This invention addresses the problem of providing a remote server that makes it possible to ascertain the yield distribution of basket clams being collected from a lake. Said remote server (5), which receives position information and operating-day information for a clam boat (4) and the basket-clam haul (weight) and fuel consumption of said clam boat (4) per operating day or per position during operating days, outputs the basket-clam haul (weight) of the clam boat (4) for each operating day and creates a yield-distribution map (56) that indicates the distribution of the basket-clam haul. The remote server (5) also: outputs, on the map, the number of times that position information for the clam boat (4) was received per operating day; and creates a collection-area distribution map (55) that indicates the distribution of areas in which basket clams were collected by the clam boat (4). |
