  abstract = {{M}acrozooplankton plays a key role in pelagic ecosystems as a link between lower trophic levels and fish. {H}owever, although its ecological role is usually considered in polar ecosystems, it is rarely considered in temperate ones. {T}o obtain comprehensive information on the macrozooplankton distribution in the {B}ay of {B}iscay we adapted a bi-frequency acoustic method developed for the {H}umboldt {C}urrent system. {T}his method can be used to extract continuous and simultaneous high-resolution information on the spatiotemporal patterns of biomass distributions of macrozooplankton and pelagic fish throughout the diel cycle. {T}he 2 distributions were mapped using geostatistical techniques. {W}e applied kriging with external drifts, which accounts for both diel and across-shore changes in macrozooplankton biomass. {W}e then used a cross-variogram to determine the scale-dependent relationships between macrozooplankton and fish. {T}he results show how macrozooplankton and fish are distributed according to the different ecological domains (coast, shelf, shelf-break and offshore) along the {S}panish and {F}rench coasts. {S}pecific macrozooplankton hotspots were observed, but macrozooplankton was generally more abundant offshore than inshore, whereas fish showed the opposite trend. {T}his pattern was confirmed by the aggregation sizes, which increased towards oceanic waters for macrozooplankton and decreased for fish. {F}inally, the correlation between fish and macrozooplankton was positive on a small scale (<30 nautical miles) and negative on a large scale (>30 nautical miles).},
