General situation of world fish stocks United Nations Food and Agriculture Organization (FAO)
Based on FAO’s analysis of assessed stocks in 2016 the share of fish stocks within biologically sustainable levels has exhibited a downward trend. Stocks were 90 percent sustainable in 1974. By 2013 however, this figure had dropped to 68.6 percent.
Of this 68%, 58% were fully fished, leaving no room for growth, even as global population grows to over 9 billion by 2050. Only 10.5% of fish stocks worldwide are underfished.
In total 31% of fish stocks are overfished. We catch over 90 million tons of wild fish yearly, this huge source of human nutrition must be protected.
Aquaculture & marine protection/sustainable fisheries.
World per capita fish supply reached a new record high of 20 kg per person in 2014, thanks to vigorous growth in aquaculture, which now provides half of all fish for human consumption, and to a slight improvement in the state of certain fish stocks due to improved fisheries management.
Aquaculture brings its own host of problems, but we’ll leave it to you to investigate that and write a resolution on it if you so choose.
In small communities in Baja Mexico, fisherman took it upon themselves to increase the sustainability of their fisheries. They established self policed, self studied areas of marine protection. These areas, tiny in comparison with most marine reserves, are hotspots of marine biomass and diversity. Fishermen also self regulate their fishing seasons, opening later, and closing earlier, than the Mexican government officially allows. These two policies have resulted in increased harvest and wealth for fishermen. “Today Abreojos and a few like-minded Baja communities following the same strategy catch more than 90 percent of Mexico’s abalones”
“The idea is to have like a savings account,” says José Manuel Rondero, a 35-year-old fisherman who has watched lobster and fish populations plummet.
Now he is watching them rebound. Can Baja be a model for global fisheries?
