“…Several cultivable invertebrate species have shown signs of vulnerability to the changing environmental conditions (Ahmed & Diana, 2015;Dworjanyn & Byrne, 2018;Steeves et al, 2018). One of the proposed measures to mitigate the negative effects of climate change in the aquaculture industry is the search for new and better adapted species (D'Abramo & Slater, 2019). Members of the mud clam genus Geloina (Polymesoda) have been reported to be resilient to adverse environmental conditions (Morton, 1976;Gimin et al, 2004;Argente et al, 2014).…”

The status of the mud clam, Geloina expansa, an important bivalve in the artisanal fisheries of the Loay-Loboc River, was assessed using monthly shell length frequency data (October, 2012 to January, 2015 to estimate population parameters. Growth parameters derived were L ∞ = 91.35 mm, K = 0.75 yr -1 and t 0 = -0.16. Predicted L max was 90.39 mm. Estimated growth rates showed fast growth for the first two years. Longevity is approximately 6.1 years. Length-weight relationship showed a positive allometric growth (r 2 = 0.94). The estimated total mortality (Z) was 2.89 yr -1 . Natural (M) and fishing (F) mortalities estimates were 0.90 yr -1 and 1.99 yr -1 , respectively. Estimated exploitation rate (E = 0.69) was higher than the maximum sustainable exploitation (E max = 0.41). Two annual recruitment peaks occurred during the months of December to February and July to August. Monthly condition index (CI) suggested that spawning is year-round. It appeared that the variations in CI of G. expansa in the river was influenced by the water temperature and salinity (r² = 0.54; P < 0.0001). These biological information may be used for aquaculture technique development for G. expansa in central Philippines which will aid in the conservation and management of natural stocks.

“…Considering current problems like climate change, population growth, urbanization as well as overexploitation and pollution of natural resources ‘global food production is the largest pressure caused by humans on Earth, threatening local ecosystems and the stability of the Earth system’ (Willett et al, 2019). Consequently, there is an urgent need to find solutions for sustainable and efficient food production solutions to cope with the consequences of these issues (D'Abramo & Slater, 2019).…”

This case study examined the productivity and economic performance of a double recirculation aquaponic system in Germany with a total interior area of about 540 m2. Calculations were carried out as an ex post analysis based on one‐year production data. The initial situation was not profitable; therefore, two scenarios were developed, which envisaged a significantly improved productivity of the fish as well as of the plant unit and a more than threefold enlargement of the greenhouse to make maximum use of the fish effluent. An ex ante analysis was performed and showed that the second scenario was profitable with a payback period of about 12 years. On the basis of this scenario, a simple but comprehensive model case with the complete set of economic key indicators showed that aquaponics is feasible if it exploits its potential, regardless of the high initial investment costs. The model case would cover an overall space of about 2,000 m2, which is suitable for professional aquaponics in urban and peri‐urban areas with their limited space availability. Furthermore, multi‐loop aquaponics with its inherent circles fits into the circular city concept and implements resource‐efficient and sustainable food production into the urban fabric, which is important with increasing urbanization.

“…Few strategies are currently available to mitigate climate change impacts on fish arising from extreme low and high‐temperature events (Table 7). It is essential to find ways to improve fish physiological fitness where water temperatures fluctuate largely (D'Abramo & Slater, 2019; Islam, Kunzmann, Henjes, & Slater, 2021). Temperature control could be an option to keep fish healthy during extreme temperature events, which is only possible in highly controlled aquaculture systems.…”

“…Further increases in extreme temperature events will amplify water quality fluctuation and hydrological stress (Albouy, Guilhaumon, Araújo, Mouillot, & Leprieur, 2012; Kharin, Zwiers, Zhang, & Wehner, 2013; Nowicki et al, 2019) to resident organisms. Shifts in ambient temperatures alter the overall fitness and performance of ectothermic fish with stark implications for global aquaculture (D'Abramo & Slater, 2019; Gaylord, MacKenzie, & Gatlin, 2001; Small & Peterson, 2005; Small, Soares, Woods, & Dahl, 2002). Fluctuations in temperature affect many aspects of physiology in fish, including feed intake, survival, growth, reproduction, behavior, distribution, energy acquisition, and physical properties of biomolecules (Chang et al, 2018; Islam, Kunzmann, Henjes, & Slater, 2021; Makrinos & Bowden, 2016; Maulvault et al, 2017; Wong, Walsh, & Morris, 2018).…”

Climate change‐induced extreme temperature events are becoming more intense and frequent. For fish, temperature is the master abiotic factor that controls and limits fish development and physiology at all stages of aquaculture. Major physiological constraints at the individual level underpin changes in fish growth, hemato‐physiology, metabolism, immune and molecular stress responses to extreme temperature events. Extreme temperature impacts on fish vary among and within the diverse species depending on stress magnitude and associated factors. This review synthesizes the impacts of climate change‐induced extreme temperature events on neuroendocrine, oxidative, metabolic, osmotic, molecular, hemato‐biochemical, and immune responses in fish related to aquaculture. Besides, overall aspects of extreme temperature impacts on fish growth and reproduction are also discussed. Possible mitigation measures to maintain the fish's physiological fitness during extreme temperature events are also addressed. However, studies on the interactive effects of extreme temperature events with other associated environmental stressors are needed across a broader range of species to gain a better understanding of fish response and aquaculture performance during extreme temperature events. Moreover, for fish, studies on alternative species, development of stress‐tolerant strains, and the possibilities of nutritional mitigation measures as a potential option to combat extreme temperature stress are promising and should be pursued in future studies.
