Toward the validation of an alternative method for endocrine monitoring in sharks: insights from testosterone analyses in the skin of bycatch individuals.

The article discusses a study that validates a new method for monitoring hormone levels in sharks. The researchers analyzed testosterone levels in the skin of sharks that were caught unintentionally as bycatch. The study found that skin biopsies can be a non-lethal and minimally invasive technique for evaluating the endocrine mechanisms in sharks. The research provides insights into the reproductive cycles and breeding success of sharks and could have implications for conservation programs. [Extracted from the article]
