Already in South and Southeast Asia, small fish operations are being taken over by large companies. In rural areas of developing countries, where significantly more people rely on fishing and there are fewer alternative livelihoods — the depletion of our fish life will be especially felt. Main ethical issues in fisheries. Fishing for people across the globe is not just for recreation or as a source of food, it is their way of life and how they support themselves and their family.
In the Senegalese fisheries sector overfishing has already led to 80 percent unemployment. PEW Environment Group. In the last decade, in the North Atlantic region, commercial fish populations of cod, hake, haddock and flounder have fallen by as much as 95 percent.
Experts recommend fishing be stopped to allow populations to recover. If one species declines, fisheries expand their fishing areas and efforts or simply target another species. Global fishing needs to be reduced by about 50 percent to make fisheries more economical and allow fish populations to be sustainable. Increasing effort may make some fisheries too expensive to operate.
World Ocean Review. The swordfish caught off the North American coast in the s weighed kilograms compared to kilograms today. As it becomes harder to catch large, valuable fish, fishers switch their focus and gear to take smaller and often less valuable species.
World Bank. If overfishing continues, more species will be driven to extinction and aquatic ecosystems will collapse. Fisheries should behave responsibly because they are major forces of ecological and evolutionary change. Trends in Ecology and Evolution. August Save our Seas.
Some commercially important species common before the s such as Chinese bahaba, Hong Kong grouper, Knobsnout parrotfish, and Blackspot tuskfish are now commercially extinct.
World Wildlife Fund Hong Kong. Bag limits, quotas, size limits, the implementation of licensing or seasons, and the creation of reserved or protected areas are all measures that have been used to control the amount of fish taken from local populations. Fisheries are also working to reduce bycatch by using better techniques and equipment.
Specialized traps and nets allow fisheries to reduce the amount of non-target marine life they capture. Consumers are also playing their part in protecting marine ecosystems from overfishing. As people have become aware of the seriousness of overfishing, consumers with choice are increasingly committing to buying sustainable seafood, which means fish were farmed or fished in a way that would not harm the ecosystem from which it came. Aquaculture, or fish farming, could be used to dramatically increase the supply of seafood and simultaneously reduce the environmental harm of fishing.
Farming led to humans producing more food on less land, allowing us to use less nature while also providing enough food to meet the needs of a growing population. Aquaculture is a very similar concept: rather than harvesting wild fish from marine ecosystems, populations are bred and grown in controlled conditions and harvested at a sustainable rate.
A big environmental benefit from aquaculture comes from moving fish farms from oceans to land, which reduces the impact on marine environments and allows for closed or near-closed systems where water is constantly being cleaned and recycled. Another innovation in fish farming has been the development of genetically-modified fish.
AquAdvantage salmon, developed by AquaBounty Technologies in , grows twice as fast and needs 20 percent less feed than Atlantic salmon. It also ensures protection of water resources, soil formation, nutrient storage and recycling, and the necessary breakdown of pollution.
Aside from assuring food security, marine biodiversity also provides social and socioeconomic benefits. Socioeconomically, many areas of the world rely on fisheries to survive. If fishermen cannot sell seafood, fisheries cannot purchase fish, and these ways of life are forced out of business.
A side effect of that would be that so many populations that rely on fisheries would be out of their main source of protein. Biodiversity also brings many social benefits to human populations: the opportunities to research and educate about fisheries, natural habitats, ecosystems, and various species. Marine biodiversity is incredibly important — let's take a stand against overfishing to ensure it doesn't plague eco-systems and human populations alike.
TBH, might be best to go fish-free. Green Matters is a registered trademark. Children were stricken with developmental delays due to the amount of smog The BP oil spill began on April 20, and 8 years later the area is still showing devastating effects.
In the last decade, humanity has experienced many major world issues. Little in Size, Harmful in Impact. When people hear the word microbeads, they may wonder what the term actually means. Microbeads are small pieces of plastic which are. Each day millions of people purchase drinks from a grocery or convenience store which come in plastic bottles. We may not realize it at the time, but we are affecting our oceans wi Every morning across the world, students pack a bottle of water in order to keep themselves sustained throughout the day, often in preparation for activities such as sports practic Green in Grand Finale Recap.
