Fish stocks indicators, which is normalized as a 0–100 proximity-to-target score, with 100 representing "at target" and 0 being furthest from the target. Stock assessments provide fisheries managers with the information that is used in the regulation of a fish stock. Biological and fisheries data are collected in a stock assessment.
Modern fisheries management is often referred to as a governmental system of appropriate environmental 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. An ecosystem approach to fisheries management has started to become a ...
Monitoring, control and surveillance (MCS), in the context of fisheries, is defined by the Food and Agriculture Organization (FAO) of the United Nations as a broadening of traditional enforcing national rules over fishing, to the support of the broader problem of fisheries management. [1]
[1] Although the Second Five-Year Agricultural Development Plan (2001-2005) laid down a number of targets to improve the yield of Ethiopia's fisheries, a number of problems remain to be overcome. Federal and state laws regarding commercial fishing did not exist until 2002/2003. This has led to localized overfishing.
The population dynamics of fisheries is used by fisheries scientists to determine sustainable yields. [1] [2] The basic accounting relation for population dynamics is the BIDE (Birth, Immigration, Death, Emigration) model, shown as: [3] N 1 = N 0 + B − D + I − E
The Coordinating Working Party on Fishery Statistics (CWP) [1] provides a mechanism to coordinate fishery statistical programmes of regional fishery bodies and other inter-governmental organizations with a remit for fishery statistics.

In fisheries and conservation biology, the catch per unit effort (CPUE) is an indirect measure of the abundance of a target species. Changes in the catch per unit effort are inferred to signify changes to the target species' true abundance. A decreasing CPUE indicates overexploitation, while an unchanging CPUE indicates sustainable harvesting. [1]
