Do Bluefin Tuna fish Lay Eggs?
No, bluefin tuna do not lay eggs. They are born live from their mother’s body. Eggs are a vital part of the life cycle of many species of fish, providing both a food source and a place for the young to develop and mature. For some fish, the egg stage is the only time they will ever be vulnerable and helpless. But not all fish lay eggs.
Some, like the bluefin tuna, are born live. These fish reproduce by internal fertilization, with the male injecting his sperm into the female’s body. The eggs are then incubated inside the female’s body until they are ready to hatch.
