Lancetfish live mainly in tropical and subtropical waters but migrate as far north as subarctic areas like Alaska's Bering Sea to feed. Lancetfish are hermaphrodites, possessing both male and female sex organs simultaneously. Very little is known about lancetfish reproduction and development.

What does lancetfish taste like?

Their flesh is watery and gelatinous, although edible and reportedly sweet to taste. They are caught as bycatch by tuna fisheries and are often considered pests, taking bait intended for more valuable species. Lancetfishes have been caught on longlines as shallow as ten fathoms in Oregon and the Gulf of Mexico.

Are Lancet fish good to eat?

They're not considered a good fish for human consumption, because their muscles contain large amounts of water, making their flesh somewhat mushy. Fishermen, in fact, consider the lancetfish a "trash" fish that sometimes takes bait intended for more profitable catches such as tuna.
