PREFACE TO THE REVIEW BY PROFESSOR H. LAALE ON THE BIOLOGY AND USE OF THE ZEBRAFISH, BRACHYDANIO RERIO IN FISHERIES RESEARCH
The growing demand for increasingly sophisticated information on the toxic hazards of potential water pollutants has focused attention on the need for a suitable ‘standard’ animal model which could be accepted internationally. The Zebrafish, Brachydanio rerio (Hamilton-Buchanan, 1822, 1823) is considered to be the most likely candidate. It is relatively easy to maintain and breed in laboratory aquaria and it has proved to be responsive to a wide range of mutagens, carcinogens and teratogens, as well as direct toxicants. B. rerio has been the subject of a considerable number of investigations involving a diverse spectrum of disciplines in a number of countries. Professor Hans Laale, who has himself contributed to our knowledge of the embryopathology of B. rerio, has summarized and collated the findings of 450 publications, a number of which are unlikely to have become available to fishery scientists. We hope the publication of this review will aid those who are working with B. rerio and provide comprehensive data on the advantages and limitations of B. rerio as a contender for the standard laboratory fish for the safety evaluation of aquatic pollutants.
