The utility model relates to an interference-free system between fishery resource evaluation equipment and a depth finder of a scientific investigation ship, and belongs to the field of marine scientific investigation. The system comprises a fishery resource acoustic evaluation device, an RS-232 to RS-485 bidirectional protocol module, an RS-485 to RS-232 bidirectional protocol module, a statement protocol converter, a signal distributor, a radar, an electronic chart and a depth finder separate display. The fishery resource acoustic evaluation equipment, the RS-232 to RS-485 bidirectional protocol module, the RS-485 to RS-232 bidirectional protocol module, the statement protocol converter and the signal distributor are sequentially in signal data transmission, and the signal distributor is in signal transmission with the radar, the electronic chart and the depth finder separate display. The fishery resource evaluation equipment of the system works independently, the acquired data image is normal, and the prob
