Yes, very true. I understand the death rate for shipping WC is especially high compared to CB.
I think the way to arrange trans-shipping for customers located across Canada is to have the source wholesaler actually ship the fish directly to the multiple customers, by-passing the broker/trans-shipper completely. In such a case the buyer takes on 100% of the risk. In return the buyer should get a much lower price. This is a model that I think can work.
Alternatively, the broker/trans-shipper could agree to hold the fish for a period of time. I think 2 weeks is the standard? Within this time the fish should be eating and could then be shipped out across Canada. This model provides the buyer a better guarantee, but should also result in a higher cost. I would think the distribution of loss (should it occur) between trans-shipper/broker and buyer should take into account the final sell price of the fish. If a trans-shipper/broker is making a healthy profit, he can afford to absorb a loss. Not so if the profit is low.
Lots to think about for sure.
