QUESTION 2

  • (i)               Identify specimensJ and K.                                            [2 marks]
  • (ii)  State three functions of specimen J in a fish pond.          [3 marks]
    (iii) Mention four differences between specimens J and K.     [8 marks]
  • Give two methods of applying specimens J and K in a fish pond.     [2 marks]
_____________________________________________________________________________________________________
OBSERVATION

This question was poorly attempted by the candidates.  In 2(a)(i), most of the candidates were able to identify specimens J (Cow dung) and K (Urea). However, in 2(a)(ii-iii), most of the candidates could neither state the functions of specimen J (Cow dung) in a fish pond nor mention the differences between specimens J (Cow dung) and K (Urea).  Also, majority of the candidates could not give the methods of applying specimens J (Cow dung) and K (Urea) in a fish pond as required in 2b.
The expected answers include:
2(a)(ii) Functions of Specimen J (Cow dung) in a fish pond
                -   Fertilize the pond/provides essential nutrients
                -   It improves the condition of the pond
                -   Increases fish production without risk of dietary diseases
               -   Stimulates growth of natural fish food organism/plankton
(iii)       Differences between Specimens J (Cow dung) and K (Urea)
                                    J (Cow dung)                                                  K (Urea)
               -   Fertilizer of animal/natural/organic origin            Synthesized/man made
                                                                                                fertilizer/artificial/inorganic
               -   Large quantity required to fertilize a pond          Small quantity required to fertilize
                                                                                                a pond
               -   Smelly and application can be messy                  Easy to apply
               -   Locally produced or gotten from the                  Industrially produced
                   waste of cattle
              -   Very slow in terms of reaction time in                 Fast in terms of reaction time in the
                  the pond                                                                pond
              -   Cheap to procure/economical                               Expensive to procure
              -   More mineral nutrients                                     Nutrient availability is specific
            (b)        Methods of applying Specimen J (Cow dung) and K (Urea) in a fish pond
                         -   Broadcasting/spraying
                        -   Sac method/spot
