Caracterização de piscicultura em tanques-rede, um estudo de caso na barragem Saulo Maia, Areia - Pb

Abstract

The present work aimed to characterize the fish farming in net tanks in a dam in the Saulo Maia dam, in Brejo Paraíba, the same was carried out in the municipality of Areia-PB between the dates of February 10, 2021 to April 12, 2021 (60 days), in the company Nutrilapia, with CNPJ: 31.393.300/0001-01; street: Fazenda Caiana E Ipueira, S/N which is located on the banks of the Saulo Maia dam with coordinates 6°55'49"S, 35°40'44"W. The species used was the Nile tilapia (Oreochromis niloticus), where The food provided is balanced, crumbly and extruded, according to the size of the fish, respecting the granulometry for each stage of life, two structures were compared, one with 48m³ and the other with 108m³, this enabled an analysis of zootechnical indices , enterprise productivity and a comparison between 48m³ and 108m³ tank net structures; after the experimental period it was noted that there was a significant difference between treatments over the months in relation to survival variance, there was no statistical effect, so it was possible to make a comparison between the most used productive structures in the swamp region of Paraíba , being 48m³ and 108m³ net tanks, it was noted that from an economic point of view and taking into account management, cost and environment the 108m³ net tank becomes more viable taking into account the number of animals and final biomass and possible profitability with the sale in kg of these animals.
