The importance of understanding the relationship between water quality, stress and disease cannot be overemphasized. The aquatic environment is very different from the terrestrial one but most husbandry problems may be avoided by routine monitoring of water quality. This chapter introduces physical properties, pH, hardness, alkalinity, dissolved gasses

This is partly attributable to the technical difficulty of isolating viruses from large volumes of water liable to ...

Sampling invertebrates: aquatic environments
1998Abstract This chapter outlines the principles and conditions for use of some of the techniques used to sample invertebrates from aquatic habitats, both fresh¬ water and marine. Many of the principles and apparatus are similar for the two habitats, but there are numerous differences due to scale and ease of access.
