Field Investigations of the Early Life Stages of Marine Fish

摘要: Publisher Summary This chapter discusses the field investigation of early life stages marine fish. The motivations for investigations have changed little over intervening period, being mainly assessment adult spawning biomass and distribution, desire to understand how environmental variations changes in abundance other species interact regulate particular fish populations. In many cases, annual recruitment new juveniles into population is most important process governing fluctuations. factors affecting recruitment, particularly those survival eggs larvae, are therefore perceived be key importance. review chapter, progress research on fin examined. objectives studies briefly stated followed by a sampling methodology, analytical techniques, methods assessing from egg larval data. also evidence variability growth, survival, behavior relation biological physical oceanographic conditions concentrating larvae but including were relevant. Finally, match-mismatch member-vagrant hypotheses, role density-dependence stage regulation, considered light evidence.
