Acompanhamento e descrição do cultivo intensivo do Litopenaues vannamei na fazenda Expopesca Aquicultura Comercial Ltda

Abstract

This report refers to the activities monitored and carried out by the student during the supervised internship at the farm Expopesca Aquicultura Comercial Ltda., located in the municipality of Cascavel / CE. The main branch of activity of the farm is the intensive growth of marine shrimps (Litopenaeus vannamei) in semi-excavated nurseries, lined by geomembrane and, some, covered with agricultural greenhouses. The water used for the farming is salty, and comes from the catchment through a pump in the estuary of the Rio Choró. The internship was undertaken from July 17 to August 17, 2017, and followed the various activities inherent to the farming, such as handling of level boards and screens of the central drain, preparation and fertilization of nursery tanks and nurseries for fattening, reception of post larvae and settlement of nursery tanks, transfer of animals for the fattening nursery, monitoring and manipulation of water quality, food management, presumptive analyzes, periodic biometrics and harvest. In the growth carried out in a nursery covered with an agricultural greenhouse, an average survival of 78% was reached, final yield of 25.500 kg/ha/cycle, feed conversion factor of 1,55, making it possible to produce shrimps with a final average weight of 13 g. After the internship, it was observed that the cultivation system adopted in the farm has a great potential of shrimp production, demonstrating its viability and showing to be efficient, with high density of production. Also, it was concluded that the internship was relevant in professional and personal growth as a Fisheries Engineer.
