Thank you.
I'm not sure we've been given an explanation for why now. You're quite right; the practice of tubbing has gone on for 50 years.
I speak quite frequently with the retired DFO prawn manager, Mr. Jim Morrison. He relayed to me that when the minimum size regulation was brought in, C and P was well aware of the practice of tubbing and that it posed no issue whatsoever. In fact, DFO co-operatively introduced a telson length measurement that would support the ability of C and P to measure frozen prawn tails when they're missing the head portion of the body.
These conversations, which reach back more than a couple of decades, offer us a bit of a glimpse into the context of how this initially came to be. As for why DFO is now looking to take a new view on the tubbed prawns...we're all scratching our heads, so I appreciate the question.
I just wanted to quickly answer the previous question as well. It should be important to note that most communities are not capable of absorbing the full daily catch of the prawn vessels that come into port. I don't believe that the buyers have much at risk in terms of the volume that may be diverted to the tub market. In consideration of what is landed, it's a smaller amount for sure.
The value is where the fishermen can achieve a higher profit in those smaller boutique-style sales and the difference that makes to their personal income.
