As the Alaska pollock "B" season -- which started in early June -- heads into mid-July, producers remain concerned about the size of the fish being caught.

Fish are still coming in at the 400-500-gram range, confirmed one executive with a major Alaska catcher processor. It's a bit of a bump up from the size of the fish producers saw in June -- which ranged from 250 – 350 grams -- but still not ideal.

Prices remain high, with inventory tight for both deep-skin and pinbone-out (PBO) fillets, with PBO continuing to sell for record highs at around $3,900 (€3,289) per metric ton, the executive said.
