Sustainable Development

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.
Osmoregulation in Fishes02:32

Osmoregulation in Fishes

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?

Summary
This summary is machine-generated.

Fish mortality is a critical welfare issue in aquaculture, often linked to suffering. Analyzing mortality data can improve fish welfare and farm profitability by identifying preventable losses.

Area of Science:

  • Aquaculture
  • Animal Welfare Science
  • Veterinary Medicine

Background:

  • Fish mortality is a significant but under-addressed aspect of fish welfare in aquaculture.
  • Causes of mortality are diverse (biotic and abiotic), often complex to distinguish between underlying and immediate factors.
  • High mortality rates in farmed fish suggest it should be a primary welfare concern.

Purpose of the Study:

  • To encourage fish farming stakeholders to consider fish mortalities within the context of animal welfare.
  • To highlight the potential of mortality data as a welfare performance indicator.
  • To advocate for focusing on preventable mortality when assessing fish farm welfare.

Main Methods:

  • Review of existing knowledge on fish mortality causes and welfare implications.
  • Conceptual framework for using mortality rates as welfare indicators (retrospective and operational).
  • Emphasis on scrutinizing mortality records to identify and mitigate preventable causes.

Main Results:

  • Mortality events are frequently associated with disease outbreaks and critical life stages, likely involving suffering.
  • Mortality rates in farmed fish are among the highest for commonly farmed vertebrates.
  • Mortality data can serve as both a retrospective and operational indicator of fish welfare.

Conclusions:

  • Fish mortality should be recognized as a principal welfare issue in aquaculture.
  • Analyzing mortality records is crucial for implementing targeted interventions to reduce suffering and preventable losses.
  • Improving fish survival through welfare-focused management benefits both the animals and the economic viability of fish farms.
