Activities
Learners' Activities
  1. Divide the class into three (3) groups.
  2. Using draw lots, a member of the group will pick on it.
  3. With a given value, construct a brackish water fishpond layout using a manila paper, pentel pen and ruler. Identify if it is Conventional Pond System, Modular Pond System or Multiple Stock/Harvest System. Indicate its measurement and show its computation on a bond paper.
  4. Explain what type of freshwater fishpond system (Barrage pond type or Diversion type) is prefer to use.
  5. Choose two members of the group to present it on class.
Teacher Activities
  • Prepare an overhead projector to guide students' activities.
  • Give instructions on what to put in the manila paper.
  • Help students who have questions.
  • Ask questions to check students' status.
    • Do you know how to get the scale?
    • Why do you prefer to choose that kind of lay out and system?
    • Where will you put your main gate and secondary gate?

POST TEST

I.             Identification
Direction: Identify the following and write your answer on the blanks provided.

________________ 1. Is an artificial body of water surrounded by dikes and with
accessories such as gates, pipes and canals to facilitate water management.

________________ 2.Compartment of fishpond where fish fry to fingerlings size are being reared.

________________ 3. It is the largest compartment in the pond system. Used for raising fingerlings up to marketable size.

________________ 4. Freshwater pond layout where it is consist of one sluice gate and long water supply canal.

________________ 5. Consist of one sluice gate; long supply canal and a secondary gates provided to different compartments of progressively increasing areas.

________________ 6.A pond type which has a diversion canal to serve as a passageway of water from the main water body, e.g. creek, brook and the like.

________________ 7. A type in which ponds are built parallel to each other and each
pond of which has an inlet and an outlet.

________________ 8. A freshwater pond layout where it has one sluice gate; wide and
short supply canal; and secondary gates in the different compartments.
