title: Atlantic Ocean marlin fishery and climatic oscillations dataset

description: Climatic oscillations affect fish population dynamics, ecological
 processes, and fishing operations in maritime habitats. This study
 examined how climatic oscillations affect catch rates for striped, blue,
 and silver marlins in the Atlantic Ocean. These oscillations are regarded
 as the primary factor influencing the abundance and accessibility of
 specific resources utilized by fishers. Logbook data were obtained from
 Taiwanese large-scale fishing vessels for climatic oscillations during the
 period 2005–2016. The results indicated that the effect of the Subtropical
 Indian Ocean Dipole on marlin catch rates did not have a lag, whereas
 those of the North Atlantic Oscillation, Atlantic Multidecadal
 Oscillation, Pacific Decadal Oscillation, and Indian Ocean Dipole had
 various lags. Pearson’s correlation analysis was conducted to examine the
 correlations between atmospheric oscillation indices and marlin catch
 rates, and wavelet analysis was employed to describe the influences of the
 most relevant lags. The results indicated that annual atmospheric
 fluctuations and their lags affected the abundance and catchability of
 striped, blue, and silver marlins in the study region. This, in turn, may
 affect the presence of these species in the market and lead to
 fluctuations in their prices in accordance with supply and demand.
 Overall, understanding the effects of climatic oscillations on fish
 species are essential for policymakers and coastal communities seeking to
 manage marine resources, predict changes in marine ecosystems, and
 establish appropriate methods for controlling the effects of climate
 variability.
