This line (0304930000) captures frozen tilapia, catfish, carp, eels, Nile perch, and snakeheads in forms not elsewhere specified — generally whole or dressed fish in retail or smaller commercial packs. The companion lines (0304931010 and 0304931090) apply when the immediate container plus contents exceeds 6.8 kg, which is the threshold separating this line from the bulk-format classifications.

Yes. Snakeheads (family Channidae) are listed as injurious wildlife under the Lacey Act, and live snakeheads are prohibited from importation into the US. Frozen snakehead product for human consumption is generally admissible, but importers should confirm that the product is processed and not live or viable, and that state-level restrictions do not apply at the destination.
