A procedure is proposed by which recruit numbers and parental biomass of shrimps stocks can be derived, given a series of catch-per-effort data and estimates of a few ancillary variables. In the Gulf of Thailand, shrimp recruitment decreased with decreasing egg production, but increased with decreasing total (mainly fish) standing stock. The net result of these counteracting effects was an over...

This study was carried out for the molecular level identification of recombinant protein vaccine efficacy, by oral feeding against white spot syndrome virus infection, with the comparison of viral mRNA transcriptional levels in shrimp cells. For the determination of WSSV dilution ratio for the vaccination experiment by oral feeding, in vivo virus titration was carried out using different virus ...

Shrimp is one of commodity that has a great demand by consumers both domestically and abroad as an export commodity. There are 2 types shrimp cultivated in North Sumatra, namely Vannamei tiger prawns. Cultivation grown rapidly, replacing prawns' cultivation. The objective the study to analyse affecting production factors for cultivating shrimp. research location was determined purposively Medan...

Plasma from naıve Penaeus Õannamei juveniles lacked antibacterial factors and significantly ̈ enhanced the growth of Escherichia coli strain XL1-Blue MRF compared with sea water Ž . complex SWC nutrient medium. In contrast, plasma from prawns previously injected with both live, non pathogenic Vibrio harÕeyi strain DPEX and formalin-killed cells of V. harÕeyi strains Ž . BP04, DPEX, E. coli and s...

An assessment of heavy metal concentration in wild-captured Macrobrachium rosenbergii (giant freshwater prawns) from their natural habitat is important since it susceptible to environmental pollution due the rapid development and human activities along Sarawak River. This study aimed estimate contamination muscles, exoskeletons gills M. health risk consumption. The metals was analyzed by flame ...

This article presents the nutritional value of shrimp on the strength of its nutrient composition and daily value (DV%). With its relatively lower lipid content (~ 1%), the DV (%) of 100 g shrimp for an adult human is 75%, 70% and 35% for eicosapentanoic acid + docosahexanoic acid, essential amino acids (methionine, tryptophan and lysine) and protein respectively. The lower atherogenic (0.36) a...

White Spot Disease (WSD) is well known as a widespread viral disease in shrimps from 1992. Many studies focused on morphological, histopathological and epidemiological characteristic and pathogenecity of the disease but less on the determination of the severity of WSD using the histopathological features in target tissues. A generalized scheme for assigning a numerical qualitative value to sev...

This paper presents applications to several shrimp stocks of a new, computer-based set of methods for the detailed analysis of length-frequency data. These applications include the objective estimation of growth parameters, including seasonally oscillating growth, and of total mortality as estimated from length-converted catch curves and from mean lengths. A method for obtaining estimates of na...

alnus glutinosa, fraxinus excelsior and papaver rhoeas have long been used in folkloric medicine for the treatment of various ailments. as part of our continuing screening of plant extracts for activities, the extracts of a. glutinosa, f. excelsior and p. rhoeas have been screened for their antioxidant and antibacterial activities, as well as their general toxicity towards brine shrimps. among ...
