Eating Jellyfish Could Come to the Rescue

According to the IUCN Red List 32,000 species are threatened with extinction—everything from birds and mammals. Despite national and international efforts being gathered to protect

    1     species, we actively fish for many of them. For those seafood lovers, the news is sad, but the researchers have come up with an unusual way we can help—and it     2     eating jellyfish.

Between 2006 and 2014,92 vulnerable or threatened     3     were being caught, recorded, and sold. When they are sold, it is     4     that fish and invertebrate (无脊椎的) species are required to be     5     according to species, so consumers have no way of knowing what they’re eating.

It is stressed that only a/an     6     view of the real problem is shown. “A lot of the ‘seafood records’ are listed in groups like ‘marine fish’. Here we didn’t look at those vague records, we only looked at records where the actual species was listed — so we’ve made a huge     7     of the actual catch.

There are some ways to untie the mess we’re creating in the world’s oceans, including     8     our idea of seafood to include jellyfish. That might sound a little off the theme, but it’s not the first time scientists have suggested it as a food source.

There are other ways to help keep the lovely marine lives off the menu. “We need to improve the labelling of seafood so that consumers can have all the information to make a/an     9     choice,” conservation scientist Carissa Klein told Science Alert.

And these choices, at least in some places, are easier than you might imagine. In Australia, where the researchers are based, there’s even official guides providing the     10     future both on your table and at sea.
