When talking about fishing in EU waters in general, and UK waters in particular you have said:
"it seems like a lot of these 'traditions' both in the UK system and the wider EU one were never codified into actual law."
False. Fishing in EU waters is covered by EU LAW.
"This means that the respective governments voided an agreed contract between private entities"
The EU allocate fishing quotas to applicable member states. The member states then allocate a percentage of their quota to individual fishing vessels registered in a port of the relevant nation. The contracts are btw the member states and the fishermen. These contracts are based on EU quotas for fishing in EU waters. The UK is no longer a part of the EU and so her waters are no longer a part of the EU's waters. If the UK take back control over fishing in their EEZ (just like every other sovereign coastal state) then contracts btw foreign fishing vessels and their government as it pertains to fishing in the UK's waters obviously will no longer be valid. This was always going to be the case. All parties knew that the contracts re fishing in the UK's waters under the CFP were dependent upon the UK being a member of the EU.
"I'm just stating that potentially ripping up contracts in the process is a risky position to take"
Again, the UK government doesn't have any contracts with foreign fishermen. None. So if the UK take back control of their waters next year the result won't be that they will be voiding contracts with French fishermen (as an example) as they never had any contracts with them in the first place.
"the UK government has ALWAYS had final say on the division of the quotas themselves. They've ALWAYS had the option to 'prioritize their own fishing industry over foreign fishing industries', they had simply chosen not to until now"
False. The quotas for fishing in the UK's EEZ were (and until the end of the year still are) determined by the EU and NOT the UK. It was not for example the UK government who determined that French fishermen could catch 84% of cod in Fishing Zone VIId whilst UK fishermen could only catch 9%. The EU decided this. The UK government can only determine what fishermen are able to catch what share of the UK's 9% EU allocation. Even here though they can't prioritise British fishermen as EU law states that all vessels registered in UK ports must be treated equally. This has seen for example Dutch and Spanish trawlers being registered in UK ports and then taking around 45% of the total British quota. And under EU law the UK government could (and until the end of the year can't) do nothing to stop this from happening.
"how much money was injected into the UK economy by the selling of the quotas that created such disparity in the first place?"
Again, the UK government do not set the quotas for fishing in their waters. This is done by the EU through the CFP. The CFP is the reason for the disparity in the first place. End of.
"I wouldn't go so far as to say the French have no grounds to claim access. We could theoretically argue that the French (and others) bought access when they bought the quotas."
The French and other nations DIDN'T buy any access to UK waters as they didn't buy any quotas from the UK. That's not how the CFP works. The EU ALLOCATE quotas to different countries. The countries then sell parts of their quotas to commercial fishermen. Fishermen buy a share of a country's quota on the very clear understanding that the country's quota is allocated by the EU with said quotas only available whilst the country is in the EU.
"I was under the impression that each member state of the EU is assigned species quotas and then were allowed to fish in any waters the EU have access to"
This is absolutely wrong. I don't know why you have that impression but that is definitely not how the CFP works. Not even close.
"If the quotas were set up in the way you describe, keeping track of mobile fishing populations in relation to those quotas would be next to impossible, and fishing them would be incredibly difficult."
And yet somehow it works. Maybe your understanding of fish behaviour is overly limited. Anyway, doesn't matter if you don't see how the system can work, what matters is that's how it does work.
"it says that the UK cannot exceed 32% of the total EU mandated TAC in total and not specifically in UK waters"
No it doesn't. The 32% quota specifically relates to the Uk's share of the total TAC for her waters.
"quotas are assigned by country as a political entity and not as a geographical location"
Nope. Quotas are assigned by country but they are also assigned by area/geographical location.
"The EU doesn't dictate where countries can fish for how long, it only dictates how much they can catch in total"
Absolute rubbish.
"Each country is NOT given a portion of leeway to fish in other countries waters."
If by 'portion of leeway' you mean quota then bollocks. As I have said so many times, applicable member states are allocated a portion (quota) of the total TAC for individual species of fish in individual fishing areas. The quota for nations re fish species varies from area to area.
"Each country is given access to other countries waters through treaties."
They are given access via the CFP.
"The quotas are a separate issue."
No they're not.
"Everyone in the EU can fish in the same waters, regardless of nationality, with limited restrictions set by national governments."
No. Again, fishing in EU waters is controlled by the EU through the CFP. It is not in any way controlled by national governments.
"fish are mobile resources, and as such erecting limits on what can be caught in certain areas is preposterous and extremely difficult."
That may be your opinion but it doesn't change how the CFP works.
"the EU only dictates TAC and I could find no indication that they actually divided up the sea into areas that they put individual quotas on"
Well you didnt look very hard then.
And as an aside you said:
"Legally speaking, the UK has a republic"
Again, no they don't. They have a Constitutional Monarchy which isn't the same thing as a republic.
