Today
International Aquafeed attended a series of six conference at Aquaculture UK
2014, hosted by Novartis, featuring talks by PhD and Masters students from
Scottish universities.
Their
research touched upon important aquacultural topics and all were competing for
the chance to visit Prince Edward Island, Canada, the home of Novartis' fish
vaccination centre.
And IAF
can announce the winner of the Aquaculture UK 2014 Gala Dinner and prize giving
ceremony which has just come to an end! By coincidence it was the presenter we
had listened to and decided was the most appropriate for us to report on here.
The
winner is Ms Marie Smedley and we present here a brief synopsis of her
presentation which was a particular highlight for us.
Entitled
'Nutrition as a tool to improve performance in Triploid Atlantic salmon (salmo
salar) in freshwater and seawater production' - by Marie Smedley, Institute of
Aquaculture, University of Stirling.
Marie
is completing a PhD study into Atlantic salmon Triploids. Sponsoring this study
were Biomar and Marine Harvest Scotland.
Triploids
are sterile fish which have three chromosomes in their genetic make up and can
be seen as sustainable to farm commercially. The fish are still not perfect
because they display reduced tolerance to sub-optimal environments, she told
her audience.
However,
she understands that it is not a sustainable solution in terms of cost to farm
on a larger scale.
Marie
believes that Triploids and phosphorus to be a winning combination; she
explained to us that their phosphorous requirement must be met from the diet
and cannot be met by freshwater or seawater environments.
Bactocell
- a product from Lallemand - was also used and had a positive effect on
mitigating malformation development of vertebrae and jaw growth and was used
after phosphorus.
Triploids
in the study grew faster in general as opposed to the diploid salmon. The
growth was marked after the first four months, then it was 20-30 percent faster
in freshwater and 10 percent faster in seawater, compared to normal diploid
fish and normal conditions
Tomorrow
is the final day of Aquaculture UK 2014 at the MacDonald Resort in Aviemore.
It's been an eventful day in this beautiful part of Scotland!
