Fermentation based on Lactic acid bacteria (LAB) hold great promise for the management of a shrimp biowaste. Although shrimp biowaste is usually dried on beaches it encourages not only environmental pollution but also reduces the recoverable components. Experiments were carried out to test the Paediococcus bacteria for recovery of chitin and carotenoids. Paediococcus acidilactici ATCC 8042 was ...

This research report undertakes an interdisciplinary review of the concept of “control” (i.e. the idea that people should have greater “control” over their data), proposing an analysis of this concept in the field of law and computer science. Despite the omnipresence of the notion of control in the EU policy documents, scholarly literature and in the press, the very meaning of this concept rema...

In less intensive shrimp culture systems, polychaetes are known to be a major food item of several penaeid species. Under these conditions, very little is known about their population dynamics and the possible interactions with penaeid predation and artificial feeding. This work examined the effects of Penaeus subtilis, predation, stocking density and supplemental feeding on the population dyna...

BACKGROUND Little is known about the prevalence and clinical relevance of sensitization to shrimp allergens other than tropomyosin. OBJECTIVE We detected the prevalence of arginine kinase and sarcoplasmic calcium binding protein sensitization, and identified a high molecular weight allergen that is frequently recognized by Italian shrimp-allergic patients. METHODS Sera from 40 shrimp-allerg...

Crustacean hyperglycemic hormone (CHH) has many functions to regulate carbohydrate metabolism, ecdysis and reproduction including ion transport in crustaceans. The cDNA encoding CHH peptides containing 369 bp open reading frame encoding 122 amino acids was cloned from eyestalk of white shrimp (Litopenaeus vannamei) and was produced by a bacterial expression system. The biological activity of re...

Research on crustacean viruses is hampered by the lack of continuous cell lines susceptible to them. To overcome this problem, we previously challenged immortal mosquito and lepidopteran cell lines with shrimp yellow head virus (YHV), followed by serial, split-passage of whole cells, and showed that this produced cells that persistently expressed YHV antigens. To determine whether such insect c...

Protein is the major component for shrimp feeds and must be nutritionally appropriate and readily digestible. In vitro protein digestibility of feeds and feed ingredients, and their inhibitory effect on the digestive proteases of juvenile Farfantepenaeus paulensis were examined. The analysis included animal (four types of fish meal, meat meal and blood meal) and plant (soybean meal and wheat fl...

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...
