“…In part, this is explained by the presence of juvenile and non-adult specimens in the estuaries (Vega-Cendejas & Hernández de Santillana, 2000), but in part this is the result of the small size reached even by the adults in these ecosystems. This matter is discussed in more detail by Legendre & Albaret (1991) and Bouchereau et al (2000), and should be considered when aquaculture begins to be encouraged in the estuaries. Kapetsky & Lasserre (1984) discuss the relatively modest revenue achieved from fishing in lagoonal-coastal systems.…”

BrazilTechnical, biological and socioeconomic factors act as obstacles in the development of fishing activity in the Guaratuba Bay, southern Brazil. Amongst the difficulties registered, the following stand out: there was little variety of fishing gear; the purchasing power of the fishermen was low; there was a lack of regularity in the presence of the target species in the estuary; legislation restricted the use of certain gear at particular times; the size of the individual fish was small when compared to those from the continental shelf. Aquaculture could offer an alternative to the revenue of the fishermen, but cultural tradition and the lack of financial resources make it difficult to introduce aquaculture as an activity for the fishermen. The pessimism encountered in the community indicates that the future of artisanal fishing in this estuary is uncertain.

“…Use of anesthetics is increasingly common in modern aquaculture and has practical relevance in diverse husbandry manipulations in addition to potentially attenuate physiologic response to stress (CUNHA et al, 2010;BECKER et al, 2012;PARODI et al, 2014 The essential oil of Aloysia triphylla (L'Herit) Britton (EOA) presented anesthetic efficacy in the freshwater silver catfish Rhamdia quelen (PARODI et al, 2014), but no studies in other fish species have been performed. The fat snook, Centropomus parallelus, is an inshore tropical euryhaline species with high flesh quality and market value, as well as significant aquaculture potential (BOUCHEREAU et al, 2000). Therefore the aim of this study was to investigate the anesthetic induction and recovery times of the EOA, its efficacy as a stress-reducing agent during the transport of fat snook and the influence of salinity on the effect of EOA.…”
