Title

PRODUCTION OF WASTES IN AQUACULTURE AND ITS EFFECT ON AQUATICS CULTURE

Pages

  -

Abstract

 ENVIRONMENTAL EFFECT OF AQUACULTURE METHODS, VALUE AND REPETITION OF WASTES DISCHARGE FROM FIELDS TO ENVIRONMENT AROUND IS AMONG IMPORTANT FACTORS. THE EFFECT OF WASTES OF FISH PONDS ON COLLECTED WATERS ON LOCAL CONDITIONS. WASTE PRODUCTS RESULTING FROM FEEDING AND METABOLISM IN THE FIELDS OF AQUACULTURE INCLUDE WASTES OF FOODS AND DISCHARGE MATERIALS, BY PRODUCTS OF METABOLISM OF REMNANTS OF HERBICIDES AND BIOCIDES. FOOD WASTES DEPEND ON FACTORS INCLUDE FOOD BEHAVIOR OF CULTURE CREATURES, FOOD CONSISTENCY IN THE WATER, METHODS OF FOOD DISTRIBUTION AND TIME OF FEEDING. DECOMPOSITION OF MANURE IS VERY VARIABLE AND IT DEPENDS ON ANIMAL SPECIES, ITS FOOD ' NATURE, STORAGE AND TRANSPORTATION OF FOOD AND WEATHER CONDITIONS. ENRICHING AN AQUACULTURE FIELD HAPPENS BY DECOMPOSITION OF FOOD WASTES, MANURES, WASTES OF METABOLIC PROCESS AND MORE OFTEN TOO MORE FERTILIZING. THESE RESULT IN TO BLOOM ALGAE IN THE FIELDS OR NEAR THEM. THIS MAY INCLUDE CHANGES IN COMPONENTS OF PHYTOPLANKTON AND DECREASE IN CREATURES THAT SHAPE OF FEEDING ALL KINDS OF CULTURED CREATURES. ENRICHING BOTTOM SEDIMENTS IN THE FIELDS AND IN THE CAGES OF OPEN WATERS PROVIDE HIGH CONDITIONS FOR BACTERIA POPULATION. TO SURVEY ENVIRONMENTAL EFFECT OF AQUACULTURE IT IS NECESSARY TO MEASURE CONCENTRATION OF FOODS IN THE WATER AND DISCHARGE VALUE OF NUTRIENTS FROM FIELD TO THAT WATER ECOSYSTEM IN UNIT TIME AND WATER STORAGE TIME IN THE AREA. ALTHOUGH BASICALLY ALL KINDS OF WASTES PRODUCED IN AQUACULTURE FIELDS ARE EQUAL BUT DEPEND ON CULTURE OPERATION AND SPECIES WE SEE DIFFERENCES IN THEIR COMPONENTS QUALITY AND QUANTITY. MORE DATA RELATE TO INTENSIFIED SYSTEMS OF SALMON CULTURES IN CAGES IN MODERATE WEATHER. ALTHOUGH THESE PROCESS HAVE NOT PRONOUNCED DIFFERENCE BUT CAPABILITY OF THESE DATA IS NOT OBVIOUS IN DIFFERENT CLIMATES. HOWEVER THESE DATA CAN PROVIDES FIELDS FOR NEXT RESEARCHES AND BECOMES BASE OF SPECIAL SURVEY.
