Book excerpt: A procedure of classification using a discriminant function analysis was developed to determine the farmed or native natal origin of Atlantic salmon juveniles in the Magaguadavic River, New Brunswick. Farmed juveniles enter this river as escapees from three commercial aquaculture hatcheries. The procedure evaluated measured scale characteristics from the first year of growth, of farmed and native juveniles of known origin, for their power as predictors of derivation. Eight scale characteristics proved to be significant predictors of origin. In a jackknife cross-validation, the function developed from the characteristics proved to be 90.3% accurate in predicting the origin of juvenile Atlantic salmon in the Magaguadavic River. The procedure was then applied to unknown origin juveniles sampled from the Magaguadavic, Waweig and Digdequash rivers in New Brunswick. All of these rivers support hatcheries. Juvenile salmon sampled in the Magaguadavic River in 1996, 1997 and 1998, were determined to be 34%, 63% and 42% of farmed origin, respectively. During 1998, 9% of the juveniles from the Digdequash River were of farmed origin, and 42% of the juveniles in the Waweig River were of farmed origin. The study indicated that substantial numbers of farmed juveniles escaped from hatcheries and occupied juvenile salmon habitat in all three rivers.

This book was released on 2017 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic winter conditions in northern streams present considerable challenges for incubating wild Atlantic salmon (Salmo salar) embryos. How these winter conditions affect embryo mortality and development in nature is poorly understood. The goals of the present study were to 1) identify abiotic variables associated with the mortality of wild salmon embryos and 2) assess the accuracy and precision of embryonic developmental prediction methods currently used for conservation and basic research purposes. Over two study years (2013-2014 and 2014-2015), embryos were reared in artificial redds in five active spawning reaches in the Miramichi River basin and mortality was quantified at two sampling events (late March, pre-freshet and late May, post-freshet). Through partial least squares regression analyses, 37.6% of the total variation in embryo mortality was explained by abiotic predictor variables from five continuous measurements of incubation conditions in each reach (water temperature, water level, dissolved oxygen, ice conditions, and substrate characteristics). Each of the five groups of predictor variables contributed uniformly to the explained variation, which suggests that mortality is influenced by multiple interacting abiotic conditions, rather than a single variable. Developmental states based on external morphology were assigned to live embryos and alevins at various points through the incubation periods. Corresponding temperature records were used to calculate predicted developmental progression using three temperature-based relative age methods (cumulative degree-days, effective degree-days, and tau somites). Embryonic development was not observed to match any of the prediction methods. However, a linear model fitting effective degree-days to assigned developmental state was suggested as a first step to improve predictions. Population-specific adjustments to parameters within the effective degree-day or tau somite methods and the inclusion of other abiotic variables are recommended. Results from the present study support a multi-faceted ecological perspective of embryonic mortality and development in nature and may provide a baseline from which to measure the impacts of further environmental change.
