Stress insights may inform fish breeding strategies - study
“Our research should help gain new knowledge of health and welfare and aid the development of non-invasive tools to monitor stress in fish and seafood species" - Dr Tim Bean, Roslin Institute.
Scientists will analyse fish DNA to see if stress responses are hereditary.

Researchers at the University of Edinburgh are seeking to discover how to breed fish with greater resilience to disease or environmental stress.

Led by experts at the Roslin Institute, the four-year study will investigate ways to recognise signs of stress in fish and examine fish DNA to ascertain whether their responses to stress are inherited. 

Forming part of a €6m series of studies concerning sustainability in fish, scientists hope their findings could be used to develop strategies that promote improved health and welfare.

Dr Tim Bean, a research fellow at the Roslin Institute, said: “It is essential that we understand how fish and seafood respond to stress and incorporate the findings in breeding strategies so that animals may experience good health and welfare within food production systems. 

“Our research should help gain new knowledge of health and welfare and aid the development of non-invasive tools to monitor stress in fish and seafood species.”

In the study, researchers will analyse the stress responses of key Mediterranean fish species to vaccination and handling. They aim to pinpoint and measure biological indicators of typical stressors through stress hormones and other molecules emitted into the environment by fish.

Scientists also hope to discover whether these responses to stress are hereditary and compare the genetic codes of fish exhibiting various stress responses to identify relevant areas of DNA. The results will be used to improve techniques for assessing stress responses, including physical characteristics linked to resilience.

It is hoped the research will help enhance the wellbeing of fish and shellfish by making it possible to identify animals whose DNA suggests they are robust to stress.

Special imports digital service set to change

News Story 1
 From Monday, 15 July, Special Import Certificate (SIC) applications will only be accepted via the Veterinary Medicines Directorate's (VMD's) new special imports digital service.

The original online special import scheme will be decommissioned. The VMD says that the new service is easier to use, more secure and reliable, and meets accessibility legislation.

The VMD is urging veterinary surgeons who have not yet signed up for the new service to do so before 15 July. The new digital service can be accessed here

RCVS course explains concerns process

A free, online course from the RCVS Academy has been launched, designed to clarify RCVS' concerns procedure.

The content will give veterinary surgeons and veterinary nurses a better understanding of the process, and what they can expect if a concern is raised about them. It includes details of common concerns.

The interactive resource has been developed in collaboration with Clare Stringfellow, case manager in the RCVS Professional Conduct Team.

Ms Stringfellow said: "We appreciate that concerns can be very worrying, and we hope that, through this course, we can give vets and nurses a better understanding of the process and how to obtain additional support."

The course can be accessed via the RCVS Academy. Users are encouraged to record their learning for CPD.
