Demon Shrimp discovery means ballast convention must be ratified
31.10.12
Angling Trust claims further delay on invasive non native species would
be 'negligent'
The news that the Demon shrimp (Dikerogammarus
haemobaphus) has been discovered in the River Severn and is almost
certain to spread to other river systems could be devastating for anglers and
extremely damaging for our fisheries. The
Angling Trust is demanding that the government immediately announce the
ratification of the International Maritime Organisation’s International
Convention for the Control and Management of Ships' Ballast Water and
Sediments. Ballast water transfer has been identified as a major pathway for
invasive species to spread across the globe, threatening ecosystems as they are
moved. This Convention has been ratified by countries as far away as Antigua
but not by the UK. The Trust has today written to the Parliamentary
Under-Secretary for Transport, Stephen Hammond MP, pointing out that further
delay would be ‘negligent’.
The Demon Shrimp, like the Killer Shrimp which found its way
into a number of still waters last year, is a non-native species and is
predatory on other insect life. It could
therefore dramatically affect the availability of the main food source for most
species of fish and many birds, with unknown but potentially disastrous
consequences.
Angling Trust chief executive Mark Lloyd said:
“This news is similar to the recent discovery of a killer
fungus that could decimate ash trees in our woodlands. Put alongside the
existing problems of signal crayfish and the recently arrived Killer Shrimp, it
is vital that the government takes all appropriate steps to reduce threats from
invasive non native species to our environment. As an island we have an advantage over other
countries and we should make the most of that by cutting
off the known routes by which these species can invade. An obvious one would be immediately to ratify
commonsense and long overdue measures to prevent their transfer through ships’
ballast. We call on DEFRA to work up an
integrated strategy to tighten up on controls on imports, and to increase
public awareness and education about bio-security measures needed to stop these
species from spreading further in the UK.”
