“…Earlier studies also reported the positive impact of temperature on somatic growth ( Brander, 1995 ; Heather et al, 2018 ; Gamperl et al, 2019 ; Huangab et al, 2021 ). This may be due to the increased production of benthos and plankton ( Thackeray et al, 2013 ; Tao et al, 2015 ), which indirectly influenced the energy intake and growth of the studied fish ( Pörtner & Farrell, 2008 ; Prokešová et al, 2020 ). The pH, DO, and silicate ( Viadero, 2005 ; Bajaj, 2017 ; Zhang et al, 2017 ) favors the production of diatoms and algal matter in water, which forms the primary food of M. cephalus ( Lavanya et al, 2018 ).…”

Fish stocks that are grown under diverse environmental conditions have different biometric relationships and growth patterns. The biometric length-weight relationship (LWR) is an essential fishery assessment tool, as fish growth is continuous and depends on genetic and environmental factors. The present study attempts to understand the LWR of the flathead grey mullet, Mugil cephalus Linnaeus, 1758, from different locations. The study area encompassed its distribution in the wild across freshwater location (one), coastal habitats (eight locations), and estuaries (six locations) in India to determine the relationship between various environmental parameters. Specimens (n = 476) of M. cephalus were collected from commercial catches and the length and weight of individual specimens were recorded. Monthly data from the study locations were extracted for nine environmental variables from the datasets downloaded from the Physical Oceanography Distributed Active Archive Center (PO.DAAC) and the Copernicus Marine Environment Monitoring Service (CMEMS) over 16 years (2002 to 2017) on the Geographical Information System platform. The parameters of the LWR, intercept ‘a’ and slope or regression coefficient ‘b’, varied from 0.005321 to 0.22182 and 2.235 to 3.173, respectively. The condition factor ranged from 0.92 to 1.41. The partial least squares (PLS) score scatter plot matrix indicated differences in the environmental variables between the locations. PLS analysis of the regression coefficient and environment parameters revealed that certain environment variables viz., sea surface temperature, salinity, dissolved oxygen, nitrate, and phosphate, played a positive role. However, chlorophyll, pH, silicate, and iron played a negative role in influencing weight growth across various locations. The results revealed that the M. cephalus specimens from three locations, Mandapam, Karwar, and Ratnagiri, possessed significantly higher fitness to their environment than those from the other six locations. The PLS model can be used to predict weight growth under the various environmental conditions of different ecosystems. The three identified locations are useful sites for the mariculture of this species considering their growth performance, the environmental variables, and their interactions. The results of this study will improve the management and conservation of exploited stocks in regions affected by climate change. Our results will also aid in making environment clearance decisions for coastal development projects and will improve the efficiency of mariculture systems.

Fish and hyperoxia—From cardiorespiratory and biochemical adjustments to aquaculture and ecophysiology implications

Hyperoxia occurs when water oxygen (O2) levels exceed normal atmospheric pressure (i.e., >100% air saturation). Fish can experience hyperoxia in shallow environments due to photosynthesis or in aquaculture through O2 supplementation. This review provides a comprehensive synthesis of the effects of hyperoxia on fish, spanning influences on cardiorespiratory function, acid‐base balance, oxidative stress and whole animal performance (e.g., thermal tolerance and growth). Fish hypoventilate in hyperoxia, but arterial and venous blood oxygenation increases in spite of reduced convection. Persistently high levels of blood oxygenation in hyperoxia do not commonly result in reduced blood O2 carrying capacity, but assessments in undisturbed fish are required to clarify this. Hypoventilation also causes the retention of carbon dioxide, hence respiratory acidosis. Another consequence of hyperoxia is increased levels of oxidative stress and concomitant changes to antioxidant defence systems. Despite these changes, however, the bulk of evidence shows no effect of hyperoxia on growth. Hyperoxia does impact the aerobic metabolic rate of fish with either no effect or elevated resting metabolic rate and substantial increases in maximum metabolic rate. There is also evidence that hyperoxia increases aerobic capacity improves cardiac performance and mitigates anaerobic stress during acute warming. Along with improved upper thermal tolerance in some species, these findings collectively suggest that hyperoxia might provide fish a metabolic refuge during acute warming. Since hyperoxia occurs in shallow aquatic habitats, further research establishing the ecophysiological implications of concomitant heat stress and hyperoxia is pertinent, particularly with a changing climate.

River damming has brought great benefits to flood mitigation, energy and food production, and will continue to play a significant role in global energy supply, particularly in Asia, Africa, and South America. However, dams have extensively altered global river dynamics, including riverine connectivity, hydrological, thermal, sediment and solute regimes, and the channel morphology. These alterations have detrimental effects on the quality and quantity of fish habitat and associated impacts on aquatic life. Indeed, dams have been implicated in the decline of numerous fishes, emphasizing the need for effective conservation measures. Here, we present a global synthesis of critical issues concerning the impacts of river damming on physical fish habitats, with a particular focus on key fish species across continents. We also consider current fish conservation measures and their applicability in different contexts. Finally, we identify future research needs. The information presented herein will help support sustainable dam operation under the constraints of future climate change and human needs.
