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.

The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only Concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.

Background: According to many authorities Trademark consideration will within the companies become all more prioritized objectives for competitive advantage and a strong organisational structure.Trade marking is becoming an important tool, not only Production oriented companies apply this on their products or services whereas it is today spread in many different sectors.Problems: On the basis of theoretical and empirical studies, we will try to see how a trademark is built up.This will guide us to our questions at issue:? How has the actual process for HTF been in order to strengthen and to build up their trademark, how have they achieved this in practice?? What are the underlying criteria?s to for this work and what role has the consultant company BMN in the actual process?Aim: The authors have for intention to create an understanding on why there is interesting for a trade union organisation like HTF to carry out a trademark development investment. A further understanding will be to highlighting a strong trademark's advantages and possible disadvantages.Results: As a trade union organisation where the relationship to the members and the potential members is becoming all more important is the interesting to highlight their trademark clear and in addition to that contribute to building and establishing strong relationships. on the basis of this study we can state that it is now one of the most important support activities that as a trade unions to highlight its core values through trademark. As a trade union, one can to a large extent work with and to apply the market the economic mocks-up for trademark build up.The most important aspect is that we can state , in the future developed to Concentrate more on communication, positioning, segmentation and diversification, which the trademark act as intermediary.

The purpose of this thesis is to analyze how the ongoing controversy surrounding the Internet, the phenomena of digitalization and file sharing will affect the music industry in the form of the ?big five? labels. Furthermore the thesis aims to present a recipe of strategies for the companies? survival by studying their situation through a theoretical perspective in conjunction with a comparative analysis with industries facing the digitalization challenge. The theoretical contribution lies in the strategic perspective at an industry level.

This master thesis project is a part of a project called ?Järboprojektet? at the regional board of forestry, the district of Gästrikland. The project will give answers to questions regarding if an analysis of satellite images can be used to contact and inform landowners of the located areas where precommercial thinning is useful. The whole project is a part of the National Board of Forestrys IT-stake where the analysis of satellite images will, at the latitudes possible, be adapted to each district in purpose to identify these areas in need of precommercial thinning. This master thesis project is based on a field inventory of identified objects where precommercial thinning is useful.

Modern milk production have come a long way when it comes to accommodating the nutritional and physiological needs of the animals, but unfortunately the behavioural and psychological needs of cows and heifers are often left unfulfilled. A long time for eating is beneficial for the digestion and also gives the cattle something to do and decreases the risks for developing abnormal behaviours. An important factor that influences eating- and ruminating time is the particle size of the roughage. The aim of the study was to find out if particle size influences the behaviour of dairy heifers, in particular with regard to eating behaviour and abnormal behaviours. The study was conducted at Uddetorp farm high school in Skara. Forty-two heifers of the breeds SR and SF were housed in 8 slatted floor pens.

Today we have more game species than ever before in our landscape, both regarding number of species and number of individuals. The increasing number of wild species is an increase in game recourse for the countryside. The increase of game species, however, has negative effects on forests and agriculture land. The negative effects for forestry are damages on economic important trees, due to losses in production and quality. However there are ways to decrease the damage on valuable and important trees.

Protecting the environment has with time grown to take a more central role in the society. Agriculture plays an important role in the society since this sector produces our food. More thorough research on how agriculture affects the environment is therefore motivated. This research can be used to improve the agricultural practice from an environmental point of view. This is something that both the farmers and the consumers can profit from. This study aims to form the basis for creating environmental indicators for use of nitrogen and energy on dairy farms. Twenty-three farmers in western Sweden have been interviewed about their farms, both organic and conventional. They produce milk with different intensity, defined as the amount of milk delivered (sold) per hectare of arable land.

This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.

Den teoretiska bakgrunden bygger på de i litteraturen tydliga grundstenarna för andraspråksinlärning, vilka är varierad undervisning, tryggt klassrumsklimat, kulturella variationer, behov och motivation. Dessutom har samtalets betydelse för andraspråksinlärning lyfts fram och huruvida skapande verksamhet bidrar till samtal mellan eleverna. Syftet med studien var att göra en jämförande studie mellan tidigare forskning och verksamma pedagogers uppfattningar angående vilka faktorer som upplevs viktiga vid svenska som andraspråksinlärning. Dessutom ville vi undersöka huruvida skapande verksamhet stimulerar till samtal och om det därmed kan underlätta svenska som andraspråksinlärning. Studien grundade sig på intervjuer som gjordes i en grundskola för yngre åldrar i ett mångkulturellt område.
