【摘要】 <正> 饵料生物的人工培养是水产养殖工作的一个关键,在经济贝类的人工育苗过程中,依据贝苗幼体的摄食习性,选择和培养适宜的饵料生物,具有很重要的实际意义。 鲍是一种珍贵的海产贝类,其幼体在变态发育中从面盘期进入匍匐期之后,即以吻部舐食附着基面上的单胞藻,其他微小生物和有机碎屑。国外如Croft(1937)、梅林(1961)、酒井(1962)、菊地(1965)、今井(1967)等的报告,都曾指出过采用硅藻来培育鲍苗。几年更多还原

【Abstract】 This report presents the method of culturing benthic diatoms,used for feeding abalone larvae.During the season of abalone larva culture,the commone benthic diatom species were collected in the coastal area of Dongshan County,Fujian Province.After the settlement of benthic diatoms on the glass plate and the polyvinlyl plastic film,the algae were cultured on a large serge scale.The culture condition such as temperature,light,nutrients,quality of water,and predator were examined.Diatoms could be harvested after a weak of eulturing,i.e.the diatoms were washed down from the glass plates or transferred the whole glass plates into the culture pond of abalone larvae.The diatoms were used for feeding the abalone larvae and also for examining the effect of feeding.Comparison was made of the feeding of benthic diatoms with that of Plalymonas sp.,showing that in the former the quantity of food taken was greater (1.5 time) and the growth rate higher (1.6 time).更多还原
