The
programme is designed to tag the majority of the shark species found
within UK coastal waters
The
UK SHARK TAGGING PROGRAMME was the
first 'Angler Driven' Programme of its type in the U.K. The programme
aims at all our larger species of shark, from Common Smooth Hound
(Mustelus mustelus) and Starry Smooth Hound (Mustelus
asterias) to Blue Sharks (Prionace glauca)
Porbeagle Sharks (Lamna nasus) and Mako Sharks (Isurus
oxyrinchus ). In fact the programme looks to address 8 primary
species of shark that have rarely been studied in any depth, with the
tagging programme providing the 'Foundation of Data'. With all bar one
of the species being live-bearers, and thus especially vulnerable to
over-exploitation.
The programme was a long time in arriving in the U.K. - 10 years or
more! Having seen first hand the benefits of programmes in Ireland, read
of the works on the NMFS along the east coast of America with their Apex
Predator Programme; "why haven't we got a tagging scheme in the U.K.?" -
became the obvious question! The Irish programme organised by the
Central Fisheries Board, was aimed at reviewing the socio-economic
benefits of sharks in their waters with regard to tourist anglers. The
American programme studies sharks as part of an ongoing management of a
valuable resource both to commercial and recreational factors.
Both these programmes are tagging sharks to monitor life cycles of their
fish in local and distant waters - so that through greater understanding
of the fish they can develop the best fisheries management policies.
Without the detailed knowledge of various shark species, very little
would be done to conserve their populations, in healthy numbers. Here is
where tagging comes in, it is the only non-destructive
study method available. With recreational sea anglers playing a major
role in the whole operation 74% of all the 6000+ Blue Sharks tagged in
the NMFS Apex Predator Programme in the last 20+ years have been by
anglers. No agency, government or otherwise can afford to pay
scientists/marine biologists to effectively tag and release that number
of fish! Anglers do it for free, and out of their love for the fish and
for the sporting nature of their fish
Sue and Jeri Drake started attending conservation workshops aimed at
sharks in 1990 and it soon became apparent that, unless anglers took the
initiative and developed a programme themselves it would never happen.
Discussions over the years ranged from threats to sharks in various
oceans, possible breeding ground of Great Whites in the Med, tourist
diving with Whale Sharks, but never the real problems of sharks in our
own waters,. As a non-quota food fish species they were of little
interest to MAFF (now DEFRA), who had higher priorities on their limited
budget, and anyway sharks are not a major food fish when compared with
Cod or Plaice
So, it has been left to the anglers! Sue and Jeri Drake developed an
outline proposal for a Nationwide UK Shark Tagging Programme as far back
as 1991, and have basically been seeking funding for it ever since. 1998
saw one of those rare moment of opportunity come along;
with the motive and means being all in the
right place at the right time! So the deed was done! The 1999
Preliminary Shark Tagging Programme (Tope) was born. This project was
designed as a 'stepping-stone' to the full scale Nationwide Programme.
Funded by WWF (World Wide Fund for Nature) it aimed to assess whether
recreational sea anglers could tag sharks in U.K. waters - mainly Tope.
Focussed around the Isle of Wight and the sports fishery operated by the
Langstone Harbour Professional Boatmans Association to the east of the
island. The project certainly proved a success - UK sea anglers could
tag sharks!
During 1999,
through the interest generated by the Preliminary Project, Sue and Jeri
Drake refined the earlier proposal to accommodate a system of 'catalyst
style' funding from WWF. For the first year the balance of funding was
donated by Angling Trade Association (ATA) with supplementary
contributions by EFSA (Executive), EFSA (UK) and South West Federation
of Sea Anglers (SWFSA). The funding from WWF over three years (2000,
2001 and 2002) was on a declining basis.
SHORT
AND LONG TERM DEVELOPMENTS
Tagging of sharks will provide a number of benefits to the whole of
the recreational sea angling community, through demonstration of
anglers conservation efforts to greater input in development of
fisheries management. While the programme is being administered by Sue
and Jeri Drake, data from the tagging programme will provide the raw
data for scientific studies and analytical assessments
Some of the developments will come in the form of greater knowledge
thus giving sea anglers a greater/ better understanding of the habits
of their sporting species of sharks. Short and long term migrations,
population dynamics and stock composition, all aspects that we are
currently only going on anecdotal reports. Information loosely
gathered from numerous and possibly 'inaccurate' sources. The tagging
programme, through accurate data recording (by the taggers) will
provide the evidence to dispell some of the folk-lore surrounding our
larger shark species.
From our own observations we have dispelled some of the myths, but
only for our own personal consumption; like "Blues only feed once a
day!". Well we have records that show Blue Sharks feeding more than
three times, and on all those occasions there were hooks attached to
the baits, the same tagged fish kept on returning. It is like one of
the small results that came out of the 1999 Tope Tagging Project;
before we started, the skippers all said that they caught all their
Tope over the 'spring tides' and at slack water. When in fact, they
caught them evenly over all tides and at all states of the tide; it
was only by analysing the return cards that we found that there were
no real tidal of time corralations on their catches.
Back to the UK Shark Tagging programme, the programme will be free to
enter, subject to available funding, and available to all disciplines
of sea angler, be they shore, small boat, club or charter anglers.
Though the programme will aim to provide the greatest coverage through
charter boats and clubs, as this will give the best concentrated use
of the limited number of tags available each year. The notional
boundaries set down are that the programme will cover all of England,
Wales, Scotland and various islands
The Programme will accumulate the record card data on a single
computer (that is NOT linked to the internet), and this data
will NOT be distributed to any group or body with any
commercial fishing interests. The data will never be used to discredit
recreational sea angling, nor will it be distributed freely around the
'marine biology' community. The control of data will be closely
guarded, and only available in its 'raw and total' format to a limited
number of 'vetted' biologists. A lot of effort you might ask, but we
wish to alay any fears amongst potential taggers, that the data might
be used against sea angling. This was a fear/worry raised by a number
of charter skippers when we ran the 1999 Tope Tagging Project, as they
did not wish to contribute to a project that might ultimately damage
their 'Tope Fishery'. Continued monitoring of catch/tag returns will
be carried out each year, with an annual report being 'published';
with copies going to all 'registered taggers' and abridged copies to
the sea angling press for onward publication. Further studies will be
carried out from time to time on the whole database by selected
'marine biologists', who will be working directly for the tagging
programme, their reports will also be made available to the taggers.
Lastly, when a 'tagged shark' is recaptured, the original 'tagger'
will be notified that his/her fish has been recaptured, along with any
quickly derived data, like days at liberty, distance travelled,
weight/length gain, etc; this we feel is an intrinsic part of the
Programme to full involve the 'tagger' with their shark.
