The production and use of Eucheuma

Only gelatinae tolerates direct wave action. Sea temperatures are usually correlated with but lag behind sunlight intensity in an annual cycle. For these reasons, as in terrestrial agronomy, farming is done only on fiat places. For Eucheuma, deep water habitats are of no commercial importance.

However, the largest volume of alkali-treated Eucheuma is in pet foods where it is used as a powdered, granulated or hydrated gel component in the various formulations. Their molecular weights may be as high asMaking alkali-treated Eucheuma seems to consume most of the cottonii Eucheuma produced, for it is far less expensive than extracted carrageenan. Algaebase is sponsored by: Information based on morphological characteristicsDNA fingerprintingand growth performance during different crop seasons is used to facilitate Eucheuma crop management, for which high-growth species are used for seed stocks, mostly from the Philippines.

Academic Press, p. Productivity data in terms such as world crop, number of families concerned or dollar values are very scarce or nonexistent, and those discussed below are much of what is available.

While harvesters usually carry a large knife; this and even hats and shoes are not requisite to wild crop harvesting. Retrieved 19 December There are no effective formal mechanisms for consultation between the levels of concern in the Eucheuma industry.

Seasonal growth and reproduction. See below under micro-grazers. Thus the size at which harvesting would best take place, the euchruma size, is different in different places, though the strain and agronomic treatments may otherwise be the same. Since the mids, Kappaphycus and Eucheuma have been a major source for the expansion of the carrageenan industry. Eucheuma striatum Tambalang and Elkhorn varieties and E.

There are two types in this category. For this purpose the seaweed is usually scattered on rock or bamboo surfaces as this obviates sand, soil and trash being added.

Temperature and light are felt to be relatively independent of water motion and its quality. Eucjeuma with ‘species’ microformats All articles with unsourced euchehma Articles with unsourced statements from June Commons category link is on Wikidata. Only upstream values are given in the seasonal part of the table. Repeating structures of galactan sulphates from Furcellaria fastigiata, Gigartina canaliculata, G.

Their locally made family boat is often used. Some effort has been put forth to obtain use of the filter aid waste from the carrageenan extraction plants as a soil conditioner.

On reef flats there is no conflict with fisheries useage or with ocean navigation. However, the larger the thalli become, the more susceptible they are to physical damage and loss.

Only in those countries where there was no contrary legislation and the ultimate processing companies from abroad have sent in expatriate management has introduction led to farming and regular export.

The onset is a sharply limited greening of a segment which, the next day, is clearly green and in one or very few more days very pale, then white.


Eucheuma isiforme

No attempt is being made here to describe farm siting, construction and operation beyond what is to be found in other sections of this case study. Tham Ah Kow were working cooperatively at the time and only with cottonii. Most if not all evaporated milk nowadays contains carrageenan as the component that makes possible its pleasant flavor and thick, creamy quality. Macroalgas marinas de Cuba. The carrageenan extraction process itself is well known to be a hot water, high pH, process. Lyon Arboretum Lecture Number Eleven.

Site selection is important in developing potential seaweed farms, and certain criteria must be met first in order to optimize production. The Hawaiian study reveals some of the environmental parameters Table 3 within which Eucheuma thrives; it also indicates that spinosum and the two principle strains of cottonii grow Table 6 at different rates and may have different seasonalities. The village leader accumulates the seaweed and sells or barters it to the entrepreneur or trader, who will probably be but a representative of a traditional exporter.

In yet other places they are avidly sought out and eaten. Thus, Eucheuma farming is a ready way of improving family income. List of seaweed traders worldwide. Seaweed quality Dry wt. Domestic pollution from farmhouse waste disposal may also impact the nearby environment. Kraft does describe E. Eucheuma gelatinae showing the flat branches arising from marginal cylindrical teeth.
