Morphology

spawner = spawn (transparent) = spawn + er

Standard agentive/result noun formed by adding '-er' to the verb 'spawn'; meaning 'an organism that spawns' is directly derivable.

Etymology

Spawner comes from the verb spawn, which means 'to produce eggs', plus the agent -er meaning 'one who does'. So a spawner is an animal, often a fish, that lays or releases eggs.
