稻叶、今井等曾经做过有关刺参(Sti-chopus japonicus)苗种生产的研究工作,其中稻叶研究的是刺参的人工授精,而今井等则使用切除法取得成熟卵,并以滴虫属作为浮游期饵料,成功地培育成稚参。近几年石田采用温度刺激法,获得大量成熟卵。以单鞭金藻或者角毛藻为浮游期饵料效果更佳,故可大量生产稚参苗种。但从附着后提高放流效果来看,把稚参培育到体长30毫米、或体重1克的规格,对其适宜的饵料和饲育方法至今尚未肯定。因此,本试验以附着后稚参的适宜饵料和饲育方法为目的,自1983年
Inaba and Imai have done research on the production of Sti-chopus japonicus seedlings. Among them, the research on inaba of rice is artificial insemination of sea cucumbers, and Imai et al. Use the excision method to obtain mature eggs, Insect as a plankton bait, successfully cultivated into juveniles. In recent years Ishida using temperature stimulation, access to a large number of mature eggs. Monochoria or Chaetoceros plankton bait for better results, it can be mass-produced juvenile seedlings. However, from the perspective of improving the discharge effect after attachment, it is still not yet certain about the suitable feeding and breeding methods for juvenile ginseng to grow to 30 mm in body length or 1 g in body weight. Therefore, the purpose of this experiment with the appropriate bait and breeding method for juveniles after attachment, since 1983
