Effects of temperature on egg and larval survival of cod (Gadus morhua) and sprat (Sprattus sprattus) in the Baltic Sea – implications for stock development (2004, background): “Cushing, 1982). Poor year classes of Baltic sprat have been associated to severe winters accompanied with low water temperatures during peak spawning (Paramanne et al., 1994) and concern about negative effects of high water temperatures on egg and larval development for Baltic cod has been discussed”
Baltic cod recruitment – the impact of climate variability on key processes (2005, background): “Repeated ichthyoplankton surveys during short time intervals (5e11 days) conducted in 1987e1993 and in 1999 allowed the estimation of mortality rates from egg stage IA or IB to III by following daily production rates of specific egg cohorts (Wieland, 1995; Wieland et al., 2000b).”
Comparison of various potential fecundity models for north-east Arctic cod Gadus morhua, L. using oocyte diameter as a standardizing factor (2006, background): “*Institute of Marine Research, Nordnesgaten 5, P. O. Box 1870 Nordnes, N-5817 Bergen, Norway and ‡School of Biological Sciences, University of Aberdeen, Aberdeen AB24 2TZ, U.K. (Received 5 August 2005, Accepted 17 July 2006) To build a better data foundation for recruitment models of north-east Arct”
Thermal dynamics of ovarian maturation in Atlantic cod (Gadus Morhua) (2010, background): “However, for unknown reasons, our model does not seem suitable for the Eastern Baltic Sea cod, which may also spawn in the early autumn even though the experienced temperatures do not seem to be particularly cold (Wieland et al. 2000).”
Biophysical modeling of larval Baltic cod (Gadus morhua) growth and survival (2002, methodology): “Recruitment during the last decade depends on the production of late-hatched larvae as the main spawning season has successively changed from late spring to summer months (Wieland et al. 2000).”
Egg production of Baltic cod (Gadus morhua) in relation to variable sex ratio, maturity, and fecundity (2002, background): “Potential egg production Stock sizes were adjusted to peak spawning time, defined as the middle of the second quarter for the period 1976– 1989 and the start of third quarter during 1990–1999 to consider a shift in spawning time (Wieland et al. 2000).”
Maternal effects in rockfishes Sebastes spp.: A comparison among species (2008, background): “…studies suggest that the removal of older and larger fish by fishing causes greater fluctuations in recruitment of commercially harvested species compared to pre-harvest conditions (Marteinsdottir & Thorarinsson 1998, Secor 2000, Wieland et al. 2000, Berkeley et al. 2004a, Hsieh et al. 2006).”
Reproductive Timing in Marine Fishes: Variability, Temporal Scales, and Methods (2011, background): “Integration of these data with information on environment, the age structure and size structure of the spawning population, and estimates of birthdates and locations based on otolith microstructure is improving our understanding of reproductive success in marine fishes (Wieland et al. 2000; Wright a”
Recruitment of Baltic cod and sprat stocks: identification of critical life stages and incorporation of environmental variability into stock-recruitment relationships* (2003, background): “Up to 1989 the sampling period was April-June; thereafter it successively shifted to May-June (1990-1992) and June-August (1993-1996), corresponding to the observed shift in the cod spawning period in recent years (Wieland et al., 2000).”
Impact of 21st century climate change on the Baltic Sea fish community and fisheries (2007, background): “However, the shift in cod peak spawning time from spring to summer (Wieland et al., 2000) resulted in a decreasing predation pressure by sprat.”
Thermal niche of Atlantic cod Gadus morhua: limits, tolerance and optima (2010, unknown): “…were then averaged to calculate an overall pdf for cod in the NE Atlantic, and also for the spawning season (as identified for the Baltic Sea, Wieland et al. 2000; the Barents Sea, Kjesbu et al. 2010; the Faroes, Steingrund & Gaard 2005; Iceland, Pálsson & Thorsteinsson 2003; the North Sea,…”
