People with TMAU may have an intermittent fish-like body odor, depending on diet and the severity of their FM03 mutation.

When in a fasted state (12 ...
Likewise, some food ingredients, most noticeably fish meal or fish oil, can produce skin odor in dogs. Flatulence can be a problem for some dogs, which may be diet-related or a sign of gastrointestinal disease.

Most fish species spawn eggs that are fertilized externally, typically with the male inseminating the eggs after the female lays them.
