Feed attractants in aquaculture - the chemical composition of aquacultured Ulva lacinulata (Chlorophyta)
… two decades, cultivation of the green seaweed Ulva lacinulata (Ulvales) has proven to be commercially viable and an integral part of the South African abalone aquaculture industry. This seaweed is not sold, but mainly used as feed for the abalone Haliotis midae (Lepetellida) and on some farms …

Microbiome associated with Ulva lacinulata and seawater in an integrated abalone (Haliotis midae)–Ulva system with partial recirculation
… commercial abalone farms in South Africa grow Ulva in D-ended raceways to bioremediate farm effluent water, allowing water to be recirculated back to the abalone, while Ulva is often used as a supplementary feed source. Despite Ulva's versatility in integrated multi-trophic aquaculture (IMTA) …

Ulva as a functional feed: a practical investigation into the effects of Ulva lacinulata on the growth, consumption, health and gut microbiota of the farmed abalone Haliotis midae
… adoption of cultivation of the macroalga Ulva by the South African abalone aquaculture industry using IMTA systems. Farms that use fresh Ulva as a supplement to formulated feed have reported a reduction in the volume of formulated feed required to achieve optimal growth of abalone however, …

Determining larval settlement, post-settlement and weaning substrates and regimes for the sea urchin Tripneustes gratilla in intensive aquaculture
… and the timing of weaning onto macroalgae (Ulva lacinulata). Experimental substrates tested include: Ulvella lens, fresh Ulva, dried Ulva and alginate, dried Ulva and agar, Nitzschia sp. (undescribed diatom), dried Isochrysis galbana and alginate, probiotic Vibrio midae SY9 and alginate, V. …

The feasibility of a commercial-scale recirculating aquaculture system integrating sea urchins (Tripneustes gratilla) and seaweed (Ulva)
… Tripneustes gratilla, and the green macroalga, Ulva, could be suitable co-candidates for a land-based recirculating Integrated MultiTrophic Aquaculture (IMTA) system. This IMTA system is suggested to be sustainable and efficient, primarily because the Ulva would simultaneously provide …

Characterization of Ulva (Ulvaceae, Chlorophyta) species cultured in commercial abalone farms in South Africa, and comparison with closely related wild species, using morpho-anatomical and molecular methods
… of species cultured in South Africa, with Ulva species cultured at a commercial scale. In South Africa, the annual production of Ulva is approximately 2000 tonnes (wet weight), with the majority of Ulva being grown in landbased paddle raceway systems receiving abalone effluent water. …
