Fishery-dependent data is collected from the fishery itself, using both commercial and recreational sources. There are a variety of methods for obtaining fishery-dependent data. The most common approach is to use recorded landings. Landings are a record of the amount of fish sold and the numbers are typically reported in total weight.
During Lent, for example, Christians who abstain from eating meat, milk, and eggs consume fish. [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.
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 ...

[66] Hake Merluccius spp.) trawl fishery is the mainstay of South Africa's fishing industry, and the center of regulatory efforts. On-board observers had been the mainstay of ...
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.
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]
This code of conduct, adopted by FAO members on 31 October 1995, contains a broad set of principles and methods for developing and managing fisheries and aquaculture. A voluntary, non-binding instrument, the code is widely recognized as the global standard for settling out the aims of sustainable fisheries and aquaculture for the coming decades.
Biological control methods to manage parasites are already being used, such as cleaner fish (e.g. lumpsuckers and wrasse) to control sea lice populations in salmon farming. [19] Models are being used to help with spatial planning and siting of fish farms in order to minimize impact. [20] Aquaculture production (2019) [21]
