The influence of temperature, salinity, body size, and sex on the bioenergetics and life-history parameters of grass shrimp (Palaemonetes pugio Holthuis) was determined under laboratory conditions. Sex and/or size show a highly significant effect only on energy allocation for metabolism. Temperature, salinity and their interaction are the main effects on most energetic parameters, with temperature showing the strongest influence on both life-history parameters and energetics. The adult grass shrimp's energy budget is different from that of larval or juvenile stages, in that most of the energy ingested by adults is allocated to reproduction. Under optimal conditions (25°C and 28‰), allocation of ingested energy in the adult grass shrimp is 51.7% for reproduction, 25.4% for respiration, 14.1% for somatic growth, 4.8% for exoskeletons, and 1.8% for excretion.  相似文献

Reproductively active ghost crabs appear to be more susceptible to oil pollution than non-active individuals, probably as a consequence of lowered energy reserves. Uptake of hydrocarbons over the 96-h exposure periods was more or less limited to the gill tissue. A relative measure—the ‘aromatic ratio’ — is suggested as a possible means of assessing bioaccumulation.  相似文献
