Today's Main Story: Iceland's HB Grandi Pulls Out of Brussels Show Over Security Concerns  Major Icelandic groundfish catcher and processing company HB Grandi will not attend the Seafood Expo Global event in Brussels this year because of security concerns in the city. A group of 27 of the company's employees were scheduled to attend the trade show planned for April 26-28. However, Brussels has been in a state of high terror alert since the March 22 terror attacks in the city's airport and metro station that killed at least 30 people and injured hundreds more. "After careful consideration, HB Grandi management feels it is not justifiable to send employees to Brussels, as is it unclear whether their safety can be sufficiently secured following the recent terrorist actions in the city," the company said in a statement. Alaska Fish and Game officials have closed the Sitka Sound sac roe herring fishery for the remainder of the season. The commercial harvest totaled about 10,000 tons. There were 4,700 tons left to be harvested before Fish and Game shut down the fishery on Monday afternoon. ADF&G biologist Dave Gordon said smaller, younger fish were starting to show up. "The quality of the fish was becoming an increasing concern," he said. In other news Russia held its first auction for Barents Sea snow crab quotas operated by its Federal Anti-Monopoly Service. The auction generated a record $100 million in quota sales for Russia's federal fisheries service. Over 70 companies and organizations bid on the quotas but the winners were not announced. Meanwhile, Dungeness crab fishermen in Northern California got their season underway after agreeing to a $2.90 per pound dock price for their catch. This officially ends a four-month delay to the commercial fishery that was stalled for high levels of toxic domoic acid in the crabs. Finally, Newfoundland's inshore and offshore shrimp fishing fleets are arguing over the economic importance of their operations the region. Ottawa's federal government suspended the controversial "last in, first out" policy in Area 6 this week and a full impact analysis of the fisheries is now underway. Results of the study are expected sometime in April.
