Effects of pH and water turbulence on the growth of harmful algae pyrodintum bahamense var. compressum

Pyrodinium, a red tide causing dinoflagellates are often related to toxicity cases particularly paralytic shellfish poisoning (PSP). Study on the effects of specific parameter on the growth it fy*ai"iin is essential to determine the potential factors r-esponsible for thek occurrences. The effec...
