The amazing regeneration of marine life: What is the renewable potential of wild fisheries?
The management objective of wild fisheries is to produce sustainable biological, environmental and socio-economic benefits from renewable aquatic resources. Statistically, when specific aquatic organisms (such as fish, shellfish, amphibians, reptiles and marine mammals) produce an annual biological surplus and can be harvested through appropriate management without reducing future productivity Classify it as a renewable fishery.
Modern fisheries management is often referred to as a governmental system based on appropriate environmental management rules with clear objectives and encompasses a range of systems for monitoring, control and supervision.
Clear rules for fisheries management need to take into account several political and international objectives. Within these goals, governments need clear priorities to ensure sustainable biomass production, secure economic returns and increased protein production and food supply. These management objectives have grown significantly over the past few decades as a result of the impacts of climate change, the development of high-tech fisheries, and the evolution of competing political and policy priorities.
Fisheries management based on environmental ecosystems is becoming increasingly important and practical, especially in the face of a changed ecological environment.
Human Factors and Fisheries Management
The management of fisheries is actually the management of human and corporate behavior, and it is crucial to understand how fishermen and harvesters respond to management measures. Effective management involves encouraging the participation of all stakeholders and making community members feel empowered to contribute to the future of the fishery. However, there are limits. Corruption is also one of the reasons why fisheries management fails. Corruption and bribery can affect the allocation of fishing licenses, and in small-scale fisheries, inspectors are hesitant to pay bribes.
The quality of scientific data is also an important challenge in fisheries management. According to the observation of some scientists, the main limitation of fisheries management is the lack of quality data.
Impact of climate change on fisheries
Climate change is undoubtedly having ongoing impacts on inland and offshore fisheries. Specifically, rising water temperatures, changes in nutrient flows, and changes in spawning and nursery habitats all create difficulties in resource production. These factors affect all levels of organisms, including genes, individuals, populations, and ecosystem functioning, creating challenges that fisheries scientists need to address.
Ecosystem-Based Fisheries Management
By rebuilding ecosystems, we can seek effective fisheries management. Many scientists support a holistic view of ecosystem management, arguing that the pursuit of sustainability alone is misguided. We need to acknowledge the impact of human fishing on ecosystems and point to issues such as overfishing as potential scenarios.
Marine ecologists point out that fisheries and other natural factors jointly affect the structure of fish communities and change the relationship between predators and prey, which must be paid attention to.
Future Sustainability
To ensure the future of fisheries, many countries are entering a phase of comprehensive review. Meaningful solutions, such as setting up marine protected areas to allow fish stocks to age and reproduce naturally, are becoming mainstream.
Effective fisheries management not only relies on technical means, but also needs to consider the actual needs and interests of local communities.
The success of this process not only depends on the strength of the government, but also requires the participation and help of all levels of society. Can such joint efforts promote more regenerative and sustainable management of marine living resources? It is food for thought.
