Producer surplus is defined as the difference between what producers actually receive when selling a product and the amount they would be willing to accept for a unit of the good.
Industry:Fishing
Requires that "conservation and management measures shall, to the extent practicable, (a) minimize bycatch; and (b) to the extent bycatch cannot be avoided, minimize the mortality of such bycatch". The National Marine Fisheries Service (NMFS) has defined the term "to the extent practicable" to include a consideration of the effects of reducing bycatch and bycatch mortality on the overall benefit to the Nation.
Industry:Fishing
The number and/or size of a species that a person can legally take in a day or trip. This may or may not be the same as a possession limit.
Industry:Fishing
The capacity of a population to persist in the presence of fishing. This depends on the existence of compensatory mechanisms.
Industry:Fishing
Nominal effort pertains to measures of fishing effort or vessel carrying capacity that have not been standardized. When catchability changes, e.g. through changes in gear technology, trends in nominal effort can give a misleading picture of trends in exploitation.
Industry:Fishing
Fishery in which more than one species is caught at the same time. Because of the imperfect selectivity of most fishing gears, most fisheries are "multispecies". The term is often used to refer to fisheries where more than one species is intentially sought and retained.
Industry:Fishing
Habitats in which birth rates are lower than dealth rates and emigration is lower than immigration, as applied to equilibrium populations. A more general definition is that a sink is a compartment that is a net importer of individuals.
Industry:Fishing
The average size of the fish in a year-class at the time when the instantaneous rate of natural mortality equals the instantaneous rate of growth in weight for the year-class as a whole. At this size, the biomass of the age-class is maximum.
Industry:Fishing
The potential reproductive capacity of an organism or population expressed in the number of eggs (or offspring) produced during each reproductive cycle. Fecundity usually increases with age and size. The information is used to compute spawning potential.
Industry:Fishing
The transfer of energy from the source in plants through a series of organisms with repeated eating and being eaten. At each transfer, a large proportion of the potential energy is lost as heat. The shorter the food chain (or the nearest the organism is from the beginning of the food chain), the greater the available energy which can be converted in biomass.
