Abundance of the Oithona nana, the prominent copepod in the zooplankton of Butrinti lagoon is presented here. The study was carried on between February and June, 2010, arranged in two temporal samplings: spring (monthly from February to April, 2010) and summer (June, 2010). O. nana was dominant during all the investigated period; other copepods were really scarce, occurred only accidentally. Development stages of O. nana were divided in three groups, the nauplii, the copepodid and adult stages. Variations on the abundance were noted, higher abundance recorded in June. Results of the development stages were discussed in relation with some physico-chemical parameters (temperature, salinity and dissolved oxygen). The quantity increased with increasing of the temperature. The food availability is an important factor controlling the abundance of zooplankton; generally, maximum copepod population density is coupled to the maximum biomass of phytoplankton. Our study continues following a PhD program, aiming a more complete study on species composition, abundance and seasonal variations of zooplankton community in Butrinti. It is also an additional and complementary approach of the long-term monitoring carried on by the Institute of Food Veterinary Security, Tirana, aimed in the assessment of phytoplankton and toxic algae.
