Novel Analyses of Endocirne Disruption in Shore Crabs from UK Estuarine and Coastal Environments - WT06016

Description
The overall approach of this study was to use a combination of morphometric and behavioural analyses to assess possible endocrine disruption in Carcinus maenas.

Three specific objectives were identified:

1) To carry out morphometric measures on field collected crabs to confirm the findings of a preliminary study by Richard Ladle, and to extend the survey to include sites in northwest and southwest England, which have been surveyed previously for endocrine disruption in fish.

3) To investigate if sex pheromone production in ‘super female’ crabs and the behavioural response of inter-sex ‘male’ crabs to female sex pheromone differ from that of ‘morphometrically normal’ crabs.

3.) To investigate if crab steroid moulting hormone titre of 20 hydroxyecdysone of inter-sex and ‘superfemale’ crabs differ from that of morphometrically normal crabs of each sex.
