Pollution and Algae Invasions
A clean environment is important in fish farming. Unbalanced ecosystems and pollution levels create problems in the aquaculture industry. Wild fish that detect toxicants in the water try to avoid the danger. Fish reared in sea farms cannot, being confined in pens. Oil spills or discharges of toxic chemicals are thus potentially disastrous for fish farms.
Some got quite a shock in 1988 when there was a staggering bloom of toxic algae along the southwestern coast of Sweden and off the shores of southern Norway. In vast areas algae killed fish and other life in the sea. Several fish farms were emptied, partly because of the algae itself and partly because of emergency butchering. But most installations were saved from the algal death as the fish farmers towed the pens into the safety of the fjords. Some called this algal disaster “the maritime Chernobyl,” and experts claimed that increasing pollution was probably a contributing factor in causing the bloom.
Fish pens in the sea are exposed to all kinds of weather and must withstand ice, rough seas, and storms. When an installation is wrecked and the fish escape, the fish farmer loses valuable property. Moreover, escaped fish might spread diseases to wild fish, and this has been a serious problem. Escaped fish will also compete with wild fish for food and spawning grounds, and there is a fear that this might have a negative influence on local stocks So there is complete agreement that sea installations must be better secured to prevent escapes. Advances have been made in this area too. Aquaculture in Norway says that in recent years “a great deal [has been achieved] when it comes to making aquaculture installations able to withstand extreme weather.](image5997.png)
