Several techniques commonly used to remove epiphytes from seagrasses were tested on the same Posidonia oceanica (L.) Delile material: shaking, scraping, sonicating and soaking in acid. The effects of each treatment on the epiphyte removal rate and on the seagrass itself were assessed by scanning electron microscopy. The advantages and disadvantages of each technique are discussed. It appears that the combination of an acid treatment with moderate scraping provides the best results as nearly all epiphytes are removed without seriously damaging the leaf substratum.
