Hydroform created by convergence of surface currents that causes surface waters to sink, creating vertical and horizontal displacement of water and possibly carrying organisms to lower depths.
Industry:Fishing
The vertical column of seawater that extends from the surface to the bottom.
Industry:Fishing
Proliferation of marine plankton that is toxic and often fatal to fish. This natural phenomenon is stimulated by phosphorus and other nutrients that are discharged into waterways by human beings. The color of the tide can be red, yellow, green, or brown.
Industry:Fishing
The sampling design of a scientific survey refers to the statistical techniques and methods adopted for selecting a sample and obtaining estimates of the survey variables from the selected sample.
Industry:Fishing
Number of fish that grow to catchable size per short interval of time, divided by the number of catchable fish already present at that time. Usually given on a yearly basis; that is, the figure just described is divided by the fraction of a year represented by the "short interval" in question. This concept is used principally when the size of the vulnerable stock is not changing or is changing only slowly, since among fishes recruitment is not usually associated with stock size in the direct way in which mortality and growth are.
Industry:Fishing
Simplified representations of the fisheries complex reality. May or may not be a mathematical representation.
Industry:Fishing
The ratio of received signal to transmitted signal from an object as at 1 meter from the transmitter, expressed in decibels.
Industry:Fishing
Of an estimate: an indicator of the closeness of an estimated value (e.g. population parameter) to the actual value. It should not be confused with precision, which relates to the confidence limits (variability) of the estimate and can always be computed from the samples.
Industry:Fishing
Seasonal migration undertaken by fish, usually as part of their life history; for example, spawning run of salmon, upstream migration of shad. Fishers may refer to increased catches as a "run" of fish, a usage often independent of their migratory behavior.
Industry:Fishing
Legally restricting the number of commercial fishermen licensed to fish. Often a management agency uses this as a means of limited entry.
