This is a great question.
The answer is “Yes,” there is a difference.
So, if that is the case, you may be wondering, “Which one is tastier (or taste better to humans) ?”
The short answer is this: it is based on the following two categories
- Type of the fish
- When the fish was caught
Many Japanese fishermen and chefs say the female Octopus is tastier because of its softer meat. Its fiber is thinner than the one of the male Octopus.
However, the female Octopus may not taste better right before the spawning season. Since all the nutrition goes to its egg, the meat becomes tougher.
Unagi (freshwater eel)
It is said female is better.
Sea Bream (鯛）
The male Sea Breambefore the Spawning season develops a beautiful cherry blossom pink. The female snapper loses some of its taste as most of its nutrition goes to the eggs.
