Caracterização do processo de implantação do projeto de cultivo da tilapia Oreochromis niloticus (linhagem chitralada), em tanques-rede no Açude Boqueirão do Cais, Cuité - PB.

Abstract

This study aimed to describe and characterize the process of implementing the project of cuttivation of titapia Oreochmmis niloticus (Chitralada Lineage), the system of tanks-net in the Açude do Boqueirão do Cais, Cuité - PB. The cuttivation and their respective monitoring were conducted from Mar'ch 2007 to Demrnber 2009 with the aim of providing a training program, disseminating infonnation, knowledge. entrepreneurship and technotogy in growing tilapia in tanks-net. The lifting of the demographic profile of the tishermen indicated that, regarding gender, 90% are male and 10% femaie. Most are aged between 31 and 50 years. Manta! status is 40% married, 25% unmarried and 35% other. The schooi is 40% Iiterate, 20% with no schooling and 10% had completed high schooi. As for housing, 75% live in their own home, 10% rented, 10% and 5% transfen'ed to another type. In social organization, 60% of participating organizations and 30% said they participate in unions. As for the Fishing industry, 57,14% use the net as giii net catch. 90% use the tish for trade. Tilapia is the tish of higher commercial value. 37.04% selling live fish. 50% keep the fish in freezer and 85% have heard of ãsh cuiture in tanks—net in 2007 courses were held for technical quaiifications of tishermen, with didactic preparation of handouts, training videos and practice! sessions, aiming to provide tina! design a full course of cultivation techniques of tiiapia in tanks—net Since the beginning of cuitivation there was & systematic management of the crop weekty with biometry and subcultures. From May 2008 to December 2009 in 04 produciíve cydes of tilapia, grew up monossexuados 35 000 fingenings of tilapia Oreodrmmis niloticus, Chitraiada lineage. acquired in Aquacutture Paulo Otávio station, Limoeire — PE. in fish feed was used 38901 bags of ration type extruded, containing 50, 40, 35 and 32% crude protein in different stages of cuitivation. The fish is sold at the market-piece in Cuité and CONAB. The handiing was carried out with the technical expertise, monitoring of physical and chemimi parameters of pond water. The temperature ranged between 28.1 and 17.3 oC. The color of the water remained within the standards set for good productivity. There were marked turbidity in the water cuitivation. Transparency ranged between 56.5 and 35.4 cm. Oxygen dissolved ranged between 8.3 and 2.9 mg/L. aikalinity ranged bem/een 195.0 and 109.9 mg/L. pH ranged between 8.0 and 4.5 pH and arnmonia between 0.30 and 0, 05 mglL. The results revealed the technical feasibiiity of cuitivation of Nile tiiapia (Chihalada lineage) in tanks—net in Açude do Boqueirão do Cais.
