IncubWin: A Windows 95/98/NT Computer Program for Predicting Embryonic Stages in Pacific Salmon and Steelhead Trout

J.O.T Jensen and M.E. Jensen

IncubWin was developed to run on Windows 95/98/NT operating systems. The program is based on relationships between incubation temperature and embryonic development rates for eggs of Pacific salmon (chinook, Oncorhynchus tshawytscha; chum, O. keta; coho, O. kisutch; pink, O. gorbuscha; sockeye, O. nerka) and steelhead trout (O. mykiss). One hundred and fifty mathematical models for embryonic stages, for median hatching, and for maximum alevin wet weight (MAWW), ponding, or emergence have been incorporated into the program. Hence, the user can easily determine the time (i.e., in hours, days, or °C-days) it takes eggs or larvae for any of the six species to attain a specific stage of development at various temperatures. Also included in the program are digitized colour photographs of the various developmental stages. Three files are available for downloading.

  1. The setup files for this program can be obtained by downloading the file, Incubwin 2.1 setup.zip". Unzip or extract the files into a subdirectory using Winzip and then install the program by running the installation file setup.exe. This can be done by double-clicking on the setup.exe file using Windows Explorer, or by using "Add/Remove Programs" in Control Panel.
  2. In addition, a brief instructional tutorial is available as an MS PowerPoint slideshow file (IncubWinTutorial.zip). Once the file has been downloaded and unzipped or extracted using Winzip, simply open the file using PowerPoint and run the slideshow.

The figures from the instructional tutorial are also available as pages of static slides in GIF format (IncubWindf.zip). Simply unzip or extract using Winzip and the 17 GIF files can be viewed or printed in any compatible image viewing software.
