Larvae of marine reef organisms settling into benthic habitats may vary greatly in individual quality. We evaluated potential effects of variation in larval growth rate (1 metric of quality) on larval duration, size-at-settlement, and post-settlement survival of recently settled kelp bass Paralabrax clathratus. We sampled kelp bass daily and weekly from standardized collectors located near the Wrigley Institute for Environmental Studies, Santa Catalina Island, to characterize larval traits of settlers and surviving recruits. Using growth models to fit trajectories of larval otolith growth, we estimated instantaneous larval growth rates and found that these values were good predictors of larval duration and juvenile survival. Kelp bass that grew rapidly as larvae settled ∼8.5 d sooner than the slowest growing individuals; both groups had similar sized individuals at settlement, but fast growing larvae experienced enhanced survival during the first 5 d after settlement relative to slower growing larvae. There is growing evidence suggesting that larval experience continues to exert demographic consequences on subsequent life stages. This helps to explain some of the spatial and temporal variability that characterizes recruitment in marine systems.

- Realized and potential larval connectivity in the Southern California Bight (2010, background): “Kelp bass spawn from the late spring to early fall (Erisman & Allen 2006), and their larvae spend approximately 30 d dispersing with ocean currents (Findlay & Allen 2002, Shima & Findlay 2002).”
- Three synergistic growth-related mechanisms in the short-term survival of larval Japanese anchovy Engraulis japonicus in Sagami Bay (2004, background): “Previous studies avoided this possibility by using only daily increment widths as an indicator of growth rates (e.g. Thorrold & Milicich 1990, Searcy & Sponaugle 2000, 2001, Shima & Findlay 2002).”
- Temperature-mediated variation in early life history traits and recruitment success of the coral reef fish Thalassoma bifasciatum in the Florida Keys (2006, background): “Recent studies have begun to demonstrate that, similar to temperate species (Houde 1987, Meekan & Fortier 1996, Hare & Cowen 1997, Shima & Findlay 2002), variation in the growth of larvae of tropical fishes may have important consequences for their survival (Searcy & Sponaugle 2001, Vigliola &…”
- Larval growth history determines juvenile growth and survival in a tropical marine fish (2004, background): “…studies of tropical marine fishes have shown that the advantages associated with a high larval growth rate lead to enhanced survival through to metamorphosis and settlement to the juvenile population (Searcy and Sponaugle 2001, Bergenius et al. 2002, Shima and Findlay 2002, Wilson and Meekan 2002).”
