The provided image is not a fishing harbor but rather an image of several tugboats docked on a body of water. The caption provided seems to be incorrect.
In the foreground are three blue and white tugboats with their cabin areas visible and a life preserver in front of one of them. There are also some thick black ropes attached to the vessels' cabins, which appear to be used for mooring or towing. On top of the cabin on the right-hand side is an additional small cabin. The image does not show any fishing activities.
In the background, there appears to be a city skyline with various large buildings. It seems that the photograph was taken in Doha, Qatar, as indicated by the caption.
The image was captured at night and shows the tugboats docked on a body of water with the city skyline visible behind them. The sky is dark, indicating it might have been taken during the evening or early morning hours. – AI vision
