| As a result of the introduction of the Landing Obligation in European fisheries there is a need to equip industry with the tools and knowledge to avoid unwanted catches. Optimising fishing practices in terms of time and location fished have been acknowledged as being important in modulating catch composition. Mapping techniques used to identify and manage the spatio-temporal nature of bycatch, however, remain underutilized. Data collected on board commercial fishing vessels by observers provides an important source of information on the component of catches discarded. Using a unique dataset, combining observer data for Irish, French and British vessels operating in the Celtic Sea between 2010 and 2015, maps were developed to identify where catches of quota... |

| The paper presents a complex framework to analyse spatially and seasonally heterogenous fisheries. Typologies based on multivariate analysis have been applied on multi-species fisheries to identify patterns in fishing effort and subsequent impacts on various species. Although the Tasmanian rock lobster fishery is a single species fishery, it displays highly variable spatial and seasonal patterns of fishing effort. Rock lobster is a stationary species, so the stock of rock lobster is heterogeneously distributed along the Tasmanian coast depending on local removal from catch. The various perturbations undergone by the stock for the past decade, (overexploitation, introduction of individual transferable quotas (ITQs), climate change) led to the reorganisation... |
