This is the third consecutive year the group has called for a complete ban on fishing of the early salmon run to allow for its continued recovery.
The union's vice president, Chief Bob Chamberlain, says all levels of government, and particularly the Department of Fisheries and Oceans, must take immediate and meaningful steps to protect early chinook runs.
He says ensuring the recovery and restoration of the stock is important to the continued survival as indigenous peoples.
UBCIC president Grand Chief Stewart Phillip says the early chinook stocks returning through the Fraser River and into the Nicola and Thompson systems have seen drastic declines.
Phillip accuses DFO of what he calls "poor and sloppy" management of the entire Fraser system, allowing further deterioration of the river's salmon stocks.
