Biofilters are commonly used in recirculation aquaculture systems (RAS), but their limitations mean that innovators are busy developing possible alternatives – such as electro-oxidation – or enhancements, such as electro-coagulation and UASB reactors.
Dr Andrew Whiston, a marine biologist and aquaculture innovator, is attempting to revolutionise RAS technology with a system based on one founding principle - maximum efficiency and minimal waste.
While there are still a number of challenges to overcome, a number of innovators in the Philippines believe that cultivating Ulva has long term potential at a time when diversification of the country’s seaweed sector would be welcomed.
David Gebhard, co-founder of the up-and-coming shrimp producer AquaPurna, talks about the development of the company's new commercial site which will employ innovative RAS technology to provide European markets with locally-grown shrimp.
With two of the key international aquaculture welfare standards currently being updated, and the topic being more prominent in the mainstream media, two experts on the subject share their views.
A new report has recently been published as part of Project Madoc – a scheme that aims to significantly increase the output of the seaweed sector in Wales.
India’s seaweed sector is dominated by the production of Kappaphycus for the hydrocolloid and biostimulant industries, but Gabriella D’Cruz, founder of The Good Ocean, is determined to diversify the species grown and the applications for these.
In the face of rising mortality rates caused by warming sea temperatures, Saumon de France - Europe's most southernly net pen salmon producer - has had to significantly modify its production cycle, and is looking to expand both offshore and onshore.
Brilliant Planet’s unique idea to capture carbon by creating – and then burying – algal blooms in coastal deserts shows great promise, but it will take hundreds millions of dollars of investment before it can fully achieve its ambitious goals.
Given the decline of wild stocks and surging consumer demand, the case for farming sablefish has never been stronger. However, challenges – in particular relating to growth rates – have meant that few producers of this prized species have achieved commercial s…
