✦ Synopsis
In situ Estimation of a Population of Oikopleura longicauda (Appendicularia) by Means of Two Nets of Different Mesh Size
A population of Oikopleura longicauda was sampled daily for 10 days, a period longer than their life cycle, using two nets of different mesh size (53 and 200 Lun) . Analysis of variance revealed that the number of specimens collected by the two nets was not significantly different for individuals larger than 300 ~/n in trunk length. A grand mean regression plotted for log of length versus log of number of specimens indicated that the number of small-sized o. longicauda (<300 ~um), which are not quantitatively sampled by nets, can be estimated from the collections by use of a coefficient of correction.
