Application of<scp>AIS</scp>? and flyover?based methods to monitor illegal and legal fishing in Canada's Pacific marine conservation areas

چکیده
New approaches are required to undertake the substantial task of monitoring ongoing fishing activity in marine conservation areas ensure goals achieved. To address this need, we applied previously developed, yet currently underused, vessel tracking methods based on Automatic Identification System (AIS) and aerial surveillance (“flyovers”) Canada's Pacific from 2012 2019. We used satellite terrestrial-based AIS receivers flyover-based visual observations estimate illegal legal after 185 area (CA) enactments (i.e., static, geographically defined with regulations). compared effectiveness detecting between AIS- methods, latter determine that 93% vessels were actively CAs without AIS. The AIS-based method still detected 3303 h enactment, both estimated 22%–24% was illegal. application these also shed light complexity regulations across varying CA-specific restrictions). This highlighted need better align gear classifications CA regulation specifications, conversely simplify (e.g., no-take), for more accurate evaluation moving forward.

Presumably, this is due to poor local enforcement coupled with the growing international demand (and high economic incentives) for shark and other wildlife products. Understanding illegal shark fishing p...

—Molecular tools and analyses have played pivotal roles in uncovering the processes and patterns of biodiversity in the Indian and Pacific oceans. However, integrating genetic results into management and conservation objectives has been challenging, with few examples that show practical applicability. This review aims to address some of the perceived barriers to an enhanced approach that integr...
