Question 1

Question
According to the FAO, Fish In Fish Out is the number of tonnes of wild fish that takes to produce a tonne of farmed fish. The calculation is done according to the following formula:
Answer
  • FIFO = ((FM in feed%)/(FM yield from wild fish%) + (Level of FO in the feed)/(yield of FO from wild fish %))xFeed: gain ratio;
  • FIFO = ((FO in feed%)/(FM yield from wild fish%) - (Level of FM in the feed)/(yield of FO from wild fish %))xFeed: gain ratio
  • FIFO = ((FM in feed%)/(FM yield from wild fish%) + (Level of FO in the feed)/(yield of FO from wild fish %))/Feed: gain ratio
  • FIFO = ((FO in feed%)/(FO yield from wild fish%) - (Level of FM in the feed)/(yield of FO from wild fish %))xFeed: gain ratio
  • FIFO = ((FO in feed%)/(FM yield from wild fish%) +(Level of FM in the feed)/(yield of FM from wild fish %))/Feed: gain ratio

Question
Which alternative on carbohydrate id correct?
Answer
  • They represent an expensive valuable source of dietary energy for non-carnivorous fish and shrimp.
  • Their careful use in food can boost the degradation of protein.

  • False

Question 28

Question
Check the boxes of the alternatives that are correct or true about carbohydrates.
Answer
  • Starch is the main carbohydrate used in aquafeeds.
