Czech scientist Zuzana Musilová from Charles University has attracted
international attention with the results of her research indicating that
three types of sea-fish have colour-vision in a deep sea environment.
Vertebrates were previously thought to have only monochrome vision in the dark. In an article published in Science magazine the scientist says the special genes that enable this were likely developer to assist species living in greater depth in the search of food and reproduction.
Veterinarians in East Bohemia have ordered some 80 tons of fish be
destroyed following an outbreak of the herpes virus at the Buñkov fish
farm near Pardubice.
Although the strain cannot be transmitted to humans, it is highly contagious among fish species. It is the first such outbreak reported this year.
The ceremonial launch of three days of harvesting began on Friday morning
at the largest Czech fish pond Rožmberk, near Třeboň in South Bohemia.
The town is the country’s most famous centre for the production of carp,
which is traditionally eaten by Czechs for Christmas dinner.
Overall, fishermen in Třeboň expect to harvest some 2,200 tonnes of fish from its 250 ponds this year. Last year, the traditional fish harvest attracted some 55,000 people.
Hundreds of dead fish have been found in the river Rokytná in Moravský
Krumlov in the Znojmo area in Moravia, a local official told the Czech News
Agency. According to a preliminary analysis the fish died due to a lack of
oxygen in a one-kilometre stretch of the river beneath the local chateau.
The recent hot and dry weather in the Czech Republic is posing a serious danger to aquatic species. Water levels in rivers around the country have fallen and the situation is particularly acute in minor rivers and streams.
Despite the annual Christmas carp sales, consumption of fish in the Czech
Republic keeps stagnating. According to the data of the Czech Statistical
Office, Czechs consumed 5.1kilos of fish per person last year, which was a
drop by 7.5 percent on the previous year and also the lowest figure since
Fish consumption in the Czech Republic remains to be one of the lowest in the European Union, where it amounts to around 11 kilograms per head. The amount recommended by the WHO is 17 kilograms of fish per head.
Czech scientists have discovered that a tapeworm found in Alaskan salmon can infect humans. The tapeworm had previously only been found in fish on the Asian Pacific coast. The discovery was made by a team from the Biological Centre of the Academy of Sciences based in České Budějovice led by Roman Kuchta. Infection can take place from eating under cooked or uncooked fish, such as in Sushi.
Czech fisheries are gearing up for the annual Christmas carp sales around the country, when sales of home-bred carp go through the roof due to the traditional Czech Christmas dinner of fried carp and potato salad. Although carp makes up for close to 90 percent of the fresh water fish bred in the Czech Republic many Czechs only ever eat it once a year- the rest is sold abroad.
Fishermen in Třeboň, south Moravia say they expect a harvest of around 2,300 tonnes of fish this year. The ceremonial launch of three days of harvesting began on Friday morning at the largest Czech fish pond Rožmberk, which is near Třeboň. The town is the country’s most famous centre for the production of carp, which is traditionally eaten by Czechs for Christmas dinner. This volume of fish expected this year is regarded as average.
