  1. 1. Parentage Assignment using genetic markers in the common carp (Cyprinus carpio)

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Sven Kristian Feddersen; [2023]
    Keywords : single nucleotide polymorphism; Parentage Assignment; aquaculture; genetic markers;

    Abstract : This study investigated the effect of varying single nucleotide polymorphisms (SNPs) marker density, error threshold selection, and different SNP selection strategies on parentage assignment accuracy in carp populations. Using a marker set of 15,615 SNPs, we found a positive correlation between the quantity of SNP markers and the accuracy of parentage assignments, consistent with existing literature. READ MORE

  3. 2. Spatial and temporal variations in stable isotope signatures (δ13C and δ15N) of the gammarids and the common carp in the southern coast of the Caspian Sea

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Nazila Hajizadeh Koupayeh; [2020]
    Keywords : carbon stable isotope; Caspian sea; Cyprinus carpio; food webs; Gammarus aequicauda; nitrogen stable isotope; Pontogammarus maeoticus;

    Abstract : Despite the growing body of research on the use of stable isotope analysis in food web studies, spatial and temporal variations in stable isotope ratios of coastal communities are still poorly understood. The aim of my study is to explore how carbon and nitrogen stable isotopes of selected benthic communities vary spatially and temporally across the south of Caspian Sea. READ MORE

  4. 3. Changes in the fish community in Lake Tåkern, Sweden - a comparison between 1978-1979 and 2019

    University essay from Linköpings universitet/Biologi

    Author : Manfred Skog; [2020]
    Keywords : Fish community; Shallow lakes; Test-fishing; Establishment of species; Crucian carp; Bream; Winter hypoxia;

    Abstract : Climate changes alter species composition in both aquatic and terrestrial ecosystems. For establishment of species in a fish community, dispersal barriers, habitat structure and interactions between species act as a filter. READ MORE

  5. 4. Risk Assessment of Three Herbicides Used in Rice Field in Californian Watersheds on Freshwater Fishes

    University essay from Sektionen för ekonomi och teknik (SET)

    Author : Wan HU; [2012]
    Keywords : ;

    Abstract :   Molinate, glyphosate and thiobencarb are three commonly used herbicides in rice fields. The purpose of this study is using the exposure:effect ratio (RQ value) to quantify the risk of these herbicides to fish in some Californian watersheds. The risk assessment process follows the framework suggested by US-EPA. READ MORE
