Fiskevård och delning av fiske vid lantmäteriförrättningar : Studie av FBL 3 kap 8 §
AbstractThis bachelor thesis was performed at the Royal Institute of Technology in Stockholm on behalf of the Land Survey Authority. The thesis is about fish conservation and division of fishing water at official duty. It is the Land Survey Authority that examines division of fisheries, but before a case can be implemented, certain requirements must be achieved such as FBL 3:8, which prevent divisions that are deleterious for fish conservation. The purpose of this thesis is: to obtain a clearer view how FBL 3:8 should be applied in practice, how the application differs between the offices in central Sweden, and how fish care is regulated at both international and national levels.At an international level, in EU the commercial fishery is regulated through the common fisheries policy (CFP). The fisheries policy consists of a reform that will last for 10 years.
Lönsamheten vid nystart av slaktsvinsproduktion : en fallstudie
I have done a case-study about building a new stable for slaughter pigs at a farm close to Kalmar. The farm is able to supply the breeding with cereals and it has enough area to
spread the manure on. The most important factors to gain profit, is the cost for building
the stable, the price of the feeding-stuff and the growth of the pigs. The discount from
the slaughter-house was less important than I thought from the beginning, and it?s a
factor that is hard to influence.
With the new production of slaughter-pig and cattle that already exist on the farm, the
farm will get a well-functioned rotation of crops with lye and autumn rape as
interruption-crop.
Something fishy in Christians : Dietrekonstruktioner genom analys av stabila isotoper på tidigmedeltida skelett från Rambodal, Styrstad Sn, Östergötland
Dietary patterns has varied throughout history, both due to resource and cultural limitations. In this thesis, a study was conducted to establish the dietary patterns of eight individuals from an early Midieaval gravesite in Rambodal, Östergötland, in order to explain why they were buried there. This was done through stable isotope analysis on collagen extracted from bone and tooth on the buried individuals. The analysis showed that these indviduals had a diet that was mainly based on freshwater fish. This suggests that these people may have been christians, due to the fact that fish was not regarded as meat and therefore you did not have to abstain from it during periods of fasting.
Aspects on cow traffic and management on farms with automatic milking
This thesis consists of four case studies. The objective is to find out how to get a well functioning cow traffic in an automatic milking system. Different technical and building solutions are analysed and some adjustments are proposed for the DeLaval herd management software.
Case study 1: Lactation chart comparison from traditional cow traffic and Feed First? cow traffic
Case study 2: Farm A - a study of the precedence passage and the cow traffic
Case study 3: Farm B ? an overview of the farm and their way of working
Case study 4: Key factors ? how can we judge how well a VMS farm is working?
Case study 1: Lactation chart comparison from traditional cow traffic and Feed First? cow traffic
In this survey data is analysed from before and after rebuilding to Feed First? cow traffic. Lactation
graphs are compared between traditional cow traffic and Feed First? cow traffic.
Pre-spawning habitat selection of subarctic brown trout (Salmo trutta L.) in the river Vindelälven, Sweden
Habitat selection of migratory brown trout at the upper reaches of River Vindelälven, wasstudied in September during the pre-spawning period. The fish migrate from down- orupriver lakes for spawning in the river and data was collected by habitat mapping andradio-telemetry. Habitat selection of fish was analysed with preference curves andstatistical modelling, using the physical variables; depth, stream velocity and streambedsubstrate. Preference curves were derived by comparing fish habitat use with their nearbyavailable environment while the statistical modelling aimed to answer three main questions.1) Do the trout have a specific preference of depth, water velocity and streambed substrate?2) Is there any difference in habitat selection between sexes? 3) Is there a shift in habitatselection over time? The preference curves indicated that trout favored water depths of 1-2m, velocity compositions characterized as glides (c.
En ekonomisk hållbar växtodling i sörmländsk mellanbygd :
We have been looking at three different types of agriculture in Södermanland, in the middle
east of Sweden. We call the different types for Intensive, Extensive and Mix. The purpose is
to get an economic defensible plan for how to run different farm sizes. We also have been
looking at the working hours and how many hours the different types will give.
