A likely outcome of an increase in UK fishing quotas is that UK fishing fleets end up hiring migrants from places like Egypt and Tunisa to staff fishing boats as the increase in capacity isn't matched by an increase in the number of British people willing to work in the industry

All this risk loaded up in Brexit negotiations by the UK government over control of fishing waters ends with incremental gains that are a rounding error for the wider economy for fishing fleets that may end up importing labour from North Africa and need access to EU markets

Worth taking a closer look at the working practices of an industry when discussing how gains for it in a trade negotiation might affect economy and society
