Seaweed growth rates

Since the early 1980s, yearly growth rates of around 10% have been reported for aquaeulture business. Because of this situation, global production of farmed fish and shellfish has more than doubled in both volume and value in the past 15 years (Naylor et al., 2000). If products from aquaculture that are not directly used for human consumption are included (e.g. seaweed), then the world s aquaculture production more than tripled by weight and value between 1984 and 1996 (Dagoon, 2000). The contribution of aquaculture to total fish production directly consumed by humans is currently more than 25%.
