| The lectins, proteins which specifically recognize carbohydrate moieties, have been extensively studied in many biochemical and structural aspects in order to establish the molecular basis of this non-catalytic event. On the other hand, their clinical and agricultural potentials have been growing fast. Although lectins, mainly those from legume plants, had been investigated for biological properties, studies about the physiological functions of lectins are scarce in literature. Therefore, despite the accumulated data on lectins (as proteins), the role played by these signalizing molecules is poorly discussed. In the light of our accumulated results on legume lectins, specially those obtained from plants belonging to the Diocleinae sub-tribe and available... |

| O objetivo deste trabalho foi avaliar o potencial de 32 espécies de algas marinhas das divisões Chlorophyta, Rhodophyta e Phaeophyta como fontes de α- e β-caroteno e α-tocoferol. Todas as clorofíceas analisadas apresentaram α- e β-caroteno. Os teores máximo e mínimo de α-caroteno foram detectados nas espécies do gênero Caulerpa e em Codium decorticatum, respectivamente; e β-caroteno foi mais baixo em Caulerpa mexicana e mais elevado em Ulva fasciata. Dentre as rodofíceas, 11 espécies apresentaram α-caroteno, com máximo em Botryocladia occidentalis. β-caroteno foi encontrado em todas as algas vermelhas analisadas com teores mínimo e máximo em Gracilaria caudata e Bryothamnion triquetrum, respectivamente. As feofíceas apresentaram apenas β-caroteno, com... |

| 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.