We have a farm called Taxinge Gods as our pilot farm. Taxinge Gods grow 407 ha land and is
located 60 km southwest from Stockholm.
Gårdsbutiken : att välja marknadsföringsstrategi
The agriculture of today is getting larger and larger and it demands more efficient machines to handle these larger units. But all farmers don?t have the opportunities or don?t want to expand. What should they do if they want to remain on the farm? An alternative is to start a farm shop.
Fallstudie på växtodlingsgård :
This report will point out the income for a scania plant production farm, this has been
estimated through a case study. The outcome of this report will later be used to
calculate a reasonable leasehold charge.
This case study is solitary based upon this particular studied farm, at this very point,
and can therefore not be used as a general guide. The reason why this particular scania
plant production farm has been selected, is because the author is born and raised at the
farm and has the intention to run the farm in the future.
The chosen farm for this report is based in the southwest of scania and cover 300
hectare of plant production. The crop rotation consists of autumn wheat, sugar beats,
spring wheat, spring barely, winter rape and fallow. The farm owns all machinery
required.
Vandring av vårlekande fisk och jämförelse av fångst mellan ryssja och strömöversiktsnät i Hammerstaån, Stockholms län
During the last two hundred years many wetlands and streams in Sweden have been lowered to provide land for agriculture and forestry. Some of the coastal wetlands and streams probably served as spawning sites for certain species of fish in the Baltic Sea, but the present situation is not well known. As standardized methods to monitor fish in running waters are carried out during late summer or autumn, there is a need for methods to sample spring-spawning fish in these streams.The aim of this study was to survey the lower kilometer stretch of Hammerstaån in Stockholm, to investigate the extent to which the stream is used by spring-spawning fish. Furthermore, the study aims to evaluate a new type of survey fishing gill net called strömöversiktsnät (SÖN). This was done by comparing the catch of fish by SÖN with that of fyke nets.
Konsumentbeteende vid köp av färsk fisk : en kvalitativ studie för utveckling av ett produktkoncept hos ICA
Health and convenience trends dominate the food industry and retailing business of today.
The health consciousness is spreading while appealing product attributes concerning taste and
packaging also are increasingly important. At the same time, the competition is growing fierce
in the Swedish market with hard discount formats and niche concepts who also are trying to
provide the market with perishables. Therefore, the pressure to lower prices is increasing
making economies of scale and rationalization progressively more important.
In 2004, ICA launched private label meat packaged in a modified atmosphere. Consequently,
many stores went from in-store cutting-up and packaging to selling centrally packaged and
distributed meat. ICA is now developing a concept with fresh fish in modified atmosphere
packages and needs to increase the knowledge about the market and the consumer.
Uppvämningssystem med biobränsle : en fallstudie på Malmviks gård
The use of bio fuel is increasing every year. Nowadays you will find different alternatives to oil and electricity heating system. In this essay I have examined what the economic conditions are to invest in a bio fuel furnace. I have chosen to assume from a specific farm and do a case study on this farm. Malmvik farm is located just outside of Stockholm.
Förluster av nedströmsvandrande fisk vid turbinpassage : En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften
The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.
What factors correlates with the use of game meat, wild fish, berries and mushroom in Swedish households : urban vs. rural areas
This study was made to see too what extent Swedes uses consumptive resources such as berries and mushrooms, game meat and meat from fish in their household on a yearly basis. I have also looked into the difference between rural and urban areas in Sweden. Further aim was to determine what factors that correlates with the participation in berry and mushroom picking and the use of game and fish meat within the household. The study was conducted in form of a mail survey that was sent to randomly chosen persons in every municipality in the six northern most counties in Sweden and in the county of Stockholm. In addition a sample was sent to randomly chosen persons on a national level.The results showed there is a difference in use between rural and urban areas in Sweden in all 4 investigated consumptive resources.
Hållbar vattenkraft i Nissan : En förstudie och konsekvensutredning över förutsättningarna för ökade vandringsmöjligheter med nya fiskvägar.
The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.
