    <p>It has been thought that food availability for fish larvae was poor in the Kuroshio because of the low standing stocks of plankton in the oligotrophic conditions under thermal stratification throughout the year. Despite a potential risk or disadvantage for larval survival and growth, Kuroshio and its neighbouring waters are nursery grounds for the early life stages of various fishes. Here, we compared the growth activity of fish larvae among 15 taxonomic groups, including 11 families in the Kuroshio and its neighbouring waters, based on protein synthetase activity and protein contents. Protein-specific (<sub>sp</sub>AARS), individual-based aminoacyl tRNA synthetase activities (<sub>i</sub>AARS), and protein contents (PRO) of fish larvae ranged from 2 to 232 nmol PPi mg protein<sup>−1</sup> h<sup>−1</sup>, from 1 to 21 μmol PPi ind<sup>−1</sup> d<sup>−1</sup>, and from <1 to 26 mg ind<sup>−1</sup>, respectively. <sub>sp</sub>AARS, <sub>i</sub>AARS and PRO were variable among the taxonomic groups and were not classified between mesopelagic groups and the others. Compiling these measurements among all taxonomic groups, a significant negative correlation was found for <sub>sp</sub>AARS to PRO. The correlation showed no significant difference between the Kuroshio and its neighbouring coastal waters, indicating that growth activities to fish larvae body mass were comparable in the Kuroshio and its neighbouring waters. Based on nonmetric multidimensional scaling on <sub>sp</sub>AARS, <sub>i</sub>AARS and PRO among 15 taxonomic groups, two different groups were classified for fish larvae, represented by the high <sub>i</sub>AARS under the high PRO but low <sub>sp</sub>AARS (Group 1) and the low <sub>i</sub>AARS under the low PRO but high <sub>sp</sub>AARS (Group 2), representing the different life strategies for larval growth among the taxonomic groups. The present findings suggest that these biochemical indices are useful for evaluating the growth activity of fish larvae among various taxonomic groups and that food availability is not poor enough to support larval growth in the Kuroshio and its neighbouring waters.</p>

    Plankton community structure, standing stocks and productivity were compared between upstream and downstream of theTokara Strait based on Lagrangian oceanographic observations and sampling along the Kuroshio. Surface waters above 200mwere represented by lower temperature and salinity, and nutrients and chlorophyll a concentrations at the subsurface were higherdownstream than upstream. No significant difference was found in the zooplankton community structure, and the predominantcomponents were naked ciliates for microzooplankton and copepods for net zooplankton. Although the protein synthetase activityof the net zooplankton community was high throughout the stations, large metazoans were one cause of the increased biomass andproduction rates downstream. These results suggest that the nutrient supply and phytoplankton increased at the subsurface, andthe net zooplankton biomass and productivity increased downstream of the Tokara Strait.

    Training ships of Fisheries College were established to train ship's officers. These were based onthe law on University establishment standards. Recent marine science diversifies, and the purpose of atraining ship can't be called only the purpose which trains a sailor. For example, recent fishery isrequired not only to capture but also scientifically analyze and manage resources efficiently. Furthermore,the facilities which can deal with a marine environmental problem are necessary. The new practice shipneeds the latest research equipment and a structure that can use them effectively.  Kagoshima University training ship Kagoshima-Maru is based on the 'Basic Act on Ocean Policy'which came into effect in 2007 and was built by aggregating the requirements of the latest equipmentand hull structure. In this paper, the concept of Kagoshima-Maru construction and the problems whichbecame obvious later are described.
