Larval development of indigenous South American freshwater fish species, with particular reference to pacu (Piaractus mesopotamicus): A review

In recent years, a number of South American freshwater fish have gained increasing attention for their potential in aquaculture, not only because of their excellent performance in farming systems but also to meet the high consumer demand for these species due to declining fishery resources. Many South American freshwater species are migratory and produce altricial larvae, with a small amount of yolk reserves. Unlike precocial freshwater species and altricial coldwater marine fish, these freshwater fish investigated have rapid yolk depletion and metamorphosis. Specific studies on the initial development of South American fish are scarce and fragmented. One of the most widely studied species is the pacu (Piaractus mesopotamicus), farmed in warm continental waters. In the present review we compile new and published data on the initial development of pacu, including morphogenesis of the skeletal, muscle, digestive and sensory systems; compare it to other Neotropical species; and discuss the importance of this information to develop larviculture protocols. When pacu larvae exhaust yolk reserves, they initiate a new form of interaction with the environment, becoming exclusively exotrophic. This type of interaction is made possible by the rapid development of sensory, skeletal, locomotor and digestive structures. In addition to understanding fish ontogeny, studies on larval development are necessary to improve farming systems and larviculture techniques aimed at producing high-quality juveniles in aquaculture.

Aquisição da informação visual: controle da postura e do olhar

Postural control is needed to perform various daily activities, from staying in one posture, standing, to sports situations. Many studies have shown that sensory systems help to maintain posture stable; acquisition of perceptual information, particularly through head and eye movements, allows static and dynamic equilibrium. Research related to both motor behavior and physical activities such as gymnastics have contributed to a better understanding of complexities involved in human postural control. The purpose of this study was to review the related literature, searching for possible answers on how everyday and sports actions are performed, with respect to the control and maintenance of posture. Its focus was on how the human body acquires information from the sensory systems, vision in special, and how this information acts to support the control of posture and gaze

Proposal of architecture for launcher systems of unguided sounding rockets

This work presents a proposal of systemic architecture, to make automatic actions in the positioning of launch rail of unguided sounding rockets, which are based on a supervision system, a programmable logical controller, a sensory and actuators, available in Brazilian national market.
