The global seafood market is at a crossroads. While landings by global capture fisheries have leveled off, and many fish stocks have essentially collapsed, demand for seafood has been rising steadily, leading to the fast expansion of aquaculture. However, industrialized intensive finfish fed monoculture practices are showing they also have limits. Various approaches have been suggested to improve the deficiencies of the "Blue Revolution". One such responsible aquaculture practice, which we are developing in Canada, is integrated multi-trophic aquaculture (IMTA). The IMTA concept is based on an age-old, common sense, recycling and farming practice in which the by-products from one species become inputs for another: fed aquaculture (finfish) is combined with inorganic extractive (seaweed) and organic extractive (shellfish) aquaculture to create balanced systems for environmental sustainability (biomitigation), economic stability (product diversification and risk reduction) and social acceptability (better management practices).

全球海鲜市场正处于十字路口。虽然全球捕捞渔业的上岸量已经趋于平稳，许多鱼类种群基本上已经崩溃，但对海产品的需求一直在稳步上升，导致水产养殖的快速扩张。然而，工业化密集的鳍鱼喂养单一养殖的做法显示，他们也有局限性。人们提出了各种方法来改善“蓝色革命”的缺陷。我们正在加拿大发展的一种负责任的水产养殖做法是综合多营养水产养殖。IMTA的概念是基于一个古老的常识，回收和耕作实践，其中一个物种的副产品成为另一个物种的投入：饲料水产养殖（有鳍鱼类）与无机提取物（海藻）和有机提取物相结合，（贝类）水产养殖，为环境可持续性创造平衡的系统（生物融合）、经济稳定（产品多样化和减少风险）和社会可接受性（更好的管理做法）。
