Table 5 Long-term trends in (1) annual recruitment (n m⁻² at an age of 0.3, 0.8, and 1.8 year) for the 1973–2015 period (n = 43), (2) survival (% still present half a year after the age of 0.3 year, 1 year after an age of 0.8 year, and 1 year after an age of 1.8 year or more) for 15 to 40 years of the 1973–2015 period (calculated only if at least 10 m⁻² were present at the start of the period), (3) growth rate (g AFDM ind⁻¹) for the 1976–2014 period (n = 18 to 29), and (4) late-winter biomass (g AFDM m⁻²) for the 1973–2018 period (n = 46)
