A Reo-like virus associated with high mortality rates in cultured mud crab, Scylla serrata, in East China

چکیده
The discovery of a reo-like virus in cultures of the mud crab Scylla serrata (Forsskål, 1755) is reported here. Since May 2004, in Zhejiang Province, Peoples Republic of China, reo-like virus in mud crabs has reached serious epidemic levels, causing mortality rates exceeding 90%. Beginning in May 2004, moribund crabs from different districts and areas were investigated. By using electron microscopy, two different organisms could be detected: reolike viruses and mollicute-like organisms. The complete viral particle is 60 nm in diameter, icosahedral and non-enveloped. The viruses infect the cytoplasm of connective tissue cells of the gill, stomach, heart and intestine of mud crabs.

The Sampling one-year period from October 92 to October 93 on a monthly basis was conducted using gillnets and baited traps. 70% of gillnet catches during flood tide consisted of adults. Sub-adults and juveniles were 28 % and 4.5%, respectively. Similarly, during ebb tide consisted of 51.7%, 24.2%, and 24.1%, respectively. It suggests that gillnets are not sized selective gear. In contrast, bai...

Introduction of non-indigenous species into a well-established ecosystem can be detrimental, resulting in both ecological and economical damage. Two specimens of giant mud crab, Scylla serrata were found for the first time in two geographically distinct mud crab landing sites (Matang Mangrove Forest Reserve, Perak and Kota Marudu Mangrove Forest, Sabah) in Malaysia. Their identities were confir...

For the first time, a mollicute-like organism (MLO) was cultured from moribund mud crabs (Scylla serrata) during an outbreak of clearwater disease in Zhejiang Province, China. The MLO displayed a fried-egg colony morphology in culture, did not possess a cell wall, and was not retained by 0.45 μm and 0.2 μm filters. It was able to ferment glucose, sucrose, lactose, and maltose, but it did not ut...

Selective tidal-streaming is a model frequently used to explain how planktonic larvae invade estuaries. The ability of larvae to move vertically in the water column to selectively ride favourable currents and maintain ground gained is critical to this process. The mud crab (Scylla serrata) is a widely distributed, commercially and recreationally important portunid crab but little is known about...
