This question was poorly attempted by the candidates.  In 1(a)(i – ii), majority of the candidates could neither define culture fisheries not explain the attributes of a culturable fish species.  However in 1(b), most of them were able to mention fish culture facilities.
Further to this, in 1(c-d), majority of the candidates could neither list the types of fish ponds nor state the methods of lime application in a fish pond.
The expected answers include:
1 (a) (i) Meaning of culture fisheries
                         Fish culture is the production/rearing/domestication of aquatic organisms in a
                        Controlled/confined environment
                                                          OR 
                         Fish production under artificial environment           
               (ii)    Explanation of attributes of a culturable fish species
                      -    Hardiness: the fish must be hardy, must be able to withstand handling conditions/adaptive
                      -    High survival rate:  large number/percentage must survive in captivity
                        -    Compatibility:  must be able to co-exist with other fish species i.e. polyculture
                      -    Acceptance of artificial feed: must be able to accept man made or compounded feed
                      -    Acceptability to consumers/marketability: must be marketable and accepted by the target consumers
                      -    Breeding under captivity: must be able to reproduce or be induced in artificial Environment
                      -    Tolerance to poor water: must be able to grow and thrive under poor water Conditions
                      -    Fast growth: must have good growth rate and reach market size within a short time/High feed conversion efficiency
                      -    Disease resistance: must be able to withstand a wide range of fish diseases
                   
(c)        Types of fish ponds
                        -     Earthen pond
                       -     Excavated ponds/dugout ponds
                        -     Embankment ponds/contour/paddy ponds
                        -     Hilly ponds/barrage/ravine ponds
                        -     Concrete tank
                        -     Plastic tank
                        -     Fibre glass tank
                        -     Wooden tank
                        -     Tarpaulin tank      

 (d)      Methods of lime application in a fish pond
                        -     Broadcasting directly into the pond water surface
                        -     Broadcasting directly on pond bottom/dams side
