PROBLEM TO BE SOLVED: To provide a fishing ground information providing device capable of suppressing overfishing and inheriting the know-how of each operator. SOLUTION: A fishing ground information providing device 30 associates operation data including fishing ground data indicating an operated fishing ground recorded in an operation diary with first identification data assigned to each operator who recorded the operation diary. The storage means 38 to be stored, the model construction means 34 for constructing a learning model including the marine weather data indicating the marine weather condition and the fishing ground data corresponding to the first identification data, and the marine weather condition on the scheduled operation date. Prediction data based on the marine weather data shown is generated, and the recommended fishing ground is estimated by analyzing the tendency of the operator's fishing ground to which the first identification data is assigned from the prediction data using the learning model. A requesting means 36 for estimating is provided, and a fishing field plotting means 37 for plotting on a map based on a recommended fishing spot corresponding to the first identification data from the fishing ground estimating means.
