Environmental Biology of Fishes, 2011
The feeding ecology of Mustelus schmitti was studied based on analysis of stomach contents of 525 specimens collected from three research cruises carried out during October 2008 to March 2009 on the Argentinean continental shelf (34o45′S–41oS). Generalized Linear Models were used to test the effects of Geographic location, Total Length, Sex and ...

A new cestode, Echinobothrium notoguidoi n. sp., is described from the spiral intestine of the shark Mustelus schmitti, from coastal waters off Mar del Plata, Argentina. This species is distinguished from all others in the genus by a rostellar armature consisting of 2 apical groups of 31 large hooks each, arranged in 2 rows (16 anterior, 15 posterior ...

The dentition of the narrownose smooth-hound shark, Mustelus schmitti
Marine and Freshwater Research, 2014The present study provides a quantitative and qualitative analysis on the dentition of Mustelus schmitti, and estimates the tooth-replacement rate. In total, 47 males and 56 females of M. schmitti were collected on scientific trawl surveys conducted by the National Institute of Fisheries Research and Development (INIDEP) in Argentina during the months ...

Low genetic diversity and population structure of the narrownose shark (Mustelus schmitti)
Fisheries Research, 2010Abstract The narrownose smooth-hound shark Mustelus schmitti is a coastal species endemic to the Southwest Atlantic Ocean. As this species is an important fishery resource, there is interest in knowing its genetic population structure. In this study, we used mitochondrial cytochrome b gene sequences to examine the genetic structure of the ...

The knowledge of how temperature influences elasmobranchs reproductive physiology allows a better understanding of their reproductive patterns. This study describes the relationship between temperature fluctuations and the plasmatic changes of the sex steroids related to reproduction: testosterone (T), estradiol (E2) and progesterone (P4), throughout ...
