- Title
MACROALGAE SURVIVE DIGESTION BY FISHES.
- Authors

- Abstract
Small individuals (<15 cm long) of the dingfish Sicyases sanguineus consume as many as 18 seaweed species in Central Chile. Enteromorpha sp. Was the only species able to survive digestion by fish recently collected from the field. Enteromorpha compressa and Gelidium chilense also survived by tissue regeneration when offered as food in the laboratory, but only E. compressa showed stimulation of swarmer production. In general, our results on a vertebrate species reproduce previous findings on diverse invertebrate species. Since fish are highly motile, their capacity to disperse algal species by defecation might be of great ecological importance.
