Anglers' catches assessment during the season 1991-1992 in a French large river (the Saone).

A field survey and a telephone survey were carried out during the years 1991 and 1992, through two large samples of sport anglers fishing in the River Saone, in order to determine both their annual time of fishing and their catches weight per hour. Taking into account the zero values, and adjusting the non-zero values to a log-normal model, give a time of fishing close to 136 h/year and a catch weight per hour of 152 g/h. The numerous anglers of the River Saone (estimated to 45 600) lead to an annual catch of 950 tons of fishes, corresponding to 3.16 t/km/year or 183 kg/ha/year. These values are close to the theoretical fish production of the river.
