Summary: A sudden shift in metabolism has been observed in the early development of Japanese anchovy, coinciding with morphological and behavioral changes. This finding confirms that pelagic fish undergo similar metabolic changes during early development, benefitting future metabolic studies. Additionally, a novel modified respirometry method has been developed to measure metabolic rate changes in this small-sized species.

Summary: The primary goal of aquaculture is to optimize the growth and survival of farmed fishes at a minimal cost. To achieve this, it is important to understand the metabolic changes that occur during development. High intensive aquaculture systems, like recirculating aquaculture systems, require a better understanding of oxygen consumption. This study analyzed the metabolic changes in the F-2 bester during early development and observed ontogenetic phase shifts at specific body mass values.

Summary: The study found a mass dependence in the relationship between field metabolic rates and dynamic body acceleration, requiring coefficient corrections to account for estimation errors in differently sized individuals. Additionally, caution must be taken when applying predictive models developed on one size class to individuals of different sizes due to strong scale dependence in the relationship between metabolic rates and body acceleration.

Summary: The study investigated the prediction of individual FE in European sea bass, identifying significant effects of temperature and population on FE and RMR. However, individual FE and RMR were not significantly correlated, indicating a need for further investigation into the relationship between metabolic rate and feed efficiency.

Summary: This study compared the metabolic rates of two Australian native plant species during cryopreservation and found a significant reduction in metabolic rates, even in tissues that regenerated after cryopreservation. The response to cryopreservation stresses varied among different species. Measuring the metabolic rate of shoot tips provides important information for cellular energy production and shoot health after exposure to cryoprotective treatments.

Summary: This study investigated the impacts of climate change stressors on the Australasian snapper in New Zealand. The results showed that the snapper's metabolic performance remained high even in warm conditions, and they were able to adapt well to hypoxia. Therefore, despite the threat climate change poses to marine organisms, a temperature of 25°C may be metabolically optimal for the Australasian snapper in Northern New Zealand.

Summary: Despite being important in marine aquaculture, little is known about the physiological effects of hydrogen sulfide (H2S) on Atlantic salmon. Recent mass mortalities in recirculating aquaculture systems have highlighted the need for understanding tolerance thresholds and metabolic responses to this toxic gas.

Summary: Interest in measuring metabolic rates is rapidly increasing, particularly in aquatic animal metabolism research. Utilizing intermittent-flow respirometry as a research tool allows for repeated estimation of metabolic rates over time and under various conditions. However, there is a lack of published guidelines for reporting methodological details when using this technique, highlighting the need for standardization in reporting methods.

Summary: This study investigated the associations between relative telomere length and resting metabolic rate, resting fat oxidation, and aerobic capacity in sedentary women, and examined whether oxidative stress and inflammation play a role. The study found that relative telomere length was negatively correlated with resting metabolic rate and high-sensitivity C-reactive protein concentration, and positively correlated with maximum oxygen consumption. Additionally, age and obesity influenced these associations.

Summary: This study investigated the variation in metabolic rate and scaling of metabolic rate with body mass in lake sturgeon populations across different geographical locations and age class. The results showed no significant differences in metabolic rate and mass-scaling between northern and southern populations of lake sturgeon at a temperature of 16 degrees C. This research provided valuable insights for conservation and reintroduction strategies for lake sturgeon populations.

Summary: The hypoxic constraint on peak oxygen uptake was characterized in rainbow trout using different testing protocols and statistical models. The best-fit model was selected based on statistical criteria and the model's prediction of key hypoxic performance points. A curvilinear model with five strategically selected oxygen tensions was found to best describe the hypoxic performance of rainbow trout, with PAAS-50 as a promising metric for comparing hypoxic constraints across fish species.

Summary: Fisheries are complex systems that face challenges from resource management to climate change. Transdisciplinary fisheries research (TFR) integrates different perspectives and knowledge systems, but there are limitations in capacity. Early career researchers' perspectives provide insights into challenges and potential for systemic change. This paper presents the perspectives of ECRs on TFR goals, challenges, and potential. Barriers include institutional inertia, lack of recognition for extra time and labor, and limited skill development opportunities. Actions for ECRs, established researchers, and institutions are identified to reach goals and overcome barriers.

Summary: Female-biased mortality has been observed in Pacific salmon during their adult upriver migration. This study examined whether females are more susceptible to cardiac oxygen limitations after exercise stress. The results showed no significant differences in oxygen levels between males and females, suggesting that females do not suffer from oxygen limitations after a single exercise event upon arrival to their spawning grounds. However, further research is needed to investigate potential oxygen limitations in different conditions and earlier on the migratory route.

Summary: Barotrauma from ice-angling can cause physical injury and physiological disturbance in fish. We tested various barotrauma mitigation strategies on bluegill and black crappie and found that slow retrieval, venting, and re-descension with weights can effectively reduce barotrauma. Black crappie showed less desirable post-release behavior and were less successful in re-descending compared to bluegill. Our findings provide valuable information for anglers to mitigate barotrauma and improve the welfare of released fish.

This article provides an overview of the tagging process and its impact and highlights the lack of standardized holding conditions and durations for tagged fish. The authors emphasize the need for further research and recommend explicit reporting of holding details to benefit fish welfare, science, and management.

Summary: Modified bite-shortened hooks show promise for easy handling and rapid release of fish captured by recreational anglers. The study compared different hook configurations and found that jig style hooks had higher landing success rates. Very bite-shortened hooks allowed for easy self-release while causing less injury compared to regular barbed hooks. The research suggests that bite-shortened barbless hooks could be useful in managing recreational fisheries.

Summary: Human-induced climate change is already having visible effects on the environment and is expected to worsen in the future. The demand for hydropower generation is increasing, but climate change will also impact hydropower operations and the fish population in regulated systems. It is crucial to consider the long-term effects of climate change and incorporate mitigation strategies into hydropower development to protect both fish populations and human livelihoods.

The findings suggest that fish responses to natural changes in flow regimes are mainly negative, but there is no clear generalizable signal across all contexts.

Summary: A national-level synthesis of Canadian restoration ecology research was conducted, showing that restoration research is mainly conducted by academics and focuses on forest, peatland, grassland, and lake ecosystems. The research is concentrated in four provinces and has shifted its thematic focus from reforestation to climate change. This work demonstrates Canada's momentum in ecosystem restoration and provides a model for synthesis in other countries.
