Description

  The present invention is, for example, a biological catching device for catching organisms such as fish shellfish and cephalopods in water, such as a fishing tackle that has at least a fishhook and a fishing line, a kite, a crawl net, a trapping net, and the like. More specifically, the present invention relates to a biological capture tool provided with a capture unit that captures a living thing in water and an operation unit that operates the capture unit, and an underwater camera for the biological capture tool.

  This kind of living thing capture device captures underwater living things by operating a catching part which catches living things in water with an operation part. As an example, the fishing tackle will be described. An angler as an operator holds the fish on the water (specifically, it may be held directly by hand or held by a rod), and at least a fishing hook at the tip of the road line. The fisher catches the fish in the form of pulling up the fish together with the device by pulling the road line when the fish is hung on the fish hook of the device thrown into the water.

  And the angler can use the information (or empirical intuition) of the fish detectors installed on the water, or if it is very rarely visible, the visual information, By placing the device in the water while assuming the position and depth in the water, it tries to capture the creatures in the water efficiently.

  However, because that information (ie, fish detector information, experience intuition, visual information) can not capture the creatures as expected, the camera with an underwater camera attached to the tip is separate from the fishing gear An organism capturing method has been devised that captures an organism while confirming underwater information by a device photographed by an underwater camera or an underwater image in the vicinity of the device by being placed underwater (see Patent Document 1 below).

  In the present embodiment, the attachment unit 16 of the underwater camera 4 corresponds to a camera holding unit that detachably holds the underwater camera 4 and an imaging region changing unit that changes the imaging region of the underwater camera 4.

Next, an example of how to use the fishing tackle T of the present invention (fishing method) will be described.
First, a boat operator (generally referred to as a boatman) reads the swimming depth of the fish school from the display image of the TV monitor 23 for the fish detector and instructs the fisherman.

  The angler who has received an instruction from the operator has a posture parallel to the balance portion 6b of the fishing balance 6 with the posture of the underwater camera 4 attached to the device 3 as an initial posture (that is, a state including the horizontal direction in the imaging region). ) And the device 3 is thrown into the water, and the device 3 is allowed to sink using the water depth indicated by the operator as a guide.

  The angler confirms an underwater image when the device 3 sinks on the monitor 13a of the computer 13, and arranges the device 3 (strictly, the fishhook 2) at the water depth where the school of fish actually swims.

  When the actual fish school is different from the assumed fish type, the bait attached to the device 3 or the fishhook 2 is changed to that for the actual fish type.

  In addition, when the fishhook 2 is swept away by a water flow or a tidal current, the shooting area of the underwater camera 4 is changed so that the fishhook 2 or its vicinity is shot.

  In other words, the fisherman adopts such a fishing method, so that the fishhook 2 deviates from the swimming depth of the school of fish, or is using a bait for fish species that is different from the fish species that are actually swimming. Can be reliably prevented.
