Yoyo sushi

To kick-start I, Jellyfish after its temporary hiatus, feast your eyes on UK newspaper The Guardian's clever pictographic on guilt-free fish for your plate.

The message is gradually spreading that marine stocks are dwindling fast. Untamed consumption of smoked salmon blinis, not to mention our taste for deep-sea fish like the orange roughy (pictured left), are causing havoc in oceanic ecosystems. Luckily campaign groups like Fish2Fork are loudly pressurising restaurants to source their salty delicacies from sustainable suppliers, and encouraging consumers to favour restaurants with a clean conscience.

Fish2Fork have even scored big victories by causing major chains like YOSushi! to rethink their policies. Previously a major offender on Fish2Fork's blacklist, YOSushi! has done a huge u-turn in casting off endangered eel from its menu. Whether this is a decision of the heart or the PR machine, lobbying restaurants is evidently working. Heartening news when faced with as daunting a task as turning around the vast damage we're doing to the even vaster seas.
