Description
Temporal abundance data and stomach analysis for two gobies, Asterropteryx semipunctatus and Gnatholepis sp.1, caught in Gazi Bay between July and October 1995. The data were digitized by VLIZ from the original report: Ndede, R.O. (1998). Temporal patterns in the density and feeding ecology of gobies, Asterropteryx semipunctatus and Gnatholepis sp.1 in East African mangrove ecosystem (Gazi Bay, Kenya). MSc Thesis. KUL: Brussel. VIII, 97 pp. more

To understand the 24 hrs (temporal) pattern in the density distribution and the consumption of prey items (food) for Asterropteryx semipunctatus and Gnatholepis sp.1, an investigation was carried out in the sub-tidal Western creek of Gazi Bay (Kenya) between July and October 1995. In order to investigate a semi-lunar pattern, ten twenty four hour cycles were sampled at consecutive spring and neap tides. A total of 480 (10 sampling x 12 sampling times x 4 locations) cases were collected. Two hours samplings consisted of 4 hauls with duration of 10 minutes and mean distance of 300m.
