Description:
Measures of physiological performance and energy metabolism were made on an estuarine mysid (Mysidopsis bahia) exposed throughout a life cycle to the defoliant DEF. EF concentrations > 0.246 ug/l reduced survival through release of the first brood. oung production was completely arrested in DEF concentrations 0.606 ug/l, while concentrations > 0.085 ug DEF/l reduced young production by the population. oncentrations 0.140 ug/l and 0.085 g/2 retarded growth rates in older juveniles and young adults, respectively, while stimulating respiration rates. oung mysids excreted less ammonia in DEF concentrations 0.085 ug/l. igher O:N ratios during maturation of DEF-exposed mysids suggest greater reliance on energy-rich lipid substrates to support elevated metabolic demands, leaving reduced lipid for reproductive reparations.
