The BBC says:

UK waters may become more productive fishing grounds as climate change brings new species in from the south, according to researchers.

Fish such as red mullet, hake and sole have become more abundant in the last 30 years, as the waters have warmed.

But established favourites such as cod and haddock may be on the wane.
Overall, three-quarters of the species in the area are responding to rising water temperatures, the team found.

And of those, three times as many are increasing in abundance as declining.
The team behind this study - drawn from eight UK research institutes and one in the Irish Republic - emphasises there is no guarantee that abundances of these species will continue to rise.

Each one needs not only water of a given temperature range but also factors such as a secure food supply and the right environment for reproduction.

The impact of ocean acidification is also unknown, but unlikely to be beneficial given the evidence so far.

But if warming water is the main factor, the trends seen over last three decades are likely to continue, because further temperature increases are expected.

It is to be expected that global warming brings some benefits as well as problems, for humans, although this rarely gets mentioned in the media. The real problem is the rate of change, not the change itself.
