REPORT on the NORWEGIAN FROZEN FISH FILLET Industryl/ by R
August 1953 Washington 25, D.C. Vol. I 5 , No.8 : REPORT ON THE NORWEGIAN FROZEN FISH FILLET INDUSTRyl/ By R. T. Wh i teleather* FILLETING INDUSTRY IN GENERAL The fisheries that support the groundfish fillet industry in Norway are lo cated in the northern part of the country principally from the Lofot Islands area northward to Hammerfest in Finnmark. These fisheries, particularly those for cod, are generally ranked among the most prolific in the world. In a normal year the Lofot fisheries alone from January through March yield from 80,000 to 120,000 met ric tons of large cod. Notwi t hst anding this, the 1953 spring fishery for cod was disastrous owing to violent storms and almost continuous bad weather for the two- onth period which comprised most of the season. No trawlers operate in t he Lofot cod fishery. The purse seiners, gill netters, ong liner., and hand liners used are dependent to a great extent on reasonably air weather conditions.

In teleost fish crude oil exposure, with the associated polycyclic aromatic hydro- carbons (PAH's), reduces exercise performance and this has been hypothesized to be due to compromised car- diovascular function. In this study, we test this hypothesis by simultaneously measuring cardiovascular per- formance, oxygen consumption, and swim performance in a pelagic teleost, the cobia (Rachycentron canadum). Metabolic rate increased over 300% in both groups during the swim trial but as the fish approached the critical fi swim speed (Ucrit) MO2 was 12% lower in the oil exposed sh. Further, stroke volume was initially 35% lower while heart rate was 15% higher in the oil exposed compared to control fish. Our findings suggested, while aspects of cardiovascular and metabolic function are altered by oil exposure, additional studies are needed to further understand the homeostatic mechanisms that may sustain cardiovascular function at higher exercise intensities in cobia. -

Total Mercury and Copper Concentrations in Lake Trout and Whitefish Fillets from Lake Superior
Total Mercury and Copper Concentrations in Lake Trout and Whitefish Fillets From Lake Superior Activity: 19 -23 By Kory Groetsch Environmental Section Biological Services Division INTRODUCTION Mercury and copper are the two most toxic heavy metals to fish. Furthermore, methyl mercury can accumulate in fish muscle tissue to levels that, consumed on a regular basis, may pose a risk to human health. Both of these metals are released during copper mining and ore processing. Copper mining and processing were a major industry in the Keweenaw Peninsula of Michigan during the mid-1800's. Mining processes which involved heating the ore, released mercury as a bi-product into the air. Furthermore, the unused portion of the ore after the desired minerals were removed (i.e. tailings) were dumped off the shoals of the Keweenaw Peninsula into Lake Superior. These tailing have formed large sholes referred to as stamp sands. Because the extraction of copper from the ore is not a 100% efficient process, it is reasonable to assume that copper, as well as mercury, were in the tailings released into the waters around the Keweenaw Peninsula. The waters around the Keweenaw Peninsula are the location of several lake trout and whitefish spawning reefs. The lake trout and whitefish populations around the Keweenaw Peninsula are sustained by the fish reproduction that occurs on these reefs. These lake trout and whitefish populations have significant cultural and economic importance to the Anishinabe. The purpose of this study was to determine the total mercury and total copper concentrations in the muscle tissue (i.e. fillet) of lake trout and whitefish, in size ranges commonly caught by tribal fishermen around the Keweenaw Penisula. -
Activity and Food Choice of Piscivorous Perch (Perca Fluviatilis)
Freshwater Biology (2002) 47, 2370–2379 Activity and food choice of piscivorous perch (Perca fluviatilis) in a eutrophic shallow lake: a radio-telemetry study LENE JACOBSEN, SØREN BERG, MADS BROBERG, NIELS JEPSEN and CHRISTIAN SKOV Danish Institute for Fisheries Research, Department of Inland Fisheries, Vejlsøvej, Silkeborg, Denmark SUMMARY 1. Radio transmitters were implanted in large perch (27–37 cm) in a shallow lake in Denmark. Between 6 and 13 perch were tracked every 3 h for 24-h periods twice (summer) or once a month (winter) from August 1997 to July 1998. Activity levels were recorded as minimum distance moved per hour. 2. No significant differences in activity levels of individual fish were observed. 3. Highest activities were observed at daytime with peaks at dawn and dusk or midday. This diel pattern was most pronounced from October to April, whereas diel variations were less in the summer months, with no peaks occurring in midsummer. The general lack of activity at night supports the idea that perch is a visually oriented forager. 4. There was no significant relationship between daytime activity during the year and temperature or day length, but nighttime activity was correlated with temperature. In contrast with previous findings, activity levels varied little seasonally, except for high activity levels that occurred concomitantly with high temperatures in August. Instead, we found a significant relationship between the total distances moved per day and temperature, indicating that perch moved at the same average speed in the wintertime, but did so for shorter periods than in summer because of shorter day lengths. 5. -

