Seabob shrimps of the genus Xiphopenaeus are important fishery resources along the Atlantic and Pacific coasts of Central and South America. The genus was considered to comprise two species: the Atlantic Xiphopenaeus kroyeri (Heller, Sitzungsber Math Naturwiss cl kaiserliche Akad Wiss Wien 45:389–426, 1862), and the Pacific Xiphopenaeus riveti (Bouvier,

Biological Journal of the Linnean Society, 2019 AbstractThe recognition of cryptic biodiversity provides valuable insights for the management of exploited species. The Atlantic seabob shrimp (Xiphopenaeus kroyeri) is a commercially important fishery resource in the Guianan ecoregion, South America. Previous research in Brazil suggested the presence of cryptic species within the genus.

Reproductive biology and recruitment of Xiphopenaeus kroyeri in a marine protected area in the Western Atlantic: implications for resource management [PDF]
Aquatic Biology, 2012 The potential of a recently established marine protected area (MPA) in the Western Atlantic, Brazil, as a 'seed production' and nursery ground for Xiphopenaeus kroyeri, an inten- sively exploited penaeid shrimp, was investigated in an attempt to reveal any future benefit of this new MPA to adjacent populations experiencing heavy exploitation.

Abstract Xiphopenaeus kroyeri (Heller, 1862) is one of the main contributors to the benthic megafauna biomass in Sao Paulo State littoral coast (Brazil). Routine respiration ( R ) and ammonia–N excretion ( U ) rates, defined as those measured during minimum but uncontrolled activity, were quantified in different-sized shrimps at stages C/D 0 , A/B,

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).
