The FishTick Program Interface

FishTick consists of two programs. The first program, the FishCap (for Fish Capture), detects fish and writes the frames containing fish (or all fish if that option is chosen), to a video file. The second program, FishRev (Fish Review) program allows the user to review the video file captured by the Capture program. The user can scan through the file of fish frames, identifying the species using either the mouse or user-definable short cut keys. This information is placed into a customizable Excel spreadsheet.

FishCap

The Capture program has an extensive list of parameters which can be modified. The recording rate can be set from 1 to 30 frames per second, and the number of frames captured before and after a fish passage event can be set between 0 and 30. Currently three methods of detection are provided. The first detection method (used at fishwheel applications) allows the Capture program to start capturing when a switch is tripped and stops when the switch is tripped again. The second detection method (and the one shown) is the tripwire method where the user can place up to 25 tripwires on the screen and modify their length and location. A third detection method is more sophisticated than the tripwire method and is better at reducing false detections caused by debris or turbulence in the water column.

The user has the option of recording all frames or just those frames where fish are detected. Three different drives can be selected for storage, so that if one drive fills, the program will automatically start writing to another drive. FishCap can also automatically write a copy of the recorded video to a USB flash drive. This allows for easy download of the video file. All a technician has to do is to remove the flash drive, replacing it with another flash drive, and bring the flash drive back to run through FishRev.

The Review program allows the user to review the video file created by the Capture program. The user can scan backwards or forwards through this file at a speed ranging from 1/6 frame per second to 60 frames per second. The user can also move frame by frame through the file. All controls can be operated using either the mouse or user-defined shortcut keys.

The user can use either the mouse or user-defined shortcut keys to increment or decrement the fish counters. The user can define up to 15 species to be counted. The data is stored in a spreadsheet.
