| 中文摘要: |
| 为确定斑节对虾选育中家系幼虾标粗合适的放养密度袁在室内、外分别按200、300、400尾/m2的密度养殖斑节对虾仔虾（PL15）40d，每两天以日投饲量的75%添加糖蜜和两种商品微生态制剂（利生菌王和BZT®碧水），比较两种微生物制剂对斑节对虾生长和存活的影响及对水质的调控效果。结果表明，随着养殖密度上升袁，室内组和室外应用利生菌王组的斑节对虾特定生长率（SGR）和成活率（SR）呈下降趋势，室外应用BZT®碧水的斑节对虾SGR呈下降趋势，而SR呈先上升后下降趋势。各试验组水体中的氨氮（NH4-N）、亚硝酸氮（NO2-N）、硝酸氮（NO3-N）和磷酸盐（PO43--P）均随养殖时间和养殖密度的增加而升高，其中200尾/m2组各指标最低，400尾/m2组最高。相同密度下，室内应用利生菌王的试验组的NO2-N浓度均低于BZT®碧水组，室内外应用利生菌王试验组的NH4-N浓度均高于BZT®碧水组。 |
| 英文摘要: |
| In order to determine the appropriate stocking density for the juveniles in the Penaeus monodon selective breeding program, the study designed indoor and outdoor aquaculture system to rear P. monodon larvae (PL15) for 40 days at the densities of 200, 300, 400 individuals/m2, respectively, added molasses every two days at 75% of the day feeding amount and two kinds of commodities probiotics (LSJW and BZT®BS), to compare the effect of two probiotics on the growth and survival of P. monodon and the regulation of water quality. Results showed that, with the stocking density increasing, the specific growth rate (SGR) and survival rate (SR) decreased in indoor group and outdoor group that used LSJW, the SGR decreased in outdoor group that used BZT 砸, while the SR decreased after the first rise. With the increase of stocking density and breeding time, the contents of NH4-N, NO2-N, NO3-N and PO43--P all increased, in which the indexes were the lowest in 200 individuals/m2 group and were the highest in 400 individuals/m2 group. Under the same density, NO2-N concentration in LSJW group was lower than that in BZT®group in indoor aquaculture system, NH4-N concentration in LSJW group was higher than that in BZT®group in indoor and outdoor aquaculture system. Key words: probiotics; Penaeus monodon; specific growth rate; survival rate; water quality |
