Australia: Nursery confirms links to melon virus outbreak
Biosecurity Queensland has confirmed it's investigating a Queensland nursery linked to the outbreak of a virus that's crippled the Northern Territory's melon industry, but has refused to provide exact details about the nursery, or nurseries, involved.
Determining where cucumber green mottle mosaic virus (CGMMV) came from has been described as like finding 'a needle in a haystack'.
The virus originated overseas, and has devastated the Territory's horticulture industry since it was found on melon farms near Katherine in the Northern Territory seven weeks ago, and more recently on a pumpkin farm.
Ten farmers have had their properties quarantined and told to destroy their crops.
They've also had a two-year ban imposed on growing any crops related to the cucurbit family which includes cucumber and melons.
One theory is the virus was accidentally brought into Australia on infected cucurbit seed. From there, the seed is thought to have been grown out at a nursery before being sent to the Northern Territory.
New disease worries vannamei shrimp farmers
Wednesday, February 11, 2015, 02:40 (GMT + 9)
After achieving a record production of shrimp, which allowed the value of seafood exports from India to grow by 14 per cent yoy in the nine months ending December 2014, the industry fears that the disease known as RMS (Running Mortality Syndrome) may affect the production of vanamei shrimp in the new fiscal year.
The main affected states are Andhra Pradesh and Tamil Nadu, in the southern east coast, which are the major producers of this variety ofshrimp, and the top earners in the seafood export basket.
The Marine Products Export Development Authority (MPEDA) said it was early to assess the impact of the disease as farmers are seeding and filling the ponds, which will take some time.
Meanwhile, Anwar Hashim, managing director of Abad Exports, believes it is likely that the onset of the disease is due to the use of local broodstock, which is cheaper than the imported one.
What is RMS?

From European Commission website (http://ec.europa.eu/food/animal/diseases/african_swine_fever/index_en.htm):
African swine fever (ASF) is a devastating infectious disease of pigs, usually deadly. No vaccine exists to combat this virus. It does not affect humans nor does it affect other animal species other than pigs and wild boars. It can be transmitted either via direct animal contact or via dissemination of contaminated food (e.g. sausages or uncooked meat).
Lithuania made, in January 2014, the first notification of ASF cases in wild boar, and Poland followed in February 2014. In June and September 2014, Latvia and Estonia respectively also reported ASF. The disease is confined to the eastern part of these countries, along the border with Belarus and the Russian Federation. The disease is suspected to spread to the EU from the Russian Federation (RF) via Belarus.
The disease has been present in Russia since 2007, affecting wild boars and domestic pigs, and has spread in large part of the country. The EU was supporting the Russian efforts in fighting the disease by providing technical assistance in several occasions. The entry of the disease via the EU eastern border was expected. The recent cases of ASF confirmed the forecast made by EFSA on the entry of this animal disease in the EU. ASF spread widely in the RF and Belarus, posing a permanent important threat for the EU. Therefore the EU conducted an intensive prevention campaign, including the increase of awareness, strengthening of surveillance measures and more preventive measures put in place during 2013.
The EU is applying all the necessary measures to prevent the further spread of this virus into the EU. These preventive measures allowed for early detection of the virus on the eastern EU border. A demonstration of the EU capacity to control and contain this disease is its containment in Sardinia for decades without incidents on the continental part of the EU.
The EU is applying all the recommendations by the World Organisation for Animal Health (OIE) and is constantly in open dialogue with its trading partners bilaterally and via the World Trade Organization (WTO).

China's output from aquaculture is the largest in the world and accounts for about 67% of the world's total production.
Expansion in aquaculture is happening at an intense rate, while demand for seafood pushes China toward more import than export.
The number of environmental problems reported in aquaculture is alarming.
In the coming year IBIS will collect information and do analysis on where China may be in 10 years time - opporunities and the road to success.

Source: Quarterly Aquatic Animal Disease Report (Asia-Pacific Region) – 2014/3One of the important issues discussed was thecurrent emerging disease threats for shrimps including infection with Enterocytozoon hepatopenaei (EHP; microsporidian) and Covert mortality nodavirus (CMNV). It was suggested that these two diseases be included in the QAAD list but decided that a Disease Advisory be released instead. This will be done as an awareness programme activity and to gather data from other countries if these two diseases are present or not. Disease advisories will be prepared by NACA with assistance from Dr. Flegel (for EHP) and Dr. Huang (for CMNV).
Excerpt from Reports:
NEW ZEALAND - New Zealand King Salmon wants to know why an unusually high number of fish died at one of its Marlborough Sounds marine farms last week.
...fish with small lesions like swollen mosquito bites...
...Ministry of Agriculture and Forestry was looking for a wide screen of viruses, including ISA.
NZ King Salmon CEO Grant Rosewarne says company vets believe the farm was the subject of some extraordinary natural event or combination of factors.
There are no environmental problems at the farm and testing has ruled out the presence of any known disease-producing agents, Mr Rosewarne says.
Our experts believe the farm may have suffered from an extraordinary event that directly killed the fish by interfering with them physiologically. Whatever it was, it also put other fish off their feed.
The Ministry of Primary Industries confirms on its website that it is not always possible to determine a cause for a mortality event.
It says its Waihinau investigations focused on ensuring that the event was not caused by infectious agents. The investigation has ruled out a number of exotic and endemic disease threats. No cause for the excess mortality has been identified.
UPDATE 14 Oct 2013
Excerpt from NZ-MPI Report July 2013
Testing performed at AHL ruled out a number of enzootic and exotic pathogens.
Further investigation to identify the cause of this annual mortality increase, and whether it is related to the external ulcers, heart pathology and suspected intracellular parasites is recommended in the future.
