The 2018 Census of Aquaculture, released last month by the US Department of Agriculture's National Agricultural Statistics Service (NASS), shows sales of aquaculture products in 2018 reached $1.5 billion (€1.4 billion) an increase of 10.5 percent from 2013.

Aquaculture products sales--which includes food fish, sport fish, bait fish and ornamental fish -- were dominated by catfish and oysters, according to the study.

Catfish sales, valued at $366.8 million (€329.2 million), accounted for 51 percent of all food fish sales in 2018.
