I began writing it last Monday, and each day has brought a new revision as the world (including myself) became more and more sober about exactly what is happening, and what may come.
None of us are sure, and with every browser refresh comes a new piece of information that we have to try to integrate into our rapidly changing world view.
So while the life-span of news and analysis appears to be shortening, it's safe to say that some long-term impacts from coronavirus are becoming clear, and it doesn't look good for anybody.
Seafood, which is reliant on consumer spending and the free flow of trade, is going to be hit hard in particular.
Will the industry stop? No. People need to eat, and seafood remains a crucial part of the food supply. Exactly how it gets to consumer plates, however, is going to be radically reshaped.
Restaurants
What’s happened so far: Dining destinations are being forced to shift to takeout and delivery only -- or to shut down entirely.
What they’re asking for: They’re urging patrons to buy gift cards, reschedule reservations, and get that grub delivered. 
  • But the industry’s 15m+ workers are losing out on shifts and tips right now, and owners still have bills to pay.
What might happen next: Governments might have to step in to prevent widespread industry collapse. As Eater put it: “Restaurants Are F*cked -- Unless They Get a Bailout.”

Industry is coming back home. in a world where borders have been slammed closed, and  means a complete rethink of how seafood medicine, automobiles and EVERYTHING gets processed, and companies will want and need more control.
The investments in domestic (or nearby) processing will not be temporary, and a new level of conservatism about supply chains will be here for a long time to come.

Coronavirus is accelerating a change that was already underway: the decreasing dependence on China as the world's producer of anything...
Ironically, China's agressive measures to contain the virus will have it recovering long before the rest of the world, expect Americans to revolt, ignore, and sue any attempt at lock-down or control of the society, we simply are too unlearned to ever understand sacrifice.
While that will have China's consumer economy returning to "normal" sooner than others, the shock to the global flow of goods will shake a lot of companies to their knees: it no longer makes sense to put all your manufacturing and supply eggs in one basket.
Anti-globalists will force America to return the control of our patents, design staffs, and manufacturing to US soil.... count on it.... pharmaceuticals and medical technologies, automotive components, and anything warfare connected will be force back to North America... where we can at least invade to secure things.
What was once an interesting idea market (online sales), is going to become the norm.
Brick-and-mortar stores are in some cases experiencing a short-term uptick, but as Western minds marinate in the severity of the coronavirus crisis, being out in public (exposed),  online retailing is going to boom in an unprecedented way.
Once the supply chain begins to shift and consumers develop new online habits, they will never return to shopping in-store in the way they have.
A massive overhaul in how seafood is sold as well, from packaging to messaging to product forms.  Canned fish is having its moment in the sun. But if ever there were a short-term panic buy, it's canned tuna and salmon. Don't expect that trend to last, as an old Star-Kist veteran of the Tuna wars, fish is dead....
Foot traffic is already plummeting at retail.as virus fears spread, consumers that do shop brick-and-mortar stores will be looking for a lot less people to touch their food, bringing in closure of meat and seafood counters.
Pre-packed (frozen) meats and  fish will continue to deliver in a more reassuring way, by eliminating the "touching-coughing-sneezing-nose picking food service worker, gally cook, chef, or wait person...

It's hard to overstate the impact that the global shutdown will have on the restaurant, hospitality and institutional food business. Individual and small-chain restaurants operating on small profits cannot survive a six month slow/shut down...
Take out is a joke that will be figured out as "nasty" by the consumer (sooner or later), and food safety low volume selling going in/out/in/out of the reefer with reheat, cool down/ reheat could own will eventually poison customers (especially after being coughed into).
export sales will cease, the inward sales market will be very competitive, and companies will have to return to prices over volume sales.  I've been among the most negative on land-based aquaculture (salmon in particular), remember, we pioneered this industry back in the 1980's at our Tactician fisheries development Talapia farming in the Caribbean.... you know where that went....
But, there's no question that its a trend that won't go away; expect many new startups and high tech  projects, but health concerns and the lack of finances may end the dream.
Suddenly, producing fish domestically has become a far more interesting proposition. The proximity to markets is now a major asset -- not simply a justification for lower shipment costs. Any people or companies that failed to invest in digital tools -- from laptops to TV-systems to inter-company communications -- are realizing that they should never have put off spending their money on tech. or learning how to use it daiy.
I have been wrong more times than I can count with predictions over the years, and, I sincerely hope I am again, but even if we all beat this thing back in the next six months, life and commerce for the seafood sector will indeed change forever -- that I am sure of.
