Summary

This study addresses the ethical considerations and welfare of invertebrates in research. It highlights the need for clear guidelines for Institutional Animal Care and Use Committees (IACUCs) regarding invertebrate pain and nociception.

Area of Science:

Zoology
Animal Welfare Science
Research Ethics

Background:

Invertebrates are the most diverse animal group used in research, yet their welfare and ethical considerations are not well-defined.
Current practices often categorize invertebrates into two groups based on moral concern, leading to inconsistent regulation and documentation.

Purpose of the Study:

To address challenges faced by researchers and Institutional Animal Care and Use Committees (IACUCs) regarding invertebrate welfare.
To provide practical information for managing ethical and regulatory issues in invertebrate research protocols.

Main Methods:

The study reviews existing literature on invertebrate nociception and welfare.
It presents two case studies of invertebrate research protocols to illustrate specific concerns.

It offers guidance on various aspects of invertebrate research management.

Main Results:

Inconsistent approaches to invertebrate welfare exist, with some taxa (e.g., cephalopods, decapod crustaceans) receiving greater moral consideration.
There is a lack of clear understanding and standardized practices for assessing pain and nociception in invertebrates.
Practical challenges include sourcing, record keeping, risk management, housing, husbandry, invasive procedures, veterinary care, and humane endpoints.

Conclusions:

Standardized ethical guidelines and improved understanding of invertebrate sentience are crucial for responsible research.
Addressing the identified practical matters will enhance the welfare of invertebrates used in scientific research.
