Poisonous mussels?



In Asia, the cultivation of carp in freshwater has been going on for about 4000 years. In Europe the cultivation of fish and mussels goes as far back as the Roman Empire, 2000 years ago. Fish cultivation in freshwater has dominated, probably because of the large rom and larvae are easier to cultivate than saltwater specie with their small rom and larvae. In the nordic countries, fish cultivation has been practised since the 17th centuary. Since the beginning of the 20th centuary, cultivation has also been practised in saltwater. In the beginning, extensive cultivation dominated and the effects of releasing fry into the water was hardly noticable. After the second world war, the techique of large scale cultivation started to spread outside Asia. The reason for this development had several reasons, amongst them, the inability of the fishing industry to increase catches because of overfishing, the introduction of fishing zones and the increase in global populations. Since the 1960´s, fish cultivation has expanded greatly and cultivation in neted enclosures dominates amongst the industrialized nations.
    Even the cultivation of molluscs, i.e. blue mussel and oyster, has its origins in Asia. Blue mussel shells have been found at a 5000 year old settlement at Rottjärnslid in the west of Sweden, but it is not known if the mussels were used for food or as bait. Swedish experiments in the cultivation of blue mussels started in 1970.
