able, an analysis encompassing the entire salmon life cycle should be required
prior to any introduction; only then can there be an objective assessment of risk
and a sound basis for designing steps to reduce that risk.
Postscript
In 1992, New Jersey Department of Environmental Protection and Enforcement
announced a decision not to pursue the proposal to stock Pacific salmonids in the
Delaware River watershed. Reasons cited in the press release included evaluation
of the findings of the Draft EIS; consideration of public comment on the proposal;
a salmon program would detract from a more immediate priority, promotion of a
warm-water fisheries program; and a salmon program would require significant
investment of resources over an extended period of time with no guarantee of
success. Additional factors contributing to the decision to withdraw the proposal
included (Versar 1992b) National Park Service (NPS) objections to introduction
of any Pacific salmonid because of conflicts with NPS management plans for two
parks on the upper Delaware River; a lack of support from other members of the
Delaware River Fish and Wildlife Management Cooperative; a NASCO exemption was unlikely to be granted for any introduction of Pacific Salmon to the east
coast; and future USFWS funding for an introduction of Pacific Salmon is unlikely because of Executive Order 11987 policy and the Nonindigenous Aquatic
Nuisance Prevention and Control Act of 1990.
One of the findings of the draft EIS that was a major factor in the decision by
NJDFGW to withdraw the stocking proposal was the low expected number of
returns revealed by the straying model. Nonetheless, the proposal to introduce
Pacific Salmon to the Delaware River basin was undoubtedly a casualty of the
changing sociopolitical climate in which it was examined.
