Special Issue Information

Dear Colleagues,

Global change has been a topic of concern in recent decades. Oceans act as a buffer against climate change and global warming, but at the expense of the stability of the climate system and marine ecology. Changes such as sea level and circulation changes, melting ice shelves, ocean acidification and hypoxia, and food chain collapse either directly or indirectly affect marine fisheries and marine ecosystems on a global scale, on which, in addition, other synergistic driving forces related to human activity and its impacts act, such as invasive alien species, pollution, habitat use and overexploitation of resources.

In this situation, in order to apply effective measures to maintain fishery production and ecological balance, it is necessary to approach the problem from a holistic point of view. It is urgent to fill the gaps in scientific knowledge, implement new research methods, and retrieve longer historical series on the variability of populations, ecosystems, and the marine environment to achieve sustainable ecological and economic solutions.

This Special Issue aims to provide an overview of the state of the art of fisheries, aquaculture and marine ecosystem adaptation on global change. This includes new or existing methods applicable to fisheries, stock-specific examples of applications from data to advice, and reviews of historical information that provide guidance to scientists to address the challenges in future data collection and management advice provision.

This study investigates the impacts of climate variability, particularly La Niña events, on the fish community on the continental shelf of the northern South China Sea, a region highly sensitive to environmental fluctuations. Historical fishery survey data, collected from autumn 2019 to autumn 2022, were used to analyze changes in species composition, diversity indices, and community structure during La Niña and non-La Niña periods. The results show that La Niña significantly altered the fish community dynamics. During La Niña, cold-water conditions expanded the range of suitable habitats for cold-water species, leading to increased dominance of the Japanese scad (Decapterus maruadsi), with its index of relative importance (IRI) reaching 1795.9 and 1320.2 in autumn 2021 and 2022, respectively. In contrast, warm-water species experienced a reduction in suitable habitats. During La Niña, Margalef’s richness index (D’) peaked at 23.18 in autumn 2021 but decreased to 20.69 by spring 2022. The Shannon–Wiener diversity index (H’) dropped from 2.597 during a non-La Niña period (spring 2020) to 2.406 during La Niña (spring 2022); similarly, Pielou’s evenness index fell from 0.4749 to 0.4396, indicating an increase in ecological imbalance. As La Niña conditions weakened, the fish community began to recover. By autumn 2022, D’ had risen to 22.73 and H’ to 2.573, reflecting a gradual return to fish community conditions before the La Niña event. Species distribution models incorporating key environmental variables (i.e., sea surface temperature, salinity, and dissolved oxygen) demonstrated that the habitat of D. maruadsi expanded significantly during La Niña and contracted during post-event periods. Our findings highlight the ecological sensitivity of fish communities to climate variability and underscore the importance of adaptive resource management strategies to mitigate the impacts of climate change on marine ecosystems. This research provides valuable insights for sustaining regional fishery resources under changing environmental conditions. Full article

The top shell, Turbo sazae, occurs commonly in the shallow rocky subtidal area of Jeju Island off the south coast of Korea, and it is one of the most valuable gastropod resources supporting the local shellfish industry. T. sazae landings in Jeju have declined dramatically in recent years, although the factors involved in this decline are yet to be identified. Recent studies also have reported that T. sazae is expanding its distribution range to the east coast of Korea, possibly due to the increasing seawater temperature. In this study, we investigated the hemocyte responses of T. sazae to elevated seawater temperatures in order to gain a better understanding of its immunological response to higher water temperatures. In this experiment, we exposed top shells to a gradual increase in seawater temperature, ranging from 22 °C to 30 °C, over a span of 9 days. We employed flow cytometry to assess various cellular immune responses, including hemocyte viability, phagocytosis capacity, and the production of reactive oxygen species (ROS) in T. sazae. The results showed that top shells exposed to elevated seawater temperature exhibited a significant decrease in phagocytosis capacity and an increase in ROS production after 3 days of the experiment. These findings indicate that an elevated seawater temperature imposes a stressful condition on T. sazae, characterized by reduced phagocytosis capacity and increased oxidative stress. Full article

Marine environmental variability and climate change are interconnected; they are the main causes of the fluctuations in ecosystems and cyclically affect fisheries. This work has four main goals. The first is to present a broad historical review of international research activities on fisheries and climate change, mainly in European waters. We have recovered a selection of seminal international scientific publications from 1914 to 1995, which aroused great interest among the scientific community at that time, although most of these publications have fallen into oblivion in the 21st century. The second goal is to review the main intergovernmental initiatives on climate and marine research from the 1980s to the present, detecting gaps and a lack of unanimity in some guidelines from international organizations. The third goal is to analyze decadal warming/cooling in the Canary Current Upwelling System (extending from the NW Iberian Peninsula to Senegal), to understand the current rapid tropicalization of pelagic and benthic ecosystems in Southern European Atlantic seas. The fourth goal is to identify priority research lines for the future, including the need to promote an international retrospective on fisheries oceanography research, for at least the last hundred years.
