[Problem] To provide a pole-and-line fishing device which prevents a fishing line from being inadvertently severed due to immediately adapting to movement of a tuna caught on a fishhook, and which allows swimming within a certain extent but can restrict wild movements. [Solution] This pole-and-line fishing device is provided with a rotary drum, a drive motor, an electromagnetic clutch, an encoder and a control unit, wherein the control unit initially causes a winding operation to be carried out with the winding torque set to a winding force 1 and, when the load increases and rotation of the rotary drum becomes a preset winding force 2 reference rotation speed, can execute an operation mode (operation mode 1) for switching to reverse torque operation in which the winding torque is set to a winding force 2 that is less than the aforementioned winding force 1, and the winding torque is increased or decreased in accordance with the increase or decrease in the rotation speed of the rotary drum.
[Problem] To prevent a fishing line from being inadvertently severed due to immediately adapting to movement of a tuna caught on a fishhook, and to allow swimming within a certain extent but can restrict wild movements. [Solution] This pole-and-line fishing device is provided with a rotary drum 37, a drive motor 7, an electromagnetic clutch 13, an encoder 45 and a control unit 51, wherein the control unit initially causes a winding operation to be carried out with the winding torque set to a winding force 1 and, when the load increases and rotation of the rotary drum becomes a preset winding force 2 reference rotation speed, executes an operation mode for switching to reverse torque operation in which the winding torque is set to a winding force 2 that is less than the aforementioned winding force 1, and the winding torque is increased or decreased in accordance with the increase or decrease in the rotation speed of the rotary drum. The ratio of winding torque increase/decrease in reverse torque operation is determined from the winding force 2, a winding force 3, which is a preset maximum torque, and a winding force 3 reference speed at which the winding force 3 is reached. The aforementioned five preset values are stored or retrieved by means of a one-touch key and an operation is performed.

The fish lamp device comprises fish lamps mounted on the ship and illuminating a sea surface, an angle changeable device for changing the elevation angle of the fish lamps, a detection means for detecting the rotating angle of the ship resulting from pitching and rolling, and a control means controlling the elevation angle of the fish lamps to a prescribed value by controlling the angle changeable device based on the rotating angle of the ship detected by the detection means.
A fishing lamp device capable of collecting fish such as cuttlefish over a wise range and catching fish efficiently, and a fishing method using it. The light source (10) of a fishing lamp device (100) is composed of three LED light sources (10a, 10b, 10c) respectively producing blue short wavelength light, green intermediate wavelength light and red long wavelength light. The LED light sources (10a, 10b, 10c) are set at respectively specified angles when fishing cuttlefish so that continuous irradiation regions are formed in the order of wavelengths -- a short-light-emission-wavelength LED light source (10a) lighting a sea surface region far from a fishing boat, an intermediate-light-emission-wavelength LED light source (10b) lighting a sea surface region contiguous to the first region, a long-light-emission-wavelength LED light source (10c) lighting a sea surface region close to the fishing boat. Accordingly, an effective irradiation range that provides a specified illuminance under sea forms incident regions that are deep in the intermediate region, and shallow in regions close to and far from the fishing boat as shown in curves A, B, c in Fig. 1.
