On 8th September 2016 – whilst much of the marine industry was enjoying German hospitality at SMM in Hamburg, Finland was busy depositing its ratification of the ballast water management (BWM) convention with the IMO in London, bringing a convention 12 years in the making over the line.
Five years have passed since the magnitude 9 earthquake struck Japan, unleashing a savage 133-foot high tsunami which claimed the lives of 16,000 people. Upon its retreat, the giant surge of water carried an estimated 5 million tons of debris out to sea – including Japanese docks, ships and household items, which are still arriving along the Pacific coast of the US and Canada five years later.
This jellyfish-like creature originates from the Atlantic coastal waters of North and South America. However, in 1982 it was spotted in the Black Sea, and it subsequently spread to the Caspian Sea, the North Sea and the Mediterranean Sea.
Peru has finally acceded to the IMO Ballast Water Convention, making them the 51st state to do so. Their accession coincided with the IMO’s end of May global tonnage figures, which also indicated a slight increase in the ratification percentage from the end of April figures.
This weeks invader is the Fishhook Water flea.
With the number of ballast water treatment systems on the market ever on the increase, one would think that it would be fairly straightforward to find one that is suitable. Sadly though, choosing the right BWTS for a vessel is a task that couldn’t be further from ‘straightforward.’ The list of factors to weigh up before making a decision is enough to leave even the most experienced in the industry with a headache. We hope that you find this short list of do’s and don’ts helpful. Don’t: 1. Pick a system based on price alone. The price may make some …
And the new winner of Invader of the Week is… Eriocheir Sinensis, aka The Chinese Mitten Crab!
Native to the Yellow Sea region of China and Korea, they were first found in Germany in 1912. Before long, droves of this eight-legged army had spread to Denmark, Poland, Belgium, Sweden, the UK and Ireland. By the 1960’s they we’re found to have traveled as far as the Great Lakes.
This week’s invader of the week is the Quagga Mussel
The Quagga Mussel (Dreissena Rostriformis Bugensis) is a species of mussel native to the Black and Caspian seas, thought to have been transported to Western Europe and North America through ships’ ballast water. Whilst not posing a direct predatory threat to local species, the Quagga Mussel does significantly disrupt the local aquatic lifecylce due to its prodigious filtering of the local water of important phytoplankton and suspended particulates, with each mussel capable of filtering up to one litre of water per day. The Quagga Mussel’s tenacious breeding abilities make it a significant economic threat to industrial and civil areas.
This week’s invader of the week is the Killer Shrimp.
The Killer Shrimp (Dikerogammarus Villosus) is actually an amphipod, rather than a shrimp, but earns its reputation from its aggressive and vicious behaviour. Native to the Black and Caspian seas, it is thought to have been transported to Western Europe and, most recently, the United Kingdom via the ballast water and hulls of ships.
Much of the marine industry is focused on the commercial issues with regards to ballast water treatment. To raise the awareness of the ecologic issue of invasive species, BWC will be now be posting an “Invader of the Week” blog post each week. This week it is the delightful Asian Shore Crab…
