Global Climate Change01:50

Global Climate Change

24.3K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Temperature-Dependent Growth of Brook TroutThe growth of brook trout is closely influenced by water temperature. Experimental data demonstrate how trout weight changes over a 24-day period in response to varying water temperatures. At lower temperatures, such as 15.5 degrees Celsius, brook trout show significant weight gain. However, as the temperature increases, the amount of weight gained steadily decreases. At the highest temperature measured, 24.4 degrees Celsius, trout experience a net...

What is Climate?01:16

What is Climate?

17.4K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Osmoregulation in Fishes

48.7K
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Sustainable Development

12.9K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Area of Science:

  • Animal Welfare Science
  • Aquatic Biology
  • Ethology

Background:

  • Growing attention to non-human animal welfare, particularly fish, across various sectors.
  • Need for updated theoretical approaches and assessment methods for fish welfare since 2006.
  • Increasing recognition of cognitive and affective processes in fish welfare.

Purpose of the Study:

  • To review current theoretical approaches to fish welfare.
  • To highlight recent advances in defining and assessing fish welfare.
  • To explore the integration of fish welfare within 'One Health' and 'One Welfare' frameworks.

Main Methods:

  • Literature review of theoretical approaches and empirical studies.
  • Analysis of outcome- and input-based welfare indicators.
  • Examination of neurobiological, cognitive, and pain perception research in fish.

Main Results:

  • Significant advances in understanding fish cognition, affect, and pain perception.
  • Development of diverse methods for measuring and monitoring fish welfare.
  • Established links between fish welfare, sustainability, public perception, and ethical considerations.

Conclusions:

  • Fish welfare is increasingly recognized as a critical component of ethical practice and sustainability.
  • Integrating fish welfare into broader frameworks like 'One Health' is essential.
  • Ongoing challenges include climate change, cultural perspectives, and understanding fish sentience.
