“…Similar results were found by Fülber et al (2009), in the second phase of their experiment with the same lineage. In the present work, the Thai lineage also presented a decrease in performance with increasing density.…”

“…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.…”

“…Similar result was found by Fülber et al (2009), evaluating three lineages of tilapia in tanks at densities of 12, 20 and 28 larvae m -3 in the second phase of their experiment. The same authors found greater weight gain for the GIFT lineage at density of 40 larvae m -3 in the first phase of their experiment (31-58 days).…”

“…The Chitralada lineage, known as Thai, was developed in Japan, improved in Thailand and introduced in Brazil in 1996(ZIMMERMANN, 1999. The GIFT (Genetically Improved Farmed Tilapia) lineage, produced in the Philippines, was introduced in Brazil in 2005(FÜLBER et al, 2009). 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).…”

-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 .
