Plaice egg mortality: can we determine survivorschip?
The daily mortality rate of cohorts of plaice eggs in the Irish Sea is estimated throughout the spawning season in 1995 and 2000, using general additive models of egg production. Daily mortality (z) was found to vary between 0.15 and 0.29. Mortality rates declined through the season in 1995 but not...
