With their pretty villages and miles of waterways, the Norfolk Broads attract a million tourists each year, but there are fears the smell of dead fish could be getting up visitors' noses.

While recent temperatures topping 20C (68F) have attracted the first holidaymakers of the season to the area, the pleasant weather could have the unfortunate side effect of increasing a build up of toxic algai which depletes oxygen levels in the water and kills fish.

Environment Agency (EA) workers have recently been forced to relocate more than half a million fish and are carrying out daily monitoring after anglers spotted carcasses floating in some waterways, including Hickling Broad near Potter Heigham. WORDS: PA.

If the forecast warm weather continues, this could increase the bloom, meaning the figure could reach more than one million, a spokesman said.

Anglers have warned the rising numbers of dead perch and bream could put off visitors to the National Park - previously re-branded as Britain's Magical Waterland - and have a knock-on effect on biodiversity.

Bosses at the Broads Authority, which manages the area, have said they are working hard with the EA to find a solution - adding that the problem should not put off visitors as it was confined to small areas.

Kelvin Allen, eastern region chairman of the Angling Trust, said the algai had been a problem for several years but it had been particularly prevalent this year.

He said: "Our members first noticed fish behaving strangely around Christmas - they were moving from their normal locations and weren't interested in food.

"Obviously, this is of concern to anglers but it also has further reaching implications.

"If you take into account the birds which feed on the fish and the wider food chain, this could have serious consequences to the natural environment."

The algai bloom has been attributed to a mixture of environmental conditions, including salinity and water temperature.

It is not known what has caused these conditions to alter so dramatically, but Mr Allen said dredging and land drainage could be factors.

He said there needed to be a coordinated response to bring together groups such as anglers, farmers and tourism businesses to find a solution.

"The Broads are the UK's largest inland fishery and 18% of visitors take part in angling at some point during their visit," he added.

"People come here to enjoy nature and the outdoors.

"If we don't protect the natural environment, we could lose the very thing that makes it special.

"Apart from anything else, as temperatures start to rise in summer, the smell of dead fish could become quite unpleasant."

A Broad Authority spokesman said: "Huge numbers of visitors are enjoying the Broads during the current spell of great weather and will continue to throughout the season and beyond.

"The fish issue is confined to a tiny part of the waters and once whatever water conditions are causing it have resolved, numbers will naturally recover."

The EA rescued and relocated 230,000 fish last month after they were found shoaling in a shallow haven away from the bloom near Potter Heigham.

A further 110,000 have recently been moved from Somerton, roughly six miles away, and over the weekend another 300,000 fish were moved.

Once transported a sufficient distance from the bloom, the fish are able to swim freely into surrounding rivers.

The last similar occurrence in Hickling Broad was in 2012 when 35,000 fish were rescued and relocated.

An EA spokesman said: "Our teams have taken action to rescue and relocate more than half a million fish in the Norfolk Broads which were in danger of suffocating due to the effects of a Prymnesium algai bloom.

"We are continuing to work around the clock to monitor the situation. "

Dan Hoare, from the Broads Authority, said it was working with specialist laboratories in France and the UK to develop better testing techniques to find the best approach to tackling the issue.

He added: "We understand the public concern and the impact this is having and are doing everything we can to support and facilitate the Environment Agency, as the organisation responsible for fish welfare and events which affect it, in monitoring and resolving the situation."

Anyone who sees dead or distressed fish should contact the EA hotline on 0800 807060.

Dead fish are causing a stink on the Norfolk Broads
Beautiful Hawaii boasts world-class surfing, spectacular waterfalls and active volcanoes, as well as a hot climate. Temperatures at sea level generally range from highs of 29 to 32C during the summer months to 26 to 28C during the winter months. Rarely does the temperature rise above 32C or drop below 18C. To see snow in winter, you will have to head for the islands' highest mountains.
You won’t get snow in Puerto Rico. Only palm trees, white sand, sunshine and year-round temperatures of 24 to 31C. The tropical climate can get humid in the summer months and Puerto Rico experiences the Atlantic hurricane season (June to November) with a hurricane passing the vicinity of the island on average every 11 years. Only one Category 5 hurricane has struck the island since 1851, the Lake Okeechobee Hurricane of September 1928.

Like the rest of the Caribbean, the tiny island of Saint Lucia boasts a warm, tropical climate all year round. Trade winds stop things becoming too hot with temperatures ranging from 21 to 32C. The wet season is generally at the same time as the Atlantic hurricane season (June to November). The most humid weather can be found in the rainforest in the centre of the island, while a hike to the Pitons will help you cool off. 

Sitting on the eastern coast of Central America, Belize enjoys a comfortable tropical climate with an average yearly temperature of 29C with only about 4C between the coolest (January) and warmest (May) part of the year. The coastal breezes help ease high humidity levels. With consistent temperatures all year round, Belize only has two seasons, the wet (from June to December) and the dry (February to May).

Separating the Caribbean Sea from the Gulf of Mexico, the Yucatan Peninsula enjoys warm weather all year round at a steady 27C and seasonal fluctuations of just 4 to 6C either side. It does lie within the Atlantic Hurricane Belt and with almost uniformly flat terrain is vulnerable to large storms coming from the east.

Lying just to the south of the Equator, this archipelago of 115 islands in the Indian Ocean stays warm and humid throughout the year with temperatures rarely dropping beneath 24C or rising above 32C. The seasons are controlled by trade winds and the Seychelles does not experience extreme weather conditions.

Durban, the largest city in KwaZulu Natal, boasts an average of 320 days of sunshine a year. Temperatures range from 16 to 25C in winter and from 23 to 33C in summer, with January the hottest and most humid month. The warm Mozambique current flowing along the coast means the water temperature rarely falls below 17C even in winter. The city is occasionally affected by tropical storms during the cyclone season (November to April).

These picturesque islands in the heart of the Great Barrier Reef enjoy a subtropical climate with an average annual temperature of 27C and lots of sunshine. Summer in January sees an average temperature of over 30C in Australia's Whitsunday Islands, with the water temperature not far off.

You’ll never see snow on the tropical island nation of Fiji in the South Pacific. Maximum temperatures rarely move out of the 26 to 31C range all year round. Southeast trade winds from March to November bring dry weather and the rainy season runs from December to April, which overlaps with the tropical cyclone season.

The temperature hardly ever changes in the Maldives, averaging a warm and humid 30C throughout the year. That’s thanks to their equatorial location, which also keeps them out of the firing line of cyclones. The tropical equatorial climate has two seasons, with the highest temperatures occurring during the dry season (November to March).
