Many countries today produce and consume laminaria products; the largest producer is China. Laminaria japonica, the important commercial seaweed, was first introduced into China in the late 1920s from Hokkaido, Japan.

Saccharina latissima is a yellowish brown colour with a long narrow, undivided blade that can grow to 5 metres (16 ft) long and 20 centimetres (8 in) wide. The central band is dimpled while the margins are smoother with a wavy edge, this is to cause greater water movement around the blades to aid in gas exchange.
Fucoidan is a long chain sulfated polysaccharide found in various species of brown algae.Commercially available fucoidan is commonly extracted from the seaweed species Fucus vesiculosus (), Cladosiphon okamuranus, Laminaria japonica (kombu, sugar kelp) and Undaria pinnatifida ().
An American kelp farmer, Bren Smith of GreenWave explains his farming methods, including the symbiotic relationship kelp has with other seafood he grows..
