No. of bitstreams: 1 LigiaGR.pdf: 427991 bytes, checksum: fd90b864e24611c634c5ec114b00d8f7 (MD5) Previous issue date: 2008-08-29 / The main problem faced by the shrimp industry are the infectious diseases. The hypodermal and hematopoietic necrosis infection (IHHN) is one of the major cause of disease in the cultured shrimp, Litopenaeus vannamei. Environmental changes involving water quality, oxygen concentration, salinity, temperature, stocking density, presence of pathogens, among others, triggering a stressing condition for the cultured shrimp, weakening them and allowing the outbreak of diseases. The stress on the animal leads to a change in the molecules immune response components, which can be used as indicators of shrimp health. Thus, the objective of the present study was to evaluate the effect of salinity, stocking density and IHHNV infection on the L. vannamei shrimp. The immune parameters used to check the shrimp health were the total hemocytes counts (THC), the agglutinating activity (AA) and the clotting time (CT) of the serum of shrimp. These parameters were analyzed in healthy and IHHNV-infected shrimp, grown in low (0-0.5 ), medium (19-24 ) and high (> 38 ) salinity, and extensive (7-12 cam.m-2), semi-intensive (15-25 cam.m-2) and intensive (33-45 cam.m -2) stocking density. The IHHNV infection rate was significantly higher in low salinity (P<0.005) and intensive density (P<0.005), both stressful conditions for L. vannamei. Low salinity significantly increased THC (P<0.05) and decreased and CT (P<0.05) in healthy and infected shrimp, but AA (P<0.05) significantly decreased in healthy shrimp at medium salinity. Culture intensification did not affect the THC, AA and CT of healthy and infected shrimp (P>0.05). The IHHNV infection did not affect any immune parameters of shrimp cultured at different salinities and stocking densities. It is necessary to emphasize that this study was conducted in shrimp grown in ponds, where several environmental factors are acting simultaneously. Thus, further studies are needed about the influence of other environmental factors on the immune parameters of shrimp cultured in pond / O principal problema enfrentado pela ind?stria do camar?o s?o as enfermidades de origem infecciosa. A Infec??o Hipodermal e Necrose Hematopoi?tica (IHHN) ? uma das principais causas de doen?as no camar?o de cultivo Litopenaeus vannamei. Altera??es do ambiente de cultivo envolvendo qualidade da ?gua, concentra??o de oxig?nio, salinidade, temperatura, densidade de estocagem, presen?a de pat?genos, entre outros, desencadeiam uma situa??o de estresse nos camar?es cultivados, debilitando-os e permitindo a instala??o de enfermidades. O estresse desencadeia no animal a altera??o de mol?culas componentes da resposta imune, que podem ser usadas como indicadores de sa?de do camar?o. Desta forma, o objetivo do presente trabalho foi avaliar o efeito da salinidade, densidade de estocagem e infec??o pelo IHHNV na imunidade do camar?o de cultivo L. vannamei. Os par?metros imunes utilizados para monitorar as condi??es de sa?de dos camar?es foram o n?mero total de hem?citos (THC), a atividade aglutinante (AA) e o tempo de coagula??o (TC) dos soros dos camar?es. Estes par?metros foram analisados em camar?es saud?veis e infectados pelo IHHNV, cultivados em baixa (0-0,5 ), m?dia (19-24 ) e alta (>38 ) salinidades e em extensiva (7-12 cam.m-2 ), semi-intensiva (15-25 cam.m-2) e intensiva (33-45 cam.m-2) densidades de estocagem. A taxa de infec??o pelo IHHNV foi significativamente maior em baixa salinidade (P<0,005) e na densidade intensiva (P<0,005), ambas condi??es estressantes para o L. vannamei. Baixa salinidade significativamente aumentou THC (P<0,05) e diminuiu TC (P<0,05) de camar?es saud?veis e infectados, mas AA (P<0,05) de camar?es saud?veis diminui significativamente na m?dia salinidade. A intensifica??o do cultivo n?o afetou THC, AA e TC de camar?es saud?veis e infectados (P>0,05). A infec??o pelo IHHNV n?o afetou nenhum dos par?metros imunes dos camar?es cultivados nas diferentes salinidades e densidades de estocagem. ? necess?rio enfatizar que o presente estudo foi realizado em camar?es cultivados em viveiros, onde v?rios fatores ambientais est?o atuando simultaneamente. Desta forma, s?o necess?rios estudos adicionais sobre a influ?ncia de outros fatores ambientais nos par?metros imunes de camar?es nas condi??es de cultivo
