Abstract Shells of Xiphopenaeus kroyerishrimp were submitted to mild acid and alkaline treatments to produce α chitin films, which were characterised by infrared spectroscopy. Dynamic AC operational mode atomic force microscopy (AFM) was used to image the external surface and regions of an inner surface of the cuticle. All samples were scanned in air.

Abstract Several activities, such as port and fishing operations, exploit coastal marine ecosystems around the world, creating significant environmental impact. Since these activities often overlap spatially, they can interfere with each other. This paper aims to evaluate the spatiotemporal variability in the relative abundance of the Atlantic seabob

Seabob shrimp Xiphopenaeus kroyeri is a marine species that lives in shallow waters of coastal environments, often impacted by polycyclic aromatic hydrocarbons (PAH) pollution. In the present study, seabob shrimp were exposed for 96 h to benzo[a]pyrene (BaP) at the nominal concentrations of 100, 200, 400 and 800 microg-L(-1).

Diel variation in abundance and size of the seabob shrimp Xiphopenaeus kroyeri (Crustacea, Penaeoidea) in the Ubatuba region, Southeastern Brazil [PDF]
Anais Da Academia Brasileira De Ciencias, 2010 The objective of the present study was to analyze diel variation in the abundance and size of the seabob shrimp Xiphopenaeus kroyeri in the Ubatuba region, state of São Paulo, during the year 2000. In each season of the year, collections were made in the day and at night on 9 transects at depths ranging from 2 to 40 m.

Evaluation of determinants of Xiphopenaeus kroyeri (Heller, 1862) catch abundance along a Southwest Atlantic subtropical shelf [PDF]
ICES Journal of Marine Science, 2014 Abstract Generalized linear models were applied to identify factors affecting the capture rates (catch per unit effort, cpue) of Xiphopenaeus kroyeri and to estimate time-series data with standardized abundance indices. The adjusted models revealed that the most powerful vessels (with greater HP) were up to 3.5 times more efficient than ...

We characterize the kinetic properties of a gill (Na(+), K(+))-ATPase from the pelagic marine seabob Xiphopenaeus kroyeri. Sucrose density gradient centrifugation revealed membrane fractions distributed mainly into a heavy fraction showing considerable (Na(+), K(+))-ATPase activity, but also containing mitochondrial F0F1- and Na(+)- and V-ATPases ...

The objective of this study was to analyse the differences in shape of the cephalothorax in four fishery stocks of sea-bob shrimpXiphopenaeus kroyerithat are distributed on the east coast of Brazil, applying geometric morphometry as the analytical tool. Samples were collected at the fishing ports of Caravelas (17°43′S 39°15′W), Vitória (20°15′S 40°14′W)
