Abstract: Zooplankton may be regarded as a sensitive tool for monitoring environmental variations in coastal lagoons due to their ability to immediately react to changes in the water column trophic features and salinity levels. As a coastal lagoon with a broad history of anthropic influence, Rodrigo de Freitas Lagoon (Rio de Janeiro, Brazil) is widely used for water sports and artisanal fishing. The present study aimed to expand the knowledge base about zooplankton in the Rodrigo de Freitas Lagoon by assessing the compo… Show more

“…Asimismo, suelen tener elevada productividad y constituir reservorios importantes de diversidad biológica en comunidades de vertebrados e invertebrados como el zooplancton (Souza et al 2011). El zooplancton incluye organismos que forman parte de esta comunidad solo durante una fase de su ciclo vital (meroplancton), como son las formas larvarias de crustáceos, moluscos y otras especies de invertebrados que ingresan al sistema lagunar-estuarino buscando protección hasta llegar a etapas más avanzadas de su desarrollo.…”

“…Similarly, a significant decrease in zooplankton density with an increase in salinity was also reported in many brackish water systems in Canada and Denmark (Hammer, 1993;Jeppesen et al, 1994). In addition, in the studies conducted in tropical lagoons, a sudden change in salinity was reported as one of the factors that affect zooplankton communities (Souza et al, 2011). For this reason, sudden changes occurring in Lake Karaboğaz during the periods when it is connected to the sea may have decreased the zooplankton density.…”

“…Zooplankton communities in coastal lagoons have major importance for the food web structure and ecosystem health. Zooplankton plays a significant role as the major link in the local trophic food chain, carrying the energy from bacteria/phytoplankton to other invertebrates and fish (Souza et al, 2011). The structure of plankton communities in any coastal water body is also important for commercial fisheries (Ramdani et al, 2009).…”

“…The amount of oxygen depends greatly on the temperature of the water. According to Souza et al (2011), when the water temperature both at surface and at the bottom was high, the oxygen at surface was low and salinity was around 13, evidencing less exchange with the sea. Loureiro et al (2001), between June 2006 and March 2007 it was conducted a dredging operation about 2 km long and 100 m wide at the Rodrigo de Freitas Lagoon.…”

“…Systems can alternate between supersaturated conditions during daylight hours due to photosynthesis and undersaturated at night due to respiration ((NEWTON;MUDGE, 2005). According to Souza et al (2011) Souza et al (2011) the lack of lagoon-sea water exchange, accelerates the accumulation of organic matter, which under high water temperature and consumption of dissolved oxygen reinforces the activity of sulphate-reducing bacteria (SRB) and releases sulphidric gas (H2S) to the water column (DOMINGOS et al, 2012); and implies in adverse conditions to fish species and eventually causes their death. The concentration of dissolved oxygen in the surface varied from 3.7 to 5.6 mg L -1 between 1995 and 1997 and from 1.7 to 2.7 mg L -1 in 2006, considered critical periods with the lowest indices of fish richness and diversity.…”
