'Good genes as heterozygosity': the major histocompatibility complex and mate choice in Atlantic salmon (Salmo salar).
According to the theory of mate choice based on heterozygosity, mates should choose each other in order to increase the heterozygosity of their offspring. In this study, we tested the 'good genes as heterozygosity' hypothesis of mate choice by documenting the mating patterns of wild Atlantic salmon (Salmo salar) using both major histocompatibility complex (MHC) and microsatellite loci. Specific...
متن کاملAtlantic salmon – Salmo salar
Distribution Th e species’ range encompasses Europe, North America, and Green land (1) (Fig.1). Non-anadromous forms occur in Europe in a few land-locked locations in Norway and Sweden, and throughout the Neva/Lake Ladoga system and Karelia regions of Russia. In North America non-anadromous forms occurred throughout most of the species’ historical range, as far west as Lake Ontario, and remain ...
متن کاملMate choice for major histocompatibility complex genetic divergence as a bet-hedging strategy in the Atlantic salmon (Salmo salar).
Major histocompatibility complex (MHC)-dependent mating preferences have been observed across vertebrate taxa and these preferences are expected to promote offspring disease resistance and ultimately, viability. However, little empirical evidence linking MHC-dependent mate choice and fitness is available, particularly in wild populations. Here, we explore the adaptive potential of previously ob...
متن کاملZygosity at the major histocompatibility class IIB locus predicts susceptibility to Renibacterium salmoninarum in Atlantic salmon (Salmo salar L.).
Major histocompatibility (MH) class II genes play an important role in the vertebrate immune response. Here, we investigate the relationship between Atlantic salmon (Salmo salar) MH class IIB zygosity and susceptibility to Renibacterium salmoninarum, the causal agent of bacterial kidney disease. By combining DNA sequences from the salmon MH class IIB gene with quantitative ELISA data on R. salm...
متن کاملControl of sea lice on farmed Atlantic salmon S. salar L. with the oral treatment Emamectin benzoate (SLICE)
The use of orally administered emamectin benzoate (SLICE) to control sea lice was assessed for all stock on two salmon farms. Contrasting treatment regimes were used with two oral treatments in farm E in the second production year and one oral treatment in farm L with follow up with bath treatments. Emamectin benzoate surface coated on feed was administered as 50 ug kg1 fish biomass day-1 over ...
