Penaeus monodon (class Crustacea, order Decapoda) is one of the largest shrimps of the Penaeidea family from the Indo-West Pacific region. The dioxygen-transporting protein hemocyanin, isolated from the hemolymph of this invertebrate, is composed of three 75-76 kDa structural/functional subunits designated as Pm1, Pm2 and Pm3. The N-terminal sequences of the chains were determined and compared ...

The depletion of three banned nitroimidazole drugs - dimetridazole (DMZ), metronidazole (MNZ) and ronidazole (RNZ) - was investigated in black tiger shrimp (Penaeus monodon) following in-water medication. The highest concentrations of residues were measured immediately after the 24-h immersion (d0). At this time, MNZ and MNZ-OH residues were measured in shrimp tissue samples at concentrations r...

Several oral vaccination studies have been undertaken to evoke a better protection against white spot syndrome virus (WSSV), a major shrimp pathogen. Formalin-inactivated virus and WSSV envelope protein VP28 were suggested as candidate vaccine components, but their uptake mechanism upon oral delivery was not elucidated. In this study the fate of these components and of live WSSV, orally intubat...

White Spot Syndrome Virus (WSSV) has been reported to cause severe mortality and economic loss in shrimp culture industry especially black tiger shrimp in worldwide. In present study, Psidium guajava Linn. root bark was serially extracted with hexane, ethyl acetate and methanol then screened antiviral activity against WSSV by incubating the extracts with WSSV infected haemolymph of Penaeus mono...

Grazers can reduce epiphytic algal loads on submerged aquatic vegetation (SAV) and indirectly alter biotic interactions among epiphytic algal groups. In the present study, we elucidate responses by 3 major epiphytic functional groups (diatoms, rhodophytes, and chlorophytes) to grass shrimp Palaemonetes spp. addition and nutrient addition during 3 growth stages of the ephemeral estuarine SAV, Ru...

This work shows an update of the sightings and reports tiger shrimp on Mexican coast Gulf Mexico recorded from 2012 to 2019 smallest specimen found in western Atlantic. The results show increase almost 300% since first report. zone with most was Campeche Yucatan. wide range size distribution captured specimens, including Atlantic presence females at advanced stage gonadal maturity, indicates th...
