In the last week, Phillip J. Haubrock (ESR7) began his sampling efforts for his study of the trophic web and the effect of further species introductions for the control of crayfish in the protected natural lake “Arréo” as part of his secondment at ECOHYDROS in Cantabria, Spain.
He accompanied Alberto Criado and Jose Manuel Gomez, hoping to assist with their work on the eradication of the present invasive species: Common carp (Cyprinus carpio), Black bass (Micropterus salmoides), Pumpkinseed (Lepomis gibbosus) and Louisiana Red Swamp crayfish (Procambarus clarkii). Specimens needed for his research were also collected and will be processed at ECOHYDROS. Phillip Haubrock will combine stable isotope analysis with different dietary analysis methods of present invasive species and a currently not present but to this lake originally native species, which will be potentially reintroduced and stocked to control crayfish. With his approach, he aims at modelling the effect on the trophic web and the effectiveness of this potentially introduced biological control on the abundance of crayfish.
Phillip said: “I am really thankful for this opportunity and the help I am receiving from everybody at ECOHYDROS. Seeing Lake Arreo, which presented itself as an impressive fishery of Lepomis gibbosus, was a great experience altogether and I hope that my work will help protect this ecosystem.”
