What can we learn from established health
monitoring practice for other species?

Health
monitoring/health screening of laboratory animals is a form of health control
that also has a great impact on the welfare of the animals. Health control has
been practised for many years as even at the beginning of the last century
Governments controlled the health of farm animals and animals crossing borders.
In the
early 1950's health control started seriously with mammalian laboratory animals
in the United Kingdom and was administered by the Medical Research
Council. These controls were primarily
aimed at ensuring a standard quality of animal from laboratory animal
breeders. At the end of the 20th
Century this was refined by FELASA with two sets of guidelines, one for the
breeding of animals and the other for animals in experiments and recently both
were combined within one new set of guidelines.
What is
now standard practice with mammals is not directly applicable to fish. There are no dedicated suppliers of fish,
breeding fish for laboratory use only.
Therefore controls on the supply are much more difficult to
organise. In addition the environment
of the fish ie water makes the direct transfer of mammalian practice almost
impossible.
However
there are some areas where fish can be regarded in the same way as mammalian
laboratory animals and examples of this are the statistics involved in
determining sample sizes and the laboratory technology.
The paper
will discuss the similarities and differences in more detail.
