Blue cod change. Since a number of evidence indicated that blue cod are relatively sedentary, the fishing pressure may lead to potential local depletion. Recent studies showed that the genetic differences were significant between mainland List of islands of New Zealand population and Chatham Island population. On the other hand, the differences within mainlandList of islands of New Zealand populations were limited while the pattern of the isolation by distance was detected. Further research using microsatellite DNA markers suggested that some significant genetic differences between mainland population exist which indicate the potential long-distance dispersal, but the dispersal rate is too low to
