Haematological parameters have become important tools for monitoring natural changes as well as anthropogenic impacts on wild populations of fish. However, for holocephalans, we still have major gaps to fill regarding basic aspects of their haematology. We present the first detailed description of peripheral blood cells of the chimaera American elephantfish Callorhinchus callorynchus together with data on haematological parame...

Understanding genetic population structure and connectivity is essential for effective species‐specific management and conservation strategies. The American elephantfish Callorhinchus callorynchus is targeted and retained as incidental catch in commercial and recreational fisheries in Chile and Argentina. Its wide‐ranging distribution across southern South America may require transnational co‐operation to ensure sustainable us...

We develop a potentially widely applicable framework for analysing the vulnerability, resilience risk and exposure of chondrichthyan species to all types of anthropogenic stressors in the marine environment. The approach combines the three components of widely applied vulnerability analysis (exposure, sensitivity and adaptability) (ESA) with three components (exposure, susceptibility and productivity) (ESP) of our adaptation o...
