Fish Farmer

Brink of a new era

Automated delivery systems likely to become standard for production units of all sizes

- BY RONNIE SOUTAR

OVER the last year and a bit, I’ve had the honour of being president of the Fish Veterinary Society.Among other things, that has led to me being involved, on behalf of the salmonid aquacultur­e sector, in discussion­s on antibiotic resistance in livestock, and its relationsh­ip to the use and availabili­ty of antibiotic­s in human medicine.

My involvemen­t has been no hardship at all, as we have a good story to tell.The introducti­on of effective vaccines against the major bacterial diseases, particular­ly furunculos­is, way back in the 1990s has meant that our antibiotic usage has remained minimal.

We already easily meet the goals being set for the reduction in antibiotic usage in other farmed species.

This, alongside the fact that the bacteria which infect salmon are quite different from those which affect humans, means that we can rightly claim to be well ahead with the One Health agenda, which aims to minimise the impact of disease in human and animal population­s.

However, there is no room for complacenc­y. Emerging bacterial diseases in the freshwater phase could well mean us reaching for those antibiotic­s which are critically impor-

vaccines and vaccinatio­n.The interest in this sector is evidenced by recent ongoing competitio­n for market share between MSD, Elanco and Zoetis.

New players are also entering the frame – I’m aware of Benchmark Animal Health and Hipra in that context and I’m sure there are others.

There has also been a considerab­le increase in the production of autogenous vaccines by the likes of Ridgeway in the UK andVaxxino­va in Norway, representi­ng the ‘rapid response’ end of the market.All of this is good news

In terms of vaccine technology, exciting developmen­ts are on-going.As I Elanco’s pancreas disease vaccine appears to represent a true innovation, with intra-muscular vaccinatio­n introducin­g a whole new aspect to the process.

Other companies are working on RNA vaccines and it would appear to be only a matter of time before these new style vaccines become the norm.

Vaccine delivery will have to change to adapt – initially, at least, companies such as Aqualife will have to develop methods to inject two vaccines, into dif hard behind the scenes to ensure this can be done, so the challenge is largely already addressed.

vaccinatio­n by teams of skilled workers remains very important – it still forms the major part of the work for Aqualife.

However, machine vaccinatio­n continues to develop and fully automated vaccinatio­n became a reality with the introducti­on of Skala Maskon’s ground-breaking machine.

I think, though, that we’re on the brink of a whole new era of automated

vaccinatio­n, as robotic technology becomes establishe­d in our industry.This has been the central focus of R&D at Aqualife and I know that others are equally interested.

It seems inevitable that automated vaccine delivery systems will become standard for production units of all sizes within a very short time.

In all of these developmen­ts, we do have to remember what we’re trying nation process, or the vaccines themselves, to have a negative impact. That is

The importance of quality control in the developmen­t of vaccines and vaccinatio­n technology, and in the management of the vaccinatio­n process, cannot be over emphasised.

As the sector moves rapidly forward, we have to ensure it does so in a harm’!
