چکیده انگلیسی
Patella ferruginea is the most endangered marine invertebrate of western Mediterranean rocky shores. After a study of one of its most important populations in the Zembra Archipelago National Park (Tunisia), a new protocol for the translocation of the species (size: 4-8â¯cm) was adopted. The first translocation was made in June 2014 in the same archipelago, where 94 specimens were moved from Zembretta to Zembra Island and marked (62 protected by cages, 20 with no cages and 60 as controls). The second translocation was performed in August 2014 (110 specimens) from Zembra to La Galite Island (185â¯km away). High mortality was registered during transport. The remaining individuals (39) were marked and placed in cages on the rocky shores of Galite Island, then monitored until November 2015. Growth and survival rates were measured in both translocated and control populations. The highest mortality rates were observed during the initial three days after translocation, especially for individuals with no cage protection. After a 697-day survey on Zembra Island, survival rates of 58%, 25% and 85% were observed for cage, no-cage and control populations, respectively. After a 457-day survey on La Galite Island, the survival rate was 18%. Limpets>6â¯cm in size had the highest survival rate among Zembra-translocated populations, whereas translocated limpets of 4-6â¯cm in size showed the highest survival rate in La Galite. The growth rates for both translocated populations were higher than the rate observed for controls. Our translocation experiment shows the importance of cage protection and initial limpet size for survival.
