“…Our findings show the great spread experimented by this species during the last 30 years, becoming the dominant species of the epibenthic megafaunal assemblages in MC in terms of both abundance and biomass. The reproductive success of C. fornicata is known to improve with higher seawater temperature, so its spread in recent years may have been favoured by rising seawater temperatures due to global warming, and this may be enhanced in the near future (Bashevkin and Pechenik, 2015;Valdizan et al, 2011). The high abundance of C. fornicata does not seem to have affected epifaunal diversity in the area, despite the expected ecological impacts as described by Blanchard (1997).…”

“…The similarity in the growth and survival values of embryos and larvae of C. pica among temperatures between 25 and 29°C agrees with that reported for Crepidula plana Say, 1822 (Lima & Pechenik, ) and Haliotis asinina (Madrones‐Ladja & Polohan, ). But other studies where wider ranges of water temperatures are tested show higher larval growth and/or survival at intermediate temperatures (Aldana, Baqueiro, & Patiño, ; Bashevkin & Pechenik, ; Chaitanawisuti et al., ; Leighton, , ; Lima & Pechenik, ; McCormick, Navas, Buckley, & Biggs, ; Velasco & Barros, ). High water temperature has been associated with increased larval metabolism (Yi & Lee, ; Zhang, Cheung, & Shin, ), pathogen proliferation (Gruffydd & Beaumont, ; Leighton, ) and lower immune response (Dang, Speck, & Benkendorff, ).…”

“…The type of diet tested did not significantly affect the growth rate (df = 2, 289, F = 2.37, p > .05), but significantly higher survival values were showed by juveniles fed with seaweeds than those maintained with multi-specific biofilm (df = 2, 32, F = 4.94, p < .05). (Aldana, Baqueiro, & Patiño, 2001;Bashevkin & Pechenik, 2015;Chaitanawisuti et al, 2012;Leighton, 1972Leighton, , 1974Lima & Pechenik, 1985;McCormick, Navas, Buckley, & Biggs, 2017;Velasco & Barros, 2008). High water temperature has been associated with increased larval metabolism (Yi & Lee, 1996;Zhang, Cheung, & Shin, 2014), pathogen proliferation (Gruffydd & Beaumont, 1972;Leighton, 1972) and lower immune response (Dang, Speck, & Benkendorff, 2012).…”

The West Indian top shell, Cittarium pica, is an endangered vetigastropod of ecological and commercial value from the Caribbean. In order to assess the use of aquaculture as a tool for its sustainable production and conservation, embryos were produced in hatchery and experimentally cultured until juveniles under different conditions. Embryos were incubated under two temperatures (25 and 29°C) and six densities (0.3, 0.6, 1.0, 4.0, 9.0 and 37.0% of bottom‐coverage). Larvae were reared under different temperatures (25 and 27°C), densities (0.5, 1, 1.5 and 10 larvae/ml) and culture systems (static and down‐welling). Post‐larvae were obtained in three different settling conditions, and the early juveniles were cultured supplying fresh seaweed (Laurencia obtusa and Padina gymnospora), natural multi‐specific biofilm and Cylindroteca sp. biofilm. The growth and survival of embryos and larvae were not affected by temperature, but they were affected by density. Higher values were obtained at low densities (<1% of embryos bottom‐coverage and <1 larvae/ml), except for the growth of larvae, which was similar among treatments. Higher larval survival was recorded using the static culture system, and higher percent of post‐larvae recovered was associated with lower density of crawling veliger (0.2 and 0.1/ml), while its higher growth rate was related to the use of biofilms with conspecific mucus and low water‐flow (50%/h). The type of food tested did not affect the juvenile growth, but higher survival was obtained in those fed with seaweed than with multi‐specific biofilm.

“…There was no juvenile mortality for any of the three species tested in that study. Longer exposures of larvae to reduced salinity did produce significant latent effects on juvenile growth in Crepidula fornicata, however, in four of the six experiments conducted by Bashevkin and Pechenik (2015), and the effects were generally negative. In one of their experiments, however, the effect was positive: juveniles grew faster than controls at reduced salinity (20 psu) if the larvae had been reared at that same reduced salinity.…”

The coming years will apparently bring increases in seawater temperatures, salinity fluctuation, and ocean acidity, along with increasing pollution levels and increasing incidences of coastal hypoxic events. We can also expect to see shifting patterns of phytoplankton abundance and nutritional quality. Many such stresses experienced early in development—even among brooded embryos—have been found to influence growth rates, survival, and other fitness characteristics following metamorphosis, sometimes for months, both in laboratory studies and in those in which juveniles were transplanted to the field. The effects are usually negative, but have been seemingly positive in a few studies. Vulnerability can vary among species, and even among the offspring from different parents. The mechanisms through which such “latent effects” are mediated are unclear: energy-balance issues and epigenetic factors—in which gene expression patterns are altered without any changes in DNA sequences—seem to be involved.
