A comparison of two extractors for separating meiobenthic nematodes from fine-grained sediments

Abstract

Two methods for the quantitative extraction of meiobenthic nematodes from fine-grained sediments were investigated and compared: (i) Oostenbrink-sugar flotation and (ii) Ludox flotation. The results show that Ludox flotation yielded between approximately 200 and 700% morenematodes. A conversion graph for nematode numbers of the two extracting methods was compiled
