| Abstract | The West Coast Demersal Biomass Survey on the Africana Voyage 127 took place between 6 January and 3 February 1995. The survey collected bottom trawl catches and hydrological data, including CTD profiles, to estimate the abundance of hake and other demersal species off the west coast of South Africa. Deep-water trawls up to 1200m were conducted between the Orange River and Cape Agulhas. The cruise also included intercalibration trawling with the Norwegian research vessel Dr Fridtjof Nansen. |
| Methods | Demersal biomass sampling was conducted using bottom trawl gear across the west coast of South Africa from the Orange River to Cape Agulhas. Deep-water trawls reaching depths of up to 1200m were used to assess hake and other demersal fish populations. Hydrographic measurements were collected using CTD profiles. The cruise also included intercalibration trawling exercises with the Norwegian research vessel Dr Fridtjof Nansen to ensure consistency in trawl survey methods. |
