Aspects of the biology and population dynamics of the deep-water commercially exploited crabs off South West Africa/Namibia
… trawling, effective fishing area and tag-recapture) have been used to examine the abundance and density of red crab off Namibia, and are critically compared . Research on the stone crab has been largely restricted to an analysis of commercial catch data, though an unusual symbiotic …

Using mark-recapture methods to estimate population size and survival of pyjama sharks (Poroderma africanum) in Mossel Bay, South Africa
… result of their biological characteristics. Markrecapture models were applied to conventional tag recapture data and acoustic telemetry data to estimate abundance, apparent survival, recapture probability and temporary emigration for the pyjama shark, Poroderma africanum in Mossel Bay, South …

Birth, death and taxis: North Atlantic right whales in the twenty-first century
… by age, habitat-use pattern and individual. Tag-recapture models of extremely small populations are vulnerable to such heterogeneity, since animals missing for extended periods can create spurious estimates of survivorship, growth rates, and population viability.</p><p>An analysis of …

An intensive study of movement and population dynamics in Triakis megalopterus in the De Hoop Marine Protected Area, South Africa
… excellent opportunity for this assessment. Mark-recapture data of 924 T. megalopterus caught at two sites in the De Hoop MPA from 1996 to 2020, a no-take reserve, were used to estimate home range size and natural mortality rates. Displacement frequencies were modelled to estimate home range size …

The spatial ecology and behaviour of the broadnose sevengill shark (Notorynchus cepedianus) in South Africa
… Research Institute's Cooperative Fish Tagging Project. Broad-scale patterns in coastal presence, movement and population connectivity were then investigated for both sexes and a range of sizes of N. cepedianus in South Africa using acoustic telemetry, and a national scale array of …
