Defining a spawning population (spotted seatrout Cynoscion nebulosus) over temporal, spatial, and demographic scales (2009, background): “…2005, Secor 2008) or if aspects of the spawning population other than biomass (e.g. demographics, condition) significantly affect egg production (Murawski et al. 2001, Marshall et al. 2003, © Inter-Research 2009 · www.int-res.com*Email: susan.barbieri@myfwc.com KEY WORDS: Fish spawning ·…”
Fishing effects on age and spatial structures undermine population stability of fishes (2009, background): “This question was investigated theoretically: for example, Murawski et al. (2001) suggested that age truncation is likely to reduce the reproductive output, Heino and Godo (2002) suggested a reduction in sustainable yield, and the pioneer work by Murphy (1967) indicated a potential elevated…”
LONG-TERM TREND IN THE MATURATION REACTION NORM OF TWO COD STOCKS (2004, background): “One explanation involves the maturation of individuals at smaller and smaller sizes, and at younger and younger ages (Hutchings 1999, Trippel 1999, Murawski et al. 2001).”
Maturity changes in Norwegian spring-spawning herring before, during, and after a major population collapse (2004, background): “Assessing these parameters in commercially exploited fish stocks is therefore of high importance (Marshall et al., 1998; Murawski et al., 2001).”
Integrating Reproductive Biology into Scientific Advice for Fisheries Management (2008, methodology): “Murawski et al. (2001) included assumptions about egg and larval viability as an extension to the standard equations used to calculate spawner per recruit (SPR).”
MATERNAL AGE AS A DETERMINANT OF LARVAL GROWTH AND SURVIVAL IN A MARINE FISH, SEBASTES MELANOPS (2004, background): “Murawski et al. (2001) provide an elegant synthesis of these effects in Atlantic cod.”
Fisheries Sustainability via Protection of Age Structure and Spatial Distribution of Fish Populations (2004, background): “Murawski et al. (2001) provide an elegant synthesis of these effects in Atlantic cod: fishing mortality rates estimated to cause a collapse in the population are markedly reduced if maternal effects on egg and larval quality are included in modeling analyses.”
Reproductive Timing in Marine Fishes: Variability, Temporal Scales, and Methods (2011, background): “However, individual variability in reproductive timing is typically not assessed in reproductive studies even though demographic trends in spawning seasonality, spawning frequency, and fecundity have been reported (eg, Murawski et al. 2001 ; Berkeley et al.”
The logic of skipped spawning in fish (2006, background): “There may be, however, effects of age and experience that modify this, e.g., among first-time spawners (Kjesbu et al. 1996; Trippel 1998; Murawski et al. 2001 ).”
Energy acquisition and allocation to egg production in relation to fish reproductive strategies (2014, background): “2008), or they may not produce eggs of the same quality as older females (Ross 1984; Murawski et al. 2001; Pankhurst et al. 2008).”
Estimating reaction norms for age and size at maturation when age at first (2004, unknown): “The latter point is considered increasingly important (Murawski et al., 2001), as it is becoming recognized that the realized fecundity may depend, in addition to the size of reproducing individuals, on their age distribution: at the same size, older females would produce more or better quality…”
Fisheries-induced trends in reaction norms for maturation in North Sea plaice (2003, unknown): “However, an increased spawning stock biomass does not necessarily lead to higher recruitment, since the effective spawning potential of a stock depends on its demographic composition (Murawski et al., 2001): when fecundity or viability of eggs and larvae are positively correlated with maternal size,”
Emerging Issues and Methodological Advances in Fisheries Reproductive Biology (2011, methodology): “2009; Jamieson 2009) as well as key papers highlighting the relationship between reproductive biology and stock sustainability (Winemiller and Rose 1992; Murawski et al. 2001; Berkeley et al. 2004; Marshall and Browman 2007a; Morgan et al. 2009; Murua et al. 2010).”
Fishery-induced demographic changes in the timing of spawning: consequences for reproductive success* (2009, background): “From Murawski et al. (2001).”
Experimental harvesting of fish populations drives genetically based shifts in body size and maturation (2013, background): “…not all biomass is equal: significant but more subtle changes associated with a reduction in biomass occur as a result of truncated age and size structure, reducing reproductive potential (Murawski et al. 2001) and increasing vulnerability to environmental perturbations (Ottersen et al. 2006).”
Life history consequences of overexploitation to population recovery in Northwest Atlantic cod (Gadus morhua) (2005, background): “Further compounding any negative effects of smaller body size on r is the potential for reduced offspring survival owing to the production of smaller eggs (Murawski et al. 2001) and increased variability in recruitment (Hutchings and Myers 1993).”
Histological analysis invalidates macroscopically determined maturity ogives of the Kattegat cod (Gadus morhua) and suggests new proxies for estimating maturity status of individual fish (2006, background): “Errors in estimating maturity ogives will lead to spurious SSB estimates, distorting the relationship between stock and recruitment (Murawski et al., 2001), and thereby increasing the variability of assessment results.”
