11(a) Methods : 1. Use of quality breeds
Produce high quality yields Breeds matured earlier The breeds which are being developed is more resistant/tolerant to drought, diseases and pests
2. Use of modern technology The use of modern machines such as tractors,
mechanical harvesters and power tillers speed up the planting and harvesting of
crops. Can increase the efficiency of labour, water, plant nutrients and invested capital used
3. Education and guidance for farmers Educate the farmers to use quality breeds and
modern technology (to increase the yields of their crops).
4. Research and development Agencies and government institutions (FAMA,MARDI,MPOB and UPM) conducting research and development activities, provide training and education related to agriculture, livestock and fisheries.
5. Efficient land management Proper management of agricultural land is necessary which ensuring the land remains fertile and to prevent soil erosion
6. Optimum uses of land and irrigated areas Integrated systems involve rearing livestock and planting crops on the same farmland
7. Genetically modified food Food is produced from a genetically modified organismes. Food produced is altered to produce desirable
qualities such as resistance to pest or inclement weather

11(b) Problem: To keep the fishes for a period of time Methods Of Preservation: 1. Freezing:
The fishes are kept at very low temperatures of -180C and below
The low temperatures do not kill the microorganisms but will stop the microbial activities
2. Canning The fish and the cans are heated at 1210C to kill
microbes and fungi. The hot food is placed into the sterilized
cans and are sealed airtight.
3. Dehydration Water is removed from the fish by drying the
fish under the sun or smoking. The growth of microbes are prevented
without the presence of water. Note: Any 3 methods with explanation
Methods according to priority: 1. Freezing 2. Canning 3. Dehydration
Reason of choice: Freezing is the best method to keep the fish for a longer period of time because at low temperature the microbe activities are stopped. (Note: Any relevant reason)
