Yes very interesting @suesa
I daily split the fish, but who did not notice about that you mentioned
I am a cook, of course I daily split the fish.
I just know and see parts of fish heart, liver and eggs special adult female fish.
When I read your post, I just understand what we should play on the fish, because everyone takes advantage of fish and even eat fish. I think this is a very good science for us to apply in front of children who are still at the desk study.
Good science and interesting post. thank you
