 复合养殖在城市地区的大面积应用,可以减少对耕地的压力,同时延长水的使用,减少向环境的排放。

然而,我们仍然有许多工作要做...目前没有大规模的复合养殖商业模式存在,并且商业化的启动需要大量的密集资本。复合养殖企业必须在市场上获得两个截然不同产品的成功。有关食品安全的问题还有待研究和解决。不幸的是,合格的专家和专业人员供不应求。让我们向这一改变游戏规则的机会投入能量!现在是时候了!

Last year Aidan Connolly asked colleagues in Alltech's offices worldwide to help create a report on the global tonnage of animal feed produced. With offices and distributors in 128 countries he was able to put together a very comprehensive summary. That's not to say that it was easy. Data was collected from thousands of feed mills and manufacturers and compiled into totals for species, countries and regions.

Animal Agriculture Allies at IPE

Animal Agriculture Allies at IPE Kay Johnson Smith President Animal Ag Alliance

Livestock producers are under attack. Activist groups like the Humane Society of the United States and PETA are actively working to erode public opinion of animal agriculture and meat, milk and egg consumption. Furthermore, they lobby for additional regulations that will drive up food prices. Similar efforts in Europe have resulted in higher food prices. However, consumer preferences have not changed. The end result is increased importation and a loss of food security.
