Merry Christmas and a Happy New Year!
I have had quite a busy 2 months here at Harper Adams University in my new role as Professor of Animal Nutrition and Aquaculture with so many exciting responsibilities and commitments to fulfill. It’s always a pleasure to lecture to new students and provide new courses and programmes including our prestigious Masters’ Degree in Aquaculture with a strong focus on fish nutrition.
A recent task was to visit the University of Cambridge as a guest speaker to final year students of veterinary medicine and introduce fish health and aquaculture as a special topic, these students were so engaging and keen to know more. I also paid a visit to Bristol University Vet School where I had the opportunity to address a much bigger audience of second year students and as an Honorary Professor at Nottingham, I must also speak to clinical students at all levels.
These students do not have fish biology modules on their curriculum and are quite unfamiliar with the potential for employment and scope for involvement in aquaculture and especially with regard to health management in the industry. They ask some of the most challenging questions and I have to be on my best performance. I am so pleased to be recognised by such world leading universities in the UK with Cambridge still ranking No1.
Whilst in Scotland earlier this year, I had the pleasure of chairing an examination committee for a doctoral candidate working on the feasibility for using insect meal protein in diets for both tilapia and salmon with good success on a small scale. This was a nice thesis and the student passed her Doctorate without problems.
This is one of the nicest aspects of my job and highly rewarding to end 3 hours of interrogation with happy news and a congratulatory handshake.  I have similar duty to perform but this time in public for a German student at The University of Bergen, Norway in December, investigating the effects of triploidy in salmon in production at different phases from fresh water to sea transfer and grow-out.
This project addresses the potential increased stress and abiotic effects in such fish compared to diploids and there is a significant nutritional focus on the risk of developing lenticular cataracts due to deficiencies of the essential amino acid histidine in lower diet specifications. Environmental interactions compounded by elevated temperature effects and osmotic stress as well as hypoxia add to the issues. It makes for an interesting story indeed! 
On the news front, I see that the USDA is investing some US$1.2 million into specific aquaculture programmes for research and development. It is accepted that the US spends US$96 billion on seafood but only generates a fraction of this with imports dominating. Someone must remind incoming President Trump about this problem and whether aquaculture can benefit from even more US investment. Maybe a fish/seafood trade war with tariffs etc. may be a distant prospect but perhaps aquaculture can help make ‘America great again!’ It is encouraging that the President –Elect really enjoys ‘fillet o Fish’ burger so there’s much hope!
I was also intrigued by the new developments at the Leibniz Institute of Freshwater Ecology. There they have constructed a ‘double recirculation’ system for aquaponics to grow both tilapia and tomatoes in an integrated unit for primary experimental purposes with a concept for home based modular arrangements and also for larger facilities.
The whole idea of low ‘carbon foot print’ farming of fish in one’s own backyard and in urban markets and metropolis locations including in office complexes, sky scrapers may be a future for a niche type of fish farming activity. There are indeed many opportunities for aquaculture to expand even on land.
Returning to the present, in this issue of International Aquafeed, as well as our usual in-depth news coverage and cutting-edge relevant articles, this month’s species focus is Tilapia – with a typically insightful article from my esteemed colleague in aquaculture Dr Laxmappa, that examines Tilapia farming in India.
We also take a look at the progress made so far by Diversify, the EU five-year scheme into the discovery of new species of fish.
Staying even closer to home, we have a very welcome contribution from Martin Smith from the Bibury trout farm – in fact located not far from International Aquafeed’s Cheltenham headquarters!
Our burgeoning Fish-Farming Technology section is also becoming yet another of this publication’s useful resources, featuring contributions from VAKI, Yanmar and Sustainable Marine Energy Ltd.
International Aquafeed’s year is then wrapped up very nicely with a fantastic interview with former EAS President Patrick Lavens from INVE. This is the last issue for 2016 as we head into Christmas and the New Year.
As I turn 60 in January, it is a major milestone in my life having now served over 35 years in aquaculture nutrition research and as an academic.
Now, all that is left for me to do for this year is to thank you all for your invaluable contributions, and to wish you a Merry Christmas Season and a very Happy New Year for 2017.Thank you!
