“…This lack of specific information prevents any conclusion regarding the influence of environmental conditions on the viability of H. musciformis culture viability. The growth rate reported by Camacho, although lower, may be comparable to open-sea cultures developed in Bangladesh (3.2%) [101] and, to a lesser extent in Brazil (5.7%) [102] and India (7.6%) [103] showing the potential of Santa Marta for the establishment of H. musciformis cultures. In the same way, Molina and Álvarez [91] and Rincones and Moreno [97] cultivated Gracilariopsis sp.…”

Colombia has a diverse range of marine ecosystems in the coastal and insular areas of the Caribbean Sea and the Pacific Ocean. Seaweed research has focused mainly on the identification and taxonomic distribution of 628 species identified so far, mainly in the Caribbean Sea. Among the most widely cultivated genera of seaweeds in open-sea pilot systems in Colombia are Hydropuntia, Gracilaria, Hypnea, Kappaphycus, and Eucheuma. These genera have shown low yields as a consequence of high tissue fragility, epiphytism, sedimentation, and nitrogen deficiency. In addition, the evaluation of the biological activity of selected seaweed compounds has advanced considerably, focusing on their composition and their use for direct consumption by humans and animals. Despite the diversity of seaweeds, as well as certain technical and scientific advances, Colombia is still lagging behind other countries in seaweed exploitation, both in Latin America and worldwide. This current status raises the need to increase research, technological (agro-tech) appropriation, and the adoption of effective public policies that will boost algal businesses. In addition, seaweed cultivation could support the current blue economy transition in Colombia, which could eventually allow the country to enter the global seaweed market.

“…The technology to cultivate H. pseudomusciformis was developed recently, and a patent has been claimed on the Brazilian National Industrial Property Institute (INPI) (Valenti et al, 2019). The culture of this macroalgae was performed using a modified module system of long-lines (Pereira et al, 2020). Each module consists of a main polypropylene braid rope with a length of 1 m and with a diameter of 1 cm and is laced with a shredded rope of 30 cm for fixing seedlings of the macroalgae.…”

Simulations were performed to evaluate the economic potential of farming the seaweed Hypnea pseudomusciformis in two production scales for the carrageenan, human food, and glycolic extract markets in Brazil. The initial investment was low in all scenarios (US$25,579 in 7.5 ha and US$71,202 in 22.5 ha farms). Labor and taxes were the major production costs for production commercialized for the carrageenan and human food markets, respectively. Liquid glycerin and bottles were the main costs when the productions were marketed for glycolic extract. The carrageenan market showed no economic feasibility. On the other hand, the human consumption market was shown as very profitable, resilient, and highly attractive (IRR was $100%). Marketing the glycolic extract is also feasible and attractive (IRR was $25%) but had lower economic indicators and low resilience when compared to the human food market scenario. Upscaling the production optimized investments and reduced production costs, improving profitability. The plasticity of seaweed enables entrepreneurs to explore different markets simultaneously to increase farm resilience.
