1[per thousand]) and were relatively closer to either net plankton (-21.
Two vertical tows were made to collect samples of net plankton (composed mainly of micro and meso- zooplankton and minority of small, chain-forming phytoplankton) using NORPAC (standard North Pacific) nets of 100 and 330 [micro]m mesh sizes.
Net plankton (100 and 330 [micro]m fractions) was sampled using twin-towed plankton NORPAC nets.
Net plankton samples of 100 and 330 [micro]m fractions collected during May, July 2005, and July 2006 in coastal areas adjacent to Tokoro sowing farming sites exhibited an average of -25.
Results showed that there is a possibility that the hanging cultured scallops are feeding on net plankton as reflected by nearest isotopic values to ctenidia and muscle.
In contrast, net plankton was enriched in [delta][sup.
However, in terms of net plankton isotopic values, high [delta][sup.
