Added bagasse and Bacillus sp. to Litopenaeus vannamei intensive culture tank, the treatment groups were treatment A（added Bacillus sp.）, treatment B（added Bacillus sp. with crushing bagasse） and treatment C（added Bacillus sp. with crushing-steaming bagasse） respectively. To estimate the effect of addition of bagasse with Bacillus sp. on the culture environment and shrimp growth, the level of total ammonia nitrogen（TAN）, nitrite nitrogen and nitrate nitrogen, total amount of bacteria in the water and shrimp growth were determined. The result suggested that the TAN concentration in treatment B and C were significantly lower than that in treatment A during the early stage of the culture（P〈0.05）. The addition of bagasse with Bacillus sp. was contribute to the formation of bio-floccules. The concentration of bio-floccules in treatment B and Cwere 6.3-20 ml/L and 8.3-30 ml/L respectively, which were significantly higher than that in treatment A（2.7-8.3 ml/L） during the culture（P〈0.05）.The average weight of shrimp in treatment B and C were 8.56±0.21g and 8.84±0.26g respectively, which were significantly bigger than that in treatment A（7.66±0.40g） when harvest（P〈0.05）. 相似文献

Simulated water system was applied to investigate the filtration rate, feed intake rate and absorptivity of the scallop whose feed was Phaeodactylum tricornutum, compound feed and faeces, respectively. The absorptivity of the mentioned feeds was 73.78±2.30（%）,63.42±1.23（%）and 67.79±0.64（%）, respectively, and the results indicated that the scallop can utilize the organic waste effectively and reasonable polycuture of fish and shellfish can ease the environment pollution. 相似文献
