The results show that the RNA/DNA ratio can be used to analyze the instantaneous growth and population health of sharks
The values showed a tendency to decrease in relation to an increase in body size in both sexes
Summary
El tiburón viuda virma Mustelus canis es una especie demersal que habita en las plataformas continentales e insulares de las zonas templadas y tropicales. The smooth dogfish shark, Mustelus canis, is a demersal species inhabiting the continental and insular shelves of temperate and tropical areas. It is found from the northeastern United States to Venezuela, including the Gulf of Mexico, the Caribbean Islands, southern Brazil and northern Argentina (Compagno 1984, Heemstra 1997).
