Summary: China is the largest producer of food fish in the world, and consumers in China prefer to buy live fish for freshness. Live fish transport is common in Chinese aquaculture, but poses potential risks to animal welfare. This study explored stakeholders' attitudes and knowledge towards live fish transport and welfare in China. Results showed that participants had moderate knowledge of transport practices and some understanding of animal welfare, though mainly focused on terrestrial animals. Live fish transport in China often involves sealed tanks, plastic bags, and foam boxes in purpose-built vehicles, with seasonal changes and oxygen supply being key factors. Anesthetics are not widely used, and fish health during transport is mainly assessed based on physical appearance and swimming ability. Participants tended to associate welfare concerns more with terrestrial animals than with fish.

Summary: Aquaculture is the fastest-growing production segment, requiring clear guidelines on fish rearing, stunning and slaughter for animal welfare. Validating dorsal fin erection as a painless indicator of sensibility in Nile tilapia is effective and practical in large-scale production systems. However, the presence of an erect dorsal fin alone does not ensure fish insensibility, necessitating the use of other visual sensibility indicators.

Summary: Animal welfare is an integral part of livestock production and sustainability. Qualitative Behaviour Assessment (QBA) is a technique used to assess animal welfare, with behavior being a key component. Video-QBA (V-QBA) is a method that uses video footage for assessment, and studies have found broad agreement between V-QBA and live QBA results. However, caution should be taken when implementing V-QBA due to the lack of absolute agreement and lower scores obtained in some cases.

Summary: The study investigates the mortality of live-born piglets under different confinement periods and farrowing pen types. The results show that confining the sow for three days after farrowing is an effective measure to reduce piglet mortality, and extending the confinement period to five days does not further reduce the mortality rate.

Summary: Dehooking tools and bare hands were compared for their efficacy in removing hooks from Bluegill fish caught with barbed and barbless hooks. Bare hands took the longest time, while there was little difference in dehooking times among the tools used. However, using tools resulted in more tissue tearing compared to bare hands. Barbed hooks took significantly longer to remove than barbless hooks, and there was an increase in tissue tear size for fish caught on barbed hooks. Larger fish took longer to dehook, but tearing was not size-dependent. Bleeding incidence was low and not significantly different among treatments. Reflex impairment was observed only in fish caught on barbed hooks with longer dehooking times. Overall, using barbless hooks is more important than the specific dehooking tool used.

Summary: This study investigated the potential effects of red tide events on Atlantic tarpon along the southwestern coast of Florida. The results showed that tarpon are somewhat tolerant to red tide blooms, but when the blooms overlap with tarpon peak abundance and become dense and large, tarpon may leave the affected area or suffer mortality. Additionally, the study found an increase in the overlap of red tide blooms with tarpon spawning season. Combining multiple data sources helped elucidate how red tide exposure influences tarpon and the recreational fishery that targets them.

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: The common carp is a non-native fish species that negatively impacts freshwater environments. Conventional management focuses on using barriers to control or contain the carp, but the impacts on native species should also be considered. Different biological traits, such as phenology, sensory ability, morphology, and behavior, can be exploited to design barriers that minimize the ecological impacts on native species.

Summary: Fishways can restore functional connectivity within rivers for migratory fish, but their success can vary. A study on the passage success of Chinook salmon in the upper Yukon River found that it was low overall, particularly for female salmon. In contrast, salmon migrating in a nearby free-flowing river had high migration success. The findings suggest opportunities for improving fishway performance and connectivity for this impressive animal migration.

Summary: During spawning migrations, adult Pacific salmon must undergo changes in gene expression and behavior to adapt to stressful conditions. Assessments of physiology and infectious agent presence in gill tissue can provide insights into these adaptations. The study found that migrating salmon exhibited decreased thermal stress gene expression and showed evidence of cooler water selection, suggesting behavioral changes and potential benefits of thermal refuges in reducing the negative impacts of infection.
