Next time you buy fish at the supermarket, it may not be what it appears to be - according to the authors of a new paper on truth in food labelling in the European seafood industry.

Mother Jones reports that researchers from the School of Biology and Environmental Science at UCD found a surprising 25 per cent of haddock and cod products "randomly sampled from supermarkets, fishmongers' shops and take-away restaurants" in Dublin "were genetically identified as entirely different species from that indicated on the product labels".

The team also stated that 28 out of 34 selected samples of smoked fish were found to be labelled incorrectly.

"These results indicate that the strict EU policies currently in place to regulate seafood labelling have not been adequately iimplemented and enforced," they said.

The paper - Smoke, mirrors, and mislabeled cod: poor transparency in the European seafood industry, by Dana D Miller and Stefano Mariani - is published in the current issue of the journal Frontiers in Ecology and the Environment.

The European Parliament and European Council have formally adopted a regulation giving new compensation rights to passengers using water transport. The regulation is expected to come into force at the end of 2012.

"People are entitled to enjoy the same levels of quality and safety wherever they travel within the European Union. I am very glad that after introducing rights for air and rail passengers, we are now also able to introduce similar rights for passengers travelling by water" said Siim Kallas, Commission Vice President and responsible for transport.

The new regulation that will enable passengers travelling by sea and by inland waterways to enjoy the same rights wherever they travel in the European Union. The information can be viewed in full from the Irish Maritime Development Office (IMDO) website: www.imdo.ie