Fillet Steak with Slow-Cooked Tomatoes, Salsa Verde Watercress
Fillet steak with slow-cooked tomatoes, salsa Verde watercress The fillet is probably the nicest and most expensive cut of beef. It’s very lean and tender due to the short fibres in the meat. Salsa verde not only contains lots of vitamins, it also bursts with freshness from the herbs and savoury anchovies. With the slow-cooked tomatoes and watercress salad, this is a recipe that will have you looking forward to steak night. Remember to stick to no more than 1 tablespoon of balsamic vinegar per sitting. Ingredients-serves 4 . 4 x 100g fillet steaks For the slow-cooked tomatoes: . 520g/4 vine-ripened tomatoes or 16 . cherry tomatoes . 2 sprigs of fresh thyme . splash of balsamic vinegar . splash of olive oil . pinch of caster sugar . salt and freshly ground black pepper For the salsa verde: . 2 tsp white wine vinegar . 4–5 fresh basil sprigs, leaves only . handful of fresh flat-leaf parsley . 6g/2 tinned anchovy fillets, drained and finely chopped . 3 tsp capers . 100ml garlic-infused olive oil For the watercress salad: . 100g watercress . 4 tbsp olive oil . 1 tsp white wine vinegar . 1 tsp Dijon mustard . pinch of salt Method Preheat the oven to 120°C. To prepare the slow-cooked tomatoes, combine the thyme, vinegar, oil, sugar and seasoning and dip the tomatoes (still on the vine) into the mix, coating them completely. Place on a baking tray and gently roast them in the oven for 15–20 minutes. Heat a large frying pan over a high heat until it’s smoking hot, then brush with olive oil. -
Clean &Unclean Meats
Clean & Unclean Meats God expects all who desire to have a relationship with Him to live holy lives (Exodus 19:6; 1 Peter 1:15). The Bible says following God’s instructions regarding the meat we eat is one aspect of living a holy life (Leviticus 11:44-47). Modern research indicates that there are health benets to eating only the meat of animals approved by God and avoiding those He labels as unclean. Here is a summation of the clean (acceptable to eat) and unclean (not acceptable to eat) animals found in Leviticus 11 and Deuteronomy 14. For further explanation, see the LifeHopeandTruth.com article “Clean and Unclean Animals.” BIRDS CLEAN (Eggs of these birds are also clean) Chicken Prairie chicken Dove Ptarmigan Duck Quail Goose Sage grouse (sagehen) Grouse Sparrow (and all other Guinea fowl songbirds; but not those of Partridge the corvid family) Peafowl (peacock) Swan (the KJV translation of “swan” is a mistranslation) Pheasant Teal Pigeon Turkey BIRDS UNCLEAN Leviticus 11:13-19 (Eggs of these birds are also unclean) All birds of prey Cormorant (raptors) including: Crane Buzzard Crow (and all Condor other corvids) Eagle Cuckoo Ostrich Falcon Egret Parrot Kite Flamingo Pelican Hawk Glede Penguin Osprey Grosbeak Plover Owl Gull Raven Vulture Heron Roadrunner Lapwing Stork Other birds including: Loon Swallow Albatross Magpie Swi Bat Martin Water hen Bittern Ossifrage Woodpecker ANIMALS CLEAN Leviticus 11:3; Deuteronomy 14:4-6 (Milk from these animals is also clean) Addax Hart Antelope Hartebeest Beef (meat of domestic cattle) Hirola chews -

Evaluation of Food Waste Prevention Measures— the Use of Fish Products in the Food Service Sector
sustainability Article Evaluation of Food Waste Prevention Measures— The Use of Fish Products in the Food Service Sector Yanne Goossens * , Thomas G. Schmidt and Manuela Kuntscher Thünen Institute of Rural Studies, Bundesallee 64, 38116 Braunschweig, Germany; [email protected] (T.G.S.); [email protected] (M.K.) * Correspondence: [email protected] Received: 15 July 2020; Accepted: 11 August 2020; Published: 15 August 2020 Abstract: This study presents two food waste prevention measures focusing on the interface between the food service sector and its food suppliers. Through a case study on procuring salmon by a hotel kitchen, the use of food products with different convenience grades is examined. The convenience grade of the fish bought (whole salmon, fillets or portions) determines where along the food chain filleting and/or portioning takes place and thus where food waste from cut-offs occurs. To reduce food waste, we propose purchasing filleted or portioned salmon rather than whole salmon. For both measures, effectiveness is calculated by looking at food waste reductions along the food chain, achieved by a better use of filleting and portioning cut-offs. Next, sustainability across the environmental, economic and social dimension is evaluated by calculating (a) avoided embodied environmental impacts and economic costs, (b) avoided food waste disposal environmental impacts and economic costs and (c) environmental, economic and social impacts and costs associated with implementing the measures. Purchasing fillets or portions instead of whole salmon leads to food waste reductions of 89% and 94%, respectively. The interventions further lead to net climate change impact savings − − along the salmon chain of 16% (fillets) and 18% (portions). -
