Crayfish parties

by Sven Olof Malmqvist

It is one thing to write a column in an aquaculture magazine and an entirely other thing to be a practical grower of any aquatic species.

Years back I put a number of crayfishes (a form of fresh water lobster) in one of my ponds. It is vital that you have a constant inflow of fresh water and, of course, an outlet so there is sufficient circulation and oxygen.
 


The pond isn’t that big and deep but is brimming with stones and hideouts, which are needed when the crayfish exuviate their shells and are vulnerable to attacks by their own sort. Nature is cruel!

Anyway, I have been fishing every autumn when you are supposed to eat them but so far I have thought they are too small and have thrown them back again.

In Scandinavia we normally go out in the night placing cages in the water. As bait one can use fresh meat, chicken or fishes as cray fish aren’t picky about their food. The next morning you pick them up and empty the catch.

You boil crayfish in really hot water, together with dill, sugar and beer, and then let them cool down.

You eat them cold as is, preferably sitting outside as it is rather messy, as you eat them with your own hands, so you need to cover your clothes to protect them. Shots of aquavit and many glasses of beer will also play an important role in this crayfish party.

Exploring ISAAH

by Dr Neil Auchterlonie, Technical Director, IFFO

Last week I was lucky enough to attend the International Symposium on Aquatic Animal Health (ISAAH), held in Charlottetown, Prince Edward Island Canada. This event, held on a four-year cycle, draws aquatic animal health professionals from across the world.
 

The Symposium ran over the whole week, with many different sessions, and there was a great diversity of fish species discussed, reflecting the growth in aquaculture over time. As well as the usual suspects of the modern aquaculture industry, there were even special sessions devoted to the health of cleaner fish, ornamental fish, and zebra fish (for laboratory studies), so it really was all-encompassing in terms of the coverage of subject matter.

I was not attending the Symposium out of personal interest though, nor was I on holiday, even though Charlottetown appeared to be a very picturesque location, and worthy of some time spent as a tourist.

IFFO had submitted an abstract in order to provide a technical presentation within one of the sessions, the QASH project session. QASH is an acronym that stands for Quantitative Atlantic Salmon Health Assessment, and the project is a collaboration between scientists in Norway, Scotland, Chile and Canada, led by Prof Karin Pittman of the University of Bergen. The aim of QASH is to develop tools that permit rapid and accurate measurements of farmed salmon health, indicating very strong real-world applications of the research.

Within salmon farming there are some clear health challenges, often linked directly to pathogens such as sea lice, piscirickettsia, gill amoebae, salmonid alphavirus. The session was split into three, focusing on biomarkers, barriers and stressors, and available toolboxes, with some lively discussion at the end.

My IFFO paper focused on the link between nutrition and health in farmed salmon, exploring the changing profile of salmon feeds over time and the nutritional variability that has resulted. None of this is earth-shattering in terms of the messages and many are aware of the substantial progress that has been made in the substitution of marine ingredients over time.

That research has largely been undertaken by the feed companies, responding to market competition over time with their changing formulations. Much of this research is understandably commercial and confidential. Although some of the information has reached the public domain, the majority has not.

The Salmon of Knowledge

by Ioannis Zabetakis

Once upon a time (in one of my beloved Celtic stories), Fionn mac Cumhaill, the great leader of the Fianna of Ireland, was still a young boy and he was sent to live with a very wise man named Finnegas.  

Finnegas was a poet who lived on the banks of the river Boyne and was renowned throughout Ireland for his vast knowledge. As well as being renowned for his skills in composing and reciting poetry, Finnegas knew more about the ways of the world, including the secrets of the birds and animals and plants and stars, than any other man in Ireland. It was because of his vast knowledge that Fionn had been sent to learn from Finnegas.

Fionn loved to listen to the old man’s wonderful stories and his many words of wisdom which he too, in time, would learn to recite. In exchange for the wisdom Finnegas would pass on to him Fionn would help with house chores like cooking and cleaning, but also fishing for the old man.

However, despite Finnegas’ vast knowledge, he did not know everything and there were times when Fionn’s endless curiosity got the better of him, and he was left unable to answer the young boy’s questions. ‘Is there a way to know everything?’ Fionn asked him.

This was a question that Finnegas had asked once too and was the very reason why he now lived next to the river Boyne. It had been told by the druids of old that living in a still, dark pool in the shade of the overhanging hazel trees was the Salmon of Knowledge. It was as result of eating the nuts of these magical hazel trees that the salmon had acquired all the knowledge of the world. And so it was, that, according to prophecy, the one who would eat the salmon would gain the knowledge for themselves.

Finnegas had been living on the edge of the river for several years now, attempting to catch the salmon and gain such wisdom. And the story goes on…and we still do not know if Finnegas has been successful in his pursuit of the Salmon of Knowledge.
