如何殺池塘里的青苔藍藻

針對水產魚塘的“魚塘有水藻青苔怎么處理”問題,我委水產站的專家提出了池塘中常見的幾種水藻及處理方法,希望對你有幫助。 
1、水綿、雙星藻、轉板藻(俗稱青泥苔)。多在天氣轉暖后,在漁池淺水處萌發,長成縷縷細絲扎在池底,直立水中。衰老時斷離池底,漂浮水中,形成團團亂絲,魚苗魚種誤入其中易被纏繞而死。大量藻絲漂浮水中,還會影響浮游生物生長,使池水變瘦,不利于魚類生長。 
2、多甲藻、裸甲藻(俗稱紅水)。多發生在有機質多、硬度大、呈微堿性的池塘中,它們對環境變化極為敏感,如當水溫和pH值突然改變時,就會大量死亡,產生甲藻毒素,使魚中毒死亡,溫度變化較大的季節應特別注意。 
3、銅綠微囊藻,水花微囊藻(俗稱銅銹水)。這兩種微囊藻是常見的藻類,大量繁殖時則會造成危害。當大量藻體沉淀死亡時,微囊藻一方面會分解產生羥胺、硫化氫等有毒物質,另一方面還能分解耗氧而導致池水中嚴重缺氧。 
4、水網藻。多發生于水質較肥的淺水魚塘中,旺盛的絲狀藻體集結于網帶,魚苗誤入網中常會因呼吸困難和無法攝食而死亡。 
處理方法: 
1、人工撈除法。對于池塘表面大量蓄積的藻類,可以使用人工方法撈除。 
2、增氧法。安裝使用增氧機,對藻類有一定的抑制平衡作用。 
3、生物法。適當搭配鰱、鳙等濾食性魚類,合理投餌施肥,使用細菌類水質改良劑 
4、藥物法。 
(1) 放魚前使用生石灰徹底清塘。 
(2) 水綿發生后,可每畝每米水深使用除草劑撲草凈150-200克;也可用草木灰、生石灰撒向青苔泥上,或雨天后每畝每米水深用生石灰10-15公斤制成溶液潑灑。 
(3) 紅水發生后,每畝每米水深用生石灰15公斤制成溶液全池潑灑,以提高池水的pH值,使這些藻類死亡,然后換進新水。 
(4) 使用每立方米水體0.5-0.7克硫酸銅遍灑殺滅藻類,2天后再換進1/3的新水。 
(5) 須注意的是,藥物殺死藻類后,大量死亡的藻類腐爛易造成池塘水質變壞,導致水體嚴重缺氧,需要使用增氧機增氧或加注大量新水。密切注意魚群和水質變化,以便及時注入新水或采取增氧等措施。藥物本身毒性很大,這種方法應謹慎使用。
