The macro benthic fauna of rocks and boulders in the lubeck bay western baltic sea investigated from the under water laboratory helgoland

, : The macro benthic fauna of rocks and boulders in the lubeck bay western baltic sea investigated from the under water laboratory helgoland. Helgolaender Wissenschaftliche Meeresuntersuchungen 27(4): 439-449

A diver-operated suction sampler was used to collect the macrobenthic fauna on a rocky bottom Luebeck Bay (western Baltic Sea) from the Underwater Laboratory (UWL) "Helgoland" in Oct. 1974. A comparison of the faunal composition with the angle of inclination of the substrates was the goal. The ascidian Dendrodoa grossularia and the polychaete Polydora ciliata constituted 95.6% of the total number of specimens sampled. The lowest densities of both species occurred on overhanging substrates. Both species appeared to have a heavy settlement during the late summer or autumn. In general, the angle of inclination of the substrate bore little relation to the qualitative composition of the fauna on a rocky bottom in Niendorf Bay, but some of the species (D. grossularia, P. ciliata, Asterias rubens, Diastylis rathkei) were more sparsely distributed on overhanging substrates. The calculated values for Fisher's coefficient of dispersion indicate that the 3 most abundant species (Dendrodoa grossularia, Polydora ciliata, Nereimyra punctata) show some degree of aggregated distribution. Four motile invertebrates, N. punctata, Idotea balthica, D. rathkei and Facelina drummondi were observed swarming in the water. N. punctata and I. balthica were most abundant in samples taken during the daytime, D. rathkei was most abundant in samples obtained during the early part of the survey when water temperatures were higher, while no relation could be found between the occurrence of F. drummondi and the time of day of sampling.
