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. -
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 -

Oppgavetittel: Sild I Kokebøker Rundt Nordsjøen Mellom 1837 Og
Masteroppgave i Kulturmøte Oppgavetittel: Sild i kokebøker rundt Nordsjøen mellom 1837 og 1929. Fellestrekk og forskjeller i Danmark, Norge og Skottland. Studiepoeng: 60 Forfatter: HansMorten Sundnes Måned / år: 11/2020 HØGSKULEN I VOLDA | BOKS 500 | 6101 VOLDA WWW.HIVOLDA.NO | T:70 07 50 00 | F: 70 07 50 51 Forord Da jeg vokste opp på 1960- og 1970-tallet, fikk jeg som regel pølse da de voksne hadde sild. I samme periode skrumpet jo den viktigste norske sildebestanden inn og ble nesten borte en periode. Under en reportasjetur utenfor Florø på slutten av 1980-tallet dukket det litt uventet opp sild i torskefangsten; journalisten fikk ha med seg hjem og stekte til middag. Og det har jo også vært både sildesalat til jul og rene sildebord i voksenlivet mitt. Jeg ble likevel en del av Sildas sivilisasjon, som den italienske historikeren Giovanni Rebora omtaler det nordlige Europa som. I Kulturmøte-studiet lærte jeg om Nordsjøbassenget som en mulig kulturmøtearena for landene rundt, og jeg at tenkte at også silda, som i stor grad befinner seg mellom nordsjølandene, kunne være et slags kulturmøtepunkt. Samtidig synes jeg kokeboka er litt undervurdert og lite utprøvd som kilde, og en oppgaveformulering begynte å ta form. Dette masterstudiet har skjedd ved siden av jobb. I tillegg har det dukket opp andre utenomprosjekter som har skjøvet studiet på sidelinjen. Dette har gjort at det også ble flere veiledere underveis: Først Atle Døssland, siden Dag Hundstad og så Atle Døssland og Erik Fooladi sammen. Jeg er glad for at det tross alt ble mulig å gjennomføre og setter pris på bidragene og tålmodigheten til alle disse. -
Salted and Pickled Fish, Smoked Fish, Fish Fillet, Frozen Seafood
How to Start Fish Processing Business (Salted and Pickled Fish, Smoked Fish, Fish Fillet, Frozen Seafood) Fish is a valuable source of high quality protein and, in the case of oily fish, fats of considerable nutritional importance. In many countries, large-scale commercial fish processing (mainly freezing for export and canning) takes place in parallel with traditional processing. The methods used by smaller enterprises remain based on traditional techniques of drying, salting, smoking and fermentation. www.entrepreneurindia.co There are more than 27 000 species of salt and freshwater fish; many more crustaceans, bivalves, and cephalopods can also be eaten. Fish and shellfish are the only foods that, globally, are still obtained in significant quantities from the wild. But many species are on the verge of commercial extinction and aquaculture is increasing worldwide. For instance, more than a third of the salmon eaten worldwide is farmed. Like meat, fish is also processed, for instance by drying, salting, and smoking. www.entrepreneurindia.co India is endowed with the largest livestock population in the world. Livestock and poultry in Indian tropical and sub tropics play a critical role in agriculture economy by providing milk, meat, eggs etc and provide flexible reserves during period of economic stress and buffer against crop failure. Mutton and Chicken is an important livestock product which in its widest sense includes all those parts of the animals that are used as the food by the man. So, with increase in population there is also an increasing consumer demand for food products that are low in fat, salt and cholesterol at local, national and international levels. -

Fillets from farmed yellow perch (Perca flavescens) fed with a commercial diet were compared to wild yellow perch fillets from the Great Lakes of the United States. Mineral, fatty acid and amino acid contents, proximate composition, texture, color and sensory analyses were determined for both treatments. The data were subjected to one-way ANOVA using the statistical analysis system (SAS). Fat content of farmed yellow perch was significantly higher, while protein content was significantly lower, than wild yellow perch. A variety of fatty acids was significantly different between wild and farmed yellow perch. For example, arachidonic acid (20:4 n-6) was significantly higher (Pp0.05) in wild yellow perch fillets; however, no significant differences were found in the total amount of n-3 fatty acids (30% of total fatty acids). -

It is accessible by a gravel road that crosses the outlet. The 2-mile long outlet to Lobster Lake has no physical barriers to fish migration. Large populations of white perch, yellow perch, and suckers limit the ability of the pond to maintain a desirable brook trout fishery. By mid-summer, there is a deficiency in dissolved oxygen at depths below 20 feet. In 1969, the Department constructed a barrier dam on the outlet and attempted to reclaim Little Lobster Lake using rotenone. Shortly after the reclamation the barrier dam washed out and all of the original species reestablished. In the early 1980’s, Little Lobster Lake was one of two waters chosen to test the potential of landlocked salmon treated to be sterile. The purpose of the trial was to produce above-average-size salmon. The treatment and the test failed and the project was discontinued. A few wild salmon and wild brook trout will be produced each year. However, the principal management should continue to emphasize white perch.

Maximum depth - 106 feet 90 feet - 49° F. Suggested Management The view of nearby mountains and white sand beaches makes Lobster Lake one of the most beautiful lakes in Maine . .Water quality conditions are excellent for coldwater game fishes, and the lake should be managed for its existing popula• tions of salmon and togue. It is unfortunate that yellow perch, white perch, and other fishes are present; otherwise, the lake could produce good brook trout fishing. An unusual situation exists at Lobster Lake. When a large volume of water is flowing down the West Branch of the Penobscot River, the flow of Lobster Stream is reversed, so that the natu~al outlet becomes an inlet. When the water level is low in the river, water discharges from the lake outlet in a nonnal manner. Suitable spawning facilities are available for togue repro• duction, and good spawning and·nursery areas are found in the tributaries for salmon reproduction. These inlets should be kept unobstructed to fish migrations. No stocking of hatchery Surveyed - July, 1958 fish is necessary at the present time.
