A bioassay of antifouling treatments is being developed based on the settlement and metamorphosis of bryozoan (moss animal) larvae.
In order to broaden the taxonomic range of testing used to assess new antifouling formulations, a bioassay using the responses of bryozoan larvae is being developed. Test surfaces are assessed both in terms of the willingness of larvae to settle, and the strength of adhesion of the ancestrula (the first zooid of the potential new bryozoan colony) that develops following settlement. The project is in its second round of funding and results are very promising.
