TAC is a fisheries management tool that sets a species-specific maximum catch level. Economic implications include stabilizing fish stock levels, securing long-term profits. Management includes scientific assessment of fish populations and regulatory enforcement.

EBFM takes a holistic approach considering all ecosystem components. It aims to maximize the economic benefits provided by marine ecosystems while preserving their health and function. Strategies include multi-species quotas and habitat conservation.

Stock rebuilding plans aim to restore fish populations to sustainable levels. Economic implications include short-term catch reduction with long-term benefits. Strategies encompass catch limits, habitat restoration, and seasonal closures.

Fishing fleet capacity refers to the size of the fishing fleet and its ability to catch fish. Economic implications include the risk of overcapitalization leading to overfishing. Management strategies include decommissioning schemes and limiting licenses.

Multispecies interactions consider the impact of fishing one species on others and the ecosystem. Economic implications involve the complexity of managing fisheries for sustainability. Strategies include EBFM and cross-species assessments.

ITQs are rights to harvest specific amounts of a fish stock that can be traded. They align economic incentives with conservation goals, seeking to prevent overfishing. Management involves allocation and enforcement of trading rules.

Input controls manage the amount of fishing effort, while output controls manage the catch. Balancing both can enhance fishery economic performance. Strategies include gear restrictions (input) and TACs (output).

Catch shares are portions of the total allowable catch allocated to individuals or groups. They provide economic incentives for conservation and can lead to more profitable fisheries. Management includes allocation methods and monitoring.

EEZ extend 200 nautical miles from the coastline of a sovereign state. Economic implications include the exclusive right to exploit marine resources, leading to increased revenue from fisheries. Management involves monitoring, controlling access, and enforcing regulations.

Promoting alternative livelihoods in fishing communities can reduce fishing pressure and provide economic diversification. Management strategies include skills training, economic incentives, and support for non-fishing businesses.

MPAs are regions where human activity is restricted to protect biodiversity. They have economic benefits through increased productivity and tourism while sustaining fish populations. Management involves surveillance, enforcement, and community engagement.

Economic rent is the profit earned in excess of the natural resource's cost. In fisheries, it can be eroded due to overfishing and competition. Management includes rights-based frameworks like ITQs and area-based management.

Fisheries enforcement ensures adherence to laws and regulations. Economic implications include maintaining fish stock health and thus the profitability of fisheries. Strategies involve patrol, surveillance, and sanctions for violations.

Fishing effort represents the amount of fishing gear used over a certain time period. It has economic implications related to resource extraction rates and fish stock health. Management strategies include limiting fishing times and gear restrictions.

Implementing closed seasons and areas helps to protect vulnerable fish during spawning or in sensitive habitats. Economically, this sustains fish populations long-term. Strategies include seasonal bans and designated no-fishing zones.

Fisheries subsidies are government actions that financially benefit the fishing industry. While they can support economic growth, they may also lead to overcapacity and overfishing. Strategies include subsidy reform to avoid harmful incentives.

Bioeconomic models combine biological and economic data to assess the sustainability and profitability of fisheries. They help inform management decisions. Strategies include model-based quotas and adaptive management.

IUU fishing undermines sustainable fisheries management, leading to economic loss and resource depletion. Strategies include international cooperation, monitoring, surveillance, and enforcement, and traceability systems.

Overfishing is catching more fish than the system can naturally replenish. It leads to reduced fish populations, economic loss, and can cause collapse of fisheries. Strategies to address overfishing include catch limits, closed seasons, and area management.

Displaced effort occurs when effort reduction in one area or fishery leads to increased effort in another, potentially leading to overfishing elsewhere. Management includes comprehensive effort controls and adaptive multi-area management.

MSY represents the largest yield that can be taken from a species' stock over an indefinite period. Over-exploiting beyond this limit can lead to economic losses and collapse of the fishery. Management strategies include quota systems and effort controls.

Fish stock assessment is the process of collecting and analyzing data to predict fish stock behavior. It guides economic decisions and helps ensure sustainable catch levels. Management strategies include regular monitoring and adapting regulations.

Recruitment overfishing occurs when the adult population is insufficient to produce offspring for replenishing stocks. This leads to long-term economic decline. Strategies include limiting catch sizes and protecting juveniles and breeding adults.

Bycatch refers to the unwanted fish and other marine creatures caught during commercial fishing. This has economic implications related to waste and ecosystem impacts. Management strategies include gear modifications, closed areas, and bycatch quotas.

Climate change affects fish distribution and productivity, with economic implications for fisheries' adaptation and resources. Strategies include flexible management systems, species redistribution tracking, and climate-resilient aquaculture.

Gear selectivity involves using fishing methods that target specific species and sizes. Economic implications include more sustainable fisheries with healthier stock sizes. Management strategies include regulating gear types and sizes.

These subsidies can increase fishing capacity, potentially leading to overfishing and stock depletion. Economic implications include short-term gains but potential long-term losses. Management involves subsidy reform and capacity reduction programs.

Aquaculture is the farming of fish, shellfish, and aquatic plants. It has growing economic significance as a supplement to wild fisheries, but raises concerns about environmental impacts. Strategies include sustainable feed practices, disease control, and habitat restoration.

Fisheries co-management involves collaboration between fishers, governments, and other stakeholders. It can lead to more sustainable and economically viable fisheries. Strategies include stakeholder involvement in decision-making and resource monitoring.
