“…The relatively new industry in Norway based on the live export of king-and snow crab will rely on a consistent supply of wild-caught crabs, held in land-based facilities for periods varying from a few days to a few months (James, Vasilyev, Siikavuopio, Kovatcheva & Samuelsen 2013;Lorentzen et al 2015;Siikavuopio & James 2015;Siikavuopio et al 2016). During this 'transit' period when they are held in land-based facilities they will need to survive and maintain their quality at an acceptable level for both animal welfare standards and for discerning export markets.…”

“…Since then, new stocks have been located almost every year. The snow crab seems to be permanently established in the Barents Sea, as illustrated by the commercial landings of snow crab of 4000 tonnes in Norway representing an export value of approximately NOK 100 mill (Lorentzen, Rotabakk, Olsen, Skueland & Siikavuopio 2015). Snow crab occurs mainly in the eastern Barents Sea, but animals have also been recorded in the western parts of the Barents Sea (Pavlov & Sundet 2011).…”

“…Consistency of supply is ensured by holding the snow crabs in land-based holding facilities for extended periods while maintaining their condition and meat content (Lorentzen et al 2015). The development of live holding and export of snow crab from Norway depends on both a reliable and consistent supply of crabs and the ability to hold and transport these, in good condition, to overseas markets.…”

Consistency of supply is ensured by holding the snow crabs in land-based holding facilities for extended periods while maintaining their condition and meat content (Lorentzen et al 2015). Capture-based aquaculture of snow crab is developing in Norway and several other countries, and effort has been put into establishing smalland medium-sized enterprises using intensive culture systems for live holding snow crab (Lorentzen et al 2016).…”

In this study the effects of different stocking densities on survival, injury and weight of captive male snow crab were examined. The first experiment (I) was carried out in square plastic tanks (700 L) with stocking densities of 100 (L), 150 (M) and 200 kg m À3 (H) for 30 days. In a second experiment (II) snow crabs were kept at a stocking density of 50 kg m À3 and were either fed (F) or not fed (S) for the same period of 35 days. The last experiment (III), was carried out with stocking densities of 25 kg m À3 for 21 days with two groups, one with inactivated claw and one without rubber bands, with three replicates per treatment. In the first experiment mortality (H = 27, M = 26 and L = 36%) and occurrence of injuries (H = 27, M = 20 and L = 16%) were high in all groups. The weight loss during the experimental period was; H = 15.3, M = 10.9 and L = 15.5 g, and was not significant different between the groups. In experiment II the mortality (F = 13% and S = 14%) and injuries were lower (F = 12% and S = 17%). The average weight increased in the fed treatment and decreased in the starved treatments. In the last experiment there was no mortality in any of the groups and the levels of injury were low (5% and 7%). The results show that adult male snow crab cannot be stored at densities equal to or higher than 25 kg m À3 for 3 weeks without risk of mortality.

“…In recent years, snow crab from the Barents Sea has accounted for about 10% of the global supply, with Canada the leading global contributor with 55%-60%. Other countries producing snow crab include Alaska, Russia, South Korea, and Greenland (Dawe & Colbourne, 2002;Lorentzen, Rotabakk, Olsen, Skueland, & Siikavuopio, 2016). In Norway today, most of the by-products are discarded, regardless of whether the crabs or shrimp are processed onboard or on land.…”

Testing baits prepared from by-product of the shrimp and snow crab industry in the pot fishery for Gadus morhua (Linnaeus, 1758) and Pollachius virens (Linnaeus, 1758)

Summary In a study between October and November 2015 in northern Norway, bait prepared from the by‐product of the shrimp and snow crab industry was employed in the pot fishery to capture cod and saithe. Frozen natural herring was used as control bait. Pots with the three bait types were placed 1,000 m apart in order to eliminate the risk of interaction between the different baits. In total 11 sampling periods were conducted. There were no significant differences in catch rates between the different baits tested on cod and saithe. The manufactured bait tested in this study showed a continuous release of odours over a 14‐day period. Results show that the water content of the bait increases rapidly in the first phase of the immersion (until day 7), and the corresponding loss of bait mass (dry weight) suggest some physical disintegration (erosion) of the bait until the water content stabilizes. This study illustrates that it is possible to replace natural herring with hydrolysates from by‐products from shrimp or snow crab industry in the Norwegian pot fishery of cod and saithe.

Total volatile basic nitrogen (TVBN), biogenic amine, total viable count (TVC), volatile compounds, and sensory evaluation were conducted to assess the quality of Chinese Mitten Crabs (Eriocheir sinensis) at living, zero, 2, 5, 10, 15, and 24 hr postmortem. The sensory evaluation found a noticeable odor of spoilage becoming evident 10 hr postmortem. The TVBN value increased and then decreased as time increased, reaching 23.67 mg N/100 g at 24 hr postmortem. Although biogenic amines were detected at 5 hr postmortem, by 24 hr postmortem these had not reached dangerous levels of toxicity. The initial TVC (6.06 Log CFU/g) of the living crab samples was relatively high and climbed further postmortem, reaching 10.00 Log CFU/g 24 hr postmortem. Trimethylamine was detected in the living sample in belly meat and 2 hr postmortem in crab roe and reached 8.33 µg/g in the roe 24 hr postmortem. Indole was detected at 0 hr (belly meat) and 10 hr (crab roe) postmortem, but did not change significantly during the observation period. Sulfur‐containing compounds were detected 5 hr after death and gradually increased over the observation period. Most indicators showed major changes at 5 hr and 10 hr postmortem. By 10 hr postmortem, the crab had entered the putrefaction stage and was thus no longer safe for consumption.
