KHV Outbreak Worsens in UK
More than 200 stillwater fisheries in the UK have been stocked by fish suppliers believed to be possible sources of the UK's current Koi Herpes Virus outbreak it is believed. A letter from the Environment Agency received by the Angling Times, states that there have been 12 confirmed cases of KHV in stillwater fisheries in England so far this year: ten of the fisheries have been legally stocked this year with carp from 26 different suppliers, but the remaining two have not been legally stocked this year; suggesting that either KHV was already present in the fish, or that it was introduced on illegally stocked fish.

Gill Adaptation to Oxygen Shortage
University of Oslo scientists have discovered how the Crucian Carp is able to live for months without oxygen. They have found that it can change the structure of its gills to avoid becoming anoxic. Its blood also has a much higher affinity for oxygen than any other vertebrate, and it also makes tranquillisers and produces alcohol when oxygen supplies are limited.
Most animals can only last for a few minutes without oxygen, but the Crucian Carp can survive for several days with almost no oxygen. The ability to live in these conditions allows the carp to survive the winter in the shallow ice-covered ponds of Scandinavia. Researchers still do not understand fully how these fish do this, but they know that their heart rate is a major contributing factor.
The fish survive by drastically slowing down their heart and other systems inside their bodies. They then produce few waste products, such as lactic acid, which can harm the body. The fish convert the lactic acid to ethanol, which is much less harmful. Ethanol is a form of alcohol, and so the fish does eventually need to remove it from its system. It is thought that the ethanol is circulated to the gills of the fishes, where it can flow out and into the water.
Indonesian Fish Imports to Pass Through Malta
In order to facilitate the overseas marketing of its products, Indonesia has named Malta as one of the entry gates for the country’s fishery products to the European Union. Marine Resources and Fisheries Minister Freddy Numberi said that access for Indonesian fishery exports (including ornamental fish) to Europe would be easier through Malta due to its location near the southern borders. "The transportation cost from Indonesia to Malta will also be lower than from Indonesia to other countries or cities in Europe," said Numberi. "Malta's position between Europe and Africa could also be used as an entry gate to the Middle East or African countries."

Abattoir Waste-water Fish Project to Expand
The first effort at culturing fish in an abattoir’s waste-water has been successfully completed in a trial in South Australia. Tatiara Meat Company, a lamb exporter, consumes about 1 million litres of water in an average day in its operations. Most of the water used is then recycled, however, waste water held in storage ponds is now being used to grow ornamental goldfish and carp, which purifies the water making it suitable to irrigate pasture for fodder for livestock. Environmental officer Fil Farina says the project is likely to expand. "A lot of meat processing works do have storage lagoons on site and also a lot of them do have further processing facilities. I do see a big future for this sort of a project".
Aqua-One, the "science-first" bacterial product known for outstanding results is now even better, according to the manufacturer. With more strains of beneficial bacteria, Aqua-One is works for seeding bio-filters, controlling nutrient in the spring and summer and for reducing sludge all year.

A New Scented Waterside Bamboo for the Koi Pond
Phyllostachys atrovaginata ‘Green Perfume’ is a new winter-hardy waterside bamboo, which is shortly to be introduced to gardeners by Dutch bamboo specialist Jan Oprins. Originating from China, it is a straight, upright-growing plant, which reaches a height of 5-8m (16-26ft). The shoots are edible. When the young stalks are rubbed the scent of incense is released. It enjoys damp conditions and flourishes in wet soils at the water’s edge and is a perfect complement to the larger koi pond.

This is a range of products for the koi-keeper that will aid in their battle against the devastating ulcer disease. The Aqua Probiotics System works on the principle of competitive exclusion by introducing harmless, but stronger competitive organisms into the water, which compete directly with the bacteria that create the problem.
White Spot Disease Strains Identified
Scientists from the United States have become the first to provide experimental evidence to show the difference in virulence amongst the various different strains of the White Spot parasite, Ichthyophthirius multifiliis. A team of parasitologists from the Department of Infectious Diseases at the University of Georgia’s College of Veterinary Medicine studied two forms of the White Spot parasite, and found that one of them killed all of the fish infected while the other only killed half.
The parasite strains studied, differed in the presence of a particular type of membrane protein found on their surface called an immobilisation antigen or i-antigen. So far five different types of White Spot have been described and can be identified from their characteristic i-antigens. The function of i-antigen proteins is not known, however, when they are purified and injected into fish they give the fish immunity against White Spot parasites expressing that i-antigen protein in their membranes.
