Description Large scale fluctuations of anchovy catch are observed across Indian coast and an understanding of the complex interactions of climato-oceanic and biological factors of fishes is essential to realize the cause of such catch variations. Therefore, the trend of sea surface temperature anomaly in the context of the spatial and temporal aspects of anchovy (Stolephorus spp.) fisheries along southwest coast of India were investigated. The coast was classified into three strata; first (ST_1, 8° to 10.2° N), second (ST_2, 10.2° to 13° N) and third (ST_3, 13° to 16° N) to study the spatial variation. Similarly, seasonality was studied by considering three seasons in a year as pre-monsoon (February-May, PRM), monsoon (June-September, MON) and post-monsoon (October-January, POM). The catch (kg) per unit effort (hour) for the all gears operated was also analyzed to observe the distribution of Stolephorus spp. The impact of climate change on Stolephorus fisheries was evident in both vertical and horizontal shifting of the catch.
