Johnston, T.A. and Kaufman, S.D. and Moles, M.D. and Wiegand, M.D. and Leggett, W.C. (2008) Effects of delayed fertilization on embryo viability in walleye Sander vitreus (Mitchill): the role of maternal effects. Journal of Fish Biology, pp. 2634-2644
Species | Development state | Trait | Primary Data | Secondary Data |
Sander vitreus | Egg | Temperature for incubation | The incubation room was held at 9°C during the fertilization trials and early incubation period (up to 10 hours after the final fertilization) then gradually increased to 12°C over the next 7 days | 9.0 °C |
Sander vitreus | Spawning conditions | Spawning season | Walleye were sampled from a lake-spawning stock from eastern Lake Ontario in the Bay of Quinte (44°OO' N; 76°40' W) on 22 April 2004 and from a riverine-spawning stock from eastern Lake Erie in the Grand River (42°52' N; 79°30' W) on 22 and 23 April 2004 | ['April'] |
