As global biodiversity continues to decline steeply, the health and functioning of crucial ecosystems like forests, the ocean, rivers and wetlands will be affected. Industry, fishermen, aquaculturists, and consumers all need to participate in shaping the way we manage fisheries in the future.
Despite this debate and confusion, in recent years, sustainable development has been a widely accepted guiding principle for the national and international policy process.
It will require action at many levels: changes in national economic development plans and structural government reforms; changes in how fishing rights are allocated to both small-scale fishers and industrial fleets; changes in international cooperation and international trade negotiations; and better compliance with international norms.
It also symbolises the intimate connection that we have with wildlife. Demand for seafood products has doubled over the last 30 years and is projected to continue growing at 1. Climate change means that walrus, polar bears and people may soon face an ice-free Arctic ocean during the summer, unless we take urgent action now.
And we have to do that immediately; starting today. Main article: Bycatch Bycatch is the portion of the catch that is not the target species.
In general, fish tend to live near their tolerance limits of a range of factors, and as a result, increased temperature and acidity, lower dissolved oxygen and changes to salinity may have deleterious effects on their populations.
When threatened they roll into a tight ball. This influence was indicated by the addition of the word ecologically to the concept of sustainable development.
