In all zooplanktons, the site-occurrence-rates of Copepoda and Chaetognatha were the highest, 100% and 93.3%, and the average biomass of which were 298.56 mg·m-3 and 118.09 mg·m-3 and the summation accounted for 96.88% of total biomass. The result shows that these two species created a strong relationship with the distribution of saury fishing grounds, and their biomass can be considered as the important indicator of looking for the main saury fishing grounds.

An investment banking firm acting as underwriter sells securities from the issuing corporation to the public. A group of firms may from a syndicate to pool the risk and assure successful distribution of the issue. There are two types of underwriting arrangements: best efforts and firm commitment. With best efforts, the underwriters have the option to buy and authority to sell securities, or if unsuccessful, may cancel the issue and forgo any fees. This arrangement is more common with speculative securities and with new companies.
