|EMW id||FAO species category||Scientific name||A multi-species category?||Lower estimated mean weight (EMW) (g)||Upper estimated mean weight (EMW) (g)||Smallest species in group EMW id||Largest species in group EMW id||Same species EMW id||Reliability ranking for Lower EMW||Reliability ranking for Upper EMW||Overall reliability ranking for this EMW||Max weight (g)|
The mean weight estimates for each species were obtained from a range of data sources (for details click on the link in the EMW id column), ranging from the lowest to the highest figure quoted at the highest level of reliability available. For multi-species categories, the range is the estimated mean weight of the smallest to the largest species believed to be farmed significantly.
