Use of otolith microchemical and morphological analyses for stock discrimination of Sarpa salpa on two Tunisian islands, Djerba and Kerkennah

A groundbreaking study reveals that otolith morphological and microchemical analyses can effectively distinguish between Sarpa salpa fish stocks on the Tunisian islands of Djerba and Kerkennah, marking a significant advancement in fish stock discrimination methods. The research also highlights notable differences between male and female stocks within each population, along with high fluctuating asymmetry in both populations. This dual-method approach, combining traditional morphological analysis with innovative microchemical techniques, demonstrates their complementary power in assessing fish stock dynamics, offering valuable insights for fisheries management and conservation efforts.
