Climate change is affecting our ocean. Fishing and aquaculture is Norway’s second most important industry. The temperatures in the ocean are rising.
This higher temperature will cause an increase of anchovies and sardines. However it will cause there to be less herring and cod. Hence cod, haddock, herring and capelin will move eastwards to colder waters. And also the snow crab is moving north and it has seen in the Barents Sea.
Aquaculture is like farm ﬁshing, weather inﬂuences life in the ocean. Higher temperature can also lead to decreased oxygen levels. Enrichment of organic matter and outbreaks of algal blooms that spread diseases to the ﬁsh and deteriorate conditions for ﬁsh farming.
