I really am not a maven of Kosher. But if made with originally kosher fish, it could be kosher. I knew some kosher folks who ate that kosher bacon - it was not bad at all.
from wiki: "In the West, surimi products usually are imitation seafood products, such as crab, abalone, shrimp, calamari, and scallop. Several companies do produce surimi sausages, luncheon meats, hams, and burgers. Some examples include: Salmolux salmon burgers and SeaPak surimi ham, salami, and rolls. A patent was issued for the process of making even higher quality proteins from fish such as in the making of imitation steak from surimi. Surimi is also used to make kosher imitation shrimp and crabmeat, using only kosher fish such as pollock."
