## Abstract The effects of the pesticide hexachlorocyclohexane (HCH) on the nitrogen fixing blue‐green algae __Anabaenopsis raciborskii__ and __Anabaena aphanizomenoides__ commonly found as blooms in fish ponds were studied. These algae were very sensitive to HCH, and a distinct decrease in growth

✦ Synopsis
Abstract
Growth and fixation of nitrogen were retarded in Anabaena doliolum when grown on elemental nitrogen in presence of four different herbicides. The alga was found to be intolerant to these chemicals under nitrogen fixing conditions even in low concentrations. An inhibition of photosynthesis has been regarded as the main basis of herbicidal activity besides other interactions.
