Using morphological criteria, we identified three types of blood cells in the freshwater prawn Macrobrachium rosenbergii. Hyaline hemocytes, the most abundant type, have few large cytoplasmic granules, a large nucleocytoplasmic ratio, and lyse spontaneously in the absence of anticoagulant. Granular

We developed a spermatophoremicroinjection (SMI) technique that allows exogenous DNA fragments to be transferred easily into the giant freshwater prawn (Macrobrachium rosenbergii), an important aquacultural shellfish and aquatic invertebrate model. From 28 to 1,000 ng of the circular plasmid pGL, in
Thermal stability of proteins in frozen and thawed freshwater prawns was measured by di β erential scanning calorimetry. The onset and peak melting temperatures corresponding to myosin denaturation, as well as total enthalpy of denaturation of prawn muscle, decreased after freezingΓthawing treatments
## Abstract A cDNA encoding vitellogenin (Vg) in the giant freshwater prawn, __Macrobrachium rosenbergii,__ was cloned based on the cDNA sequence of vitellin (Vn) fragments AβN and Bβ42 determined previously, and its amino acid sequence deduced. The open reading frame (ORF) encoded 2,537 amino acid
Four major yolk proteins, designated as vitellins (Vns) Macr-VnA, B, C, and D, were extracted from mature ovaries of Macrobrachium rosenbergii. These were purified to homogeneity by reversed-phase high performance liquid chromatography (HPLC) employing a unique separation system based on the hydroph
Daytime and nighttime rates of oxygen consumption N O z ) were determined for young freshwater prawns during progressive hypoxia. During daytime hypoxia VOZ fell slightly, then was maintained at 0,200 ml O,/gm/h to 40 mm Hg partial pressure of oxygen. Below 40 mm Hg VOz fell Dr. Spotts is now at Mia
