After molting three times, the zoea enter the mysis stage during which they begin to look more like adult shrimp and swim in a characteristic fashion with head and tail pointed downwards at right angles and occasionally performing a sudden retrograde jumping action. this is known as the inversion state, the fry being suspended upside - down in the upper middle region of the pond water. this is, therefore, also called the " inverted suspension phase "
眼幼蟲脫第三次即進入糠蝦期幼蟲期mysis stage ,此期之體形已略成蝦之狀態,且具特有之游泳姿態,即頭部及尾部均向下,成一直角彎曲而時作向後跳躍游動,又因成倒立狀態,懸浮於水中的中上層,又叫倒吊期,此期幼蟲對外界的環境因素,如水溫鹽分等變化,比前兩期來得更具適應力,主要餌料為豐年蝦brine shrimp的幼蟲,但其他大小略同的動物性浮游生物,如橈腳類copepoda輪蟲類rotifera均可。Other plankton species in near equal numbers replaced calcareous microplankton as they died out.
鈣質微體浮游生物消亡時,已經有近乎等量的其它浮游生物種類代替它們了。Plankton volume indicator
浮游生物體積測量器In the periods of peak zooplankton abundance , that is , in the late spring and in the summer , haney recorded maximum daily community grazing rates , for nutrient - poor lakes and bog lakes , respectively , of 6. 6 percent and 114 percent of daily phytoplankton production
在浮游生物數量高峰期,也就是晚春和夏季的時候,漢尼分別在營養匱乏的湖泊和沼澤做了紀錄,發現浮游生物每日的群體覓食量是每日浮游植物產量的6 . 6 %和114 % 。But the gut evacuation rates did not vary with the experimental temperature and body size. copepods usually performed feeding rhythms with maximum level at midnight and their feeding activities changed with the tide rhythms at the estuary area. in the laizhou bay, the daily grazing rate of the copepod population on phytoplankton was 20. 81 ? 98. 35 % of the primary production and 2. 53 ? 6. 36 % of the phytoplankton standing stock in summer
現場測得的橈足類攝食率結果表明,在萊州灣,夏季橈足類群體的日攝食量占初級生產力的20 . 81 ? 98 . 35 % ,占浮游植物現存量的2 . 53 ? 6 . 36 % ,濰河口,河口外浮遊動物優勢種群體的日攝食量占初級生產力的32 . 28 % ,占浮游植物現存量的14 . 12 % ,河口內對初級生產力的攝食壓力< 3 % ,日攝食量小於浮游植物現存量的1 % 。Much to our surprise when the plankton entered the oyster tried very hard to expel the plankton. within3 - 5 minutes, the movement of the heart became very abnormal and the oyster died at once

水體和沉積物中生物硅含量與浮游植物總量、硅藻生物量、有機碳表現為正相關。Only the water at jiekou had been eutrophic. the result of biological assessment was that the average density of phytoplankton at all the sampling spots was more than 1, 000, 000 per litre, indicating that the lake was eutrophic going by the population density. but this density of phytoplankton was higher than that in similar lakes at the same pollution level
生物評價結果認為,千島湖浮遊藻類平均密度較同類營養水平的淡水水體高,其所有取樣點浮遊藻類平均密度都10 ~ 6個? l ,國內外一般認為當浮游植物平均密度10 ~ 6個? l時,其已經達到富營養化水平,因此單從浮游植物密度來看,可以認為千島湖已達到水體富營養化。Red tide occurs randomly, with short duration and large incidence. airborne hyperspectral remote sensing technique can play an important role in red tide ' s monitoring. and the precondition is to acquire in situ spectral data of red tide, to grasp red tide ' s spectral characteristics by data processing and analysis and to set up spectral library of different dominant species of red tide
赤潮是海水中的浮游生物在一定條件下過度繁殖或聚集致使海水變色的一種生態異常現象,因其具有隨機性、突發性、持續時間短、影響范圍大等特點,客觀上要求利用航空高光譜遙感技術對其進行監測;但首要的前提與基礎性工作是大量獲取赤潮水體的現場光譜數據,通過處理與分析,掌握其光譜特性,不斷充實赤潮優勢種類的光譜數據庫。In the past 40 years, the great change of nutrient structure has lead an obvious effects on the jiaozhou bay ecosystem, the silicate cycling has received significant scientific attention. an improved method is applied to the study of bsi in jiaozhou bay, the relationship between bsi and the phytoplankton, nutrient and organic carbon were discussed, the bsi cycle was studied simply
