“…Nevertheless, vegetative propagation does not augment genetic variability which may contribute to the decrease in growth rates and carrageenan yield and the increased susceptibility to diseases observed in some locations (Hurtado & Cheney, 2003). Current research is aimed at optimizing culture conditions for the massive production of high-quality lab seedlings (Yong et al, 2014). If these efforts are successful, the industry could eventually turn away from repeated vegetative propagation and experience overall increases in productivity.…”

& The farming of the red seaweed Kappaphycus alvarezii and related species as raw material for the hydrocolloid carrageenan rapidly spread from the Philippines in the late 1960s to Indonesia, Tanzania, and other tropical countries around the world. Although numerous studies have documented positive socioeconomic impacts for seaweed farming, factors such as diseases and distance to export markets have led to an uneven development of the industry. Using standard budgeting techniques, this study adapted production and market data from a FAO-led global review of seaweed farming to develop comparative enterprise budgets for eight farming systems in six countries (Indonesia, the Philippines, Tanzania, India, Solomon Islands, and Mexico). Although the basic technology package is the same across countries, the study revealed large differences in the economic performance of systems due to wide variations in farm prices and the scale of operations. Although seaweed farming is a suitable activity for small-scale producers, a minimum of 2,000 m of cultures lines are still necessary to ensure adequate economic returns. Greater farming plots may be needed if farm prices are well below the average farm prices paid in Indonesia and the Philippines. Policy recommendations are made to improve the economic potential of underperforming systems.

“…Positive response with the addition of phytoregulators has been reported earlier (Hayashi et al, 2008;Yong et al, 2014a). Phtyoregulators, auxins and cytokinins affect growth in red seaweeds (Jennings, 1971;Fries, 1974;Fries and Iwasaki, 1976).…”

“…Positive responses with use of PGRs in some seaweed species have been reported by earlier researchers (Kaczyna and Megnet, 1993;Yokoya et al, 2004;Hayashi et al, 2008;Yong et al, 2014a). Report by AguirreLipperheide et al, (1995) also suggested that red seaweed species respond more to exogenously supplied PGRs than other seaweeds.…”

In seaweed Eucheuma cottonii cultures, a water carrying capacity is an important factor to optimize the seaweed culture. Carrying capacity can be determined by an ecological footprint production (EFp) analysis. This research was conducted in May 2015 (1st transitional season) and September 2015 (2nd transitional season) in Luwu and Palopo distircts, South Sulawesi. Map and land use were analyzed using GIS (Geographic Information Systems). The result showed that the ecological foot-print production (EFP) in Luwu waters was 67.88 ton/capita/year or equivalent to 235,823.93 tons/ year. However, based on the analysis of the water availability for seaweed was 59,781.79 hectares, it can produce seaweed (biocapacity) for 1,437,779.60 tons/year and the number of farmers that allows for use the waters is 21,432 capita. The ecological footprint production (EFp) in Palopo waters is 3.08 ton/capita/year, or equivalent to 4,589.99 tons/year. Water availability analysis is 1,771. 41 hectares are able to produce seaweed (biocapacity) for 18,287.46 ton/year and the number of far-mers that allows for use the waters is 635 farmers capita. The results comparison between biocapa-ci-ty and ecological footprint, ecological status for Luwu and Palopo waters are still in sustainable use.
