Population biology and fishery characteristics of the smooth-hound Mustelus schmitti in Anegada Bay, Argentina

Fisheries Research, 2010
The smooth-hound Mustelus schmitti is a commercially important and common target shark inhabiting the southwestern Atlantic coastal system and is usually found in shallow waters. Using experimental and artisanal fishing records, we assessed seasonal biological and demographic characteristics related to fishing of the smooth-hound and its potential ...

Effects of temperature on the reproductive physiology of female elasmobranchs: The case of the narrownose smooth-hound shark (Mustelus schmitti)

General and Comparative Endocrinology, 2019
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 ...

The diet of Mustelus schmitti in areas with and without commercial bottom trawling (Central Patagonia, Southwestern Atlantic): Is it evidence of trophic interaction with the Patagonian shrimp fishery?

Food Webs, 2021
Abstract The study compares the diet composition between juveniles and adults of the narrownose smooth-hound Mustelus schmitti in areas with and without commercial bottom trawling using stomach contents. Individuals (n = 291) were caught as by-catch by the bottom-trawl shrimp fishery and by coastal sport anglers in Central Patagonia (Southwestern ...

reproductive biology and seasonal distribution of mustelus schmitti (elasmobranchii: triakidae) in the rio de la plata oceanic front, south-western atlantic [PDF]

Journal of the Marine Biological Association of the United Kingdom, 2005
the population structure and reproductive biology of mustelus schmitti was analysed during autumn (1994, 1995) and spring (1994) in the rio de la plata oceanic front. the samples consisted mainly of adult males and immature females, indicating that nursery areas are situated elsewhere.

Responses of aquaculture fish to climate change‐induced extreme temperatures: A review

Journal of the World Aquaculture Society, Volume 53, Issue 2, Page 314-366, April 2022., 2022
Abstract Climate change‐induced extreme temperature events are becoming more intense and frequent. For fish, temperature is the master abiotic factor that controls and limits fish development and physiology at all stages of aquaculture. Major physiological constraints at the individual level underpin changes in fish growth, hemato‐physiology ...

Tagging, ranging patterns, and behavior of franciscana dolphins (Pontoporia blainvillei) off Argentina and Brazil: Considerations for conservation

Marine Mammal Science, Volume 38, Issue 2, Page 571-605, April 2022., 2022
Abstract The franciscana dolphin, Pontoporia blainvillei, is one of the most threatened cetaceans in the Southwestern Atlantic. Within their limited coastal range off Argentina, Uruguay, and Brazil, franciscanas face human activities, including artisanal gillnet fishing and coastal development.
