【摘要】:根據(jù)2012年12月~2013年5月對(duì)江蘇沿岸陸上養(yǎng)殖池塘內(nèi)綠藻的調(diào)查,通過分析陸上養(yǎng)殖池塘綠藻成體和顯微繁殖體的分布、種類組成,結(jié)合養(yǎng)殖池塘的社會(huì)調(diào)查結(jié)果,討論陸上養(yǎng)殖池塘作為綠潮源頭的可能性。結(jié)果顯示:從區(qū)域分布上看,養(yǎng)殖池塘中出現(xiàn)綠藻和綠藻顯微繁殖體的區(qū)域主要分布在江蘇南部的南通地區(qū)。從時(shí)間上來看,蓄水河道中的綠藻出現(xiàn)在3月、4月以及5月;養(yǎng)殖池和蓄水河道的綠藻顯微繁殖體出現(xiàn)在2~5月。在池塘養(yǎng)殖工藝中,進(jìn)水后養(yǎng)殖戶會(huì)對(duì)池水進(jìn)行消毒,這一措施將抑制甚至殺滅綠藻顯微繁殖體,顯微繁殖體不會(huì)長成綠藻。養(yǎng)殖活動(dòng)結(jié)束后,排水時(shí)養(yǎng)殖戶在取排水的閘口處放置篩網(wǎng),綠藻會(huì)被過濾在篩網(wǎng)上,很少被直排入海。本研究結(jié)果表明,陸上養(yǎng)殖池塘不可能是綠潮災(zāi)害的源頭。
[Abstract]:Based on the investigation of green algae in onshore culture ponds along Jiangsu coast from December 2012 to May 2013, the distribution and species composition of green algae adults and micropropagates in onshore culture ponds were analyzed, and the results of social investigation in culture ponds were combined. The possibility of onshore culture pond as a source of green tide is discussed. The results showed that the distribution of green algae and micropropagation was mainly in the Nantong area of southern Jiangsu Province from the point of view of regional distribution. In time, the green algae appeared in March, April and May, and the micropropagation of green algae in aquiculture pond and water storage channel appeared from February to May. In the pond culture process, the breeders will sterilize the pond water after the influent. This measure will inhibit or even kill the micropropagation of green algae, which will not grow into green algae. After the culturing activities were finished, the farmers placed sieve nets at the gate of drainage, and the green algae were filtered on the sieve nets and rarely discharged directly into the sea. The results show that the onshore culture pond can not be the source of the green tide disaster.
