It is unclear what the natural state of
northern abalone populations may have
been historically. There may have been
many population fluctuations over time,
which may have been related to changes
that affected the entire community. For

from the southeast Queen Charlotte Islands (Haida Gwaii) and the central coast of
British Columbia every 3-5 years from 1978 to 2007. Since 1978, abalone densities
have declined by 83% on the central coast and by 81% in th ...

Fisheries management draws on fisheries science in order to find ways to protect fishery resources so sustainable exploitation is possible. Modern fisheries management is often referred to as a governmental system of appropriate management rules based on defined objectives and a mix of management means to implement the rules, which are put in place by a system of monitoring control and surveillance. According to the FAO, there are ""no clear and generally accepted definitions of fisheries management"". However, the working definition used by the FAO and much cited elsewhere is: The integrated process of information gathering, analysis, planning, consultation, decision-making, allocation of resources and formulation and implementation, with enforcement as necessary, of regulations or rules which govern fisheries activities in order to ensure the continued productivity of the resources and the accomplishment of other fisheries objectives.
