A (medium- or long-term) shift in environmental conditions that impacts the productivity of a stock.
Industry:Fishing
Alternatives proposed by a fishery management council (FMC) for a proposed management action (such as annual management specifications). The alternatives are presented to the public for comment, and are voted upon at a subsequent council meeting. The options always include a "status quo" alternative; for example, maintaining the current seasons allowable biological catches (ABCs) and optimum yields (OYs).
Industry:Fishing
A sudden increase in the abundance of alga or phytoplankton resulting in a contiguous mass of highly concentrated phytoplankton in the water column.
Industry:Fishing
1. A document that describes policy measures that will be used to rebuild a fish stock that has been declared overfished1; 2. A plan that must be designed to recover stocks to the BMSY level within 10 years when they are overfished (i.e. when biomass (B) < minimum stock size threshold (MSST)).
Industry:Fishing
A level of fish harvesting that is higher than that of economic efficiency; harvesting more fish than necessary to have maximum profits for the fishery.
Industry:Fishing
Calculation or estimation of the economic value of a natural resource.
Industry:Fishing
A low, nearly flat accumulation of sediment deposited at the mouth of a river or stream, commonly triangular or fan-shaped.
Industry:Fishing
A systematic method of gathering information on fish availability and abundance in a water body with the help of sophisticated acoustic instruments, such as echo sounders and sonar, that generate ultrasonic sound for the detection of fish.
Industry:Fishing
Categories of the level of complexity of, and data available for each assessment: index of abundance (Index), yield-per-recruit analysis (Yield), analysis of the age structure of the catch (Age Structure), analysis including the relationship between recruitment and spawning stock size (Spawning Stock), and assessment that allows prediction of future (1 or 2 years ahead) stock sizes and catches (predictive).
Industry:Fishing
1. The harvest level for a species that achieves the greatest overall benefits, including economic, social, and biological considerations. Optimum yield (OY) is different from maximum sustainable yield (MSY) in that MSY considers only the biology of the species. The term includes both commercial and sport yields; 2. The amount of fish that will provide the greatest overall benefit to the Nation, particularly with respect to food production and recreational opportunities and taking into account the protection of marine ecosystems. MSY constitutes a "ceiling" for OY. OY may be lower than MSY, depending on relevant economic, social, or ecological factors. In the case of an overfished fishery, OY should provide for the rebuilding of the stock to BMSY.
