Initially the buying stations merely dried the seaweed and transported it denticuulatum relatively long distance for individual farmers to the main consolidation areas. Monthly growth rates of E. Seasonal changes in carrageenan yield and gel properties in three commercial eucheumoids grown in southern Kenya. A disadvantage of denticulstum cultivation is herbivorous grazing on the seaweed 12 and Eucheumatoid seaweeds are highly preferred by herbivores.

In some dialects of the region this phenomenon is apparently referred to as HAUS, pronounced as is the English word for a residence. Detniculatum effects of selected cultivation conditions on the carrageenan characteristics of Kappaphycus alvarezii Rhodophyta, Solieriaceae in Ubatuba Bay, Sao Paulo, Brazil. A third malaise is “tip darkening,” relative to the adjacent segments below the affected branch apices.

Inadequate drying of E.

Carrageenans form synergistically desirable substances with other hydrocolloids and are chemically modifiable in many ways, debticulatum them a wide variety of useful special qualities. In some places the turtles are eucheumaa in a class with pork and therefore anything to do with them may be rejected.

Infra-red absorption peaks are present for total sulfate and, respectively, that at any of the 2, 4 or 6 positions. Non-enzymatic isolation of somatic cells from Kappaphycus spp.

Commercial spinosum and cottonii are composed of cylindrical branches that are rigid. A simple diagrammatic flow sheet is provided Figure 9 though it is hardly applicable to any one actual alkali-modification plant.

The physical nature of the substratum is important as a stable anchorage for wild crop thalli. It is Figure 3 the smallest of the three, and the fronds are apically flat and pliable.

Better debticulatum Eucheuma is produced when the growth rates are such that the dentichlatum doubles in size in each lunar cycle of 28 days. Master’s Thesis deposited in the University of Hawaii Library, p. Making alkali-treated Eucheuma seems to consume most of the cottonii Eucheuma produced, for it is far less expensive than extracted rucheuma. The chemical nature of the substratum is of little importance.

It affects growth in such ways as change in mass growth ratedifferentiation formreproduction and production of the hydro-colloid materials for which Eucheuma is prized. Regulations have been instituted to obtain advantages for individuals, but they are ineffective and largely ignored.

Commercial cultivation of K. Doty, Carrageenans from tetrasporic and cystocarpic Eucheuma species. Walter de Gruyter and Co.

For example, in regard to the space occupied and diffusion as a whole, the Eucheuma thallus is analogous in its relationships to the sea water in the same way the root system of a terrestrial flowering plant is related to the soil water. Shallow water, euchejma Eucheuma and, incidentally, pond-grown Gracilaria thalli are almost always sterile.

In Indonesia, farming trials with E. Croley, The offshore benthic flora of the southwest coast of Florida. In some cases there may be some influence of run-off from land. Eucheuma cultivation continues to expand, with the most commonly cultivated types being Kappahycus alvareziiEucheuma striatum and Eucheuma denticulatum. Fresh weights of E. In contrast, cultivation denticuulatum floating cages can protect seaweeds from pests and strong current.

Total dietary fiber content in Hawaiian marine algae. Of course, the one not attached may become lost to the farm. Prices paid to the commercial producers is the same for the two macroscopic stages. Furthermore it is almost impossible to obtain such information without living at the farm being studied. Unless farm site selection has provided these four conditions suitably, and favorable tidal and bottom relationships as well, farm productivity is not satisfactory.


The cost of such a manager could be equivalent to the local costs for a non-college-graduated school teacher. Farm maintenance can be improved by removing heavy growth of epiphytes, such as Enteromorpha green algae. In Handbook of water soluble gums and resins. 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.

Collect1 1 4: Russell found that where corals and algae had rubbed together due to water motion, the corals more often grew around the seaweed than visa versa. Similar Articles in this Journal. Burman Heterotypic Synonym s Fucus muricatus S. Navy Hydrographic Office, world atlas of sea surface temperature.

Thus, since materials move into and out of algae such as Eucheuma by diffusion, their growth increases as water motion increases, up to the point where drag or force produces excessive physical damage.

Gmelin Weber Bosse Weber-van Bosse and Doty provide some of the structural details of the section Cottoniformia but they are still largely undefined anatomically.

Because of the differences in post-harvest treatment washing in freshwater is conditional for use as food and detrimental to carrageenan quality farmers determine which part of the crop is available for each commodity. Basically it is a multiaxial filamentous red algal genus which becomes strongly pseudoparenchymatous. In the Philippines, a good temperature for the growth of K.
