In summer and autumn in the Southern Yellow Sea, the East China Sea in northern of small yellow croaker and zooplankton cheap Oakley Sunglasses Canada quantity distribution and cheap Oakley Canada Review their relationship were studied. The results show that: in summer and autumn, yellow Department of Hainan, in the northern part of the East China Sea of small yellow croaker occurred mainly in the Dasha River,, Lusi coast and sand fishing ground, summer is the highest biomass distribution area in at the junction of the Yangtze River Estuary and river fishing ground of 31 degrees 30 \'n, 125 degrees 00\' e sea, autumn is the highest biomass distribution area in Da Sha and Sha fishing ground at the junction of the 32 degrees 30 \'n, 125 degrees 00\' e sea. The dominant species of zooplankton in the 2 seasons were mainly Cheap Oakleys Canada composed of zooplankton, pelagic larvae and the main animal. Zooplankton two dense area: A in buy Oakley Canada the vicinity of the near shore side 123 degrees 00 \'e longitude line, that of the summer is the north-south direction distribution, autumn is the Northwest - southeast direction; the other a in the waters near the 32 degrees 00 n\', 125 degrees 00 e \'. From summer to autumn. The composition of dominant species of zooplankton have great change, and expand the scope of dominant species; summer cheap Oakley Canada accounted for absolute advantage of Calanus sinicus in autumn is not in the dominant species of the column. The high density area in summer and autumn of small yellow croaker in the main distribution area and the relationship between planktonic animal good. Little yellow croaker in summer and other planktonic feeding fish strong grazing impact may caused by the sharp decline in the autumn of zooplankton abundance. discount Oakley Canada Small yellow croaker is mainly distributed in the seasonal variations of the bait dominant zooplankton species may have an important effect on the food selection changes.
