在38项饲养研究中测定了食粪率。在48小时内，动物消耗0 - 83%体重的粪便颗粒，所用的粪便颗粒包括多毛类Onuphis microcephala、前鳃腹足类（IIydrobiidae科）、重足类Crassos~ea uirginica、甲壳类Cdianassa major和Penueus setiferus以及telcost Mugil cephalus。提供这些颗粒的动物包括三种多毛类动物，四种腹足类动物，三种腹足类动物，七种甲壳类动物和三种telcosts。将食粪率与计算的试验动物的维持食物需求进行比较。粪食率与颗粒饲料的碳、氮含量呈正相关。本文讨论了海洋生态系统中食粪行为的潜在影响，着重讨论了食粪行为对海洋食物链能量转换效率的影响。
Rates of coprophagy were dctcrmined in 38 feeding studies. The animals consumed from 0 to 83% of their body weight in fecal pellets during 48 hr. The fecal pellets used included those of the polychaetc Onuphis microcephala, a prosobranch gastropod (family IIydrobiidae), the pclecypod Crassos~~ea uirginica, the crustaceans Cdianassa major and Penueus setiferus, and the telcost Mugil cephalus. The animals offered these pellets included three polychaetes, four gastropods, three pelecypods, seven crustaceans, and three telcosts. Coprophagy rates are compared with calculated maintenance food requirements of the test animals. Fecal ingestion rates were positively correlated with carbon and nitrogen contents of the pellets. The potential effects of coprophagy in marinc ecosystems arc discussed emphasizing the effect of coprophagy on the overall energy transFer efficiency OF marinc food chains.
