The biology of Mustelus schmitti in southern Patagonia, Argentina

Journal of Fish Biology, 2000
The relationship of body weight and total length (LT) of Mustelus schmitti in southern Patagonia was different between sexes. Changes in maturity stages in males appear at larger sizes in Ría Deseado specimens than in the Mar del Plata area. Mature females ranged from 795 to 913 mm while all male specimens >759 mm LT were mature.

Tag-recapture of the Narrownose smooth-hound (Mustelus schmitti) in Buenos Aires Coastal Ecosystem (Argentina)

Marine and Fishery Sciences, 2020
The present work refers to the first results obtained on tagging and recapture in the Narrownose smooth-hound, Mustelus schmitti, along the Coastal Ecosystem off Buenos Aires Province (BCE) with the aim of describing their migratory movements. This shark is relevant not only because of its high abundance throughout the BCE but also for its commercial ...

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, Volume 108, Issue 2, Page 676-693, February 2026.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

The Overlooked Threat of Global Warming on Elasmobranch Fertility

Fish and Fisheries, Volume 27, Issue 1, Page 41-55, January 2026.
ABSTRACT Climate change is increasingly recognised as a critical threat to global biodiversity, yet its impacts on reproductive processes remain poorly understood in many marine taxa. Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes.
