This essays aim is to investigate the possibilities of subjective interpretation of Lgr11, the Swedish curriculum for elementary school. The assignment that the Swedish authority Skolverket got in 2009, was to create a curriculum that would grant that the students achievements would not be influenced by any subjective opinions and that all elementary schools in Sweden will give an equivalent education. In the Government bill this is a theme throughout the text and the Minister of Education has also claimed that this document will leave very limited space for subjective reading and interpretation. He says that Lgr11, in contrast to the previous curriculim Lpo94, will clarify what the purpose of the different subjects is and on what grounds the assessment of the students should be based.The method used is the literary theories of reader ? response as they are expressed by Literarycriticist Stanley Fish.

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from Fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.

Fisk är ett hälsosamt livsmedel och allt eftersom världsbefolkningen har växt och hälsotrenden blossat upp, har trycket på fiskerinäringen ökat.Bakgrundens fakta tog upp olika konsekvenser som fiskodling kan medföra och hur stor kunskap konsumenten har om detta och deras makt att påverka industrin.Syftet med studien var att belysa brister i fiskodling kopplat till konsumenters kunskap, samt hur de etiska frågorna påverkar konsumentens val.I metod och materialstycket lades det fram att studien var en litteraturstudie som baserades på vetenskapliga artiklar från olika databaser som gick att tillgå vid Örebro universitet.Resultatet av undersökningen gav inblickar i vad konsumenter visste om odlad fisk, vad de tyckte om produkten och hur eller om de utövade sin makt. Resultatet visar även hur hanteringen av fisk går till på fiskodlingar runt om i Europa.I diskussionsavsnittet i studien lades bakgrundsfakta ihop med fakta ur resultatavsnittet. I diskussionen framkom information om att konsumenters uppfattning och kännedom om odlad fisk inte var tillräcklig, trots de märkningar och informationskällor som presenteras i bakgrunden.I diskussionsavsnittet diskuteras även processen som ledde fram till den här studien och vad som fungerat respektive inte fungerat..

In this study the practical work with the EU Water Framework starts on the island of Gotland. 33 lakes and 32 streams have been characterized and classified regarding to their ecological status. The aim with the characterisation is to create a uniform discription of all waterbodies and a comparable estimation for the future. The aim with the classification is both to study the waterbodies ecological status and to gain knowledge of where the resources should be concentrated so that the ecological status in all waterbodies will be good in 2015.The characterisation has been done according to the EU Water Framework Directive, and the factors that have been applied are the mean depth and area of the lake. The length and size on the catchment area are the factors that have been used on streams.

Global catch Fishery is said to been oppressed to its limit (Boyd & Schmittou, 1999), further implying aquaculture might be the only solution to the world demand for Fishery products. The applied term aquaculture in this paper refers to the one used by NOAA (2008); breeding, rearing, and harvesting of plants and animals in all kind of water environments, including but not limited to ponds, rivers, lakes, and the ocean. According to Shamshak & Anderson (2008, p. 74) aquaculture has over the past 20 years been the fastest growing food sector with an average annual growth rate of 8.7%. It further represents approximately 37 % (Shamshak & Anderson, 2008, p.

During the timber floating era, most of Sweden?s watercourses were altered. This decreased the amount of available spawning habitats for salmonids, and hence had a negative effect on the riverine brown trout (Salmo trutta) populations. Reconstruction of spawning grounds is today a common measure in restoration of altered streams in Sweden. However, very little evaluation of the effectiveness of these reconstructed spawning grounds exists.

