New research suggests 70% decline in diversity of B.C. sockeye salmon stock in past century
There are at least 13 genetically different sockeye salmon that spawn in the rivers or tributaries of the Skeena River watershed and that has not changed in 100 years, the study found. However Price and co-author John Reynolds show that the vast majority of sockeye salmon now returning to the Skeena River to spawn, some 90 per cent, are of one type that originates in the Babine River, a tributary of the Skeena River. Price says the 
predominant strain of sockeye in the Skeena River is wild, meaning fish that were not born in a hatchery or in a human controlled spawning channel, which could affect the fish’s ability to thrive as climate change and other pressures on the fish progress. >Click to read< Loss of Sockeye Diversity Threatens Skeena Salmon, Study Finds – A century ago, the Babine accounted for 68 per cent of all wild sockeye returning to the Skeena, according to the study.
