Featured species group: crayfishes

The 1 711 635 tonnes of world aquaculture production of crayfishes – a subgroup of the ISSCAAP 

group “freshwater crustaceans”, including freshwater decapod crustaceans of the superfamilies 

Astacoidea and Parastacoidea – made it the #13 largest species group in world aquaculture 2018; 

see the chart on the back cover. 

While the 43 percent production growth between 2017 and 2018 (the highest among the top 

50 species groups) has helped it move up one place from #14 to #13 (overtaking marine perch-like 

fishes), crayfishes has yet to become one of the top 10 species groups by tonnage. However, 

crayfishes was the #4 species group by value accounting for 5.49 percent of the world aquaculture 

farmgate value in 2018, following salmons, trouts, smelts (8.65 percent), marine shrimps and prawns 

(14.6 percent) and carps, barbels and other cyprinids (23.67 percent) – more details can be found 

in the Supplementary Materials. 

The Food and Agriculture Organization of the United Nations (FAO) statistics record 12 countries 

cultivating crayfishes in 2018 (Table 2), yet the production was dominated by only two countries: 

China (95.74 percent) and United States of America (4.25 percent). 

The FAO statistics record seven crayfishes species items being farmed worldwide in 2018, yet red 

swamp crawfish (Procambarus clarkii) accounted for nearly the entire production tonnage; and most 

of the 12 crayfish farming countries focused on only one species item, with Australia being the only 

exception (Table 2)
