EFEITO DAS ALTAS DENSIDADES DE ESTOCAGEM NO CRESCIMENTO E SOBREVIVÊNCIA DE Litopenaeus vannamei NA FASE FINAL DE ENGORDA, CULTIVADOS EM SISTEMAS DE BIOFLOCOS (BFT)

Abstract: RESUMOO objetivo deste estudo foi avaliar o efeito de altas densidades de estocagem na sobrevivência, crescimento e na taxa de conversão alimentar de camarões Litopenaeus vannamei, na fase final de engorda em sistema de Biofloc Technology (BFT), mantendo os mesmos parâmetros de água para todos os tratamentos. Os camarões (11,96 ± 1,14g) foram estocados em microcosmos (tanques de 0,50 m 2 ), conectados a um raceway de cultivo BFT. O experimento teve duração de 45 dias. Os camarões foram estocados nas densidades… Show more

“…The lipid content was lower than the observed by Maicá et al (2012) and higher than the results obtained by Wasielesky et al (2006). The lipid seems to be the component that shows more variations in their values according to the studies published in this regard (Crab et al 2010;Silva et al 2013b). Nutritional studies with L. vannamei indicated that the lipid requirement ranges from 10-12 % (Zhang et al 2013), and these levels significantly tune the growth and enhance the immune abilities.…”

“…The higher ash content in BL treatment could be related to the higher amount of shrimp fecal matter in suspension in tanks with this type of aerator. Similar values were recorder by other authors using the same diffused aeration system (Wasielesky et al 2006;Maicá et al 2012;2013b).…”

“…As discussed by other authors, the present study also demonstrates that when increasing stocking densities, shrimp growth was negatively affected, as observed in the T600 treatment. As such, this may suggest problems stemming from shrimp behavior (Esparza‐Leal, Ponce‐Palafox, Valenzuela‐Quiñónez, Arredondo‐Figueroa, & García‐Ulloa Gómez, 2010; Márquez, Andreatta, Vinatea, Olivera, & Brito, 2012; Silva et al, 2013). Nevertheless, the substrate may have presented benefits until it reached a certain biomass because of the reduction of the relative stocking density after which its benefits could be masked or decreased.…”

“…Krumenauer et al (2011) demostraram que a uma densidade de 300 camarões/m² apresentou melhor desempenho zootécnico na fase de engorda de L. vannamei. Já Silva et al (2013) recomendaram uma faixa entre 292,8 a 337,9 camarões/m² e observou-se que mesmo se a qualidade de água for mantida igual, há efeito negativo entre densidade e crescimento dos camarões, indicando que esse efeito possa ser comportamental. Já Preto et al (2005), determinaram que na fase de berçário de F. paulensis podem ser estocados até 400 pós-larvas/m².…”

“…Esta tecnologia ganhou atenção recentemente como um método de aquicultura sustentável que controla a qualidade da água (Avnimelech, 2015;Ahmad et al, 2017). O uso deste sistema na produção de camarão marinho tem sido extensivamente estudado (Emerenciano et al 2011(Emerenciano et al , 2013Ray et al 2011;Silva et al 2013;Schveitzer et al 2013;Souza et al, 2014).…”
