If nothing is done to halt the large numbers of salmon which currently escape from cages, the escape of manipulated farmed salmon and their establishment in the wild will be almost inevitable in the future. One way of preventing this is by making manipulated salmon sterile. This means that salmon which escape would not be able to reproduce and affect the environment. An additional benefit is that the salmon would not become sexually mature and its meat would therefore retain its quality. Another solution is to locate the tanks on land.

He has been conducting research into fish and growth since the mid1980s. If my research can help to prevent disease or alleviate the problems of world hunger, it is a good thing, even if the results can also be used in a negative way. Naturally, it would be a different matter if the research was carried out with evil intent. However, he is worried about salmon escaping. It would be wrong to allow genetically manipulated animals to become established in the wild.
