Waters located well beyond the shores (beyond the edge of the nearshore or inshore waters). Part of the oceanic environment.
Industry:Fishing
The average size of a 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 maximized.
Industry:Fishing
The expected lifetime contribution to the spawning stock biomass for the average recruit, SSB/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 and rates of growth and natural mortality, all of which are also assumed to be constant.
Industry:Fishing
The number of individuals of a particular species that live within a defined area.
Industry:Fishing
The period of time during which a scientific research vessel is operated in furtherance of a scientific research project, beginning when the vessel leaves port to undertake the project and ending when the vessel completes the project as provided for in the applicable scientific research plan.
Industry:Fishing
Refers to quantities that have been adjusted to be directly comparable to a unit that is defined as the "standard" one. Nominal catch per unit effort (CPUE) is standardized to remove the effect of factors that are known not to be related to abundance.
Industry:Fishing
The upper water layer in a two-layer system that is mixed by the wind or by convection in circulation from top to bottom of the layer, extending from the water surface to the density-stability discontinuity.
Industry:Fishing
Maximum expected lifetime yield per fish recruited in the stock.
