- Abstract
Fish farming in the state of Rondônia is characterized by adopting, in the great majority, the nurseries excavated without geomembrane. The effect of high stocking densities and leftover rations with a high nutrient content are decisive factors for the deterioration of the quality of the cultivation environment, as well as factors that trigger diseases that disperse rapidly in the environment due to water eutrophication. The objective was the chemical analysis of the levels of organic carbon and organic matter in the sediment of excavated ponds used in the creation of tambaqui fry (Colossoma macropomum). The study was carried out at the Vale do Rio Machado fish farm, located on line 20, BR sector of the rural area of the municipality of Presidente Médici, Rondônia. The sediment samples were collected with the aid of a simple collector in six nursery of fingerlings (V01, V02, V03, V04, V12 and V13) considering a depth of 0 to 20 cm, at three points inside the nursery (triplicate): close at the water inlet, in the middle of the pond and close to the water outlet, with the exception of the ponds 01 and 02, since they are concentrated in the same point the entrance and exit, as well as the entrance and the middle of the pond, respectively. The dynamics of organic carbon and organic matter present in the sediment is directly linked to the flow of water in the nurseries.
