Artemia is based on the nutrient requirements of larval fish and crustacea that was researched by growers and specialists . in order to provide the necessary nutritional requirements our ingredients include fresh fish , hog liver and whole egg liquified by enzymes under 50 , which can provide nucleic acid and unknown growth factors , supplementing the insufficient nutrition in natural artemia 維仁公司生產的維仁牌人工鹵蟲，魚苗丹是用生鮮魚蝦豬肝以酵素于下分解，取濾液與生蛋維他命微量礦物質于以下聚合而成，其原料保有天然的核酸酵素及許多未知天然生長激素，其營養理論上應比天然鹵蟲 |

This research reviewed the relationships of the myriapods to other arthropoda , based on morphological and molecular sequence data and the studies of developmental biology . the review was followed the major controversies in the higher - level phylogeny of myriapods . the complete 18s rrna sequences of four groups of myriapoda plus hexapoda ( protura , diplura , insecta ) and crustacea were used for phylogenetic study 本研究首先從形態學性狀、分子性狀( dna和蛋白質)以及結合形態和分子性狀、發育生物學的研究等方面對多足類動物與其他節肢動物之間的親緣關系進行了綜述，同時對多足類的系統發生研究進行了綜述。 |
