“…Japan is also located near the fastest warming marine waters; the 1976/1977 and 1987/1988 regime shifts significantly influenced the ecosystem of the Tsushima Warm Current (TWC) in the Japan/East Sea [11][12][13]. Warm-water large predatory fish and cold-water demersal species showed opposite responses to the changes in water temperature in the TWC region, indicating the significant impact of oceanic conditions on fishery production [13].…”

“…Warm-water large predatory fish and cold-water demersal species showed opposite responses to the changes in water temperature in the TWC region, indicating the significant impact of oceanic conditions on fishery production [13]. Regime shifts also occurred in Korean waters in 1976 and 1988 [25,26], as well as in the Kuroshio waters in 1987/1988 [11].…”

“…The increase in SST has been accompanied by a shift in ocean currents. However, the mechanisms behind these changes are the decline of the CCC and the enhancement of the KC [6,[11][12][13]. The ocean environment changes contribute to modifications in the productivity, distribution, and phenology of marine species, affecting ecosystem processes and altering food webs [5,6,[14][15][16].…”

Abstract:In this study, we analyzed the fish species composition data of coastal capture fisheries in Taiwan between 1963 and 2010. The purpose of the analysis was to understand the long-term changes in marine ecosystems. A ratio-to-moving average method was used in conjunction with adjusted seasonal indices to determine the seasonality of individual catch items and to examine the trends shown by the species with the same seasonality. Over the 48-year timespan of the data, 31 species, i.e., 64% of the total number of species, were identified as seasonal migrants. The catch ratio for species showing a single peak in the spring increased steadily over time; however, those species with a single peak in the winter decreased. The catch ratio for those species with dual peaks in both summer and fall varied greatly before 1978. Increasing trends began in the 1980s and accelerated until 1998. As a result of this increase, the previous concentration of the fishing season in the winter months became highly diffuse. Additionally, the winter and/or spring species continued to decrease year after year as the summer and/or autumn species gradually came to dominate the catch. This change in fishing seasonality is likely not an anthropogenic effect. However, the change coincides with trends in sea surface temperature fluctuations. Such variation may not only cause structural change in marine ecosystems but can also significantly impact the economy and the livelihoods of those associated with the fishing trade.

“…This change to a lower trophic level might have been transferred to upper trophic levels because the abundances of fishes also exhibited similar decadal variability (Tian et al ., 2006, ). A more recent study found that different patterns of abundance fluctuated between the cold‐ and warm‐water species during the regime shift in the late 1980s (Tian et al ., ), which indicates the importance of the geographical affinity of fishes in response to environmental forcing. However, most of these studies only focused on changes in abundance.…”

“…An important question that emerges from these studies is why the responses of species to climate variability can vary greatly (Chen et al ., ), even within the same ecosystem (Hsieh et al ., , ; Perry et al ., ; Tian et al ., , ; Nye et al ., ). To answer this question, ecologists have investigated variations in the life history and ecological traits of species.…”

In the present study, we examined the effects of climate on temporal variation in the abundance and geographical distribution of demersal fishes at both interannual and decadal scales in the Tsushima Warm Current region of the Japan Sea using single-trawler fishery data . This single-trawler fishery targeted multiple species with different geographical affinities and life history traits. Thus, these data were suitable for examining the biological mechanisms that underlie how species respond to climate variability. Our results indicate that the distributional changes of species in response to decadal climate variability are best explained by asymptotic length, which indicates that warming has greater negative effects on larger fishes in the Japan Sea. However, none of the variables examined (including geographical affinity, asymptotic length and age at maturation) could explain the shift in abundance at interannual or decadal scales. It should be noted that life history traits and geographical affinities only provide partial explanations of the responses of species to environmental variability, thereby suggesting that other factors, such as interactions among species, may be involved in mediating species responses.
