Question 2
- (i) Group specimens C, D, E, and F into passive and active fishing gear.
(ii) Give two reasons for the groupings in 2(a)(i). [4 marks]
- State one advantage of specimenC over specimen E. [1 mark]
- (i) List two components each of specimens C and E.
(ii) Mention two ways of maintaining specimen F. [6 marks]
- Name two materials used for the construction of specimen D. [2 marks]
Observation
This question was attempted by many candidates and their performance was good. However, many candidates had issues classifying fishing gears into passive and active gears as required in Question 2 (a)(i).
The expected answers include:
(a) (i) Classification of fishing gear
Passive gear
Specimen D - Fish trap
Specimen E - Hook and line
Active gear
Specimen C - Drag net
Specimen F - Cast net
(ii) Reasons for the classification
- Active gear require additional effort to make a catch
- Active gear have to be moved to catch fish/needs to be operated to
make a catch
- Passive gear are stationery/does not need additional effort/could make a catch without an operator
(b) Advantage of specimen C (Drag net) over specimen E (Hook and line)
- Specimen C (drag net) catches many fishes at a time while specimen E
(Hook and line) catches one fish at a time
- Fish is retrieved immediately while the fish on hook might have become stale
(c) (i) Components of specimen C (Drag net)
- net
- float line /head rope
- lead line /weight line /sinker line/foot rope
- floater
- sinker / lead / weight
Components of specimen E (Hook and line)
- line / rope / twine
- hook
- pole / handle
- floater
(ii) Maintenance of specimen F (Cast net)
- remove trapped debris and entanglements
- wash and dry after use
- mend torn parts
- store in cool dry place
(d) Materials used for construction of specimen D (Fish trap)
- wiremesh
- line /rope /twine
- bamboo /palm frond /reed/iron or steel rod/cane
