Large Pelagics
A period in the 1970's was when I was involved briefly as Canadian scientific representative to ICCAT. Significant here was work done showing the true age composition of giant tunas, a first whole Atlantic cohort analysis for Bluefin tuna, and work leading to the first regulation on small bluefin by ICCAT.
