The effects of substitution of seaweed, Sargassum ilicifolium, by replacing protein resources, in Litopenaeus vannameii diets was studied. It was carried out by incorporation of raw powdered seaweed at three levels, 0% as control treatment, 5% (C), 10% (B) and 15%(A)  each with four replications in isoprotein, (33%) and isocaloric (355kcal.100-1) diets.. Binder properties of seaweeds in differe...

Quality production of the shrimp Penaeus monodon in hatchery operations depends heavily on the evaluation of genetic diversity and population structure of brood stocks. Mitochondrial DNA (mtDNA) sequences have been widely used to study genetic variability and relationships in many crustacean groups, and these same markers may be incorporated into evaluation studies of shrimp broods and populati...

the present work was carried out to study the effect of vacuum packaging and pomegranate peel extract (pe) treatments on the quality of pacific white shrimp (peneous vannamei) during refrigerated storage. changes in ph, thiobarbituric acid (tba), total volatile base nitrogen (tvb-n), trimethylamine (tma), aerobic plate counts, psychrophilic, lactic acid bacteria and enterobacteriaceae counts, m...

Although the JAK/STAT signaling pathway is usually involved in antiviral defense, a recent study suggested that STAT might be annexed by WSSV (white spot syndrome virus) to enhance the expression of a viral immediate early gene in infected shrimps. In the present study, we clone and report the first full-length cDNA sequence for a crustacean STAT from Penaeus monodon. Alignment and comparison w...

At least four virus caused pandemics have adversely affected the global penaeid shrimp farming industry since 1980. These viruses in the approximate order of their discovery are Infectious hypodermal and hematopoietic necrosis virus (IHHNV), Yellow Head Virus (YHV), Taura Syndrome Virus (TSV), and White Spot Syndrome Virus (WSSV). The socioeconomic impact of the diseases caused by these viruses...

Reproductive patterns and populations characteristics of 5 deep-water pandalid shrimp species of the genus Plesionika (Decapoda: Caridea) were studied between 150 and 1100 m depth in the Western Mediterranean Sea over the period 1991 to 1994, including monthly samples taken from November 1992 to October 1993. With the aim of establishing interspecific relationships among reproductive biology an...

Macrobrachium ohione is a migratory (amphidromous) river shrimp (Decapoda, Caridea) that may be parasitized by the branchial parasite Probopyrus pandalicola (Isopoda, Bopyridae). The parasite disrupts gonadal maturation and spawning in female shrimps, resulting in the total loss of reproduction. Shrimps are usually infected by bopyrid parasites during the late zoeal or early postlarval stages; ...

Within the past decade, viral diseases have emerged as serious economic impediments to successful shrimp farming in many of the shrimp-farming countries of the world. In the western hemisphere, the viral agents of Taura syndrome (TS) and infectious hypodermal and haematopoietic necrosis have caused serious disease epizootics throughout the shrimp-growing regions of the Americas and Hawaii, whil...
