“…These demonstration farms provided the seedlings for E. denticulatum and built the capacity of the community, who were identified as pioneers for seaweed farming in the country (Nyonje et al 2013-unpublished). According to Mirera et al (2020), the effort increased seaweed production from less than 10t (FW) in 2008 to above 450t (FW) in 2017.…”

“…The seaweed farmers' group also worked, with the Kenyan Industrial Research and Development Institute and other agencies, to develop various other cosmetic and food products, minimise post-harvest losses and introduce other aspects of best management practices (Nyonje et al 2017-unpubl.). With the growing interest in seaweed farming from a range of stakeholders and with the socio-economic benefits for the local communities having been demonstrated (Mirera et al 2020;Odhiambo et al 2020), the government of Kenya identified this industry as one of the priority interventions under the Blue Economy Initiative (Blue Economy Committee Report 2016-unpubl.). Subsequently, the government is planning to map the entire Kenyan coastline for suitable sites for seaweed farming and to develop the industry value chain (Blue Economy Committee Report, 2016-unpubl.).…”

Global demand for seaweed and its products has increased exponentially over the last 25 years. Equally, the continent of Africa and its offshore islands have considerable potential for seaweed production to contribute to world demand. Compared with China and the rest of Asia, Africa lags behind in seaweed production and utilisation. However, for red eucheumatoid seaweeds, Africa is the third-largest producer in the world, producing about 120,000 t (FW) annually. Details are provided for 13 African countries that are currently involved in seaweed farming and harvesting, commercially or experimentally, for export or domestic utilisation. Eucheuma spp. and Kappaphycus spp. in Tanzania represent 92% and in Madagascar 4.7% of continental production, and Ulva spp. and Gracilaria spp. in South Africa represent 1.5%. Over 2000 species of seaweed have been recorded in Africa, some of which are already successfully cultivated in other parts of the world. The environmental conditions across the continent range from warm, tropical waters to the cooler, nutrient-rich waters of the southwest, enabling the cultivation of seaweeds from the tropical, carrageenan-producing eucheumatoids to temperate kelp species. Seaweed aquaculture production in Africa, led predominantly by women, has improved the livelihoods of its coastal people. Challenges through disease and pest outbreaks, as a result of climate change, and the low prices paid to farmers are highlighted as major constraints on the development of this industry. Through scaling up and expanding current efforts in production and utilisation of seaweeds, Africa has the potential to join China and Southeast Asia as a global leader in producing, processing and consuming a wide variety of seaweeds.

“…Rumput laut telah menjadi sumber mata pencaharian alternatif utama bagi sejumlah penduduk pesisir di negara berkembang termasuk di Indonesia (Mirera et al, 2020). Indonesia adalah penghasil rumput laut tropis utama di dunia dengan sekitar 70.000 keluarga tergantung pada aktivitas budidaya rumput laut.…”

“…Sekitar 60-80% dari produksi agar-agar dunia bergantung pada ketersediaan Gracilaria sp (Wang et al, 2015). Budidaya rumput laut memiliki dampak lingkungan yang minimal terhadap laut dan berpotensi berdampak positif pada kesejahteraan masyarakat pesisir jika pengelolaannya dilakukan dengan benar (Mirera et al, 2020). Keluarga petani rumput laut di Sulawesi dapat menghasilkan 100 juta per tahun, dan petani rumput laut dengan petak tambak luas bisa mencapai 200 juta per tahun.…”

This study is survey research that aims to evaluate the feasibility of ponds for the cultivation of Gracilaria sp. The number of sample points is 6 determined by using a purposive sampling method based on the location and source of water of the pond in Tellu Siattinge District, Bone Regency. Measurement of physical-chemical parameters each station I, II, III, IV, V, VI showed that temperature of 34, 32, 32, 31, 32, 31 ° C, depth of 40, 47, 45, 45, 50, 52 cm, brightness of 87, 85, 73, 78, 60, 63%, water pH 6.5, 7, 6.5, 6.5, 7, 7, dissolved oxygen (DO) 4.1, 2.6 , 7.8, 3.5, 2.1, 3.5 ppm, salinity of 14, 16, 20, 21, 25, 25 ppt, phosphorus content 0.017, 0.015, 0.018, 0.023, 0.014, 0.021 ppm, nitrate levels 0.011, 0.15, 0.29, 0.021, 0.011, 0.023 ppm, bottom of the pond are clay except station VI with clay loam, and all ponds locations sheltered from strong winds and strong waves. The result of the study showed that station II, III, IV, and VI are classes S1 (suitable), whereas at the station I and V are classes S2.

“…In 1985, there were 118 species of red algae, 80 species of green algae, and 36 species of brown algae. Seaweed farming has developed into another source of income for coastal communities and small-scale fishers (Mirera et al, 2020).…”

The purpose of this research is to conduct a marketing and revenue analysis of seaweed producers. This study takes a qualitative approach via the use of exploratory research techniques. This research included all farmers who grow seaweed. The Slovin formula was used to calculate the sample size, which was 40 heads of households. The sample is determined using a basic random sampling technique. While data gathering is accomplished via interviews, observation, and documentation. Farmers market their seaweed goods in two ways, first to middleman merchants, then to collectors, and lastly to inter-city traders. Second, farmers sell their produce to collectors, who subsequently distribute it to intercity merchants. The average revenue earned by seaweed growers. That is 6 USD –830 USD in a single manufacturing process, indicating that seaweed farming is lucrative and possible to expand, but that production expenses must be more efficiently used to achieve larger profits
