Abstract


  • Few regions on earth remain untouched by fishing activity. As such, effective longterm

    no-take marine reserves (NTMRs) and other area-based management systems

    that restrict fishing serve as vital reference areas for assessing the magnitude and

    recovery potential of marine ecosystems from human influence over both space and

    time. Much of the peer-reviewed literature and meta-analyses demonstrate variable

    but overall positive responses to such protection for fish and some other taxa. These

    include significant increase of stock species abundance and biomass within boundaries,

    cross-boundary spill-over of adults and larvae, and increased egg production. A

    reserve may meet its biodiversity objectives and contribute to fished stocks, however,

    determining the extent of that contribution depends on several factors. These factors

    include: understanding and monitoring the species biology, and the effectiveness of

    and compliance with management, and changes in fishing pressure external to the

    NTMR or other type of spatially-managed area from which some fishing activities

    are excluded. This presents significant data and cost challenges of scope, scale and

    monitoring method for assessment of NTMRs and fishery management throughout

    the, often extensive, range of the stock. The situation is one in which proof is hard to

    establish and absence of proof of effect is not proof of absence of effect (the issue of

    Type I and Type II errors in experimental design).
