Fugitive Salmon: Assessing the Risks of Escaped Fish from Net-Pen Aquaculture (2005, background): “Atlantic cod, for example, have distinctive aggregations that are genetically differentiated and appear to have little gene flow among them ( Ruzzante et al. 2001 ).”
Warm, windy winters drive cod north and homing of spawners keeps them there (2006, background): “Areas where abundance has previously decreased due to fishing are only slowly colonized by cod from adjacent areas (Ruzzante et al. 2001).”
Influence of diet on growth, condition and reproductive capacity in Newfoundland and Labrador cod (Gadus morhua) : Insights from stable carbon isotopes (δ13C) (2007, background): “Although Labrador cod and northeast cod are managed as one stock (2J+3KL, distinct from 3Ps cod), genetic analyses suggest that these comprise distinguishable populations (Ruzzante et al., 2001).”
AQUACULTURE AND OCEAN RESOURCES: Raising Tigers of the Sea (2005, background): “At least two of the candidate species in the Gulf of Mexico (red drum and red snapper), as well as cod in the North Atlantic, have distinct subpopulations (102, 123, 130) and could therefore cause ecological harm if farmed fish escape from cages.”
Modelling recruitment and abundance of Atlantic cod, Gadus morhua, in the eastern Skagerrak-Kattegat (North Sea): evidence of severe depletion due to a prolonged period of high fishing pressure (2004, background): “Ruzzante et al. (1996, 2001) and Green and Wroblewski (2000) provide evidence of discrete cod sub-populations in the coastal waters compared to offshore populations.”
The genetic structure of Atlantic cod (Gadus morhua) around Iceland: insight from microsatellites, the Pan I locus, and tagging experiments (2006, result): “The level of genetic differentiation that we observed with the microsatellite loci is in accordance with earlier findings in cod from coastal regions ( Ruzzante et al. 2001, FST = 0.0039 to 0.0053; Beacham et al. 2002, FST = 0.0080; Knutsen et al. 2003, FST = 0.0023).”
The response of Atlantic cod (Gadus morhua) to future climate change (2005, background): “…movement of cod is supported by analysis of blood chemistry, in particular, the amount of antifreeze levels in the blood (Rose et al., 2000), genetics (Ruzzante et al., 2001), and the southward movement of many other commercial and non-commercial species (Gomes et al., 1995; Drinkwater, 2002).”
Spatial scale of genetic structuring in coastal cod Gadus morhua and geographic extent of local populations (2007, methodology): “The joint nullhypothesis of no differentiation at any locus was tested by combining the single-locus p-values by Fisher’s summation procedure, i.e. summing twice the negative logarithms of the single-locus p-values, as recommended by Ryman & Jorde (2001).”
Migratory behaviour of Atlantic cod Gadus morhua: natal homing is the prime stock-separating mechanism (2007, background): “Genetically divergent subpopulations have been identified, for instance, in the northwest Atlantic (e.g. Ruzzante et al. 2001), in Icelandic waters (Jonsdottir et al. 2001), in the North Sea (Hutchinson et al. 2001), and along the Skagerrak coast (Knutsen et al. 2003, 2004).”
Fish Population Genetics and Molecular Markers: II- Molecular Markers and Their Applications in Fisheries and Aquaculture (2003, background): “Ruzzante et al. (2001b) reported on evidence of long term stability in the geographic pattern of genetic differentiation among cod (Gadus morhua) collected from 5 spawning banks off Newfoundland and Labrador over a period spanning three decades (1964–1994) and 2 orders of magnitude of population…”
