Scottish shark research raises concerns about the lack of sharks in Scotland

June 2009. The greatest shark tagging event ever held in Scotland, the UK and probably in the world - was the overall verdict of those who took part in Sharkatag organised by the Scottish Sea Angling Conservation Network (www.ssacn.org).
Two hundred and fifteen anglers of all ages and abilities, coming from as far away as Cornwall and Caithness, attended the event held around the Solway region
in South West Scotland, fishing from boats, kayaks and the shore to catch, tag and release various shark species.
Perilous state of endangered shark species
The event had three goals - to highlight the perilous state of endangered shark species; to start gathering some of the data to support claims for their
protection; to continue to press politicians and fisheries managers to recognise the needs of the sea angling community and its contribution to the Scottish
economy.
Very poor fishing
However the fishing was very disappointing. According to Ian Burrett, SSACN's Project Director, "Around two hundred tope, smoothhound and bull huss
were tagged over the three days and that can only be described as poor compared to what the total should have been.
Lower numbers than expected were caught. Credit Sharkatag.
"It really worries me that many of the tope packs have failed to show this year. The whole region seems to be void of the expected male breeding stock and the fish caught were mostly immature females, typically under twenty pounds and a few solitary females in the 50-60 pound range; Luce Bay was especially poor for the time of year."
Only 3 rays tagged
"Combined with the lack of rays tagged, only three throughout Sharkatag, it shows how urgently plans are needed to help protect and
regenerate the stocks. Twenty year ago virtually every boat would have recorded several mature tope and rays."
Lack of action by Scottish fisheries managers to protect stocks
For decades governments and fisheries managers have made decisions regarding exploitation by the catching sector without the full knowledge of the state of
fish stocks and the marine environment. However, when it is obvious to all that many stocks are in serious danger, there is a total lack of action by Scottish
fisheries managers to protect stocks due to 'an insufficiency of data'.
To help overcome that 'insufficiency', the information gathered during Sharkatag will feed into SSACN's Scottish Shark Tagging Programme (SSTP - www.tagsharks.com ) which has been introduced to act as a central clearing point for all data regarding shark, skate and ray stocks in Scottish coastal waters.
Without regeneration, not only will Scotland's marine biodiversity lose more species, but the £150+ million/yr and the £25+ million/yr which sea angling contributes to the Scottish and Solway economies, will also suffer badly. With a little political will and some proactive measures, the biodiversity losses could be halted and the Solway could become a European centre of excellence for sea angling. This would probably bring another £15 million/yr to its economy through increased angling tourism.
