For more than five years, Southeast’s iconic king salmon have been returning in fewer and fewer numbers. Managers with the Alaska Department of Fish and Game are recommending Chilkat, Unuk, and King Salmon River Chinooks become official “stocks of concern.”
Next year, biologists are predicting the smallest number ever of Chinook salmon returning to the Chilkat River. Brian Elliott monitors Chinook stock for Fish and Game in Haines.
“I’ve been studying Chinook on this river for twenty years,” he said. “It’s very painful to watch this happen.”
The Department is recommending Chilkat Chinook for a “stock of concern” designation. Kings from the Unuk and King Salmon rivers will also likely get the title — and new management plans that will restrict harvest.
The Board of Fish is set to approve Chilkat Chinooks as a stock of concern at their January meeting, after years of some of the lowest returns they’ve ever seen. Last year, only 1,173 kings were forecasted to spawn up the River. That’s between one and two-thirds less than managers hoped for.
“It was the lowest escapement estimate since we’ve been conducting this kind of research. This is a region-wide effect — it’s not specific to Chilkat, it’s not specific to Northern Southeast,” Elliott said. “This is a sweeping problem.”
The escapement goal represents the number of fish that need to spawn to guarantee there are enough baby fish for healthy and harvestable runs. And that’s not happening.
“Just generally in Southeast, the Department monitors eleven Chinook stocks for escapement. We only had two reach the lower bound of their escapement goals,” he said. “Two out of eleven.”
Next year’s forecast is even worse: just 1033 kings are expected to run up the Chilkat. Elliott worries that if those numbers keep dipping, Southeast king salmon won’t stop dwindling even if fishing is completely restricted.
“Despite restrictive actions in all our fisheries — we’ve really pulled back the reins on harvest — we’re still not making our escapement goals,” he said.
“That tells us this is a production problem. This is a survival problem.”
Ed Jones agreed. He’s Fish and Game’s Chinook Research Initiative Coordinator. He says baby king salmon are suffering from marine mortality.
“They’re just dying when they go into the ocean. From Southeast to the Yukon, this mortality is occurring at their first few months at sea.We surmise it’s probably something to do with water temperature and food,” he said. “But say we found out the water was too warm. It’s not like we’re going to be able to cool the water off.”
Managers can’t jump in the water and guard fish: they can only adjust the behavior of people. Giving Chinooks “stock of concern” status will give the Department new guidelines to enforce who can fish when.
ADF&G’s draft action plan includes a scale of lenient to stringent restrictions for each fishery that’s likely to see kings from the Chilkat, Unuk, or King Salmon River. Options include restrictions by gear — such as limiting mesh sizes for gillnetters — to closing fishing areas, postponing or shortening seasons, and ratcheting down bag limits.
The Board of Fish will choose which level of restriction to run with for each fishery — commercial, sport, and subsistence. They can mix, match, add, or reject elements of the draft plan, meaning new rules for catching Southeast Chinook won’t be final until the meeting is over. The board will take public comment as part of their deliberation.
Last year, sport, commercial, and subsistence fisheries all operated on restrictions, until the Department embargoed catching kings in late August. Elliott said fishermen should expect more restrictions in 2018.
“When we’re in this kind of low abundance level, every fish does matter,” he said. “We’re going to try to reduce harvest to an absolute minimum in all fisheries.”
Jones echoed those concerns. He said while it’s typical to see salmon cycle through better and worse runs, these numbers are not normal. Or at least, they didn’t use to be.
“The cycles are increasing in amplitude. What we’re seeing today is the peaks and valleys are extremely dramatic,” he said. “Unprecedented. Either unprecedented bad times, or unprecedented good times. And we haven’t seen the good time yet.”
The Board of Fish will meet January 11 – 23 in Sitka.
