Beware of scientific names for a management system, what one has to remember is that the goal of a management system is to optimize a particular outcome. The pride of NOAA fisheries ecosystem management is the Bering sea pollack fishery. Of course if salmon is what your interested in then the pollack fishery is an ecosystem disaster. The best example of ecosystem management is the corn fields of Iowa. Year after year the corn crop is successful. What was there before corn is of no importance and anything that might interfere with corn production has been eliminated.
