THE PROGRAMME WILL INCLUDE THEORETICAL AND PRACTICAL TRAINING ON THE PROPER HANDLING, REPAIR AND SERVICING OF FARM CULTIVATORS, MOTORISED SPRAYERS AND THE SPRINKLER IRRIGATION SYSTEM.
DISCUSSION SESSIONS WILL ALSO BE HELD DURING WHICH TECHNICAL ADVICE WILL BE GIVEN ON WAYS TO SOLVE EVERYDAY MECHANICAL PROBLEMS.
THE COURSE, THE FIFTH IN THE SERIES, FORMS PART OF A REGULAR PROGRAMME OF TRAINING ACTIVITIES ORGANISED BY THE DEPARTMENT.
OTHER ACTIVITIES IN THE PIPELINE INCLUDE A SERIES OF ONE-DAY OR HALF-DAY SEMINARS ON THE SAFE HANDLING AND USE OF ROTARY CULTIVATORS.
SEWAGE EFFLUENTS A BOON TO POND FISH GROWTH
****
AQUACULTURE RESEARCH BY THE AGRICULTURE AND FISHERIES
DEPARTMENT HAS DEMONSTRATED THE POTENTIAL OF USING SEWAGE EFFLUENTS FOR POND FISH PRODUCTION, FISH CULTURE DEVELOPMENT OFFICER, MR ALFRED SIN, SAID TODAY (THURSDAY).
RESULTS OF FISH CULTURE TRIALS CONDUCTED IN OXIDATION PONDS AT THE SHEK WU HUI SEWAGE TREATMENT PLANT IN RECENT YEARS SHOWED THAT SELECTED SPECIES GREW IN SEWAGE EFFLUENTS AT A HIGHER RATE THAN IN COMMERCIAL PONDS AND THE YIELD WAS ENCOURAGING, HE SAID.
SPEAKING AT AN INTERNATIONAL SYMPOSIUM ON RECYCLING OF ORGANIC WASTES ORGANISED BY THE CHINESE UNIVERSITY OF HONG KONG, MR SIN SAID THAT THE INLAND FISH CULTURE INDUSTRY IN HONG KONG HAD DEVELOPED STEADILY IN THE 1970'S AND EARLY 80'S.
AS MOST PONDS WERE RAIN-FED, WATER SUPPLY WAS A MAJOR CONSTRAINT TO DEVELOPMENT. OTHER CONSTRAINTS WERE INCREASING PRICES OF FEED-STUFFS WHICH RESULTED IN HIGHER PRODUCTION COST AND THE LOSS OF POND AREAS TO URBANISATION AND DEVELOPMENT, HE ADDED.
+ON THE OTHER HAND, THE DISPOSAL OF SEWAGE AND TREATED EFFLUENTS, RICH IN NUTRIENTS, IS BECOMING A GLOBAL PROBLEM,
+THE DISPOSAL OR USE OF THESE EFFLUENTS IN FISH CULTURE IS THEREFORE GIVEN PRIORITY IN MANY COUNTRIES.+
