Fish that are not caught by any fisheries (i.e, they "escape" the fisheries).

The number of salmon and steelhead that return to a specified point of measurement after all natural mortality and harvest have occurred. Spawning escapement consists of those fish that survive to spawn.

Those fish that have survived all fisheries and will make up a spawning population.

The number of adult anadromous fish that escape ocean and inland harvest and return to freshwater to spawn.

Estimated number of adult salmon returning to a stream to spawn.

number of fish which escape harvest or natural mortality and return to spawn.

The number of adult fish returning to a stream that escape mortality from harvest and natural attrition, and comprise a spawning population.

The portion of an anadromous fish population that escapes the commercial and recreational fisheries and reaches the freshwater spawning grounds.

Adult fish that "escape" fishing gear to migrate upstream to spawning grounds.

a term that is used in the state hatchery system to measure the volume of fish that are tracked as they go down a river into the ocean or salt water system.

The number of adult salmon escaping harvest and returning to the spawning grounds.

The percentage of fish in a particular fishery that escape from an inshore habitat and move offshore, where they eventually spawn.

The number of adult salmon or steelhead that escape the ocean, downstream, and in-river fisheries and return upstream to spawn. For CAMP purposes, escapement is synonymous with spawner abundance. See spawner abundance.

Number of mature salmon that pass through (or escape) the fisheries and return to their rivers of origin to spawn.

The quantity of sexually mature adult salmon (typically measured by number or biomass) that successfully pass through a fishery to reach the spawning grounds. This amount reflects losses resulting from harvest, and does not reflect natural mortality, typically partitioned between enroute and pre-spawning mortality. Thus, escaped fish do not necessarily spawn successfully.

That portion of a run that is not harvested and escapes to natural or artificial spawning areas.

mechanical device that regulates movement

a device within a watch that provides periodic impulses to the balance wheel that helps to regulate time- keeping

an assembly of gears having the purpose of using energy to slow down the mechanism

The combined mechanism of balance, lever, and escape wheel, which divides the impulses coming from the going barrel into small, accurately portioned doses.

The escapement controls the mainspring by ensuring it releases its power in a fixed and timely manner. This device controls the rotation of the wheels and thus the motion of the hands.

The escapement is a group of parts that allow the release of mainspring power through the rotary motion of the watch train of wheels into the back and forth motion of the balance assembly oscillation into equal time intervals.

Controls the rotation of the wheels and movement of the hands in a mechanical movement.

Device in a mechanical movement that controls the rotation of the wheels and thus the motion of the hands.

Set of parts (escape wheel, lever, roller) which converts the rotary motion of the train into to-and-fro motion (the balance).

The escapement in a mechanical watch refers to a combination of parts including the anchor, pallets and balance wheel amongst others which translate the power of the mechanism into regular timekeeping. The escapement is responsible for the familiar ticking sound of a mechanical watch.

The portion of a watch or clock that measures beats and controls the speed of the going train.

The device in a clock that controls the action of it's movement

The mechanism that "releases" the energy that maintains the oscillations of the balance wheel.

Positioned between the train (s.) and the balance wheel and governing the rotation speed of the wheel-train wheels. In today's horology the most widespread escapement type is the lever escapement. In the past, numerous types of escapements were realized, such as: verge, cylinder, pin-pallet, detent and duplex escapements. Recently, George Daniels developed a so-called "coaxial" escapement.

the device in mechanical watches, that controls operation of the movement's wheels and rotation of the hands.

A mechanical device that delivers the energy of the mainspring in small impulsesto the balance wheel, at the same time preventing the mainspring unwinding rapidly.

Term used for the type of parts that transmit power to the pendulum or other device that regulates timekeeping; such as the verge, anchor, dead beat and platform escapements.

Mechanism between the gear-train and the balance which controls the driving power and periodically gives impulse to the balance.

The mechanism in a clock or watch that allows energy to be released in discrete second bursts rather than all in one go. More information: escapements

The escapement drives the pendulum in a pendulum clock, usually from a gear train. The gear train is powered to provide energy into the pendulum, typically using springs or weights. Without the escapement the system would simply unwind continuously, but the escapement makes this motion periodic, controlled by the pendulum.
