The last week has seen IntraFish once again unearth some big-hitting stories.

None fit into this category more than the video of the undercover footage that has Cooke's Maine farmed salmon operations in trouble for the deliberate mistreatment of fish by its workers.

IntraFish revealed later that a plant-based seafood investor has ties to group targeting Cooke.

Further afield and looking to Asia, Australis Seafoods is leaving New World Currents, a Chilean joint venture set up to sell salmon in China. Now under Chinese ownership, the company is ready to enter the market alone.

After the recent week's shock announcement that salmon farmers in British Columbia will have to transition from open net pen salmon farming in coastal waters to closed containment systems should Justin Trudeau be reelected in Canada, salmon farmers swarmed social media to blast Trudeau ahead of the election.

Although no less interesting, IntraFish reporter Nina Unlay returned to something of a familiar theme this week albeit as Bakkafrost unveiled plans to power households with salmon mortalities and feces.

This week IntraFish lifted the covers on a couple of quite different expansion plans as one GM salmon producer AquaBounty eyes rural America for its next farming site and a US land-based coho salmon producer targets a nationwide expansion.

As the canned tuna price fixing legal saga rumbles on the former Bumble Bee CEO wants salary, bonuses kept from the jury, with attorney's arguing that his millions in pay would unfairly prejudice the jury.

Staying with legal matters IntraFish reporter Rachel Sapin reported on the founder of a US shrimp supplier convicted of sex trafficking.

And finally this week, AquaStar, Ocean Garden, other US shrimp importers have joined forces to tackle the scourge of Mexican shrimp 'laundering', meaning vendors can expect much tighter checks on shrimp provenance paperwork as processors introduce code of conduct.

Finally, in late-breaking Friday afternoon news, the government of Newfoundland suspended the salmon farming licenses of all of Mowi's operations, and the minister called for an in-person meeting with CEO Alf-Helge Aarskog.
