Research on the biology, ecology and biodiversity of mesozooplankton assemblages in the Bahía Blanca estuary date back to approximately 30 years ago, giving rise to a large database of accumulated information (Guerrero et al. 1976; Hoffmeyer 1983, 1986, 1990, 1994; Mianzan and Sabatini 1985; Sabatini 1988, 1989, 1990; Hoffmeyer and Prado Figueroa 1997; Hoffmeyer and Torres 2001; Piccolo and Hoffmeyer 2004). More studies have been carried out on zooplankton from the Main Channel and the inner zone of the Bahía Blanca estuary than from the outer zone. The inner zone is the area that has suffered most modification as a consequence of a combination of anthropogenic pressures including those of an industrial nature (oil refineries, petrochemical industries) and those related to domestic sewage, dredging and maritime traffic. This chapter provides information on the state of the mesozooplankton assemblages in the Bahía Blanca estuary and the changes that have occurred over the last decades.
