Fishing Mortality Rate - a measurement of the rate of removal of fish from a population by fishing. Fishing mortality rate can be reported as either annual or instantaneous. Annual mortality is the percentage of fish dying in one year. Instantaneous mortality is that percentage of fish dying at any one point in time.

Fin ray
|
|
|
a slender, rod-shaped structure that supports the membranes of the fins. There are two types of rays, soft rays and spines. Soft rays are jointed, often branches, and flexible near their tips. Spines are unjointed, unbranched, and usually sharp at the tip and stiff along the shaft.

Food Chain
|
|
|
A linear sequence of organisms that exist on successive trophic levels within a natural community, through which energy is transferred by feeding. Primary producers capture energy from the environment (through photo- or chemo-synthesis) and form the base of the food chain. Energy is then passed to primary consumers (herbivores) and on to secondary and tertiary consumers (carnivores and top carnivores) (e.g. phytoplankton -> zooplankton -> herring -> salmon -> killer whales). Once they die, these organisms are in turn consumed and their energy transferred to detrivores and decomposers.

|
A non-linear network of feeding between organisms that includes many food chains, and hence multiple organisms on each trophic level. For example, both sharks and tuna eat herring, and sharks also eat tuna. Visit and tour around the Pacific Northwest Food Web on the OceanLink Web site.
