ABSTRACT

O presente trabalho teve por objetivo cultivar juvenis recentes da lagosta espinhosa Panulirus argusem diferentes temperaturas. Foram utilizados 20 indivíduos com peso e comprimento médio (cefalotórax e total) de 2,680 g, 13,8 mm e 40,4 mm, respectivamente. Os juvenis foram divididos em cinco tratamentos (temperaturas: T24, T26, T28, T30 e T32) com quatro repetições em delineamento inteiramente casualizado. Após 180 dias de cultivo, as variáveis físicoquímicas da água foram similares para todos os tratamentos. Os indivíduos cultivados nos tratamentos T26 e T28 apresentaram as melhores taxas de crescimento em relação às lagostas cultivadas nos T24 e T30, sendo observada diferença estatística significativa (P < 0,05). Os juvenis pertencentes ao tratamento T32 morreram antes de completar ummês de cultivo. Concluiu-se que juvenis recentes de P. argus podem ser cultivados nas temperaturas de 24 °C a 30 °C, sendo constatado maior crescimento a 28 ºC.


The present work aimed to culture early juveniles of spiny lobster Panulirus argus in differenttemperatures. Twenty individuals with mean weight and length (cephalotorax and total) of 2.680 g, 13.8 mm and 40.4 mm, respectively were used. The juveniles were divided in five treatments (temperatures: T24, T26, T28, T30 and T32) with four repetitions in an entirely ramdomized experimental delineation. After 180 days of culture, physico-chemicals variables of water were similar in all treatments. The cultured individuals in T26 and T28 treatments showed the best growth rates in relation to lobster cultured in T24 and T30, being observed significant statistical difference (P < 0.05). Thejuveniles belonging to the treatment T32 died before completed one month of culture. It was concluded that early juveniles of P. argus can be cultured in temperatures of 24 °C to 30 °C, with higher growth at 28 ºC.
