  Precautionary principle A Fishery Manager's Guidebook issued in 2002 by the FAO advises that a set of working principles should be applied to "highlight the underlying key issues" of fisheries management."FAO (2002) A Fishery Manager's Guidebook - Management Measures and Their Application. Rome. . There are 8 principles that should be considered as a whole in order to best manage a fishery. The first principle focuses on the finite nature of fish stocks and how potential yields must be estimated based on the biological constraints of the population.           Fisheries law Climate change Elderly maternal fish Old, fat, female rockfish are the best producers. Traditional management practices aim to reduce the number of old, slow-growing fish, leaving more room and resources for younger, faster-growing fish. Most marine fish produce huge numbers of eggs. The assumption was that younger spawners would produce plenty of viable larvae.AAAS (2005) New Science Sheds Light on Rebuilding Fisheries However, 2005 research on rockfish shows that large, elderly females are far more important than younger fish in maintaining productive fisheries. The larvae produced by these older maternal fish grow faster, survive starvation better, and are much more likely to survive than the offspring of younger fish. Failure to account for the role of older fish may help explain recent collapses of some major US West Coast fisheries. Recovery of some stocks is expected to take decades. One way to prevent such collapses is to establish marine reserves, where fishing is not allowed and fish populations age naturally.%DIFDELCMD < %DIFDELCMD < %%% Data quality According to fisheries scientist Milo Adkison, the primary limitation in fisheries management decisions is the absence of quality data. Fisheries management decisions are often based on population models, but the models need quality data to be effective. He asserts that scientists and fishery managers would be better served with simpler models and improved data. The most reliable source for summary statistics is the FAO Fisheries Department. Ecopath Ecopath, with Ecosim (EwE), is an ecosystem modelling software suite. It was initially a NOAA initiative led by Jeffrey Polovina, later primarily developed at the UBC Fisheries Centre of the University of British Columbia. In 2007, it was named as one of the ten biggest scientific breakthroughs in NOAA's 200-year history. The citation states that Ecopath "revolutionized scientists’ ability worldwide to understand complex marine ecosystems". Behind this lies two decades of development work by Villy Christensen, Carl Walters, Daniel Pauly, and other fisheries scientists. As of 2010 there are 6000 registered users in 155 countries. Ecopath is widely used in fisheries management as a tool for modelling and visualising the complex relationships that exist in real world marine ecosystems . Human factors Managing fisheries is about managing people and businesses, and not about managing fish. Fish populations are managed by regulating the actions of people. If fisheries management is to be successful, then associated human factors, such as the reactions of fishermen, are of key importance, and need to be understood.%DIFDELCMD < %DIFDELCMD < %%% Management regulations must also consider the implications for stakeholders. Commercial fishermen rely on catches to provide for their families just as farmers rely on crops. Commercial fishing can be a traditional trade passed down from generation to generation. Most commercial fishing is based in towns built around the fishing industry; regulation changes can impact an entire town's economy. Cuts in harvest quotas can have adverse effects on the ability of fishermen to compete with the tourism industry. Effective management of fisheries includes involving all stakeholders in the fishery. To do this successfully, stakeholders need to feel empowered enough to make meaningful contributions to the management process.%DIFDELCMD < %DIFDELCMD < %%% Empowerment has a wide application but in this context it refers to a tool that gives people within the fishing communities an opportunity to shape their own future in order to cope with the impacts from large-scale commercial fishing, competition of resources, and other threats that impact fishing communities. However, there are limits to empowerment in the fisheries management process. Empowerment maintains an involvement on the part of the state in fisheries management and no matter how empowered the other stakeholders are, the success of fisheries isn't possible without the legislative powers, financial resources, educational support, and research the government provides.%DIFDELCMD < %DIFDELCMD < %%% This concept is not accepted by all, as some communities and individuals argue that the state should withdraw completely and let the local communities handle their own fishery management based on cultural traditions and established practices. Additionally, others have argued that co-management only empowers the wealthy and powerful which in turn solidifies and validates the already existing inequalities of fisheries management. Empowerment working as a function of co-management, carried out correctly, will not only enable but it will authorize individuals and communities to make meaningful contributions to fisheries management. It is a mechanism that works in a loop, where an individual gains empowerment and encouragement from being a part of the group and the collective action is only successful because of its empowered individuals. In order to effectively and successfully use empowerment as co-management, it is imperative that study programs, guidelines, reading materials, manuals, and checklists are developed and incorporated into all fisheries management.%DIFDELCMD < %DIFDELCMD < %%% Corruption Fisheries mismanagement is due, in part, to corruption. Corruption and bribery influence the number of fishing licenses that are distributed and to whom, as well as the negotiation of fishing acccess agreements. There is evidence of industrial fisheries corruption among the Small Island Developing States of the Pacific Ocean as well as the fisheries off the coast of West Africa. In small-scale fisheries, inspectors who are charged with regulating catch are bribed to give advance notice of surprise inspections and to relax enforcement standards. Some standards are not enforced at all due to bribery, while other infractions may result in smaller fines than mandated. Fishing gear seized during an investigation can also be returned in exchange for a bribe. Corruption of small-scale fisheries has been documented in South Africa and Lake Victoria .
