Abstract
Atlantic cod (Gadus morhua) is an economically valuable fish native to the Atlantic Ocean, particularly off the coast of the Canadian Atlantic. Having faced major population decline historically with little relief, understanding their genetic variation may allow for better fisheries management concerning the species. Much of the genetic variation in Atlantic cod is present in chromosomal inversions, which under current methodology are expensive and difficult to identify. The objective of this study was to develop a tool to identify the inversion on linkage group 1 in Atlantic cod using diagnostic SNPs, which would make future research into the implications of these inversions between populations much more attainable. While progress has been made in understanding how this tool could be developed, no conclusive results were able to be evaluated during the period of this study.
