It is a highly specialised scientific term. Using it in everyday conversation would likely cause confusion unless speaking with a marine biologist or in an educational context.
The direct biological opposite is 'meroplankton' (temporary plankton). A broader opposite could be 'nekton' (actively swimming organisms like fish) or 'benthos' (organisms living on the sea floor).
