than half of seaplants come from sustainable aquaculture - an
opportunity for thousands of coastal people.
market for seaplants is very conservatively estimated at over
two million tons of seaplants valued at seven billion US
dollars per annum. Since many seaplants and their products
are exchanged in local markets there are no statistics kept and
actual market volumes are probably many time this.
products include human food, animal feed, plant food, food
supplements, food ingredients, personal care preparations,
wellbeing products, medicines and process aids.
has more than 200 useful seaplant species distributed among more
than 150 bodies of water. Thirty countries/territories
possess over 80% of the world's seacoast... most are significant
seaplant producers. Currently there are 214 countries or
territories in the world that have seacoast (click
to list). Of these 42 have reports of
commercial seaplant activity and these are included so far in
the SuriaLink GIS. The top ten
countries/territories in terms of coastline length have 63%
of the world's total of 531,864 km.

producing countries contribute 96% of the world's commercial
seaweed volume of over two million tons. About 50% of world
production is cultivated. The seven top seaweed farming
countries produce 99% of the volume. East Asia and Western
|About 70% of
world seaweed production is accounted for by
Lithothamnion spp. + Phymatolithon
spp. (a.k.a. maërl; as wet weight ) and Laminaria
spp. (a.k.a. kelp, kombu or hai dai; as dry weight). The
"top ten" genera comprise more than 95% of world
production. About half of the over 2 M tons/yr produced
is from cultivation. Laminaria
spp. accounts for over 60% of the total while Porphyra,
make up most of the rest to a total of 99%.
