and microplankton blooms as causative agents of juvenile oyster disease in Crassostrea virginica (Gmelin).
The organisms also can be classified according to their size as picoplankton (0.2-2 [micro]m), nanoplankton (2.1-20 [micro]m), microplankton (20.1-200 [micro]m), mesoplanktlon (201-2000 [micro]m) and macroplankton (> 2000 [micro]m) [1, 2].
horneri can compete with microplankton, protozoan, and even bacteria for nutrients, inhibiting the harmful algae blooms [4].
(2010) also state that microplankton (ciliates and rotifers) is the most species-rich component of the Baltic Sea zooplankton, yet it lacks continuous attention in environmental studies.
In aquatic systems food chains are often filled with small prey items (pico-, nano-, microplankton, meiophauna, etc.), and many top predators are much larger than those of terrestrial systems.
For the Brazilian coastal zone, these are the first results related to the category of continuous plankton sampling with the use of VOR and microplankton was the fraction with the highest yields in the VOR tows and was also common in the North Sea and North Atlantic Ocean (Lindley & Williams, 1994; Beaugrand et al., 2000; Reid et al., 2003; Richardson et al., 2006).

Specifically, studies of pelagic food webs have shown that an increase in the availability of nutrients in the environment results in an increase in algal production, which leads to a subsequent increase in the number of bacteria, heterotrophic flagellates and microplankton (ciliates, rotifers and bosminids) (AUER et al., 2004; PEREIRA et al., 2005; SIPURA et al., 2005; SAMUELSSON et al., 2006).
Most stations were dominated by microplankton size fraction (Figure 2(b)), with exception of station 27 where picoplankton contributed by more than 80% to Chla.
