If you have had fake crab on a sushi roll, you have pretty much got 90% of the way there. I will say that I don't think the spice blends used in a western sausage would do particularly well in fish. When you see fish balls or fish cakes in Asian cooking they're seasoned differently, light and a bit sweet.
