摘要
于1999年进行两批次紫海胆(Anthocidariscrassispina)育苗试验,浮游幼体以螺旋藻粉+光合细菌和球等鞭金藻+螺旋藻粉的两组饵料进行培育,当幼体发育变态为后期八腕幼体并30%幼体管足从前庭腹合体伸出之后,以已培养底栖硅藻的塑料薄膜进行采苗。附着后的稚海胆经过3个多月培育,壳径达到3～5mm剥离到网箱中进行中间培育。本试验两批共培育出壳径为2～11mm的海胆苗105155个,探索出易于推广应用的紫海胆育苗工艺。
The techniques of artificial breeding of the larvae studied in 1999. The planktonic larvae of A, crassispina were fed platenesis powder ＋ photosynthetic bacteria or Spirulina platenesis developed to later eight-arm larvae and more than 30% of the transparent PE film with well-developed benthonic algae was used shell diameters of the juvenile urchins reached 3-5ram and they were and juveniles of Anthocidaris crassispina were with either of the following foods： Spirulina powder ＋ Isochrysis galbana. After the larvae larvae extended their vestibular complex, the to collect them. 3 months after settlement, the transferred into cages for middle culture. In this study, 105 155 young urchins with 2-11mm in shell diametcr were obtained and the applicable and suitable techniques for artificial breeding of A, crassispina to be popularized were gained.
