A new study published today in the Proceedings of the National Academy of Sciences says we are dramatically underestimating the role inland fisheries play in global food security.
While it's widely known that people across the world rely on freshwater fishes caught in lakes, rivers and streams to supply protein in their diet, putting a number on the global catch—or even the catch from individual fisheries—has been challenging.
Every year, countries report on all their food production and trade to the Food and Agriculture Organization (FAO) of the United Nations. These statistics are the backbone of what we know about human nutrition worldwide, and this information is used by many organizations as their basis for targeted interventions to improve food security and alleviate malnutrition.
Attention, fishing boats on the high seas, Big Brother is watching—and now he has night vision.
For the last few years, the non-profit Global Fishing Watch has tracked the movements of fishing vessels by using satellites and ship-based automated identification systems (AIS) to shed light on illegal and unreported fishing and monitor commercial fleet activities. Just last week, for example, researchers reported using the data to estimate profits brought in by vessels fishing international waters.
But the group hasn't been able to track all vessels, and neither have government officials. One challenge is that not all boats are required to use AIS. Others are, but may turn off the devices to intentionally avoid detection. That is now changing, however, as Global Fishing Watch expands its ability to tap new kinds of data.
That’s because the supply chain for seafood is both “complex” and “opaque,” said Yaxi Hu, lead author and food science PhD candidate at University of British Columbia.
Researchers used DNA bar coding testing to test 281 samples of fish sold and determined a quarter were another species altogether. Restaurants scored the highest in terms of mislabelling at 29 per cent, then grocery stores at 24 per cent and sushi bars at 22 per cent.
But there was evidence of both intentional and unintentional mislabelling. For instance, fish sold as snapper were far less valued species such as tilapia. Meanwhile, in other cases, sockeye was substituted as pink salmon where economic motivation was less likely, Hu explained.
Much of the confusion lies in vernacular, she added. For example, Canada only requires seafood labels to be generic names, which can include multi-species, Hu said, pointing to pacific snapper or rockfish being used interchangeably.
Lima - The National Fisheries Society (SNP) said today that the first anchovy fishing season in the north central zone has boosted the growth of the Peruvian economy in April, according to figures published by the National Institute of Statistics and Informatics (INEI).
The owner of the fishing association, Elena Conterno said that these figures show that they are returning to previous levels of capture of the resource, which results in a boosting of the economy of the fishing areas of the country.
According to the INEI, in April the Gross Domestic Product grew 7.81%, its best result of the last five years. In the case of the fishing sector, the advance was 81.15%, which also boosted manufacturing activity, which increased 20.33%.
Fishing deal with China would settle maritime dispute Philippines
A joint fishing agreement reportedly being discussed between China and the Philippines is deemed a significant step forward in the relations between the two countries after an old maritime sovereignty dispute.
