Reproduktion och odling av ål

SammanfattningSyftet med den här litteraturstudien var att ta reda på vad det finns för möjligheter och svårigheter att producera ål i fångenskap. Med nya hållbara metoder att föda upp konsumtionsål skulle utfiskningen av glasålar minska i världen och man skulle kunna fortsätta äta den goda rökta ålen med gott samvete.Det finns välutvecklade metoder för att inducera könsmognad hos han- och honålar. Detta utförs genom att injicera hormoner och man kan därför fråga sig om det är hållbart i en produktion för framtiden. Efter kläckning av larverna finns flera viktiga faktorer att ta ställning till, så som utfodring och optimal hållning av ålarna. Även ägg- och mjölkekvaliteten spelar en stor roll när det gäller att hålla ålarna vid liv.Abstract The aim with this study was to find out how far we have come to develop Reproduction strategies in eel culturing.

Side effects of biological control agents in agriculture : does the bacteria Bacillus amyloliquefaciens affect the earthworm Aporrectodea longa?

Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.

Abdominellt ultraljud av vuxna nötkreatur : en praktisk guide

Ultrasound is a diagnostic aid often overlooked by the veterinary practicioner who works with farm-animals. However, it?s use increases, particulary for breeders where ultrasound has long been used to evaluate ovaries and to diagnose pregnancy or disturbances in Reproduction. There is much knowledge in how to examine ovaries and uterus by transrectal ultrasound, but when it comes to doing ultrasound of other organs in the abdomen the knowledge is more limited. Cows are very large animals, so it is not possible to examine everything inside the abdomen with ultrasound, simply because the ultrasound beam has a limited penetration. There is also lots of gas inside the gastro-intestinal tract of a cow, mainly in the large intestine and the rumen, and that makes it impossible to examine the organs behind the gas since the ultrasound waves are reflected when reaching the soft tissue-gas interface.

Flodpärlmusslans status i Laxtjärnbäcken : Effekter på flodpärlmusslan av sedimentbelastning och förekomst av bäckröding

The aim of this present study was to determine and evaluate whether the presence of brooktrout (Salvelinus fontinalis) and sediment load may be a threat against the Reproduction anddistribution of freshwater pearl mussel (Margaritifera margaritifera) in a creek located innorthern Sweden. Freshwater pearl mussel is an endangered species and is dependent ofbrown trout (Salmo trutta) to reproduce. Therefore there are concerns of indirect effects onthe population of pearl mussel by competition between brown trout and brook trout. Ditchesfrom a nearby gravel road have been fixed to lower the sediment load into the creek. I tried toevaluate this action plan.

En skildring av hur tredje världen framställs inom ett urval av västerländsk barnlitteratur utifrån en postkolonial teori : En kvalitativ textanalys

In recent years, the characterization of the Third World and its inhabitants in West-originated children?s books has been subject to debate. Media attention around a selection of books has generated discussions on how this relates and aligns with Sweden?s national teaching curriculum. The objective of this study is to explore how a selection of authors, born in Western countries, have characterized and presented the Third World and its inhabitants in its literature.

Mjölkureahalten som mått på vommikrobernas kväveförsörjning och kons miljöbelastning

The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the Reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.
