If yes, is there any formula for that? Because usually we do collection of zooplankton samples column wise and not at a particular depth like phytoplankton.

There are plankton nets that allow obtaining depth-stratified zooplankton samples, and methods to count and estimates individual and integrated biomass (see Harris, R., Wiebe, P., Lenz, J., Skjöldal HR y Huntley, M. (eds.) 2000. ICES Zooplankton Methodology Manual. Elsevier.).
Dear Mrunmayi,
we have some methodological recommendations about sampling from the Soviet period (1983), which is attached for you. Look, please, page 67. If you have batometer of Ruttner you can do it even from demersal leyer, but I suppose that you are using Jedi pl net, so can act by catching deeper every next sampling and excluding adjusent depths from the upper layer (you will have the different columns in height (depth):
surface-0,5 m
0,5-2,0 m (c. 0-2)
2-5 (will be catching 0-5)
5-10 (will be catching 0-10)
10-25 etc.
25-50
50-100
After that you will obtaine perfect data for distribution in layes and can even take (make figure) the graphical integral in biomass or production!
This is enough exhaustive but extra effective.

Thanks to all of you for your reply.The suggestions and references given by you all can be helpful for my study.
