Diet composition and feeding strategy of the southern pipefish Syngnathus folletti in a Widgeon grass bed of the Patos Lagoon Estuary, RS, Brazil Neotropical Ichthyology
Garcia,Alexandre M.; Geraldi,Ricardo M.; Vieira,João P..
Pipefish species are poorly known representatives of the family Syngnathidae, which have been increasingly threatened by anthropogenic activities. We describe the diet composition and feeding strategy of southern pipefish Syngnathus folletti inhabiting a Widgeon grass (Ruppia maritima L.) bed in the estuarine zone of Patos Lagoon, southern Brazil. We also investigated whether mouth gape affected the size of prey items consumed and based on indirect evidence, we suggest possible pipefish foraging movements within the bed. Individuals were collected from December 1994 to March 1995 in a Ruppia maritima bed located in the Patos Lagoon Estuary during day and night periods. We analyzed the stomach contents of 108 individuals (54 females and 54 males). Both...
