Resumo: | Technology for the culture of the pink shrimp Farfantepenaeus paulensis in low-cost cages and pen enclosures was developed together with artisanal fishermen of the Patos Lagoon estuary, southern Brazil. Although the production of postlarvae (PL) under laboratory conditions is well documented, survival and growth during the nursery phase cages and pen enclosures in the nature has not yet been analyzed. Therefore, the present study compared survival and growth of F. paulensis postlarvae reared either in cages or pens. Six cages (2.0 2.0 1.4 m) of PVC-coated polyester with a mesh size of 1.5 mm were stocked with 800 PL26 each. To assess the effect of the substrate, a 10 cm layer of sand was added to three of these cages to simulate a pen enclosure. No difference in the mean survival rate between cages (92.2%) and pens (88.7%) was found (P > 0.05). However, final weight of shrimp reared in pens (1.05 ± 0.05 g) was higher than thosekept in cages (0.88 ± 0.12 g). The nursery phase of F. paulensis in cages and pens did not affect survival. Nevertheless, because of the higher growth rate of shrimp grown in pen enclosures, this kind of structure should be preferentially used in nursery rearing of this species. |

Embora a tecnologia para o cultivo intensivo de pós-larvas (PL) em laboratório já esteja bem documentada, informações referentes à sobrevivência e crescimento desses organismos na fase de berçário ainda são escassas para cercados e gaiolas no ambiente natural. Em virtude destes fatos, o objetivo do trabalho foi comparar o crescimento e a sobrevivência de pós-larvas de F. paulensis durante a fase de berçário em gaiolas e cercados no ambiente. Para o desenvolvimento do trabalho, foram utilizadas seis gaiolas(2,0 2,0 1,4 m) com malha de poliéster revestida de PVC com abertura de malha de 1,5 mm. Em cada unidade foram estocadas 800 PL26. Para verificar a influência do substrato, foram espalhados uniformemente 10 cm de sedimentos da própria enseada dentro de três gaiolas, simulando um cercado. A taxa de sobrevivência dos camarões obtida nas gaiolas foi de 92,2% e nos cercados de 88,7%, não sendo detectadas diferenças (P > 0,05). Porém, o peso médio final dos camarões nos cercados (1,05 ± 0,05 g), foi superior (P < 0,05) ao peso dos camarões nas gaiolas (0,88 ± 0,12 g). A espécie pode ser cultivada na fase de berçário em gaiolas ou cercados sem prejuízo à sobrevivência final. Entretanto, recomenda-se que a fase de berçário seja realizada preferencialmente em cercados.2012-07-05T20:05:14Z2012-07-05T20:05:14Z2004info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfVAZ, Luciano Jensen, et al.
