Everything about Mariculture totally explained
Mariculture is a specialized branch of
aquaculture involving the cultivation of marine organisms for
food and other products in the open
ocean, an enclosed section of the ocean, or in tanks,
ponds or
raceways which are filled with
seawater. An example of the latter is the farming of
marine fish, including
finfish and
shellfish for example
prawns, or
oysters and
seaweed in saltwater ponds. Non-food products produced by mariculture include:
fish meal,
nutrient agar,
jewelries (for example
cultured pearls), and
cosmetics.
Sea ranching
The Japanese have developed a process for free ranching marine fish or
sea ranching. The principle is based on
behavioral conditioning and the migratory nature of certain species of marine fish. The fishermen first raise fish hatchlings in a closely knitted net in a harbor. They sound an underwater horn before each feeding. When the young fish are old enough they're freed from the net to mature in the open sea. During spawning season, about 80% of these fish return to their birthplace. The fishermen harvest the fish by sounding the horn and then raising the net.
Kelp farming
Kelp can be farmed in at least two ways. They can be grown around a rope that's anchored to the sea floor the plants don't drift away.
Off the coast of
California, the top few feet of natural
kelp beds are harvested by boats with mowers. Kelp provides
alginin, an edible material used in
ice cream and
cosmetics. The industry also supplies the
dietry supplement industry
