Mechanisms driving recruitment variability in fish: comparisons between the Laurentian Great Lakes and marine systems

摘要: In his seminal work, Hjort (in Fluctuations in the great fisheries of Northern Europe. Conseil Parmanent International Pour L’ExplorationDe LaMar. Rapports et Proces-Verbaux, 20: 1–228, 1914) observed that fish population levels fluctuatedwidely, year-class strengthwas set early life, and egg production by adults could not alone explain variability strength. These observations laid foundation for hypotheses onmechanisms driving recruitment inmarine systems.More recently, researchers have sought to strength important Laurentian Great Lakes some developed marine been transferred fish. We conducted a literature review determine applicability ofmarine toGreat fish.We found temperature, interspecific interactions, spawner effects (abundance, age, condition adults) were most factors explaining fish, whereas relatively fewer studies identified bottom-up trophodynamic or hydrodynamic as important. Next, we compared between Baltic Sea populations no statistical difference two systems, indicating may often be transferable systems. Many yet applied suggest future research on should focus forecasting climate change invasive species. Further, because are smaller more enclosed thanmarine abundant fishery-independent data, they excellent candidates hypothesis testing
