The science says less than 100 made it to the spawning grounds and of thoes that made it the chance of them spawning successfully is low.
Latest ES numbers are estimated to be 89 fish, 43 females, 0 jacks. Only 14 carcasses were recovered so % successfully spawned is unknown but being as these were extremely stressed fish, gamete viability is expected to be poor.
Of the 17 ES females spawned at the Cultus Lake lab, 20k eggs remain. I have no doubt other early and mid summer sockeye stocks on this cycle are in just as serious a problem.
Fisheries regulations and in river FN FSC management will be worth watching 4 years from now.
