FISHERIES THEORY 

(1ai) Fishing net.

(PICK ANY THREE)

(i) Rinse the net with fresh water after each use to remove
salt, dirt, and debris.
(i) Inspect the net regularly for holes or fraying and repair
them immediately
(ii) Dry the net thoroughly before storage to prevent mold
and rot.
(iv) Store the net in a cool, dry place away from direct
sunlight to prevent degradation
(v) Treat the net with antimicrobial solutions to prevent
bacterial or fungal growth

(i) Rinse the canoe with fresh water after each use to
remove dirt, salt, or other contaminants.
(i) Inspect the canoe for cracks, leaks, or damage and repair
them promptly.
(ii) Store the canoe in a shaded, dry area to prevent sun
damage and degradation of the material.
(iv) Apply a protective coating or paint to the hull to preserve
its condition and prevent wear.
(v) Ensure the canoe’s hardware (like paddles, seats, or
fittings) is well-maintained and tightened regularly.

(2a)

(PICK ANY FIVE)

(i) Select a suitable site with good water supply and proper drainage.

(ii) Clear the area of any vegetation, debris, or obstacles.

(iii) Mark the boundaries of the pond and determine the shape and size.

(iv) Excavate the pond to the desired depth, ensuring proper sloping.

(v) Construct an inlet and outlet for water flow, ensuring proper drainage.

(vi) Line the bottom with clay or compact soil to prevent water leakage.

(vii) Fill the pond with water and allow it to settle for a few days.

(viii) Install aeration systems or water fountains if necessary.

(ix) Check for any leaks or issues and make necessary adjustments.

(x) Add appropriate fish species and ensure regular maintenance.

 

(2bi)

(PICK ANY THREE)

(i) Clear the pond of debris, weeds, and any obstacles.

(ii) Level and shape the pond to ensure proper water distribution.

(iii) Fill the pond with water, ensuring a steady supply.

(iv) Test the water for quality, including pH, temperature, and oxygen levels.

(v) Apply lime to adjust pH levels if necessary.

(vi) Fertilize the pond to stimulate plankton growth for fish feed.

(vii) Install proper inlet and outlet systems for water flow and drainage.

(viii) Ensure the pond is free of predators and harmful organisms.

(ix) Allow the pond to settle for a few days before introducing fish.

(x) Stock the pond with appropriate fish species for the environment.

 

(2bii)

(PICK ANY FOUR)

(i) Agricultural lime (calcium carbonate)

(ii) Quicklime (calcium oxide)

(iii) Hydrated lime (calcium hydroxide)

(iv) Dolomitic lime (calcium magnesium carbonate)

(v) Burnt lime

(vi) Slaked lime

 

(2c)

(PICK ANY FOUR)

(i) Reduces light penetration, affecting the growth of aquatic plants and plankton.

(ii) Decreases oxygen levels in the water, which can stress fish.

(iii) Impairs fish feeding behavior, as they rely on clear water to locate food.

(iv) Increases the risk of disease by limiting water quality and increasing pathogens.

(v) Causes sedimentation, which can clog gills and harm fish.

(vi) Reduces the overall aesthetic and environmental quality of the pond.

 

(2d)

(PICK ANY FOUR)

(i) Provide a balanced and nutritious diet to promote health and reproductive performance.

(ii) Ensure proper water quality, including maintaining appropriate temperature, pH, and oxygen levels.

(iii) Regularly check for diseases and parasites, and treat them promptly.

(iv) Maintain a proper breeding environment, including suitable breeding tanks or ponds.

(ii) Perform periodic health checks and remove any sick or weak fish.

(vi) Rotate or rest broodstock periodically to prevent overuse and ensure continued fertility.

(vii) Provide ample space for movement and reduce stress by avoiding overcrowding.

(viii) Manage breeding cycles to ensure the right timing for reproduction.
