The term shrimp, as used by the Food and Agriculture Organization (FAO), covers all shrimp (Caridea) and prawns (Dendrobranchiata, comprising Penaeoidea and Sergestoidea) – a group formerly known as “Natantia“.This nomenclature often differs from local use, in which the same species may be known by different names, or where different species may be known by the same name.

Midwater trawling is trawling, or net fishing, at a depth that is higher in the water column than the bottom of the ocean. It is contrasted with bottom trawling. Midwater trawling is also known as pelagic trawling and bottom trawling as benthic trawling.In midwater trawling, a cone-shaped net can be towed behind a single boat and spread by trawl doors, or it can be towed behind two boats (pair trawling) which act as the spreading device.
