“…167 Traditionally, the grow-out phase in commercial scale aquaculture of Ulva takes place in open waters, where seeded nets are cultivated on poles fixed in shallow, calm oceanic or estuarine waters with periodical exposure to air at low tide. 88 Tank-based cultivation methods have been established or experimentally validated for several Ulva species using a variety of different methods including: U. prolifera using the 'germling cluster method'; 86 U. tepida in outdoor tanks attached to ropes at 10 cm depth 89,168 or free floating attached to free-floating 'bioballs'; 167 Ulva spp. in large-scale raceways using paddle-wheels for water recirculation; 39 U. ohnoi in free-floating in fibre-glass parabolic tanks (10,000 L) receiving nutrient-rich water from barramundi (Lates calcarifer, Bloch 1790) hatchery; 169 U. compressa using a drip-irrigation system; 170 U. rigida in concrete tanks (20,000 L) in free-floating conditions using nutrient-rich effluent from fish farm in IMTA; 40 U. lactuca free floating in tumble culture, 171 or in pilot scale photobioreactors.…”

Green macroalgae (Chlorophyta) currently represent a residual fraction (<1%) of global seaweed biomass production landings. In turn, red (Rhodophyta) and brown (Ochrophyta) macroalgae dominate the remaining percentage of aquaculture production, exceeding 32 million tonnes per annum. However, the industry relies on a relatively low number of species, in which as few as seven macroalgal genera collectively represent the bulk of global production metrics. At present, innovation and increased sustainability of the industry calls for diversification of macroalgal species/strains in aquaculture to counteract potential adverse effects ensuing from genetic impoverishment, decreased resilience to disease and climate change. Despite the dominance of red and brown seaweed regarding production figures, aquaculture of green macroalgae has witnessed an increasing trend in productivity and diversification over the last decades, particularly in Asia, where green seaweed taxa often occupy specific market niches in the food sector. Furthermore, growing interest in green seaweeds in aquaculture has been highlighted for different applications in emerging western markets (eg IMTA, biorefineries, food delicacies), owing to a unique diversity of cytomorphologies, ecophysiological traits, propagation capacities and bioactive compounds featured by this group of macroalgae. Cultivation technologies are relatively well developed, but sustainability assessments are scarce and required to unlock the potential of green seaweeds. Although it is likely that green macroalgae will remain occupying specialised market niches, in which high‐value products are favoured, we argue that aquaculture of chlorophytan taxa presents itself as a compelling option under the current quest for commercial diversification of products and expansion of the sector.

“…The application of macroalgal fractions as functional ingredients for dietary consumption has attracted significant attention in recent years, and studies have explored novel approaches in the biorefinery of green macroalgae with the inclusion of additional proprietary steps targeted at the mineral (salt) content of green macroalgae. Macroalgal salts have been considered to be associated with a healthy balance of vital minerals required for human nutrition, particularly since they contain high proportions of potassium and magnesium, with favourable sodium to potassium ratio features that can prevent hypertension and cardiovascular disease [119,120]. The works of one particular group have highlighted the prospects of incorporating an initial fresh water washing treatment as a first step in a cascading biorefinery for natural salt fractionation, and how subsequent residues can be valorised for additional bioproduct generation that include the polysaccharide ulvan and proteins [121][122][123].…”

“…The plants were harvested after 14 days, leaving 1cm lengths for the next growth cycle. The specific growth rate decreased from the 2nd (15.6 ± 4.2 % day -1 ) cycle to the 3rd (10.4 ± 8.0 % day -1 ) cycle; and two harvest was recommended (Carl et al, 2016).…”

A Grand Challenge programme was initiated at the University of Malaya under the Equitable Society Research Cluster, to introduce seaweed farming to the coastal communities at Bachok district, Kelantan. Cultivation trials of selected commercial seaweeds like Kappaphycus (source of carrageenan), Gracilaria (source of agar), Gelidium (source of agar and pulp) and Ulva (salad) will be conducted using onshore and offshore systems, and the data collected is used for the techno-economics analysis. This paper discusses the techno-economics of various cultivation systems, as well as the importance of community empowerment, as a guide to the formulation of a roadmap for the integration of seaweed farming into the Bachok coastal communities. Abstrak Satu Program Grand Challenge telah dimulakan dibawah Kluster Penyelidikan Equitable Society di Universiti Malaya bagi memperkenalkan pengkulturan rumpair laut kepada komuniti persisiran pantai di daerah Bachok, Kelantan. Percubaan pengkulturan rumpair laut terpilih seperti Kappaphycus (sumber carrageenan), Gracilaria (sumber agar), Gelidium (sumber agar dan pulpa) dan Ulva (salad) akan dilaksanakan dengan menggunakan sistem tepi pantai (on-shore) dan luar pantai (off-shore), dan data-data yang dikumpulkan ini digunakan dalam analisis tekno-ekonomi. Makalah ini membincangkan teknoekonomi bagi pelbagai sistem pengkulturan serta kepentingan pemberdayaan komuniti, sebagai panduan kepada perumusan pelan hala tuju untuk mengintegrasikan pengkulturan rumpair laut ke komuniti pesisiran pantai Bachok.
