“…The GIFT lineage presented a total length greater than the Thai when subjected to diets with different levels of crude protein, however, the total length for GIFT and Thai was similar with densities of 30, 40 and 50 larvae m -3 , results that were similar to those found by Fülber et al (2010) and Fülber et al (2009). The greater biomass found in the GIFT lineage is an important advantage, since according to Tachibana et al (2008), it may provide higher profits.…”

“…Although some lineages present better performance, the acquisition of these lineages by a producer does not ensure him a good yield, which can be influenced by the conditions of cultivation, such as the storage density (FÜLBER et al, 2010). The tilapia genetic variability may be high, requiring a proper reproductive management to avoid the negative consequences of inbreeding, i.e., a drop in the expected yield (MOREIRA et al, 2007).…”

“…The Thai lineage has been the most cultivated and has been well accepted by Brazilian producers (TENÓRIO et al, 2012) because its high genetic potential (LUPCHINSKI JÚNIOR et al, 2008) and productive performance (BOSCOLO et al, 2001). The GIFT lineage has a higher yield potential compared to the Thai and Bouaké lineage (FÜLBER et al, 2010), indicating that the performance potential of the different lineages of tilapia is related to genetic factors (FÜLBER et al, 2010). However, regional researches evaluating their performance at different conditions of cultivation are needed, since some studies have shown the interaction between lineage and environment (EKNATH et al, 2007).…”

-Larvae from two Nile tilapia (Oreochromis niloticus) lineages were subjected to different storage densities. An experiment was conducted arranged in a 4 x 2 factorial scheme, four storage densities (6.25, 12.50, 18.75 and 25.00 larvae L -1 ) and two lineages (GIFT and Thai). Larvae from the lineage GIFT and Thai (4,000) were distributed in 32 aquariums with 8 liters of water each, in a randomized order with four replications. The larvae were maintained in the aquariums with constant aeration and natural photoperiod for 36 days. Limnological variables were within the proper range to the specie. Data were subjected to ANOVA, and the Tukey test was used for the density effects. Regarding the biological variables, there was no interaction between lineage and density. The GIFT lineage presented better performance on total length and biomass at the 36 th day. Regarding the densities of each lineage, the greater length, weight and weight gain results were found with a density of 6.25 larvae L -1 , however, an increase in biomass and a space use optimization occurs using 25 larvae L -1 . Therefore, the lineage GIFT at density of 25.00 larvae L -1 is indicated for larval culture.Keywords: GIFT. Oreochromis niloticus. Lineage selection. Thai. LINHAGENS DE TILÁPIAS DO NILO SUBMETIDAS À DIFERENTES DENSIDADES DE ESTOCAGEM NA LARVICULTURA RESUMO -Larvas de duas linhagens de tilápias do Nilo (Oreochromis niloticus)foram submetidas a diferentes densidades de estocagem. O ensaio foi conduzindo em um fatorial 2 x 4, sendo quatro densidades de estocagem (6,25; 12,50; 18,75 e 25,00 ind. L -1 ), e duas linhagens (GIFT e Tailandesa). Larvas irmãs das linhagens Tailandesa e GIFT (4.000 ind.), foram distribuídas em 32 aquários com 8 L de água cada, de modo casualizado com quatro repetições cada. Por um período de 36 dias, as larvas foram mantidas em aquários providos de aeração constante e fotoperíodo natural. As variáveis limnológicas estiveram dentro da faixa adequada à espécie. Os dados foram interpretados por meio de ANOVA e para os efeitos densidade, utilizou-se Teste de Tukey. Quanto às variáveis biológicas, não houve interação entre linhagem e densidade. A linhagem GIFT apresentou melhor desempenho em comprimento total e biomassa para o 36 o dia. Dentre as densidades para cada linhagem os melhores resultados de comprimentos, peso e ganho de peso, foram para a densidade 6,25 ind. L -1 , mas ao se utilizar 25 ind. L -1 ocorre aumento na biomassa e otimização do espaço utilizado. Portanto, indica-se as linhagens GIFT na densidade de 25,00 ind. L -1 .

“…The best performance of GIFT tilapia was reported by Fülber et al (2010) when evaluating the productive performance of Bouaké, Chitralada, and GIFT strains at different rearing stages, densities, and protein levels in northern Paraná, and found significant differences in final weight between strains. Similarly, Vieira et al (2005) evaluated Chitralada (UEM/Codopar), Supreme (Aquaculture Aquabel), Bouaké (UEM/Codapar), and Chitralada (Aquabel) and showed that the Supreme strain was superior to the others in both phases.…”

Therefore, there is a need to compare species or strains and evaluate critical factors.…”

This study aimed to compare the morphological traits and growth performance of monosex populations of the Genetic Improved Farmed Tilapia (GIFT) and Saint Peter ® of male tilapias reared in a mixed system. The experiment was carried out from June 2012 to November 2012 in Sgarbi fish farm, Palotina, Paraná State, Brazil. GIFT juveniles were obtained from the State University of Maringá (UEM/Codapar) fish farm broodstock, and the red hybrids were from the Sgarbi fish farm broodstock. The average genetic values of GIFT from three genetic groups (I, II, and III) were obtained by controlling individual pedigree and genetic evaluation using Best Linear Unbiased Prediction (BLUP). Information from complete GIFT pedigree since its introduction in Brazil was used, and the genetic groups were ranked as I (upper group), II (middle group), and III (inferior group). In all, 1,880 fish, including 480 GIFT strain and 1,400 red hybrids, with an average initial weight of 15 g, were placed in a semi-intensive system with a density of 4.7 fish m -2 . The fish were individually identified using Passive Integrated Transponder (PIT) tags. Harvesting was performed at the end of a 160 d period. The performance data including final weight and daily weight gain, and morphological traits including total length, standard length, body depth, head length, tail depth, tail width, body width, head length/standard length, body area and body volume were evaluated. Analysis of variance (ANOVA) and the Tukey test at 5% probability level were applied. The average final weight and daily weight gain among the three genetic groups of GIFT did not show significant differences. However all GIFT groups (I, II, and III) presented average values of performance and morphological traits higher that the Saint Peter ® . Among the GIFT genetic groups, only body depth between groups I and III showed significant differences (p<0.001). The morphological traits and growth performance are superior in the GIFT strain, regardless of its genetic group, when compared to Saint Peter ® , except for the head length/standard length ratio.