This thesis presents the results from a osteological analysis and a GIS-study aimed to examinedifferences in the located animal bones in different areas of the excavation site of Ajvde.The osteological material came from five excavated square meters on the site and was comparedwith osteological results from other researchers from different areas to create overview and try tosee differences between the areas.The GIS-study took data from all animal bone material excavated on the site, a total of about 2300kilos, and presented them in maps of spatial distribution for each layer (pictures 4, 5, 6 & appendixpicture 1) to see if there were any clusters of activity and changes between the layers. The dating ofthe culture layer and the burial field (pictures 7 & 8) were presented in maps to see if they could becorrelated with what was seen with the animal bones. Pictures of different shorelines were alsopresented (picture 9) to compare with the results that were seen in the changes of animal bones fromdifferent layers.The results of the GIS-study have shown that the activity on the site have moved over time alongthe hight differences of the land. The earlier layers show activity only on the higher elevation butlater moves down, and in the upper layers activity have been all over the excavated area. Clusters ofanimal bones were seen in the so called ?black areas? of the sites (shown in picture 2) but also otherareas contained a lot of animal bones.The results of the osteological analysis have shown that there are differences in what species arefound in different areas.

During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the Fishing industry. The grey seal destroys and enters Fishing traps and consumes large quantities of the Fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

Freshwater environments are threatened worldwide, of which many of the species associatedwith freshwater. In 2014, 243 freshwater mussels were on the international Red List. One ofthem is the freshwater pearl mussel, Margaritifera margaritifera, which because of itscomplex life cycle can be counted as an indicator of whether a stream is worth protecting. It's since the early 1900's in decline throughout their range. Sweden is counted as a core area which is why we have not only a national but an international responsibility to conserve the species.

The upstream spawning migration of Atlantic salmon (Salmo salar) at the confluence area between the power-station outlet and the bypass-channel in river Umeälven (flow 430 m3s-1) was compared in 2004 and 2005, two years with different experimental flow-regimes. In 2004 the water flow in the bypass-channel was altered during the day with increased flows during the nights while the water flow in 2005 mainly was altered between the weekdays and weekends. Salmon showed altered migratory behaviour in this confluence area, assessed with telemetry (n=116) and echo-sounding, with up- or downstream responses depending on flow-changes in both the bypass and the power station outlet. Increased turbine flow through the power-station generally attracted salmon into the tunnel outlet area while increased spill-flows facilitated salmon to enter the bypass. Echo-sounding in the confluence area showed an increased swimming activity up- and downstream due to time in the day and flow-rates through the tunnel outlet. No changes in activity could be detected due to increasing or decreasing flow through the hydro-power facility.

Exotic small animals that are commonly kept as pets include aquarium Fish, cage and aviary birds, rodents, rabbits (Oryctolagus cuniculus), reptiles and amphibians. These different kinds of animals, even species within the same class, may differ markedly from each other regarding physiology and requirements. Although these species are common in both Swedish households and in pet trade, many animal keepers have a lack of knowledge about the origin and requirements of their pets. This is a cause of several health problems seen in animals which are held in captivity. In Sweden, the county administrative boards perform all animal welfare controls.

In this essay, Neolithic potsherds from Alby, Öland has been examined. The purpose was to investigate the connection between the lipid residues and the vessel shapes and ornament. To solve the attempt lipid and morphological analyses were executed. The lipid analysis revealed traces of different food residues and the morphological method showed various shapes and decors. The result indicates that the Alby ceramics has been used for cooking/storage of different Fish and meat dishes, as well as vegetables and that the vegetables doesn?t derive of cereals..

Most of the sea areas within the European Union are overFished and the catches are estimated to be up to five times lager then the amount to achieve a sustainable Fishery. In doing so, the management of EU's marine resources comes to be questioned. The purpose of this study was to analyze EU's administration of marine Fisheries and to explore which steps that can be undertaken to counteract the negative trend. The questions of the study were: How does the EU administrate today?s marine Fishery recourses? And: How can the problem whit overFishing be discouraged? To answer these questions a comparative analyses were used to compare and evaluate administrative systems.

Abstract The purpose of this work is to investigate children?s perception of Swedish birds. Through qualitative questions there were twelve children interviewed. I showed the pictures for the children of different animals that we discussed but with focus on birds. The children could partly distinguish which of the pictures that represented birds and who did not.
