摘要
幼鲍初期饵料生物在玻片上附着生物量的消长与光强度的关系进行了试验。光强度超过2500Lux时微生物膜增长较快,膜脱落较早多光强度低于1000Lux时微生物膜净生产量较依;光强度在1500-2000Lux时有利于膜生物量的积累。舟形藻和菱形藻的纯培养在玻片上附着的生物量呈稳定性高速增长并能延迟生物膜脱落现象的发生.
The pressent study deals with the effect of light on the sessile microbiol filmon slide glass for feeding yoting abalone. The following results were obtainedThe light intensity for the optimal growth of microbiol film on the glass wasabout 1500-2000 1ux. It was possible that it came off frenquently from the filmover 2500 1ux, and that biomass of the film was lower below 1000 1ux.It was probable that pure culture of attached diatoms, nam1y Ntzschfa sp. andNavicula SP,, on the glass might lead to larger amounts of biomass of microbiol film.This result proposed that pure culture of attached diatoms might be a promisingmethod for feeding young abalone.
