BACTERIAL ABUNDANCE MONITER AND CONTROL IN THE SEAWATER SYSTEM OF LAMINARIA SUMMER SPORELING CULTURE STATIONS |

| Abstract: | The bacteria that may induce disease of Laminaria summer sporeling at culture stations can be commonly found in coastal seawater. In order to prevent these sporelings from disease it is necessary to monitor and control the bacterial abundance in cultivation seawater system. The availability of nutrient in coastal area is the main factor which influences the bacterial abundance in seawater. Pumping site should be carefully selected in order to get better quality seawater with low nutrient. In coastal area bacterial abundance varies with the tidal cycle, minimum abundance usually occurs at high tide. Heterotrophic bacterial population increase apparently once the seawater is stored in large tanks, and is greatly influenced by the available nutrient level of the seawater. Sand filteration is an effective way in reducing bacterial abundance in seawater system at Laminaria sporeling culture station. These sand should always be washed to keep effectiveness of its filteration. Many drafting juvenile Laminaria in culture tanks will accelarate bacteria multiplication in seawater pomptly. Those debris should be removed before reusing these seawater. |
