摘要: Atlantic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus ) on Georges Bank are subjected to a high degree of variability in temperature, turbulence, prey densities, depending when they spawned where advected. We have developed an individual-based model that includes the effect varying density, temperature. Temperature effects were included by using Q10-type adjustment standard metabolic rate as well second temperature-dependent term added overall ingestion ability our fish, function swimming speed, capture efficiency, "liveliness" fish. Three cases analyzed: (i) constant food temperature conditions, (ii) variable cycles, (iii) cycles plus turbulence. found ranges typical peak spawning season enough be limiting larval growth. The timing location crucial survival larvae. Increasing average cycle 1°C, might occur due climatological change or interannual variability, increased growth for larvae not growing previously. failed increase areas already at rates close their maximum.
