Ecological distribution of the shrimp Pleoticus muelleri (Bate, 1888) and Artemesia longinaris Bate, 1888 (Decapoda, Penaeoidea) in the southeastern Brazilian littoral

Abstract

The relationship between species abundance and environmental factors such as the bottom water temperature and salinity, the texture and organic matter content of the sediment and the distribution of Pleoticus muelleri and Artemesia longinaris were investigated. Specimens and samples of abiotic factors were collected monthly from May 2008 to April 2010 at 4 locations in Santos Bay on the southern coast of the State of São Paulo. A shrimp boat equipped with an otter-trawl net with an 8 m mouth aperture and a mesh size of 20 mm tapering to 18 mm at the cod end was used for sampling. Shrimp abundances were compared with an analysis of variance (ANOVA). However, when the data did not follow a normal distribution, we used the Kruskal-Wallis test. The relationship between environmental factors and the abundance of individuals was assessed with a Pearson's correlation. The largest catches of individuals of both species occurred in the late spring of 2008. The greatest abundance occurred at the outer part of the bay (collection point 4). The greatest abundance of P. muelleri was associated with lower temperatures and sediments with higher clay and organic matter content, whereas for A. longinaris, there was no significant correlation with any of the abiotic factors recorded. However, the occurrence of both species was related to lower bottom temperatures associated with the intrusion of the South Atlantic Central Water in the region.

Annual, seasonal and spatial abundance of the seabob shrimp Xiphopenaeus kroyeri (Decapoda, Penaeidae) off the Southeastern coast of Brazil

“…The difference of SACW intensity between the two periods was also observed by Batista et al (2011) who studied Pleoticus muelleri and Artemesia longinaris in the same period and area of the present study. The authors stated that these two cold water species that indicate the presence of SACW in coastal areas (Castilho et al 2008a) were abundant in late spring of 2008 and in summer of 2009 but only a few specimens were captured one year later.…”

The Cabo Frio upwelling overrides geographical patterns in the population dynamics of the shrimp Artemesia longinaris Spence Bate, 1888 (Decapoda: Penaeidae)

“…The results evidenced the effects of seasonal upwelling on the local population, as also found for the speckled swimming crab Arenaeus cribrarius (Lamarck, 1818) (Andrade, Frameschi, Castilho, Costa, & Fransozo, 2014), which overrides the latitudinal trends previously Artemesia longinaris is a subantarctic species (Boschi, 2000) which is common at the Argentinean coast, inhabiting water at temperatures ranging from 7 to 23°C (Petriella & Bridi, 1992 (Dumont & D'Incao, 2008), decreasing toward the northern states, where the incidence of the species is correlated with lower bottom water temperatures (Carvalho-Batista et al, 2011;Costa et al, 2005Costa et al, , 2010. The abundance of a species tends to be higher in the center of its geographical distribution and decreases toward the edges (Brown, 1984;Brown, Mehlman, & Stevens, 1995;Enquist, Jordan, & Brown, 1995).…”

“…Artemesia longinaris is a subantarctic species (Boschi, 2000) which is common at the Argentinean coast, inhabiting water at temperatures ranging from 7 to 23°C (Petriella & Bridi, 1992). The highest abundances at the Brazilian coast were reported in Rio Grande do Sul state (Dumont & D'Incao, 2008), decreasing toward the northern states, where the incidence of the species is correlated with lower bottom water temperatures (Carvalho-Batista et al, 2011;Costa et al, 2005Costa et al, , 2010.

The complete mitochondrial genome of the Argentine red shrimp Pleoticus muelleri (Bate, 1888) (Crustacea, Decapoda, Solenoceridae)

“…Although this species is now exported in many countries, genetic study of P. muelleri has not been conducted (Batista et al. 2011 ; Azevedo and Barbosa 2016 ). As the first step, the full mitochondrial genome of P. muelleri was determined for the first time among the genus Pleoticus .…”
