Résumé :
|
A simple rotary sampler, capable of quantitatively harvesting submerged aquatic macrophytes is described. The sampler can be operated from a boat and consists of a central rod with a specially designed cutting blade at the base, and collecting hooks to catch the cut material. The values obtained with this sampler were not significantly different (at the 95% level of probabality) from those obtained by manual cutting underwater. The rotary sampler has great advantages in terms of time, ease of positioning, and effort over hand cutting.
