Established in 2005 Falklands Fish Farming is engaged in researching the aquacultural potential of a novel deep sea marine finfish. This is an exciting opportunity to work with the development of a new marine species, in a challenging but rewarding environment.
Few microbial studies in aquaponics, a growing trend in food production, have been conducted to determine food safety status. The aim of this study was to determine the food safety status and the effectiveness of ultraviolet treatment (15 W, luminous flux of 900 lm) as a food safety intervention in reducing the microbial loads of the water system in a model aquaponic unit growing lettuce, basil, and barramundi (Australian Sea Bass). Sweet basil, bibb lettuce, water samples, and fish swabs were collected throughout the 118-day production period, and microbial analysis was conducted in triplicate for the presence of E. coli O157:H7, Salmonella spp., and the prevalence of aerobic plate counts (APC), coliforms, and fecal coliforms in these systems. Absence of foodborne pathogens was confirmed using ELISA technology and enumeration through petrifilms (coliform/E. coli). A significant increase was observed in aerobic plate counts over the trial period (1 to 3 log10 CFU·mL−1) in the presence and absence of UV (p > 0.05). Ultraviolet treatment did not significantly reduce the APC or coliform counts when compared to the control system samples. Future work should focus on improving the unit design, the evaluation of bio-solid filtration, and other food safety interventions.

“Our new facility in Ortnevik is well underway – about 6000m2 is already built and in use, while it will be increased to 10,000m2 by the summer,” Jan Arne Brekke, Sogn Aqua’s CEO, told kyst.no. He notes that there is still some fine-tuning needed at the new facility, but it’s working well, despite being three times […]
Quand les mers et les océans se vident de leurs poissons, les aquaculteurs remplacent peu à peu les pêcheurs. La région Paca compte une dizaine d'installations d'élevages marins. Valérie Simonet est allée à leur rencontre. Diffusion de son film ce dimanche à 12h55. Voir ici extraits et entretien.
Aponix barrels are used as growing component system in an existing nutrient cycle. A barrel can be assembled using 2-3 compact elements. The available vertical space in your growing area determines the number of growspaces of a barrel. It is meant for high density growing >80 plants per square meter.
