A clottable protein was purified from the hemolymph of tiger shrimp (Penaeus monodon) by sequential DEAE anion-exchange chromatography. The protein formed stable clots in the presence of Ca2+ and the transglutaminase in hemocyte lysate. It is thermostable at temperatures up to 66 degrees C. The molecular mass of the clottable protein was determined to be 380 kDa by SDS-PAGE and MALDI-TOF mass s...
The marine bacterium Vibrio parahaemolyticus, a known cause of gastroenteritis from seafoods, especially abroad,1011 also occurs in British coastal waters12-though only one incident traced to home-produced crabmeat has been reported.13 The vibrio is often present in imported crustacea, especially shrimps and prawns from the Far East, and these have been reponsible for some recent incidents.14 T...
This study investigated changes in landings of all prawns, white prawns (mainly Penaeus merguiensis), mangrove extent, rainfall and the area of shallow water in western peninsular Malaysia. The most important state for both the landings of all prawns and white prawns was Perak where about 50% of all prawns and 35% of white prawns were landed. This is also the state with the largest, and most st...

The juveniles of M. malcolmsonii were exposed to 24.1 microg l(-1) of Hg fora period of 21 days. The gills and hepatopancreas of test prawns were sampled and processed for electron microscopic observations. Mitochondria are the organelle most affected in the gills of test prawns. The number of mitochondria and the electron-density of the matrix were found to be less in test prawns. The in-foldi...
OBJECTIVE To determine whether viable White Spot Syndrome virus (WSSV) or Yellowhead virus (YHV) were present in prawn products imported into Australia. PROCEDURE A sample of fourteen uncooked prawns was obtained from a consignment imported from southeast Asia. Each of the prawns was examined for WSSV by polymerase chain reaction (PCR), and then a bioassay was conducted in which a 10% homogen...
Dams have long been associated with elevated burdens of human schistosomiasis, but how dams increase disease is not always clear, in part because dams have many ecological and socio-economic effects. A recent hypothesis argues that dams block reproduction of the migratory river prawns that eat the snail hosts of schistosomiasis. In the Senegal River Basin, there is evidence that prawn populatio...
A 95 days experiment was conducted to observe the growth performance of giant fresh water prawn (Macrobrachium rosenbergii) replacing fishmeal protein by dietary soybean meal in ten earthen mini ponds (50 m2), at Khulna University campus . Five experimental diets containing 25% as Control, Diet 1, 2, 3 and 4 were used. In 36% used a sole source prepared substituting with 30, 40, 50, 80% respect...
The total haemocyte count (THC), phenoloxidase activity, respiratory bursts (release of superoxide anions), superoxide dismutase (SOD) activity, and phagocytic activity and clearance efficiency to the pathogen Lactococcus garvieae were measured when freshwater giant prawns Macrobrachium rosenbergii (18.2+/-2.1 g) were individually reared in water containing concentrations of trichlorfon of 0, 0...
