Climate change is altering environmental conditions in the Patagonia ecosystems, with potential consequences for the distribution of marine species that sustain artisanal fisheries within the inner sea of northern Chilean Patagonia (41°28.6′S–45°30′S). We evaluated current and future habitat suitability for one forage species (Falkland sprat, Sprattus fuegensis ) and three demersal predators ( Macruronus magellanicus , Merlucc...

The Antarctic krill ( Euphausia superba ) fishery is primarily concentrated around the major island groups and shelf‐break regions of the West Antarctic Peninsula and South Orkney Islands. Climate‐induced sea ice retreat has recently expanded fishing access to previously inaccessible areas, thereby altering spatial and temporal patterns of fishing activity. Because krill distribution and aggregability strongly influence where...

The abundance of juvenile fish changes due to endogenous processes, and determining the functional relationships among conspecifics is essential for fisheries’ management. The hake (Merluccius gayi) is an overexploited demersal fish widely distributed in Chile, from 23°39′ S to 47°00′ S in shallow and deep water over the continental shelf and shelf break. We studied the spatiotemporal distribution of hake juveniles (from ages...

River runoff to the coastal zone is one of the most important environmental variables that influences the structure and functioning of the neritic trophic web and modulates temporal fluctuations of coastal fishery production in many ecosystems worldwide. The relationship between recruitment of anchovy ( Engraulis ringens ) and common sardine ( Strangomera bentincki ) in central-south Chile (34°–40°S) and fluctuations in river...

Marine biota are redistributing at a rapid pace in response to climate change and shifting seascapes. While changes in fish populations and community structure threaten the sustainability of fisheries, our capacity to adapt by tracking and projecting marine species remains a challenge due to data discontinuities in biological observations, lack of data availability, and mismatch between data and real species distributions. To...

Off southern‐central Chile, the impact of spring upwelling variability on common sardine ( Strangomera bentincki ) recruitment was examined by analyzing satellite and coastal station winds, satellite chlorophyll, and common sardine recruitment from a stock assessment model. In austral spring, the intensity of wind‐driven upwelling is related to sea surface temperature (SST) from the Niño 3.4 region, being weak during warm peri...
