It's that time of the week again to put your seafood knowledge to the test. Hopefully you've been doing your homework and reading IntraFish all week.

Let's see if you've been paying attention:

How did you get on:

0-3: You need to eat more oily fish - apparently it improves brain function.

3-7: Marginally better. Perhaps take a break and come back next week.

7-9: Middle of the road. Keep trying!

9-12: Sooo close. But just not quite.

12-15: Excellent work. Have a gold star.

Enjoy the weekend.
