| Title: | The effect of ocean acidification on growth and otolith condition of juvenile scup, Stenotomus chrysops from laboratory perturbation studies from 24 Aug 2011 to 19 Oct 2011 (NODC Accession 0117506) |
| Abstract: | Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry resulting in a reduction in pH, a process termed ocean acidification. Studies have demonstrated adverse effects on calcifying organisms, particularly some invertebrates, corals, sea urchins, pteropods, and coccolithophores. It is important to determine which species are sensitive to elevated levels of CO2 because of the potential impacts to ecosystems, marine resources, biodiversity, food webs, populations and effects on human communities and economies. There have been few studies examining the effects of ocean acidification on marine fish, particularly the juvenile stages of species that support important fisheries. We examined the effects of elevated levels of CO2 on the growth, survival, otolith (ear bone) condition and the skeleton of juvenile scup, Stenotomus chrysops, a species that supports both commercial and recreational fisheries. Elevated levels of pCO2 (>1300 micro-atm) had no statistically significant effect on growth, survival, or otolith condition after 8 weeks of rearing. There was a trend towards a greater gain in weight and length in scup exposed to the mid-level (1726 micro-atm) and the high level (2614 micro-atm) treatments of pCO2 when compared to the fish in the control (1205 micro-atm) treatments, but these differences were not statistically significant. X-ray analysis of the fish revealed a slightly higher incidence of hyper-ossification in the vertebrae of a few scup from the highest treatments compared to fish from the control treatments. Our results show that juvenile scup are tolerant to increases in levels of environmental pCO2, possibly due to conditions this species encounters in their naturally variable environment.
