4. II. Seaweed Farming Defined: is the practice of cultivating and harvesting seaweed. In its simplest form , it consists of the management of naturally found batches. In its most advanced form , it consists of fully controlling the life cycle of the algae.

5. Did you know that… … Seaweed grows fast! T he weight of your seaweed can become 10 times heavier in 6 to 8 weeks. In other words, if you have a 150 gram plant to start, after 6 to 8 weeks that plant will weigh about 1.5 kilograms.

6. Did you know that … Thus, Eucheuma seaweed has a very fast growth; a clear advantage for the farmers!

7. VI. Methods of Culture : Net method It is the first commercially adapted technique in Eucheuma culture.  P lanting unit is a rectangular net measuring 2.5 × 5 m with a diagonal meshwork having a 25 cm bar length.

8. VI. Methods of Culture: Net is made up of monofilament nylon or standed polypropylene lines (110–150 lbs test) for the margin and 30–100 lbs test for the meshwork. Each net unit has 127 mesh intersections. Eucheuma seedlings are tied at these places using soft plastic straws (tie-tie).

10. VI. Methods of Culture: 1.2. Floating bamboo method a. Tie each corner of a 2.5 × 5 m net to a large coral with a cord so that the net is stretched tightly.

11. VI. Methods of Culture: b. Cut one meter piece of bamboo and tie one piece to each corner of the net. c. Add additional net to the previously constructed one.

12. Floating Bamboo Method “ Lantay ”

13. VI. Methods of Culture: 1.3. Mangrove stakes and nets a . Install mangrove stake bipod and tripod 6 meters apart in rows with 11 bipods or tripods in each row.

14. b. The rows should be 6 meters apart (11 rows can hold 20 nets). (BFAR Handouts). c. Attach 2.5 × 5 meters net to the bipods and tripods. Make sure all nets are stretched tightly and are at least 2 feet above the bottom but below the lowest tide level. VI. Methods of Culture:

15. Methods of Culture: 2. Bottom Monoline Method The fixed, off-bottom monoline method or bottom line method of cultivation is commonly used in commercial farms.

16. Methods of Culture: 3. Floating Monoline Method Opposite of bottom monoline method.

18. VII. Management of Farm 3. Harvesting of Seaweed Harvesting can also be made a part of the maintenance procedure. Eucheuma are harvestable when they reach the weight between 750–850 g.

19. VII. Management of Farm 3.1 Pre-harvest activities Prepare all the necessary harvesting materials such as baskets, sacks, knife and goggles. Prepare the drying area.

20. VII. Management of Farm 3.2 Harvesting Procedures a. Go row by row through the farm, harvest each plant by pruning. Remove branches from each plant using a sharp stainless knife. Leave about 200 g on each plant for regeneration .

21. VIII. Benefits of Seaweeds Blood Purifying: The chemical composition of seaweeds is so close to human blood plasma, that they are excellent at regulating and purifying our blood.  High in Calcium: They can contain up to 10 times more calcium than milk and 8 times as much as beef .

22. VIII. Benefits of Seaweeds Alkalizing: Helps our blood to neutralize the over-acidic effects of our modern diet. Have Powerful Chelating Properties: Offers protection from a wide array of environmental toxins, including heavy metals, pollutants&radiation by-products, by converting them to harmless salts that the body can eliminate easily .

23. VIII. Benefits of Seaweeds Contain Anti-oxidants: Seaweeds contain lignans (naturally occurring chemical compounds) which have anti cancer properties. Detoxifying: They are rich in chlorophyll which is a powerful, natural detoxifier that helps to draw out waste products .

27. IX. Uses of Seaweed Animal Feeds e.g seaweed meal ( Ascophyllum&Laminaria ) Fertilizers e.g. Liquid seaweed manure -promote resistance to plant disease& pests -induce fruit bearing -increase germination rates ALSO S eaweed is used to promote growth and soil condition, except for N,P,K, properties that already helps.

28. IX. Uses of Seaweed Commercial Use e.g.1 Body C ream The seaweed and seaweed extracts are good for the skin because it is beyond dispute according to cosmeticians and beauticians.

29. IX. Uses of Seaweeds Commercial Use e.g.2 Alginates I s widely used as a stabilizer or as an emulsifier, or both, and became very popular with the textile printing industry over the years. e.g.3 Agar ( gulaman ) I s use as a solid substrate for the growth of bacteria and fungi. Also, it could be utilize as food (dessert).

30. IX. Uses of Seaweeds Commercial Use e.g.4 Carrageenans Are ideal food additives: they have a range of gelling and emulsifying properties ranging from a soft slime to a brittle gel that one could nearly walk upon.
