I'm sorry, I don't know the specific 'the fisherman's daughter' full story. You can try to find it in some classic storybooks or search for it on the Internet.
In the story, the fisherman's wife was a character full of greed and discontent. She started with a simple wish for a nicer home but quickly let her desires spiral out of control. She was short - sighted, not realizing that her constant demands on the magic fish were straining the relationship between her and the fisherman. Moreover, she lacked gratitude for the blessings they already had. Her actions were driven by envy of others' more luxurious lifestyles and an inability to be happy with her own lot in life.
The fisherman releases the jinni from a bottle. At first, the jinni wants to kill the fisherman, but the fisherman tricks the jinni back into the bottle. Then, the fisherman makes the jinni promise not to harm him and to reward him instead. The jinni tells the fisherman his story of being trapped and how he was once a powerful being. Eventually, the fisherman gets his rewards from the jinni.
Well, the moral of this story is related to the concept of grasping at more than one can hold. The fisherman, when he caught the little fish, was thinking of a much larger catch. He didn't value the small but certain gain. By being overly ambitious and not accepting the present situation, he lost everything. It's a lesson about being practical and not being too greedy in life.
A fisherman caught a little fish. The little fish pleaded with the fisherman to let it go, promising to grow bigger. But the fisherman didn't listen and wanted a big fish right away, so he didn't release the little fish, and in the end, he didn't get any big fish either.
