| Sumario: | The material analysed here is part of a collection made with a 91 van Dorn bottle in a 5 m depth station at Ubatuba - São Paulo, between June 1976 and May 1977. Two sets of general linear models were constructed, one for the winter months (June, July and August) and the other for the summer ones (December, January and February). In each set, copepodid stages and adults were studied separately, in relation to hour of sampling, depth, interaction hour-depth, and environmental factors (light penetration, dissolved oxygen, salinity and temperature, considered as a whole). All the stages studied were spread in the water column and show no vertical migration. The hour was not significant for any stage except for copepodid V female in winter. This results agree with a previous analysis of the same material performed with the data of each two months throughout the year (Milstein, 1978).
