Semi-intensive prawn farming is currently facing difficulties in both the production and consumption processes. Climate change an unstable output market are main causes affecting investment efficiency of semi-intensive farming. The authors carry out study to evaluate financial My Xuyen District, Soc Trang Province. Research data collected from 100 households raising prawns. research results sho...

Background Nowadays in countries all over Europe more and more people consume shrimps and other types of sea food. Consumption of even one or two shrimps can induce anaphylactic reaction in patient with allergy. In this work our aim is to present a case of patient admitted to the Department and Clinic of Allergy, Clinical Immunology and Internal Diseases to diagnose and confirm allergy to shrimp.

The aim of this review is to present the shrimps (wild and cultured) lipid composition (focusing on the presence of lipid classes commonly found in shrimps) and carotenoids, as well as the PUFA/SFA, ω-3/ω-6 and EPA/DHA fatty acid ratios, in order to evaluate their fat nutritional value. Furthermore, certain aspects of the structures of natural phospholipids in the above mentioned organisms will...

A scenario-specific modeling of oil blowout from the Khark island pipelines in the Persian Gulf has been carried out to evaluate the environmental impact of oil spill on the local coast, seabed and prawns. Also, various scenarios for response actions have been considered. The analyses have been performed by SINTEF Oil Spill Contingency and Response (OSCAR), a 3-dimensional model system. At the ...

Many freshwater shrimps (Decapoda, Caridea) have amphidromous life histories, with extended planktonic larval development in the sea. Larvae either are hatched upstream to drift down to the sea or are carried and released there by females. After development, postlarvae (juveniles) must migrate back up to their adult freshwater habitat. An amphidromous life cycle thus involves long distance migr...

Hemolymph osmolality, ion concentration, acid–base balance, and immune parameters in Macrobrachium rosenbergii (15–20 g) were measured after 8 days of exposure to 0–0.3 mg l 1 trichlorfon. A significant depression in hemolymph osmolality and Cl 1 contents were observed with exposure to 0.3 mg l 1 trichlorfon. Similarly, hemolymph pH, HCO3 , and TCO2 decreased significantly when prawns were expo...

We present the first global assessment of extinction risk for a major group of freshwater invertebrates, caridean shrimps. The risk of extinction for all 763 species was assessed using the IUCN Red List criteria that include geographic ranges, habitats, ecology and past and present threats. The Indo-Malayan region holds over half of global species diversity, with a peak in Indo-China and southe...

This study investigated the effects of dietary tea tree oil (TTO) supplementation and feeding patterns on growth nonspecific immunity Macrobrachium rosenbergii. Prawns were randomly assigned into four patterns. Patterns 1 (P1) 4 (P4): prawns fed with a basal diet supplemented 100 mg/kg TTO, respectively; 2 (P2) 3 (P3): TTO at 1- 2-week intervals, respectively. A significant increase in performa...

Because seafood consumption is moderate-to-high in Spain, allergic reactions to seafood such as fish, crustacea and mollusc are fairly frequent. The clinical features of these reactions depend on the implicated species and whether the reaction is provoked by ingestion, handling or vapor inhalation. Because different species have common antigenic structures, cross-sensitization is frequent, espe...

In the present study, the effect of tributyltin (TBT) on the histopathological and hormonal changes during spermatogenesis in freshwater prawn Macrobrachium rosenbergii was documented. Three experimental concentrations such as 10, 100 and 1,000 ng/L were selected and exposed to prawns for 45 days. After TBT exposure, the reproductive activities like sperm count and sperm length were decreased w...
