O antagonismo do modelo de crescimento econômico infinito dentro de um planeta finito, com problemas sociais e ambientais, impõe a necessidade de discussão desse modelo e seus limites, diante do desafio da sustentabilidade. Por essa razão, o presente artigo tem como objetivo abordar tendências agroecológicas na produção agropecuária sob um enfoque de processos sustentáveis. Tratou-se da adubação e da necessidade de recomendações para adubação em sistemas orgânicos e de transição, e dos sistemas agroflorestais e consórcios perenes, como tendências do processo de transição agroecológica. Também foram tratados os temas certificação, organização social, comercialização, assistência técnica e extensão rural, entendendo-os como fundamentais para a promoção dos sistemas agroecológicos.

For this reason, the present article aims to discuss agroecological trends in agricultural production under a sustainable processes approach. In particular, the focus was on fertilization and the need for recommendations for transitional and organic systems, as well as on agroforestry systems and perennial consortium as trends in agroecological transition. Topics such as certification, social organization, marketing, technical assistance and rural extension were also considered as fundamental for the promotion of agroecological systems.

High-quality live food is essential for reducing the frequent high mortality of newly hatched fat snook (Centropomus parallelus) larvae in hatcheries. Copepods, a rich nutrition source, cultivated with the microalgae Chaetoceros muelleri and Isochrysis galbana, were evaluated as food for 0?14-day-old larvae. Two experiments were performed using nine 50-L tanks stocked with 2500 embryonated fat snook eggs. Three different dietary (treatments) were tested in triplicate: Experiment 1, Treatment 1 (Control), using rotifers Brachionus rotundiformis (20 mL− 1); Treatment 2 (Copepod), larvae were fed with Acartia tonsa (nauplii and copepodits, 0.1 mL− 1); and Treatment 3 (Mixed), larvae were fed with A. tonsa (0.05 mL− 1) and rotifers (10 mL− 1). In Experiment 2 to increase the density of live food, food organisms and the phytoplankton were introduced into the experimental tanks with the embryonated eggs and were stocked: Treatment 1, 20 rotifers mL− 1; Treatment 2, 0.5 copepods mL− 1; and Treatment 3, 10 rotifers mL− 1 and 0.25 copepods mL− 1. In Experiment 1, the Mixed Treatment increased significantly the survival rate (16.0% ± 7.5%) and mean larval weight (0.84 ± 0.05 mg) in relation to the other treatments. In Experiment 2, we observed significant improvements in larval notochord flexion in the Copepod and Mixed Treatment. The essential fatty acid profile of fat snook eggs had a DHA:EPA:ARA ratio of 11.4:2.4:1.0 while larvae in the Mixed and Copepods Treatments had ratios of 2.5:1.9:1.0 and 5.5:1.9:1.0, respectively. We conclude that the survival, development and the relationship between the major fatty acids were improved in treatments with copepods.
