The catch of fish, in numbers or in weight, taken by a defined unit of fishing effort. Also called: catch per effort, fishing success, availability .
Measures the relative success of fishing operations, but also can be used as a proxy for relative abundance based on the assumption that CPUE is linearly related to stock size. The use of CPUE that has not been properly standardized for temporal-spatial changes in catchability should be avoided.
the number or weight of fish caught by a unit of fishing effort; for example, 80 kilograms per hour of trawling. CPUE is often used as a measure of fish abundance.
The number or weight of fish caught by a unit of fishing effort; e.g. a catch of 80 kg per hour as the result of fishing activities by a particular commercial fisher/boat. CPUE is often used as a measure of fish abundance.
The number of fish caught by an amount of effort. Typically, effort is a combination of gear type, gear size, and length of time gear is used. Catch per unit of effort is often used as a measurement of relative abundance for a particular fish.
