The osmoregulatory ability and salinity tolerance of four species of decapod crustaceans (Decapoda: Natantia) were evaluated to test the degree of physiological adaptation to variations in salinity (2 d exposure to 10, 20, 25 and 32. The ecophysiological salinity tolerance of two penaeids (Metapenaeus joyneri and Penaeus semisulcatus) and two palaemonid species (Palaemon pacificus and Exopalaem...

Serotonin (5-HT) mediates a number of diverse physiological functions in crustaceans by interacting with various 5-HT receptor subtypes. A putative 5-HT receptor cloned from the ovary of the black tiger prawn (Penaeus monodon) consisted of 2291 nucleotides, encoding a putative 5-HT(1Pem) receptor protein of 591 amino acids. Transient expression of 5-HT(1Pem) in HEK293 cells demonstrated a satur...

A study was carried out to evaluate polymerase chain reaction (PCR) for the detection of white spot syndrome virus (WSSV) in postlarvae and broodstock of Penaeus monodon and in potential crustacean carriers from India. Primer pairs designed for WSSV affecting Penaeus japonicus (WSSV PJ) and P. monodon (WSSV PM) were used. Both the primer pairs gave positive assay results for crustaceans showing...

Li X.Y., Li Z.-X., Lin H., Samee H. (2011): Effect of power ultrasound on the immunoactivity and texture changes of shrimp (Penaeus vannamei). Czech J. Food Sci., 29: 508–514. The aim of this study was to examine the effect of power ultrasound on the allergenicity and texture properties of shrimp (Penaeus vannamei). For this purpose, raw and boiled shrimps were treated with power ultrasound (30...

Upaya untuk meningkatkan pemanfaatan protein dalam pakan dapat dilakukan dengan penambahan bakteri proteolitik. Penelitian ini bertujuan skrining proteolitik pada saluran pencernaan udang Jerbung (Penaeus merguiensis) sebagai kandidat probotik. Skrining mengisolasi dari yang diperoleh tangkapan nelayan di pesisir pantai Pasuruan, Jawa Timur. Dari hasil isolasi lebih 30 koloni tumbuh media, sela...

The giant or black tiger shrimp, Penaeus monodon, was formerly the dominant cultured shrimp species in Asia. Since approximately 2002, it has been essentially replaced by the domesticated American whiteleg shrimp P. vannamei. The change in dominant species has affected disease concerns. For both species, white spot syndrome virus (WSSV) and yellow head virus (YHV) are the most lethal. For P. mo...
