Background Climate change has been associated with fluctuations of environmental parameters such as salinity, which can affect growth rates, quality, and overall health of farmed organisms. Consequently, farming euryhaline fish can be a solution to build resilience of aquaculture to climate change. Euryhaline species can undergo notable physiologic...

It is well known that ozone causes clumping of solids (micro-flocculation), which facilitates their removal by foam-fractionation, filtration, and sedimentation. It was thought that ozone treatment could be effective after drum-filters or even before the drum-filter. Moreover, it is believed that perhaps the application of polymers in the wastewate...

Stable isotope ratios, carbon (δ¹³C) and nitrogen (δ¹⁵N), and fatty acids validated the trophic connection between farmed fish in a commercial nearshore fish farm and sea cucumbers in the Mediterranean Sea. This dual tracer approach evaluated organic matter transfer in integrated multi-trophic aquaculture (IMTA) and the ability of sea cucumbers to...

The survival and growth of the sea cucumber Holothuria poli were assessed during a 12-month field study when cultured at a commercial fish farm in Malta as part of an integrated multi-trophic aquaculture (IMTA) system. Sea cucumbers were cultured directly below a fish cage at 0 m, E0, at 10 m (E10) and 25 m (E25) distances from the cage and at two...

Lake Victoria, regionally important both as a food and income source, is under pressure due to overfishing and severe pollution. Currently, the vast majority of east African aquaculture is open pond based. The adoption of modern, sustainable, aquaculture technologies and practices – in this case study recirculating aquaculture systems (RAS) – will...

Blue Growth is the creation of economic activity and jobs at sea, while multiple use of space makes efficient use of the available sea area by combining industries. Clearly there are many combinations and many value propositions. However, most technologies to date are considered blue sky concepts, with little robust techno-economic analysis demonst...

The project ‘Measures to support small-scale fisheries in the EU Mediterranean waters’ was a 12 months project funded by the European Union (MARE/2014/04-SI2.723876) in 2016-2017. One of the main aim of this project was to facilitate and increase the level of involvement of small scale fishermen in the decision-making processes by exchanging experi...

Aquaponics is a modern and sustainable food production technology. This paper reviews different policies relevant to aquaponics in order to create a clear picture on how aquaponics can contribute to achieving European goals and how the policies and strategies can provide support and opportunities for this sector. Because aquaponics falls into fish...

Aquaponics is a rapidly emerging agricultural practice, which combines recirculating aquaculture systems (the RAS technology) with the soil-less (hydroponic) cultivation of vegetables. The advantages in terms of productivity and efficient use of resources are huge. Aquaponics contributes to the solutions of some of the crucial problems our planet i...

Feeding dried and vitamin C enriched decapsulated Artemia cysts to African catfish larvae increased their growth rate significantly after 6 days over those fed only freshly decapulated cysts. Groups fed with Artemia nauplii had a significantly higher growth during the experiment, although this difference was not considerably important in practice....

The decapsulated Artemia cysts are widely used as a starter diet for fish larvae. The dark brown external layer, the chorion, which can be removed in hypoclorite solution, is indigest ible for fi sh larvae. Ou r aim was to estimate the amount of Artem ia cysts consumed by African catfish (Cla rias gariepi1111s Burchell) larvae during an experimenta...
