A systematic and scientific estimation of the abundance of eggs (and larvae) in an area, through sampling at the bottom or in the water column with appropriate devices (e.g. small meshed midwater trawls, plankton nets). Used to estimate the size of the spawning stock and the importance of spawning.
Industry:Fishing
A pattern of fishing characterized by an increasing number of highly efficient vessels fishing at an increasing pace, with season length becoming shorter and shorter.
Industry:Fishing
A type of limited entry, an allocation to an individual (a person or a legal entity, e.g. a vessel owner or company) of a right (privilege) to harvest a certain amount of fish in a certain period of time. It is also often expressed as an individual share of an aggregate quota, or total allowable catch (TAC).
Industry:Fishing
A term referring to the study of birth rates, death rates, age distributions, and size of populations. It is a fundamental discipline within the larger field of population biology and ecology.
Industry:Fishing
A variable, a pointer, an index of a complex phenomenon. Its fluctuations reveal the variations in components of the ecosystem, the resource, or the sector. The position and trend of the indicator in relation to the criteria indicate the present state and dynamics of the system. Ideally, composite indicators are needed, the position and trajectory of which, within a system of reference of related criteria, would allow simple holistic assessment of sustainability. One can distinguish indicators of state of the system, pressure (or stress, driving forces) on the system, and response (reflecting action taken to mitigate, reduce, eliminate, or compensate for the stress).
Industry:Fishing
An organism in which humans by means of gene or cell technologies have altered the genetic material. These include the isolation, characterization, and modification of genes and their introduction into living cells or viruses of DNA, as well as techniques for the production of living cells with new combinations of genetic material by the fusion of two or more cells.
Industry:Fishing
1. The total weight of a group (or stock) of living organisms (e.g. fish, plankton) or of some defined fraction of it (e.g. spawners), in an area, at a particular time. Example: the spawning biomass of the cod stock on the Georges Bank in 1999; 2. The weight of a fish stock, or of some defined portion of it.
Industry:Fishing
A quota that each fisher or vessel is allowed to catch per trip out to sea. Trip limits are the commercial equivalent of a recreational bag limit.
Industry:Fishing
A relative measure of the abundance of a stock; for example, a time series of catch per unit effort data.
Industry:Fishing
A goal stated in the Marine Mammal Protection Act (MMPA) that the "incidental kill or incidental serious injury of marine mammals permitted in the course of commercial fishing operations be reduced to insignificant levels approaching a zero mortality and serious injury rate. "
