    Claim by Pichegru et al. that marine no-take zone benefits penguins remains premature
    (2010) Butterworth, Douglas; Brandao, Anabela; de Moor, Carryn; Robinson, William
    Pichegru et al. (2010), and a follow up comment by Ryan et al. (2010), make strongly stated claims that closures to pelagic fishing around islands with penguin breeding colonies lead to rapid improvements in those penguin populations. These claims are contested for a variety of reasons, including problems with the analysis method used. Claims that the pelagic fishing stocks are in poor condition, and that this is because of an absence of spatial management, are also contested, as are some other sweeping statements. The data currently available are too limited to be able to confirm or deny the claims made at this stage.
