Abstract

Abstract

To compare the capture efficiency for Sagitta crassa(chaetognatha) of three types of plankton nets (505 μm meshed coarse net,200 μm meshed WP-2 net and 77 μm meshed fine net),zooplankton samples were collected in central Bohai Sea in November,2012. The fine net outperformed the other two nets,respectively capturing 1.3 and 2.9 times the abundance of the WP-2 net and the coarse net. The coarse net apparently under-sampled less than 9mm long individuals; the WP-2 net under-sampled less than 4 mm long and a fraction of 4-5 mm long individuals; while the fine net appeared to be slightly less efficient when capturing more than 9 mm long individuals. The capture efficiency was closely correlated to the body size of S. crassa: smaller body size caused greater differences in capture efficiency of the nets. As for more than 9mm long individuals,avoidance of S. crassa probably accounted for the slightly lower capture efficiency of the fine net. We recommend that the fine net be employed for sampling S. crassa during reproduction periods to provide supplementary results to other types of nets,thus more reliable data could be obtained for future research of population dynamics.
