title: [Action of a molluscacide (Bayluscide-SRB) from the Dynatech R/D Company in lakes of northeastern Brazil--Sergipe, Brazil].
abstract: To study the action of molluscicide nine ponds were selected: 3 of them lying in Maruim municipality, 29 km far from north Aracaju, the State capital, and 6 ponds in Itabaianinha municipality, 118 km far from south Aracaju. This study was carried out for 16 months. Environmental parameters observed were those thought to have any influence on the planorbids and/or the molluscicide: water temperature, transparence, salinity, pH, dissolved oxygen, CO2, and the nutrients-phosphorus, nitrogen, potassium and calcium. Plancton microorganisms were also considered to observe Bayluscide action on them. SRB was used in a concentration of 6.25 kg per 1.000 m3 water, to achieve 1.0 ppm Bayluscide concentration according to the producer's instruction in Massachussett-USA.
