Seaweed blue carbon: Ready? Or Not?NARA Subscribed
Gracilaria aquaculture is one of the fastest‐growing sectors, contributing to 10.5% of the global seaweed feed‐stock supply chain in 2019. It predominantly caters to food‐grade agar, animal feed and non‐food sector applications viz. biotechnology, biomedical and pharmaceuticals. It has witnessed a rapid expansion triggered by increased demand due to commodity trade. Biosecurity‐related issues are the key factors constraining i...
Overview of 3 year precommercial seafarming of Macrocystis pyrifera along the Chilean coastNARA Subscribed
Chile is one of the main producers of seaweeds in the world; however, most of the production comes from harvesting natural beds and only 2.4% from cultures, dominated by the agarophyte Gracilaria chilensis . One of the most exploited resources is the giant kelp Macrocystis pyrifera , which is sold fresh for abalone feed and dry for alginate extraction. Recently, new possible markets are developing for this species, for example...
Growth, production and biofiltration rates of seaweed, Ulva lactuca were investigated at two stocking densities (3 kg and 6 kg m −2 ) and two effluent flow rates (5.4 and 10.8 m 3 day −1 ) to optimize an integrated mariculture system at Saudi Red Sea coast. effluents from fish‐rearing tank, stocked with 200 kg fish ( Oreochromis spilurus ), fed to six seaweed tanks via sedimentation tank. Fish growth (weight gain 1.75 g fish d...
Antimicrobial resistance and antimicrobial resistance genes in marine bacteria from salmon aquaculture and non‐aquaculture sitesNARA Subscribed
Summary Antimicrobial resistance ( AR ) detected by disc diffusion and antimicrobial resistance genes detected by DNA hybridization and polymerase chain reaction with amplicon sequencing were studied in 124 marine bacterial isolates from a C hilean salmon aquaculture site and 76 from a site without aquaculture 8 km distant. Resistance to one or more antimicrobials was present in 81% of the isolates regardless of site. Resistan...
