This page shows FAO reported fish aquaculture production tonnages (for the year and selected country above) by species category together with the estimated mean weight (EMW) (obtained in fishcount study) and estimated fish numbers. For species categories where no EMW was obtained, a generic mean weight was used to estimate numbers.
