1. The yield curve is the relationship between the expected yield and the level of fishing mortality or (sometimes) fishing effort; 2. Catch in weight. Catch and yield are often used interchangeably. Amount of production per unit area over a given time. A measure of agricultural production.

1. Benchmarks used to guide management objectives for achieving a desirable outcome (e.g. optimum yield, OY). Target reference points should not be exceeded on average; 2. Corresponds to a state of a fishery or a resource that is considered desirable. Management action, whether during a fishery development or a stock rebuilding process, should aim at bringing the fishery system to this level and maintaining it there. In most cases a TRP will be expressed in a desired level of output for the fishery (e.g. in terms of catch) or of fishing effort or capacity, and will be reflected as an explicit management objective for the fishery.
Industry:Fishing
1. The ability to sustain, harvest, hold, or process; 2. The maximum amount that can be produced per unit of time with existing plant and equipment, provided the availability of variable factors of production is not restricted.
Industry:Fishing
Collective term loosely applied to most commercially harvested marine fish other than salmonids, scombrids, and clupeids. Although many groundfish are demersal (e.g. yellowtail flounder, yellowfin sole), other species are semidemersal or pelagic (e.g. pollock, cod, haddock).
Industry:Fishing
1. A comparison of the economic benefits and costs of a project, policy, or regulation; 2. A comparison of the economic benefits of using a resource to the opportunity cost if the resource is used. Projects or regulations are typically evaluated based on how they change the cost-benefit ratio.
Industry:Fishing
Ecosystem services those are necessary for the production of all other ecosystem services. Some examples include biomass production, production of atmospheric oxygen, soil formation and retention, nutrient cycling, water cycling, and provisioning of habitat.
Industry:Fishing
Assimilation (gross) or accumulation (net) of energy and nutrients by green plants and by organisms that use inorganic compounds as food.
Industry:Fishing
Describes a group of fish without a hard bony skeleton, including sharks, skates, and rays.
Industry:Fishing
1. A model that estimates yield in terms of weight, but more often as a percentage of the maximum yield, for various combinations of natural mortality, fishing mortality, and time exposed to the fishery; 2. The average expected yield in weight from a single recruit. Y/R is calculated assuming that fishing mortality is constant over the life span of a year class. The calculated value is also dependent on the exploitation pattern, rate of growth, and natural mortality rate, all of which are assumed to be constant.
Industry:Fishing
An analysis required by the Regulatory Flexibility Act.
