VORWERK, P.D.; FRONEMAN, P.W. and PATERSON, A.W.. Recovery of the critically endangered river pipefish, Syngnathus watermeyeri, in the Kariega Estuary, Eastern Cape province. S. Afr. j. sci. [online]. 2007, vol.103, n.5-6, pp. 199-201. ISSN 1996-7489.
An intensive ichthyofaunal SURVEY IN the permanently open Kariega Estuary along the Eastern Cape coast has identified a breeding population of the critically endangered river pipefish, Syngnathus watermeyeri, within the middle and upper reaches of the system. This is the first recorded capture of this species in the estuary for over four decades. We suggest that the presence of S. watermeyeri is the result of the heavy rainfall within the region, which contributed to the establishment of optimum habitat requirements (mesohaline conditions and increased food availability) of the pipefish.
