Branchiopod crustaceans are represented by fairy, tadpole, and clam shrimps (Anostraca, Notostraca, Laevicaudata, Spinicaudata), which typically inhabit temporary freshwater bodies, and water fleas (Cladoceromorpha), which live in all kinds of freshwater and occasionally marine environments [1, 2]. The earliest branchiopods occur in the Cambrian, where they are represented by complete body foss...

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...

The effect of formalin on the organoleptic parameters, biochemical composition and storage quality of iced and frozen stored giant freshwater prawns (Macrobrachium rosenbergii) was investigated. The organoleptic characters such as appearance, textural condition, colour, odour of both formalin added and non-added prawns were evaluated. The quality of non-added prawns was judged good up to first ...

Freshwater decapod crustaceans are important components of food webs in these environments, but little is known about the diet of species that live in tropical waters. We studied the feeding ecology of the prawn Pseudopalaemon bouvieri and its population structure in two different areas with six lagoons, with a different composition and abundance of aquatic macrophytes. At each site of macrophy...

An epizootic bacterial infection in the giant freshwater prawn Macrobranchium rosenbergii occurred in Taiwan from May to June 1999. The cumulative mortality was approximately 30 to 75%. The diseased prawns showed opaque and whitish muscles and were approximately 2 mo old with total lengths from 5 to 6 cm. Histopathologically, they showed marked edema and necrotic lesions with inflammation in th...

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...

Macrobrachium tenellum and M. americanum are common freshwater prawns from the Americas' tropical subtropical Pacific continental side. They have different biological attributes currently threatened by human impact on their ecosystems. Both species provide quality products for consumption intensively exploited without proper management. This study analyzes, discusses, compares available informa...
