ecosystem services
Regulating
Benefits obtained from regulation of ecosystem process
Such as climate control and disease control with technology
supporting

Such as production of food and water
habitat
Importance of ecosystems as habitats
for migratory and local species
Aquaculture
Artificial areas where aquatic lives are cultivated for human use
Farming of aquatic organisms such as fish, crustaceans and aquatic plants
Provide food, income & employment
Contribute to rehabilitation of coastal rural areas
Chanthaburi province, Eastern Thailand
Water SA of bay is 15,000,000 m2
Water depth is usually 70-300 m
Highly suitable for aquaculture activities
Activities in Kung Krabaen Bay
Reallocation of Mangrove area and Paddy field for Aquaculture
Shrimp Culture Project with Environmental Conservation
Crab Sustainability Project
Oyster culture
Shrimp Culture Extension with Environmental Conservation
Initiated to protect fertile mangrove forest from human destruction
Economic boom in the industry
Cause environmental degradation
Land originally owned by small-scale rice farmers and small-scale fisheries
Initiated to protect the crabs prone to pollution caused by human activities in mangroves
Efforts are not very sustainable as most cultivated crabs are saltwater crabs, whose larvae are planktonic (very small and difficult to cultivate)
"Baby crabs” taken from the wild and sold --> affect marine ecosystem

oYSTER CULTURE
Oyster seed beds introduced by Department of Fisheries aiming to increase oyster seeds to 1. Support oyster culture 2. Control amount of plankton 3. Improve quality of water
Oyster culture done by hanging method.
Reaps high yields and also makes it easy to take care and harvest the oysters
High capital inputs
Can also lead to environmental problems mainly water pollution

coastal features
Rhizophora tree saplings planted in straight rows
Spit
Shallow waters
crab sustainability project
