14. Estudo do crescimento, eficiência de biofiltração e cinética de absorção de nutrientes (N-NH, N-NO e P-PO4) da macroalga Gracilaria cervicornis (Turner) J. Agardh
The objective of this study was to examine the growth of Gracilaria cervicornis cultured in a shrimp (Litopenaeus vannamei) pond and to determine the absorption efficiency and the kinetics parameters (Vmax, Ks e Vmax:Ks) of this macroalgae for the nutrients N-NO3-, N-NH4+ and P-PO4-3, aiming at its use as bioremediatory of eutrophicated environments. For thi

15. Avaliação das comunidades planctônicas e bentônicas de microalgas em viveiros de camarão (Litopenaeus vannamei)
The present study aimed to evaluate the dynamics of planktonic and benthic communities of microalgae, and establish relationships with the hydrological variables, management practices and the production data of the shrimp ponds. During one year, three Litopenaeus vannamei ponds and the affluent channel were analyzed by taking phytoplankton and benthos sample

17. Efeitos do substrato e da densidade populacional sobre as atividades comportamentais e níveis de homócitos em relação à densidade em Litopenaeus vannamei (BOONE, 1931)
Carciniculture in Brazil occupies world-wide prominence due to shrimp culture, and the state of Rio Grande do Norte has presented the best results in the culture of the Litopenaeus vannamei in the last decade. This species has been shown to adapt easily to different environments and is between the five most cultivated penaeids of the world. The ponds are usu

18. Biodiversidade e abundância da ictiofauna associada ao cultivo orgânico de Litopenaeus vannamei (Boone, 1931)
The expansion of shrimp farming has caused a series of environmental impacts, often as a result of lack of planning and adequate management. Organic aquaculture has emerged as an alternative to conventional shrimp farming, and differently, aims at the economical, ecological and farming potential of other organisms, such as fishes, oysters and seaweeds. The p

20. Avaliação da toxicidade de florações naturais e de cultura de cianobactérias: efeitos sobre Ceriodaphnia silvestri (Crustacea, Cladocera)
The incidence of toxic cyanobacterial blooms is one of the important consequences of eutrophication in aquatic ecosystems. It is a very common phenomenon in reservoirs and shrimp ponds in the State of Rio Grande do Norte (RN), Brazil. Cyanobacterias produce toxins which can affect aquatic organisms and men trough the food chain. Aiming to contribute to the s

21. CondiÃÃes higiÃnico-sanitÃrias da Ãgua e do camarÃo em duas fazendas de cultivo de pequeno e mÃdio portes, no estado do Cearà / Hygienic-sanitary water and shrimp farms in two-growing small and medium businesses in the state of CearÃ
The shrimp species Litopanaeus vannamei is the single most important aquiculture resource in Northeastern Brazil. However, the rapid expansion of the activity has brought with it a number of water and food-borne bacterial diseases. The objective of the present study was to evaluate and compare the sanitary conditions of shrimp and pond water sampled at one s

22. Characterization of shrimp ponds and effluents sedimentation pond in Rio Grande do Norte: subsidies to the protection of the ecosystems in this study / Caracterização dos meios de cultivo de viveiros de carcinicultura e da lagoa de disposição dos efluentes no Rio Grande do Norte: subsídios para proteção dos ecossistemas deste estudo
O cultivo de camarões é uma importante atividade econômica em zonas costeiras de muitos países. No Brasil, a carcinicultura teve início no Rio Grande do Norte em 1973 e, atualmente, consolida-se como principal produto da pauta de exportação desse estado, sucesso devido principalmente ao seu clima semi-árido, à vasta costa litorânea com extensas ár

23. Cultivo do camarão marinho Litopenaeus vannamei (Boone,1931) em sistema multifásico / Cultivo do camarão marinho Litopenaeus vannamei (Boone,1931) em sistema multifásico
Marine shrimp in Brazil has grown very fast in the last years due to adoption of new technologies applied to the activity. One of these refers to the use of nursery tanks to post larvae acclimation from the hatcheries. These nursery tanks have the advantage to reduce the culture time, increasing the ponds rotativity and consequently increasing the production
