Slide and Fishway

But before we dive into the details, let’s take a moment to consider the athletic performance accomplished by at least some populations…

The Salmon of the Yukon River C.H. Gilbert. 1922. Bulletin U.S. Bureau of Fisheries 38: 317-332.

“As regards the rate at which [Chinook salmon] ascend the river, we have more reliable and complete data for the Yukon than have been secured in any other stream. Records were obtained of their first appearance at a large number of localities. … The first king salmon to reach Dawson in the middle of July, 1920, had been traveling against a consistently rapid current for 29 days, at the rate of 52 miles per day, and during this period, as always within the river, had taken no food.”

The Salmon of the Yukon River C.H. Gilbert. 1922. Bulletin U.S. Bureau of Fisheries 38: 317-332.

“[The chums] entered the river about a week later than the kings, at Tanana they were not more than 10 days behind the latter, and at Dawson they were some 14 days behind the kings. The lower 800 miles of the river, as far as Tanana, were traversed at the rate of 50 miles per day and the next 700 miles, between Tanana and Dawson, were covered at the rate of 35 miles per day.”

Collins et al. 1962 TAFS 91: 1-7

An experimental “endless fishway” was built in which salmon jumped up a series of pools and then slid back down, to test swimming performance to aid design of dams.

In five days a 50 cm sockeye salmon ascended day and night, 2025 m (6648 feet) in 415 circuits of the fishway. It was still climbing when the staff let it go. Not until the fifth day did it show signs of slowing down, and blood lactate levels did not indicate muscular fatigue.

Migration timing between and within species (some patterns and a lot of

variation)

1) Sockeye and Chinook tend to migrate and spawn early

2) Coho tend to migrate and spawn late

3) In Puget Sound pink salmon tend to spawn earlier than chum salmon but farther north this is not the case

4) Chinook and steelhead display extreme variation in migration timing among populations, and also considerable variation within populations (especially steelhead)

Counts of upstream migrating (ripe) and spent wild steelhead in two tributaries of the Siuslaw

Steelhead are commonly referred to by the season when they return to freshwater (summer or winter) but are more properly referred to by the environment where maturation takes place. Ocean maturing (= winter) steelhead arrive in late winter and spawn shortly thereafter. River maturing (= summer) steelhead arrive in late summer and spawn the following spring.

Changes in fish traits over the run • There are often systematic changes in

the life history traits of salmon over the course of the migration

• Sometimes these reflect differences in timing of discrete populations that differ in those traits

• However, sometimes there are also systematic differences within populations

Older salmon tend to arrive before younger ones (Tuluksak River, Alaska)

Why might older/larger fish and males migrate and arrive before younger/smaller

fish and females?

1) Migratory performance: bigger fish swim faster and so arrive sooner, even though they leave at the same time.

2) Feeding ecology: the optimal duration of time at sea depends on how big you are – smaller fish have a greater need to grow than larger fish.

3) Spawning ground dynamics: smaller fish cannot compete, and so arrive after bigger fish; breeding dynamics favors early arrival by males.

What time of day do salmon migrate upstream?

Primarily at night: kokanee

Lorz and Northcote 1965

Primarily in the day: Sockeye, chinook, steelhead

Columbia River

At night if the water is clear, in the day if turbid: Atlantic salmon

Hellawell et al. 1974

At night in moderate flows, in the day on floods: Atlantic salmon

Potter 1988

Slightly more at night than during the day: Atlantic salmon Brown trout

Allan 1966

What is the relationship between flow and migration?

Increases in flow stimulate migration:

Atlantic salmon Huntsman 1948, Hayes 1953, Saunders 1960, Harriman 1961, Potter 1988, Jonsson et al. 1990

rainbow trout Davies and Sloane 1987

coho salmon van den Berghe and Gross 1989

pink salmon Hunter 1959

What is the relationship between flow and migration?

Increased or high flows retard migration:

brown trout Stuart 1957, Alabaster 1970, Davies and Sloane 1987

Upriver travel can be very rapid

• Chinook – Yukon River = 36 km/day (radio tagging) – Yukon tag/recovery ~ 40 to 77 km/day – Columbia River: 1134 km at 26 km/day

(pre-dam)

Chum - Amur River: 1193 km at 45 km/day

Data sources: Brett 1995, Mathisen et al. 1988, Williams et al. 1986, Kizevetter 1948, Davidson and Shostrom 1936, etc.

Sockeye salmon were placed in a swimming tunnel, water velocity and temperature were controlled, body size was measured, and oxygen consumption and energy use were recorded after determining the swimming capacity of the fish.

Fraser River at Hell's Gate, 1897, looking upstream before the railway was built on the East Bank

At Hell’s Gate the river is so constricted that it varies by nearly 30 m during a year

Jackson. 1950. IPSFC Bull. III

Hell’s Gate • The Fraser River was probably always

hard for salmon to ascend at Hell’s Gate (and other locations).

• 1913 - dumping of rock material from railway construction virtually blocked passage of fish; millions died unspawned

• 1914 Feb. 23: a huge rockslide, caused by Canadian Northern Railway tunneling, again greatly restricted flows

Sockeye salmon blocked at Hell's Gate, 1913 www.saxvik.ca

Hell's Gate, February, 1914, after the collapse of the rock cliff above the Great Northern Railway Tunnel

Hell’s Gate: 1915 • After the slide it was virtually impassable to

fish from levels 25 to 40 feet and difficult from 10 to 60.

• Vertical drop: 9 feet (after rocks removed). • Velocity: 5.0 to 6.75 meters per second

Hell’s Gate, 1915, excavated rock from slide on east bank deposited onto rock shelf on west bank.

Hell's Gate, 1914, looking upstream, temporary fishway built on the east bank to aid adult salmon migrating up-river

Hell’s Gate

• Fishways now designed to pass 26,000 fish per hour in daylight. At the peak of the migrations they may pass over 500 salmon per minute.

• Aid passage at 10 to 70 feet elevations.

One response by salmon has been to avoid the warmer water. Columbia River sockeye are migrating earlier than in the past; steelhead are migrating later.
