The distribution of these variables shows two zones of high concentration of particles: one located in the first “third” of the bay and the other in the upper end. High values of chlorophyll <em>a</em> were due to the nannophytoplankton size class, which is the major contributor to the total phytoplankton abundance. The most abundant species of microphytoplankton were <em>Chaetoceros curvisetus</em>, <em>C. lorenzianus</em> <em>C. teres</em>, <em>C. cinctus</em> and <em>Lithodesmiun undulatum</em>. The phytoplanktonic-POM and non-phytoplanktonic-POM contribution estimated at the surface shows that the highest protein percentage (69.5%) was due to phytoplankton, whereas at 10 m depth it corresponded to non-phytoplankton-POM or detritus. This indicates that a high quality POM in the water column represents a potential source of food for the different development stages of <em>A. circularis</em>.</p>}, number={3}, journal={Ciencias Marinas}, author={Martínez-López, A and Gárate-Lizárraga, I}, year={1994}, month={Mar.}, pages={301–320} }
