- Abstract
- Materials and Methods: Trochophores, obtained through artificial fertilization, were reared at 20degrees and 25degreesC and fed with three species of planktonic unicellular algae, Pavlova lutheri Droop, Isochrysis galbana Parke and Tetraselmis suecica Kylin Butcher, until the three setigers metatrochopore stage was achieved. Periodical measurements of larvae collected from the different groups allowed us to determine different growth rates, Then, competent larvae were added to replicate Petri dishes, previously subjected to different biofilm treatment (Sea Water Biofilm and Algal Biofilm), in order to check their settlement behaviour. The same land of substrata treatment were utilised in a settlement test to asses the efficacy of experimental antifouling booster biocide. (literal)
- Background and Purpose: Aim of this work was to use the different stages of Hydroides elegans life-cycle for toxicity and settlement tests. In this perspective the influence of some cultural parameters (temperature and food) on larval growth and the importance of a substrate pre-treatment for the settlement of competent larvae (metatrochophores) have been investigated.
