Abstract
Effects on mosquito breeding, acidity, and fish presence were assessed afte r installation of a small tidal leakage port into an acidic drain's tidal e xclusion flap gate. Before gate modification the drain water had pH values as low as 2.7. These water conditions were toxic to fish and continually he ld mosquito larvae. At 4 wk after gate modification, water pH had risen to 6.0, at least 3 fish species inhabited the drain, and mosquito larval numbe rs had been reduced by 99.98%.
