Genetic identification of the sharks Rhizoprionodon porosus and R. lalandii by PCR-RFLP and nucleotide sequence analyses of 5S rDNA
(Springer, 2009-12-01)
A molecular approach based on nuclear 5S rDNA sequence variability was applied successfully to correctly identify samples from the two Rhizoprionodon species collected in the wild or sold in markets. The sequence of the ...
Sexual development, size at maturity, size at maternity and fecundity of the blue shark Prionace glauca (Linnaeus, 1758) in the Southwest Atlantic
(Elsevier B.V., 2014-12-01)
Size at maternity and size at maturity of the blue shark Prionace glauca were studied from samples collected during ten commercial longline fishing cruises off southern Brazil and in adjacent international waters. The sharp ...
Plastic debris collars on juvenile carcharhinid sharks (Rhizoprionodon lalandii) in southwest Atlantic
(Pergamon-elsevier Science LtdOxfordInglaterra, 2002)
Movement and activity patterns of the nurse shark, Ginglymostoma cirratum, in an oceanic Marine Protected Area of the South-western Atlantic
(2016-08-19)
The movement and activity patterns of the nurse shark, Ginglymostoma cirratum, a vulnerable species off Brazil, were investigated using mark-recapture and acoustic telemetry at an oceanic insular Marine Protected Area, the ...
Rethinking use and trade of pelagic sharks from Brazil
(Elsevier B.V., 2017-11-01)
Brazil currently ranks as the 11th producer and 1st importer of shark meat around the world. Data available from the FAO software FishStatJ along with data from regional sources, such as governmental bulletins, scientific ...
Effects of body size, age and maturity stage on diet in a large shark: Ecological and applied implications
(Springer Tokyo, 2009-01)
Ontogenetic diet shifts are a widespread phenomenon among vertebrates, although their relationships with life history traits are poorly known. We analyzed the relative importance of body size, age and maturity stage as ...
A new map of the tiger shark (Galeocerdo cuvier) genetic population structure in the western Atlantic Ocean: Hypothesis of an equatorial convergence centre
(2019-05-01)
The tiger shark (Galeocerdo cuvier) is a common widespread coastal–pelagic shark species whose population genetic structure has only recently been the object of genetic studies. In this study, the tiger's shark mitochondrial ...
Preliminary age and growth of the deep-water goblin shark Mitsukurina owstoni (Jordan, 1898)
(Csiro Publishing, 2020-08-20)
Owing to poorly mineralising structures, ageing deep-water elasmobranchs requires unconventional techniques. The aim of the present study was to develop an ageing method for the goblin sharkMitsukurina owstoni(Jordan, 1898) ...
