I write this editorial from my hometown of Llanelli under a cloudless blue sky and a beautiful warm summer’s day. It’s a reminder of rising temperatures in Europe and the need to be aware of the potentially lower oxygen levels in our fish culture operations and the need for aeration and supporting technologies to optimize conditions for very sensitive fish such as trout.
The farming of rainbow trout is often featured in this magazine and is globally an important fish actually my favorite by far compared to salmon. The trout is such a versatile fish and can be found throughout the UK having adapted to varying conditions and is so underrated in many ways.
I was brought up to appreciate this species having fished my river for wild brown trout with so many expeditions with my father in my youth. Wild brown trout has a wonderful flavor and excellent eating qualities with its white flesh and nutritious value.
The rainbow trout for me is a tastier fish than farmed salmon but we have some challenges to improve its image to the consumer with respect to appeal as an easy but bony fish to cook and serve. Sadly, so many trout farmers have closed down their farms in the UK due to financial pressure and the industry has diminished someway in the last decade compared the boom years when fish farms were more abundant.
When I was first in my old institution in Plymouth there were at least least five farms in close proximity to Plymouth in Devon that supplied fish for my feeding trials. Now only two farms with fingerling trout sources are available in the other neighboring counties of Somerset and Dorset. It was getting increasingly very difficult to obtain fish for studies and I am sure this trend will continue to impede procuring of good quality fish for research in the future.
The SW of England is more renowned for its shellfish farming than finfish aquaculture so perhaps fate has allowed me greater opportunities in new regions of the UK to restore an aquaculture research base of international class as my final legacy before I retire one day.
One thing about my new position at Harper Adams University is my chance to read more and get into scientific papers in depth. I also get to meet new contacts from industry and the agri-tech sector that is becoming more interested in aquaculture within the UK.
We need this to stimulate the concept of urban and city aquaculture enterprises through the developments in RAS (Recirculation Aquaculture Systems) and Aquaponics installations. We see this happening in London and in Holland with great potential to expand throughout the world. I would hope to report on such aquaculture technologies in future here with some excellent examples.
In the meantime our latest issue is packed as usual with news features and topical reports varying from technical developments to the more scientific level.
The summer issue of the magazine contains articles with a much keener focus than usual on the world of fish farming technology, as well as some fine reporting from the recent Aquaculture UK show in Scotland.
As well as the event reporting, we also have our usual array of contributions from our expert columnists as well.
Seabream is this edition’s species focus, with articles also focusing on Digestable energy, micro-algae and water disinfection with ultraviolet light. We also have a very interesting article about AKVA’s new net cleaning ROV. Continuing our fish farming technology theme, BOC’s Stefan Dullstein is this month’s interviewee.
In the next issue I will have celebrated (If that’s the correct term!) 30 years of continuous service in academia and achieved so much with the help of so many over an extremely interesting period of my life and more recently, unexpected challenges too. It has been an interesting three decades having learned so much about this dynamic and ever changing industry.
There is an ever-increasing amount of information to assimilate and I am pleased that this magazine continues to play a leading role and voice within its specialised field.

International Aquafeed reflects a passion for aquafeed and excitement about new technology. Our objective is to be a respected provider of information about aquafeed in the widest sense.
Feed makes up around 70 percent of the cost of producing farmed fish. In each issue, we take an in-depth look at a wide range of technical issues associated with aquafeed production and use. We bring our readers global news about new technology and research, feed ingredients and micro-ingredients, market trends and all issues that impact on the aquafeed supply chain today and tomorrow.
We have a deep commitment to our readers and our advertisers. We believe in quality information and quality design, just as you believe in the quality of your products.
