1 Blue Revolution

2 Message In 2013, we defined Leading the Blue Revolution as our vision. To us, Leading the Blue Revolution is both an ambition and a promise. We aim to be a leader in cultivating and growing food from the ocean. We want to play our part in solving one of the greatest challenges of our time – producing enough healthy and sustainable food for a growing world population. More than 70% of the globe is covered by water, yet only 2% of the worlds food supply comes from the ocean. We have to produce protein in a more energy efficient and environmentally responsible manner. Aquaculture has the potential to achieve this. That is why we say blue is the new green. (Alf-Helge Aarskog)

3 Introduction since 1950, there has been a 100 percent increase in demand of fish world consumption of aquatic proteins is predicted to rise to 155 million tons however, traditional fisheries can only provide up to 100 million tons actions must be done to meet up with the demand

4 Definition the water equivalent of the green revolution movement aimed at increasing drastically the global food production using aquaculture Aquaculture: refers to all forms of active culturing of aquatic animals and plants, occurring in marine, brackish or freshwaters.

5 Introduction an attempt to protect marine life and to ensure sufficient seafood for the present and future generation encourage fish farming significant increase in the amount of fish available prices of fish have fallen

6 usage of fish hatcheries to supply farms and enhance livestock – a more traditional method the world has now advance into the second stage of the revolution –genetic engineering –Splicing genes from one fish species to another

7 fish farming (hatchery)

8 Genetically engineered fish

9 medicine and vaccines are used to improve the health and nutrition of the fish developed ways to increase/improve: –Fertility of fish –Growth rate –Resistance to diseases

10 Case study - Singapore Singapore has developed its very own super sea bass hatched in the research tanks of the Agri-Food and Veterinary Authority's (AVA) Marine Aquaculture Centre (MAC) on St John's Island Improved sea bass are / have: –a survival rate of up to 80 per cent –twice as hardy –able to grow up to 15 per cent faster, reaching market size (about 500g) in under six months Taken from the Straits Times, Oct 05, 2007

11 Fish Farming freshwater fish are most commonly cultivated in North America and Europe Most commonly cultivated fish: –Trout –Catfish –Carp

12 fish grown under brackish-water conditions are much lesser located in Northern Europe, America and New Zealand commonly cultivated fish include: –Trout –Salmon

13 Fish Farming various species of fish are grown in agriculture, using a variety of cultivation systems –Confinement in artificial ponds –In cages set into larger bodies of water (e.g. sea) fish are fed with a nutritious diet to maximize growth rate carefully harvested and processed when fish become mature

14 fish farming in cages

15 Benefits anticipated that the world would not have to face shortage of fish supplies in the next 3 decades access to a large production of nutritious, high-quality foods Populations of fish can be very productive (fish are cold-blooded; they divert little energy to maintain their body temperature, hence a large proportion of their food can be converted into their growing biomass)

16 Concerns raised habitat destruction (e.g. mangroves) and water diversions that disrupt aquatic ecosystem waste water from the pond pollutes the sea salt water from the fish farms may seep into the ground, causing an increased salinity which damages water supply and surrounding agriculture land

17 algae on Carter's Beach originated from activities at the fish farm nearby

18 Close up view

19 many farmers have been displaced from their lands to make way for aquaculture flow of salt water to the rice-fields reduces farm output fishermens catch is greatly reduced rural households located near the fish farms face severe water problems

21 Case Study - Bangladesh thousands of farmers have suffered from the invasion of their farms by aquaculture owners destruction or damage to their rice crops by seepage of salt water from the shrimp ponds shrimp owners have been buying up the farms very cheaply, rendering them landless

22 estimation of 300,000 people being displaced from their farmlands by aquaculture in the Stakhira region alone disputes between farmers and aquaculture owners have led to violent clashes, with the death of at least two villagers to date.

23 Case Study - Malaysia several thousand fishermen suffered huge decline in catching fish due to: –Clearing of mangroves –River pollution caused by aquaculture ponds
