| Abstract |
A simple plankton sampler s described which avoids the drawback of clogging of nets. It is used in shallow waters of ponds during studies on productivity. Another type of plankton sampler made of a narrow net is also dipicted, the features of which are also intended to avoid clogging. It is used under the same conditions and gives comparable results to the first device. Then, two methods are proposed for splitting plankton samples not large enough for using the commercially available plankton-splitters. Lastly, a small quantitative dredge for benthic organisms to be used in shallow ponds or littoral waters, is described. |
