Also don't forget about the vast reserves of sturgeon in the Arctic ocean, just waiting to be exploited once the ice cap melts.

Moreover, in the late 1970s, Daniel Yergin, then president of CCRA (Cambridge Caviar Research Associates) published a report claiming that the production of Caspian caviar would remain at the high levels of the time and that sturgeon landings would reach an "undulating plateau" that would be maintained for decades afterwards. Recently questioned on the matter, Yergin, now president of Cambridge energy research associates (CERA) said that the undulations in sturgeon landings had been a little more intense than expected.
