Sustainable fisheries need to ensure the self-recovery ability of target species

As we all know, if the over-exploitation and utilization of fishery resources exceed the resilience of the marine ecosystem itself, marine fishery resources will gradually become depleted, resulting in a global fishery crisis

Climate change a difficulty in sustainable fishery management

Not only crops, but climate change is also having a profound impact on fisheries

Mombasa is located on the southeastern coast of Kenya and is rich in marine natural resources

Kenyan climatologists say rising temperatures in shallow waters have disrupted the breeding environment of some fish, which can no longer reproduce as well as before, causing some fish to die

Through studies of ancient sediments and fossils, scientists have found that warming waters once nearly wiped out Peruvian anchovies, and they fear today's climate change could repeat the disaster

Researchers have long been concerned about the effects of climate change on wild fish populations

The 2022 United Nations Ocean Conference pointed out that the ocean provides a range of ecosystem services, provides oxygen, promotes food security, protects biodiversity, and provides the main means of transport for global trade - maritime transport, which is an important part of natural and cultural heritage.

The global ocean is facing an emergency, one-third of fish stocks are overexploited, marine biodiversity continues to decline, about half of living corals have disappeared, and invasive alien species pose a major threat to marine ecosystems and resources

It is predicted that in 2030, the global per capita fish consumption is expected to reach 21.

According to the Food and Agriculture Organization of the United Nations (FAO), global food fish consumption is expected to increase by 18% in 2030 compared to 2018.

A study on the EcoScope project for sustainable fisheries management has been published

A survey conducted by the project found that 72.

A global push for sustainable fisheries management

　　According to the FAO, the global fishery production is slowing down year by year or due to the influence of people's increasing awareness of sustainable development of fisheries.

　　Ecosystem sustainable development In the future, international, regional and national fishery management legal systems and organizational models will continue to increase and improve, becoming the guarantee and foundation for the smooth cooperation and management of global sustainable fisheries

　　Another sustainable development direction of the modern ecosystem is the improvement of technological innovation and informatization

　　Sustainable Development of Biodiversity Biodiversity sustainability is an important part of maintaining marine ecosystems.
At present, about 24.
2% of fish stocks in marine fisheries are in a state of overfishing.
In the future, it will be imperative to promote the sustainable transformation of marine fishery fishing methods.
Must do
.
For example, among the seven species of tuna with high economic value, about 33.
3% of the population is currently overfished.
In the future, purse seine and trawling will continue to be replaced by longline fishing
.
By popularizing improved fishing gear fishing methods, bycatch will generally be reduced by about 25% to 50%, and it will help to retain and screen high-value species, and improve economic efficiency and environmental sustainability
.

　　Sustainable fishery livelihood development In terms of sustainable fishery livelihoods, the United Nations has designated 2022 as the "International Year of Artisanal Fisheries and Aquaculture", and the participation of small-scale producers in sustainable resource management has become mainstream
.
Correspondingly, neglected human and labor rights in the fisheries and aquaculture value chain will also be emphasized in the future, and social security systems, laws and regulations at the national and international levels will be further implemented
.

　　Aquaculture is the leading force in the global fishery in the future.
As a major aquaculture country, China will continue to transform from extensive to intensive, adopting eco-friendly technological innovations to reduce production capacity and improve efficiency
