9.3 Results
9.3.1 Description of inter annual trends in fish species diversity
For the first time, the 2011 annual survey recorded Cape Stumpnose in Big Bay and Langebaan
lagoon samples. This species is rare on the west coast and typically inhabits south and east coast
estuary nursery habitats. Although Cape Stumpnose had not been sampled during any of the earlier
annual seine net surveys, this species was caught in the monthly surveys conducted during 2007-
2008 by Clement Arendse. The total species count remains at thirty-seven fish species taking into
account the three different species of goby of the genus Caffrogobius, namely: C. nudiceps, C.
gilchristi and C. caffer that have been identified in the Bay. Due to the uncertainty surrounding
identification of these species in earlier surveys, they have been grouped at the generic level for data
