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.
