分析了北太平洋鱿鱼渔场浮游植物种类组成、分布特点及其与环境、中心渔场的关系.初步鉴定出36属129种,种类组成以暖水性种类居多(占58 9% ),虽然冷水性占种类比例较少(占10 9% ),但在细胞数量上占明显优势(占总量的68 05% ),出现热带、亚热带与亚寒带区系共存的局面;其平面分布不均,平均总量为54 60×103个/m3;冷暖水系对浮游植物种类组成及数量分布均有显著的影响;中心渔场的形成与浮游植物高值区有着密切的关系.
The species composition and distribution characteristics of phytoplankton in the Pacific North Pacific squid fishery and its relationship with the environment and the central fishery were analyzed.Among the 36 genera and 129 species, 129 species were identified, of which the species were mostly warm water (58.9%), although cold water accounted for (10 9%), but the number of cells accounted for obvious advantages (68 05% of the total), showing the coexistence of tropical, subtropical and sub-arctic zones; the uneven distribution, the average total 54 × 103 plants / m3. The cold and warm water systems had a significant effect on the species composition and quantity distribution of phytoplankton. The formation of the central fishery was closely related to the phytoplankton high value area.
