I am writing this letter on the official start of winter in the Northern hemisphere, and with much shorter days and with a low sun casting long shadows here in England.
I spare a thought for friends and colleagues in Norway, working out at the salmon pens under artificial light, feeding the salmon in rather harsher conditions compared to rural Shropshire where I am academically based, and in South West England, where I live.
How things may change in the future as RAS operations develop and AI type technologies advance, allowing us to function indoors in all weathers, with complete control over the environment and the complete fish production cycle. At my university here in Harper Adams we are pioneers of precision agriculture and our prestigious engineering group receive much acclaim for driverless tractors and robotics that will aid in achieving a sustainable future for arable farming and livestock production.
Last month I guest lectured to a large cohort of agricultural engineering second year students, introducing them to the wonders of aquaculture and the great potential for engineering projects and jobs. They were, I believe, very impressed by the new technologies in deep offshore fish farms and the RAS systems being promoted together with the concept of aquaponics. The application of robotics, drones and control/monitoring systems is endless, and I of course am particularly interested in automatic feeders and the use of robots to feed fish more precisely, providing an intelligent machine vision approach to the observation of fish behaviour and condition.
I believe we are on the verge of a revolution in such technologies, allowing even more expansion of land based aquaculture ensuring quality of product and more efficiency and lower carbon footprints.
The expansion of aquaculture continues with the salmon sector expected to achieve a seven percent growth – continuing the upward trends experienced in Chile and Norway during 2017. These countries managed to overcome problems caused by algal blooms and lice levels the previous year. It has been reported that global growth reached five percent better than 2016, which saw productions fall by around seven percent. Hopefully this will continue in 2018 leading to more demand for aqua-feed to meet such demands in the future.
There are interesting opportunities for the salmon feed industry but more pressure no doubt on resources. Research on novel ingredients will therefore be even more important and for other species in line for expansion.
With reasonable growth in 2017, the shrimp industry is also expected to increase production with India, Ecuador and Indonesia, leading other countries in this sector placing further demands on feedstock and hatcheries. My colleague, Kurt Servin is in Mexico, keeping me well up to date on technologies to support the health and quality of farmed shrimp both as a PhD research student and his position with Jefo. Products such as exogenous enzymes will undoubtedly revolutionise the potential of many plant based protein concentrates for both shrimp and finfish.
I also noted that, Europe’s insect producers, including those who are culturing species such as black soldier fly larvae for aquafeeds, held their annual conference in Brussels recently. This event was organised by the International Platform of Insects for Food and Feed (IPIFF) and the meeting emphasised the role insects for food and feed could play in answering global societal challenges. There were many opportunities discussed and the EU policy and legislative framework to maximise this potential. I am constantly being approached by companies in the UK for advice in this area and conducting some trials in Africa to evaluate their potential in several warm water fish species.
There are also new developments in GMO technologies for enhancing the expression of long chain omega-3 fatty acids (EPA and DHA) in various terrestrial plants including canola. This will I’m sure make a positive contribution if we can persuade the consumer on the safety and efficacy of such materials and contemporary molecular based technology. It is not just Atlantic salmon that’s having the GMO ‘make-over’.
All that remains is for me to wish our readers whether you read our hard magazine copy, or on- line a very seasonal greetings as we close on 2017 from all at Perendale Publishers.
A very Happy Christmas and New Year to all! We will return in 2018 when I commence my 10th year as Editor in Chief of International Aquafeed.

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.
