Topographyc survey for achieving a recreation sport fishing basin [articol]

Abstract

The paper show a topographic survey carried out for the realization of a recreational pool for sport fishing, in order to be registered in the land book of Pecica city. The land is located at the exit of Pecica. The water basin was made by greening and expanding an old existing water basin. The water basin is populated with carp and caras. The fish population in the basin has a mixed composition, with dimensions according to age. The basin has a rectangular shape and is located 2m from the outer foot of the dam, so 7m more than the width of the protection zone, 5m imposed by the legislation in force, thus fulfilling the conditions of placement. The recreational basin for sport fishing is populated with an amount of 600kg / year, in accordance with the provisions of the aquaculture production unit, ensuring a feed quantity of 30kg feed / day. This recreational pool for sport fishing is a simple semisystematic arrangement, meaning that the entire production process is carried out in a single basin. For this reason, it is designed so that the depth of the water both ensures the growth, reproduction and wintering of the fish population, without needing any human intervention.
