Animals in research: numbers

At Plymouth University we use a limited variety of species in very small numbers. Details are in the tables below.

Species 2011 2012 2013 2014 2015 2016
Rodents 355 395 1327 1639 2155 2516
Avian 208 142 145 0 0 0
Fish 3054 2319 719 476 540 65


In 2012 the Peninsula College of Medicine and Dentistry was disaggregated and Plymouth University Peninsula Schools of Medicine and Dentistry was formed. This was followed by a marked increase in medical and health research which uses rodents, hence the larger figures.


Avian: This decrease marks the natural end of a research project. 

Fish: This decrease marks both the closing of some research projects and the increased development and use of alternatives and methods to reduce the number of fish used.


Rodents: This increase reflects growth in research groups and success in securing sources of funding for new projects.


Rodents: Increase relates to newly funded research and the maturing of existing research projects. Less marked increase due to greater use of alternatives.

Fish: Decrease relates to the natural closure of research projects and use of alternatives.
