1Why is site selection critical before constructing a freshwater fish pond?
A.It determines water availability, soil suitability, drainage, and long-term productivity
B.It only decides the colour of the pond water
C.It replaces the need for any dyke construction
D.It makes liming illegal
Explanation: Good sites provide reliable water, suitable soil for holding water, workable topography for dykes, and drainage. Poor sites raise seepage, flooding, and management costs and lower yield.
2Which soil property is most desirable for earthen freshwater culture ponds?
A.Soil with enough clay to reduce seepage while still workable for dykes
B.Pure coarse sand that drains completely overnight
C.Solid impermeable rock with no soil cover
D.Loose gravel that cannot form embankments
Explanation: Clayey or clay-loam soils hold water and allow dyke building. Excessively sandy or gravelly soils leak; bare rock prevents conventional embankment ponds without liners.
3What is the main function of pond dykes (embankments)?
A.To retain water at the planned depth and prevent uncontrolled flooding or leakage at the margins
B.To generate dissolved oxygen by photosynthesis
C.To replace all need for inlet and outlet control
D.To feed fish automatically
Explanation: Dykes enclose the pond, hold water, and protect against overflow when properly designed with freeboard. Aeration, feeding, and water exchange still need separate management.
4During pre-stocking pond preparation, why is complete drying of the pond bottom often recommended when feasible?
A.Drying helps mineralise organic matter, reduce pathogens and unwanted organisms, and firm the bottom
B.Drying permanently removes all minerals needed by fish
C.Drying replaces liming in every soil type without exception
D.Drying is done only to change the fish's genetic identity
Explanation: Sun-drying oxidises organic wastes, reduces disease carriers and weed seeds in surface mud, and improves bottom condition before liming and manuring. It does not replace all other preparation steps.
5What is a primary purpose of liming freshwater culture ponds?
A.To correct acidic soil/water, improve alkalinity buffering, and create better conditions for plankton and fish health
B.To permanently sterilise water so no organisms can live
C.To increase ammonia toxicity as a management goal
D.To remove all dissolved oxygen before stocking
Explanation: Agricultural lime (and related liming materials) raises pH of acid soils/water, improves buffering, and supports productive plankton communities. It is not meant to kill all life or strip oxygen.
6In sequential pond preparation, when is manuring or fertilisation usually applied relative to liming?
A.After liming has been given time to react, so nutrients support a controlled plankton bloom before stocking
B.Immediately into bone-dry acidic mud with no lime ever used, as the only correct global rule
C.Only after fish are harvested and the pond is abandoned
D.Never, because plankton always harms cultured carps
Explanation: Standard culture practice limes first when needed, then applies organic/inorganic fertilisers so natural food develops under improved water chemistry. Exact intervals depend on local protocol, but liming before manuring is the usual logic.
7Why must predatory fishes and unwanted aquatic insects be controlled before stocking valuable carp seed?
A.Predators and insects can consume or injure fry and fingerlings, causing heavy early mortality
B.Predators always increase dissolved oxygen above safe limits
C.Insects permanently raise pond pH to alkaline extremes only
D.Predators replace the need for any feed
Explanation: Snakeheads, murrels, catfishes, and aquatic insects can devastate nursery and early rearing crops. Clearance by drying, netting, or approved control methods protects seed survival.
8What is a practical reason to provide both a controlled inlet and a controlled outlet on a culture pond?
A.To fill, exchange, and drain water safely while managing water level and quality
B.To ensure water can never be added or removed
C.To guarantee zero seepage through the dykes
D.To eliminate the need for any dyke freeboard
Explanation: Inlet and outlet structures (pipes, sluices, screens) let farmers fill, flush, and harvest/drain while screening unwanted fish. They complement—not replace—sound dyke design.
9Which practice best reduces carry-over of disease organisms between successive culture crops?
A.Drain, dry or treat the bottom, remove organic sludge, and restock only after proper preparation
B.Restock immediately into deep sludge without cleaning
C.Never dry or clean the pond so pathogens stay undisturbed
D.Fill only with untreated water known to contain wild predatory fish
Explanation: Sanitary preparation between crops—draining, desilting, drying/liming, and careful water filling—breaks disease and predator cycles. Skipping sanitation raises mortality risk.
10A farmer finds heavy seepage after first filling a new earthen pond. Which response is most consistent with good construction practice?
A.Investigate soil texture and compaction, consider sealing methods or clay blankets, and correct weak dyke sections
B.Ignore seepage because all ponds must empty daily by design
C.Add only common salt until the pond becomes seawater
D.Immediately overstock at grow-out density to plug leaks with fish
Explanation: Seepage is a soil/engineering problem: inadequate clay, poor compaction, or dyke faults. Sealing (clay, bentonite, liners) or reconstruction is appropriate; fish cannot fix structural leaks.
