Feeding Response and Feeding Performance

Which of the following best define feeding response?

• The amount of feed to be given to fish per day

• The amount of vigor that fish display in consuming feed

• The amount of times fish in a holding unit is fed each day

• The amount of feed required to produce one unit of fish

Which of the following may result in FCR value of above 2?

• Fish are under-fed

• Fish are over-fed

• Survival rates at harvest are high

• Feeding maintenance ration when carrying capacity is reached in holding unit

Which of the following is an importance of observing feeding response?

• To allow visual assessment of stock in a holding unit

• To allow farmer to sample fish in holding unit

• To allow calculation of DFR

• To enable farmer to determine partial harvesting is required

Which of the following is NOT a criteria for judging feeding response?

• Excellent

• Poor

• Good

• Moderate

Which of the following best describe the judging criteria Excellent feeding response?

• Fish are sluggish

• Feed administered are all consumed within 5-10 minutes of feeding

• Fish do not come to feed

• Feed administered are all consumed within 15-20 minutes of feeding

Which of the following is the purpose of training fish to feed by response?

• To deliberately create competition for food

• To result in uneven gorwth rates

• To achieve a higher FCR

• To allow underfeeding or overfeeding of stock

Which of the following is amethod to evaluate feeding performance?

• Daily Feed Ration (DFR)

• Feed Conversion Ratio (FCR)

• Feeding Frequency

• Feeding Response

Which of the following can be indicated by FCR?

• Average body weight of fish

• Performance of person feeding the fish

• Growth rate of fish

• The feeding frequency adopted

Which of the following best describe FCR value of 2?

• 2 kg of fish is required to produce 1 kg of feed

• 2 kg of feed is required to produce 2 kg of fish

• 2 kg of fish is required to produce 2 kg of feed

• 2 kg of feed is required to produce 1 kg of fish

In grow-out operations of aquaculture, a good FCR should be around which range?

• 1.5-2

• 2-2.5

• 2.5-3

• 3-3.5
