Abstract
"Two computerized stock/recruitment models are presently in use for projecting Atlantic salmon returns to the St. Croix River, the Watt-Cutting model and the Goodyear-Rago model. These two models have different parameter inputs and produce different projections. This report was prepared to:
1. Examine the different purposes for which the models were developed
2. Compare the outputs of the two models with uniform stocking inputs
3. Examine the output of the Watt-Cutting model when the input parameters for fish-passage and smolt survival are altered to conform to those of the Goodyear-Rago model.

Description
This document is a research informed review of the New Brunswick and Maine Atlantic Salmon Stocking / Recruitment models on the St. Croix River.
The models being compared are the Watt-Cutting Model and the Goodyear-Rago Model
Aspects such as juvenile and marine survival rates, fish passage efficiency and mortality are considered.
The document also includes a letter from Alexis E. Knight (Project Leader, U.S. Department of the Interior, Fish and Wildlife Service, Fishery Assistance) to Walton D. Watt of Fisheries and Oceans Canada (Freshwater and Anadromous Division, Biological Sciences Branch, Scotia - Fundy Region)
