“…Climate change impacts are witnessed in various aspects of human life and living organisms around the globe, in which fisheries are widely recognized to be affected [ 4 – 7 ]. Climate change directly disturbs aqua species’ growth, reproduction, migration behavior, and distribution, as it induces fluctuations in physical, chemical, and biological factors [ 8 – 12 ]. Indirect impacts via ecosystems include changes in food abundance, competitors, predators, and pathogens [ 13 – 16 ].…”

Fisheries are forecasted to shrink in the tropics due to climate change. In Vietnam, fisheries are a pro-poor economic sector and essential nutrition source; however, welfares of producers and consumers in the climate change context are not well understood. While most studies focus on the gains or losses of total products and revenues, this paper pays additional attention to the changes in surpluses of market players in the long run. A combination of the production function, demand and supply functions, and partial equilibrium analysis is employed to measure the production and welfare impacts based on time series data from 1976 to 2018 and a Vietnam household living standards survey in 2018. The results show that relative to the present, catch yield is likely to reduce 35%-45% by mid-century and 45%-80% by the end of the century. Consumers may lose their surplus of 7-9 billion USD (PPP, 2018) by 2035 and 10-18 billion USD by 2065 due to supply reduction, while producers may gain additional profit of 3.5-4.5 billion USD by 2035 and 5-9 billion USD by 2065 owing to a price increase. The research findings suggest that Vietnam could impose measures to limit capture effort, as set out in the Law of Fisheries 2017, without harming fisher welfare. The expansion of aquaculture could reduce the gap between supply and demand of wild fish to mitigate consumer welfare loss; however, this impact is still ambiguous.

“…Similarly, the number of responses for anadromous marine species was limited (npopulations = 14, mostly Oncorhynchus spp. (n = 8); Fredston-Hermann et al, 2021;Mueter et al, 2006;Nye et al, 2009;Yasumiishi et al, 2020), yielding an LRS estimate close to marine exclusive species responses (Fig. 6B).…”

“…Whilst significant response variation is likely explained by a multitude of climatic and biotic factors (McHenry et al 2019), the majority of reviewed studies investigated only temperature as a predictor (in some cases only by suggestion rather than empirical testing). For example, some studies suggest that range shifts may be driven by abundance changes, as density dependence may lead to range expansions during high abundance and vice versa (Kotwicki et al, 2013;Olafsdottir et al, 2019;Swain et al, 2006;Worm and Tittensor 2011;Yasumiishi et al, 2020). Nevertheless, it is still unknown how marine range shift estimates from single-predictor studies compare to multi-factor estimates.…”

The current effects of global warming on marine ecosystems are predicted to increase, with species responding by changing their spatial distributions. Marine ectotherms such as fish experience elevated distribution shifts, as temperature plays a key role in physiological functions and delineating population ranges through thermal constraints. Distributional response predictions necessary for population management have been complicated by high heterogeneity in magnitude and direction of movements, which may be explained by both biological as well as methodological study differences. To date, however, there has been no comprehensive synthesis of the interacting ecological factors influencing fish distributions in response to climate change and the confounding methodological factors that can affect their estimation. In this study we analyzed published studies meeting criteria of reporting range shift responses to global warming in 115 taxa spanning all major oceanic regions, totaling 569 three-dimensional population responses (latitudinal, longitudinal and depth), with temperature identified as a significant driver. Overall, studies on marine fish distributional responses have generally been of limited spatial and temporal scope, with comparisons among studies being complicated by large variation in methodology. We identified varying degrees of heterogeneity in latitudinal range shifts (km year-1) across ecological and methodological predictors, with multivariate regression analysis revealing response rate differences due to niche affinity, depth changes, as well as methodological biases due to different approaches in estimating and reporting latitudinal range shifts. Finally, we found strong geographical publication bias and limited taxonomical scope, highlighting the need for more representative and standardized research in order to address heterogeneity in distribution responses and improve predictions in face of changing climate.

“…How do factors such as interannual variability, climate change, fisheries and habitat loss affect prey availability? Climate change, which is rapid in some regions, is predicted to have considerable impacts on the distribution, biomass, energy density and body size of prey species ( Flores et al, 2012 ; Yasumiishi et al, 2020 ; Florko et al, 2021 ). Such changes have clear bioenergetic implications for marine mammals and the ecosystems they inhabit ( Costa, 2008 ; Laidre et al, 2020 ; Gallagher et al, 2022 ).…”

Bioenergetic approaches are increasingly used to understand how marine mammal populations could be affected by a changing and disturbed aquatic environment. There remain considerable gaps in our knowledge of marine mammal bioenergetics, which hinder the application of bioenergetic studies to inform policy decisions. We conducted a priority-setting exercise to identify high-priority unanswered questions in marine mammal bioenergetics, with an emphasis on questions relevant to conservation and management. Electronic communication and a virtual workshop were used to solicit and collate potential research questions from the marine mammal bioenergetic community. From a final list of 39 questions, 11 were identified as ‘key’ questions because they received votes from at least 50% of survey participants. Key questions included those related to energy intake (prey landscapes, exposure to human activities) and expenditure (field metabolic rate, exposure to human activities, lactation, time-activity budgets), energy allocation priorities, metrics of body condition and relationships with survival and reproductive success and extrapolation of data from one species to another. Existing tools to address key questions include labelled water, animal-borne sensors, mark-resight data from long-term research programs, environmental DNA and unmanned vehicles. Further validation of existing approaches and development of new methodologies are needed to comprehensively address some key questions, particularly for cetaceans. The identification of these key questions can provide a guiding framework to set research priorities, which ultimately may yield more accurate information to inform policies and better conserve marine mammal populations.
