Canadian Journal of Microbiology A nearly ten-fold decrease in wild crop density, seemingly related to over-harvesting, appears to have taken place Table 3 in Doty at least at one time in the Sulu Sea area. A great deal of community composition information, including the masses of other seaweeds found in the random ring-toss samples, is available in the same data report eucheuma spinosum in Kraft eucheuma spinosum, a similar raw data report.
There is almost nothing more, either published or in the grey literature on the commercial species comparable to that published on E.
Kraft does describe E. Kraft provides a wealth of information on the communities in which commercial Eucheuma species occur, based on one or a few observation periods at many Philippine sites over a wide geographic range.
Doty describes repeated observations of the same eucheuma spinosum of commercial species relative to the non-Eucheuma seaweeds at some 31 sites just in the Eucheuma spinosum Archipelago.

These two eucheuma spinosum to be the largest sources of community information on the genus. Farming routines soon result eucheuma spinosum very uniform populations. The very valuable work of Lim et al.
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. Each farming area displays characteristics which are to a large extent the result of field expediency.
eucheuma spinosum Farms nowadays consist Figure 6 of parallel rows of stakes bearing nylon monofilament eucheuma spinosum to which there are tied branches of Eucheuma broken from previous farmed, or from wild crop, thalli.
For good growth the habitat is especially important in reference to bottom elevation, water movement, the nearness and nature of the bottom materials and the pests that may be in the area.
The successful farms are over sedimentary bottoms with the thalli near or on the bottom and where eucheuma spinosum such as those discussed in the following subsections are minimal.

Farmed strains of spinosum and gelatinae eucheuma spinosum not been as closely observed but they seem to have prospered for years. Thallus colors and eucheuma spinosum rates are often considered indicative of the health of a planting.
There is no finished study of the former but it is well known eucheuma spinosum yellowing indicates a lowering of vitality in the red algae. This value, C, may be high due to genetic variability in the population or due to uneven grazing, responses to environment, different ages of seedstock branches orientations and exposures of the thalli.

The lack of healthy growth, very low rates of growth and lack of reproductive eucheuma spinosum may be due to environmental imbalances or agronomic practices. It must be recognized that farms are often located where Eucheuma does not occur naturally, and this may not always be just due to a lack of suitable substratum.
The major cottonii form, tambalang, may not become fertile on farms, though the typical eucheuma spinosum is freely fertile in its native habitat.
