An in vitro study of the attachment of Vibrio pathogens to tissues of the giant tiger prawn Penaeus monodon (Fabricius, 1798) was carried out using species-specific and genus-specific monoclonal antibodies with indirect FITCimmunofluorescence microscopy. The attachment of V. alginolyticus and V. parahaemolyticus to different tissues was always stronger than the attachment of V. anguillarum, and...

Objective The West Coast Groundfish Observer Program (WCGOP) collects at-sea data from limited trawl and fixed gear fleet as well as from open access nearshore, prawn, and shrimp fleets. This information is vital for determining the amount of discard and total catch of groundfish species in this region. This report summarizes discard data collected by the West Coast Groundfish Observer Program ...

Blue-green algae, scientifically known as Cyano single-celled organisms that grow naturally in fresh not algae (eukaryotes), but are a type of bacteria the ability to synthesize chlorophyll a. Therefore, th sunlight to manufacture carbohydrates from carb process known as photosynthesis. Blue-green al pockets inside vacuoles within their cells that they in regulate their buoyancy in response to ...

The favorable influence of liming on fish/shrimp/prawn production in aquaculture ponds of soft and acid waters has been attributed to several of the effects on water quality. Liming increases the pH of bottom mud and thereby increases the availability of phosphorus added in fertilizer. Liming increases benthic production in fertilized ponds, apparently through increased nutrient availability an...

The giant freshwater prawn Macrobrachium spinipes (Schenkel, 1902) is recorded from Taiwan for the first time and extends the distribution of the species to north of the Tropic of Cancer. The Taiwanese specimens differ slightly from material from Indonesian Papua in the density of the spination of the adult second pereipods, the relative length of the ridge of the posterior submedian plate of t...

Spawning season, recruitment, and growth of the freshwater prawn Macrobrachium lamarrei were studied in a perennial wetland, northeastern Bangladesh during October 2016 to September 2017. season was estimated based on monthly variations percent ovigerous females. Recruitment using time series length-frequency distributions. We compared von Bertalanffy function (VBGF) Pauly Gaschütz (PGGF) ident...

Anti-lipopolysaccharide factor (ALF) is a type of basic protein and an important antimicrobial peptide that can bind and neutralize lipopolysaccharides (LPS). This protein shows a broad spectrum of antimicrobial activity. In this study, three forms of ALF designated as MrALF5, MrALF6, and MrALF7 were identified from giant freshwater prawn, Macrobrachium rosenbergii. MrALF5, MrALF6, and MrALF7 g...

Crustaceans is one of the most common causes of food allergies. Its persistency is life-threatening therefore, method to detect the presence of crustacean constituent in food products would be indispensable to ensure the safety. We have developed a simple and rapid method to detect the presence of crustacean residues in food products through the allergenic Pen gene. Detection method was based o...
