Cultivo de camarão marinho (litopenaeus vannamei) na Secretaria Executiva de Ressocialização, Ilha de Iitamaracá - PE

Abstract

This report refers to completion of Stage Observed Required in the Supervisão de produção (SUPROD) of the Secretaria executiva de Ressocialização, in the rural area of the ilha de Itamaracá, which developed between October and December 2018, totaling 300 hours. During this period they were made shrimp farming activities in the production, since the restructuring of nurseries for fish removal of shrimps for marketing. The supervisão de produção aims to re-educate and reintroduce in the common society people who have committed some crime and therefore have been removed from the community. The SUPROD has a total area of 1,254 ha for many different agronomic production activities and zootechnical of this total, 11 hectares are dedicated exclusively to the production of marine shrimp in the shrimp farming industry. Only one nursery of 0.9 ha is in full operation, shrimp farming is the most profitable activity of SUPROD. The water supply is carried out by the Santa Cruz Canal by opening the floodgates in the high tide period. The water supply enters through the gate flooding the nurseries. The cultivation system adopted is the single-phase with direct settlement, using post-larvae (pL10) from the commercial laboratory (Aquatec, RN). The post-larvae are fed commercial feed of Camanutri CR2 with 40% crude protein and granulometry of 0.4 -1.0 mm in a period of twenty five days, after which a 6-day transition period of for the pellet feed with 32% crude protein with 2.4 mm granulometry until the end of the culture. At the end of the cultivation cycle, the animals are harvested and marketed to local merchants in the premises of SUPROD itself. The production of the observed cycle was 602.6 kg, mean final weight of 9.5 g, cultivation time of 74 days, feed conversion factor (FCF) of 1.14, survival of 70.18% and average productivity of 2,462.6 kg / ha / year, considering four cycles per year. Due to budgetary and technical difficulties, the farm still presents a very rudimentary form of cultivation, requiring the adoption of more appropriate measures for cultivation, such as: use of inorganic and organic fertilization in the soil, treatment of soil organic matter in the period between cycles, to improve the method of post-larvae acclimatization, monitoring and treatment of nursery water. These suggestions are intended to help reduce economic losses and increase production.
