SPRINGERBRIEFS IN BIOLOGY THE BLUEFIN TUNA FI...

This open access book is an original contribution to the knowledge on fishing and research
associated with one of the most enigmatic fish of our seas: bluefin tuna  Thunnus thynnus (L.).
Based on available evidence  it reconstructs the possible methods used to catch large spawners
in the Strait of Gibraltar thousands of years ago and describes the much more recent
overfishing that led to a great reduction in the catches of the trap fishery on the area and
the disappearance of the northern European fisheries. It is the first book to relate the
overfishing of juvenile fishes in certain areas to the decline of large spawners in other very
distant areas  revealing one of the main underlying causes of this decline  which has remained
a mystery to the fishing sector and scientists alike for over 50 years. This finding should
serve to prevent similar cases from arising in the future.
