Key Terms to Review (31)
Aquaculture Expansion: Aquaculture expansion refers to the growth and development of aquaculture practices to increase the production of aquatic organisms such as fish, shellfish, and plants. This expansion is crucial in addressing the rising global demand for seafood while providing a sustainable alternative to wild fishing. It involves advancements in technology, breeding, and management practices that enhance productivity and environmental sustainability in aquatic farming systems.
Artisanal fishing: Artisanal fishing refers to small-scale, traditional fishing practices that are typically carried out by local fishers using simple methods and equipment. This form of fishing is vital for local communities, providing food, income, and cultural identity while often emphasizing sustainable practices that respect marine ecosystems.
Bycatch: Bycatch refers to the unintentional capture of non-target species during fishing activities. This phenomenon often includes fish, marine mammals, birds, and other wildlife that are caught alongside the intended species, posing significant challenges for sustainability and conservation efforts in the fishing industry.
Catch Documentation Schemes: Catch documentation schemes are systems established to track and record the catch of fish and other marine species, ensuring accurate data collection for management and conservation efforts. These schemes help to verify the legal origin of catches, monitor fishing activities, and promote sustainable practices within global fishing fleets. By providing a structured approach to documenting catches, these schemes support responsible fisheries management and enhance compliance with regulations.
Catch limits: Catch limits are regulations set by authorities that determine the maximum amount of fish that can be caught within a specific time frame or area, aimed at ensuring sustainable fish populations and ecosystems. These limits are essential for managing fish stocks effectively, preventing overfishing, and maintaining biodiversity in marine environments.
Certification Schemes: Certification schemes are systems designed to verify and assure that products or practices meet specific standards of sustainability and quality. These schemes play a crucial role in promoting responsible fishing practices and ensuring the conservation of marine resources, often by providing consumers with information about the sustainability of seafood products. By establishing criteria for responsible fishing, certification schemes help enhance transparency in global fishing fleets and encourage adherence to sustainable practices.

These impacts can lead to changes in fish populations, coastal habitats, and fishing practices, significantly affecting resource management and conservation efforts.
Daniel Pauly: Daniel Pauly is a prominent marine biologist known for his significant contributions to the understanding of global fisheries and marine ecosystems. He is especially recognized for developing the concept of 'shifting baselines' in fisheries management, which highlights how perceptions of fish populations change over time, often leading to unsustainable practices. His work connects ecological principles to real-world fishing and conservation issues, making him a key figure in advocating for sustainable fisheries management.
Distant-water fleets: Distant-water fleets refer to fishing fleets that operate in oceans and seas far from their home ports, often targeting species that are not readily available in local waters. These fleets play a crucial role in global fisheries by contributing to the supply of seafood while raising concerns about overfishing and the sustainability of marine resources. The operations of distant-water fleets often involve complex international regulations and can impact local fishing communities.
Economic impact of fleets: The economic impact of fleets refers to the significant influence that fishing fleets have on local, national, and global economies through job creation, trade, and sustainable resource management. These fleets not only provide essential food sources and income for coastal communities but also contribute to international markets and fisheries management practices. Understanding this impact is crucial for balancing economic benefits with conservation efforts and sustainable fishing practices.
Fish finding equipment: Fish finding equipment refers to various technological tools and devices used by fishermen to locate and identify fish in bodies of water. This equipment enhances fishing efficiency by providing vital information such as the depth of water, water temperature, and the presence of fish schools, which can significantly improve catch rates. Understanding how to use this equipment is essential for modern fishing practices and is closely linked to sustainable fishing efforts.
Fishing quotas: Fishing quotas are regulatory limits set by authorities on the amount of specific fish species that can be caught in a given time frame, aimed at promoting sustainable fishing practices. These quotas play a vital role in managing fish populations and ensuring that commercial and recreational fishing activities do not lead to overfishing, thereby supporting long-term ecological balance and economic stability in fishing communities.
Fleet overcapacity: Fleet overcapacity refers to a situation where the fishing fleet has more vessels or fishing capacity than what is needed to sustainably harvest the available fish stocks. This imbalance often leads to excessive fishing pressure on marine resources, resulting in depleted fish populations and ecological damage. The issue is exacerbated by technological advancements that increase the efficiency of fishing methods, allowing fleets to catch more fish than can be naturally replenished.
Ghost fishing: Ghost fishing refers to the phenomenon where abandoned or lost fishing gear continues to capture marine organisms, leading to unintended and often excessive bycatch. This problem is particularly significant in trap fishing, where gear such as crab pots or fish traps can become submerged and trap animals without any fishermen to retrieve them. The consequences of ghost fishing extend to global fishing fleets, as lost gear contributes to overfishing and disrupts marine ecosystems.
Global fishing fleets: Global fishing fleets refer to the large and diverse groups of fishing vessels that operate in oceans and seas around the world, targeting various fish species for commercial and subsistence purposes. These fleets play a crucial role in the global seafood supply chain, but they also raise significant concerns regarding overfishing, sustainability, and the impact on marine ecosystems.

These areas aim to reduce human impacts, maintain biodiversity, and promote sustainable use of marine resources while providing refuge for fish populations and other marine life.
Overfishing: Overfishing occurs when fish are caught at a rate faster than they can reproduce, leading to a depletion of fish populations and disruption of marine ecosystems. This phenomenon has far-reaching consequences, influencing not only fish stocks but also the broader health of ocean environments and fishing communities.
Pole-and-line fishing: Pole-and-line fishing is a traditional and selective fishing method that utilizes a single fishing pole with a line and bait to catch fish, often targeting species like tuna. This method is known for its low environmental impact compared to more destructive practices, as it minimizes bycatch and promotes sustainability in fisheries management. The technique supports local fishing communities and encourages responsible fishing practices, making it a significant part of discussions around sustainable seafood sourcing and global fishing practices.
Purse seining: Purse seining is a fishing technique that uses a large net called a purse seine to encircle schools of fish. Once the fish are surrounded, the bottom of the net is drawn tight like a purse, trapping the fish inside for easy capture. This method is commonly used for catching large schools of fish such as tuna and sardines, and has significant implications for global fishing fleets and sustainable practices.
Regional Fisheries Management Organizations: Regional fisheries management organizations (RFMOs) are intergovernmental bodies established to manage and conserve fish stocks in specific areas of the world's oceans. These organizations play a crucial role in setting rules and regulations for fishing practices, which is essential for sustainable fishing and addressing issues like overfishing, bycatch, and international cooperation.
