| Summary | The seasonal and diel feeding pattern of spot (Leiostomus xanthurus), Atlantic croaker (Micropogonias undulatue), southern flounder (Paratidhthys lethostigma), and bay anchovy (Anchoa mitchilli) were examined during their residence in the midreaches of Bond Creek. Stomach analysis in addition to estimates of the abundance of zooplankton and benthos indicated that spot and Atlantic croaker are opportunistic feeders. The items most often found in the stomachs were usually those items exhibiting a seasonal peak in abundance. Southern flounder however, extensively utilized mysids regardless of the season and exhibited a secondary piscivorous feeding habit. Bay anchovy were found to be zooplanktivores utilizing larger zooplankton with increasing size. Little diel difference was seen in the type of prey consumed. Benthos however, were consumed more frequently at night by spot in early spring and late summer and in early summer by Atlantic croaker. Diet breadths were widest in spot and Atlantic croaker and narrowest in southern flounder and bay anchovy. Diet overlap values were high for all six combinations. Mysids were the most selected prey using Ivlev's electivity index while calanoid copepods were the most avoided prey. Food source was not limited in Bond Creek during the study period consequently the four species occupied similar niches within Bond Creek. |
