| ABSTRACT Nile tilapia (Oreochromis niloticus) is a euryhaline species which, in marine systems, can provide animal protein where fresh water is scarce. As a result, adequate water management to maintain sustainability is essential, and the use of a salt water recirculating system would be an advantage at the present time. In addition, Arthrospira platensis is used in the diet of aquatic organisms, as it is rich in protein. The aim of this study, therefore, was to evaluate the use of A. platensis as a food supplement in the performance of Nile tilapia in a salt water recirculating system. The experimental model included two groups, with four replications. Each crop had a duration of 45 days (control and test), giving a total of 90 days, with the control... |

| ABSTRACT The aim of this study was to evaluate different levels of dietary supplementation with dried Arthrospira platensis meal during the breeding season of the tambatinga hybrid, using zootechnical performance, haematological parameters and percent composition of the fillet, and by measuring the parameters of water quality. Experimental breeding lasted 64 days. The fry, with an initial weight of 3.56 ± 0.02 g, received diets with two levels of supplementation (20 and 40%) and one control (commercial feed, without the addition of A. platensis meal). The water quality parameters over safe limits were total ammonia (NH3), nitrite (NO2-), and nitrate (NO3-), which increased as the level of supplementation increased, but did not cause any mortalities.

| A cianobactéria Spirulina tem sido utilizada há séculos, tendo em vista suas propriedades nutricionais e medicinais. Neste trabalho, objetivou-se analisar os teores de β-caroteno tanto em suplementos alimentares a base de Spirulina comercializados em estabelecimentos de produtos naturais no mercado varejista, quanto em S. platensis cultivada em laboratório. Alguns pigmentos carotenóides possuem atividade de vitamina A e, dentre eles, o β-caroteno é o que apresenta maior atividade biológica. A extração de β-caroteno foi feita com metanol:água (90:10 v/v), seguida de saponificação e partição em n-hexano. As análises cromatográficas foram realizadas em coluna Waters Spherisorb S5 ODS 2 (4,6 x 250 mm), usando metanol:tetrahidrofurano (90:10, v/v) bombeado a 2... |
